astrophotography settings a7iii

The inset image at right in Photoshop shows the scene, the Milky Way above dark trees in my backyard! The other Live View function that works well, but also needs assigning to a C button is the Camera Settings 1 > Focus Magnifier. A great app I found with the A7S and A7RM2 was Digital Filter which is good for city lights below and dark sky above, you can capture two images in camera with different settings for the above and below and get a RAW combined in camera image to use in post instead of Photoshop blending, again just for thought. It was not supplied to me by Sony in return for an “influential” blog post. You can push it to maybe 20 seconds if you won't be looking at it in a large size (ie. NIKON: I deducted points for real-time video of auroras – the D750 can do them but is pretty noisy with the high ISOs needed. For astrophotography, I carry the Sony 16-35mm f/2.8 G Master, Sony 12-24mm f/4 G, the Zeiss Batis 18mm f/2.8, and now, the low light monster Sony 24mm f/1.4 G Master. Real-time video of auroras is not possible with anything like this quality with the Nikon (I’ve used it often), and absolutely not with the Canon. https://www.youtube.com/watch?v=en4eeK33UoE Further info on the algorithm and its effects (info is for A7RII/RIII, but should apply to A7III): I used the Metabones Canon-to-Sony adapter when attaching the Sony to my telescopes using my existing Canon telescope adapters. I expected the new BSI-equipped Sony to better the Nikon by about a stop. But to develop all the images from Sony, Nikon, and Canon equally for comparisons, ACR is the best choice. They do not perform differently when in a large sensor vs in a small sensor. Shooting the stars successfully requires the right camera settings along with the ability to manually focus on the stars. You will see more detail with smaller pixels but not more noise unless you are cropping photos from these different sensors to the same number of pixels. Dark frame subtraction using Long Exposure Noise Reduction removed most – but not all – hot pixels from thermal noise. It varies with even Canon full-frame. Up to now my report on the Sony a7III hasn’t shown as glowing a performance as all the YouTube reviews would have you believe. Sony not performing as good as competitors? I think any really ‘serious’ astrophotography users would be looking at a dedicated astro camera (CCD or CMOS), but know you can get some amazing results with a ‘normal’ quality camera such as those compared in this review. Display Options The images take up so much computer storage space! Full-frame and cropped-frame cameras with similar sized pixels have similar levels of noise. As the images below show, there is a very slight one-pixel-level softening that kicks in at 4 seconds and longer but it did not eat or wipe out stars. The A73 has the following shooting modes: Intelligent Auto: All settings are handled by the camera and it’ll even try to identify the scene from the list of 11 scenes (which we’ll go through in a bit). Levels of luminance and chrominance noise were excellent and similar to – but surprisingly not better than – the Nikon D750. For the intervalometer, I don’t see a setting for exposure duration, just interval, start time, and number of exposures. Cannon doesn’t seem to be even trying to catch up. I’m not here to knock Sony, in fact I shoot with one, using an A7R for my astro work because of this issue. I can assure you that even the ace programmers of Raw development software who I have spoken to are puzzled by this as well. For nightscapes I would never shoot at a lower ISO than necessary with hopes of boosting exposure later. It’s unfair to blame just the hardware or the software. We shoot everything on manual. But the a7III should do the job for bright auroras, the ones with rapid motion worth recording with video, plus offer 24 megapixels for high-quality stills of all sky subjects. Turning on LENR did eliminate most hot pixels in long exposures, but not all. I had originally remarked that this useful function was missing. The latest iteration of the menu interface is much improved on the a7III. Dual Card Slots  Menu > Camera Settings 2 > AF System (Not available with native E-mount lenses) This is actually the most important new setting on Sony a7RII cameras. I wanted to reach out to the community and see if anyone has great astrophotography settings they've used. This is an annoying flaw, though applying “flat fields” or ad hoc local adjustments should eliminate this. This has the zoom or magnifier button. And in identically exposed images. But this test re-emphasized my thoughts that Canon DSLRs remain the best for long-exposure deep-sky imaging where you can give images as much exposure time as they need, while the ISO invariant Sony and Nikons exceed at nightscape shooting where exposures are often limited and plagued by dark shadows and noise. Yes, that’s the point. “Noise” is randomness in a physical quantity, or in the method of measurement, more or less. ( Log Out /  Star Eater The S/N ratio is determined by the individual pixels — they don’t know how big a sensor they belong to and won’t behave differently in a cropped sensor vs a large sensor. I would not recommend the a7III for deep sky. The 2008-vintage 5D MkII had a 5-frame buffer! Instead, you have to go to the Camera Settings 2 page, then select Still Image–Custom Key. See http://docs.view.tl/#camera-specific-notes, With the Alpine Laboratories Radian2, exposure ramping is not possible with a Sony, only basic shutter triggering. “The 2008-vintage 5D MkII had a 5-frame buffer!” I saw no great benefit from the BSI sensor. SONY: I deducted marks from the Sony a7III for deep-sky imaging for its lack of a light frame buffer, poor red sensitivity, odd LENR performance, and purple amp glow not seen on the other cameras and that dark frames did not eliminate. TL;DR Conclusions. What we are seeing with “green” stars (in both the Sony and in the Nikon) is an effect of the de-Bayering of those cameras’ raw frames that varies considerably depending on the Raw developer you use and, in the case of Raw Therapee, the de-mosaic algorithm selected. They will be the same, because it is the pixel size not the sensor area that matters. Limited Touch Screen Functions  And isn’t that what you care about? It’s not the debayering which causes the color shift, as those stars are white in images with 3.2 s and become green at 4 s exposure time. The amount collected also fluctuates to a lesser or larger extent, depending on the quantum efficiency of the collector (pixel). You’re comparing noise in images where there’s a lot of light(which is equivalent to the fact that your test images don’t have really deep shadows that we encounter in astrophotography). For most people, the a7III is going to downright rock at low-light and landscape astrophotography. This would be much tougher to eliminate in deep-sky images where the extreme contrast boosts we typically apply to images of nebulas and galaxies will accentuate any odd glows.

Shutter speeds can be as slow as 1/4-second, allowing real-time aurora shooting at reasonable ISO speeds. Jim Kasson’s testing (https://www.dpreview.com/forums/post/61074932) provides strongly conclusive evidence that it is still present, and your first comparison shot with the Canon 6d shows small stars in the Sony that are characteristically ragged and with a dominance of green colour – exactly the features explained in Mark Shelley’s reverse engineering of Sony’s latest spatial filtering algorithm. Thanks! The firmware, pixel size and pixel characteristics are also all the same. Since night photography has become a bigger part of my hobby life, I’ve been considering this as a replacement for my aging a6000. Surprise! CANON: The 6D MkII’s lack of an ISO invariant sensor rears its ugly head in underexposed shadows in dark-sky nightscapes. Even with Canons that have a Bulb Timer for exposures >30s you can’t use it with the internal intervalometer. But the A7III (as well as the A7RII, A7SII, A7RIII and A9) is still “eating stars”. Light Frame Buffer in LENR [���][deleted] 0 points1 point2 points 2 years ago (0 children). Is it iso invariant enough that it doesn’t matter, or are certain iso’s slightly better in your opinion for night sky images than the tier 2 base iso of 640? Image quality was just fine. Intervalometer — NOW INCLUDED! You’re saying the a7III will show less noise than the competitors when used under very low light conditions. Post was not sent - check your email addresses! Sensors with 4 micron pixels will have more noise than sensors with 6 micron pixels, no matter what size the sensor is. Hi, it all depends on what you want to buy or already have for lenses. Thanks for reading! Would you say the Sony is worth the $500 difference in price to the Nikon? I show only the Sony and Nikon compared here, shot at the common range of ISOs used for nightscape shooting, 800 to 12800. The 500/focal length rule for exposition time is also usually working to avoid star trails, but it can wield different results depending on how far from the Polar star you are actually aiming. To my eye, the difference is nothing like the huge wiping out of stars reported and shown at Lonely Speck. I just read your evaluation of the Sony A7III in Sky & Telescope. In that case you would get a wider angle photo with the larger pixels with less noise simply because you are using a larger part of the sensor. Why would that be? The disadvantage is that full-time live view draws more power, with mirrorless cameras notorious for being battery hungry. Exceptions are images taken for star trail stacking and for time-lapses, images that must be taken in quick succession, with minimal time gap between frames. It offers 4K (or more precisely UltraHD) video recording for videos of 3840 x 2160 pixels. All three are “entry-level” full-frame cameras, with 24 to 26 megapixels and in a similar price league of $1,500 (Nikon) to 2,000 (Sony). Does adapting the Roki SP on the Sony body somehow compromises the image quality (in terms or sharpness, distortion, coma…)? The advantage of purely electronic viewing is that the image you are previewing matches the image you’ll capture, at least for short exposures. I tested a Sony a7III purchased locally. Thank you, Alan! Interval meter is here now! This comparison will not show the real situation with the noise level. An alternative would be an LCD screen that was touch sensitive. — Alan. To the eye, the Sony and Nikon look very similar for noise levels, just as in the moonlit scene. When used with the Genie Mini (below) the Sony fired at only every other pulse if it was in Single shot mode, an oddity of Sony’s firmware. Overall, I’d rank this lens number two out of the four lenses in this post. Best Astrophotography Settings for A7iii. And neither are 4K. The effects of the algorithm are clearly visible in your test images when comparing 3.2 and 4 s exposures. I have updated the Review with some new tests to address questions raised by some of the commenters. That’s worth a check, too. Because by definition, noise is the randomness in the collected signal… (Of course, bad electronics, high dark current, etc, could cause the final conversion and readout of the photons to electrons exhibit a lot of noise. This does a fine job smoothing frame-to-frame flickering in time-lapses, something the Canon cannot do. Also, when boosting the exposure a lot in processing, the images taken with LENR on showed more shot and read noise than non-LENR frames. The cameras were on a Star Adventurer Mini tracker to keep stars pinpoints, though the ground blurred in the longer exposures. The thinner body allows the use of lenses from any manufacturer, albeit requiring the right adapter, an additional expense. I have learned that night shots below 800 are noisier so for what it is worth. Wow! Perhaps I’ll add examples to show that, but I would invite you to take your own Raw files of tracked star images shot with a Sony, Nikon, and Canon camera and develop them with Adobe Camera Raw, Capture One, DxO, Affinity, Luminar, ON1 Photo RAW, and Raw Therapee’s various modes. In testing the Sony a7III I ignored all the auto functions. You mention with the a7iii that it’s not completely iso invariant and that the files when pushed 4 stops were not as clean as the shot taken at iso 6400. I made that comment in the blog. I wanted to reach out to the community and see if anyone has great astrophotography settings they've used. 1.1 Quality = RAW for best quality. However, like other brands’ internal intervalometers Sony’s is good only for exposures up to 30 seconds long. Here’s the cool part: Take the same lens and adapter and mount it on the a6300 or a6500 and now you have a 25.5mm lens. All images are equally well exposed. 2. Yes, they are not as bad anymore as on earlier A7RII firmwares, which originally created all the fuzz. The Sony shows a lot of green stars with or without LENR. Solar System astrophotography (Lunar, Solar and planetary) Photographing the Moon and the Sun is known, respectively, as lunar astrophotography and solar astrophotography. REDDIT and the ALIEN Logo are registered trademarks of reddit inc. π Rendered by PID 30836 on r2-app-0ac30b6d0efcd6480 at 2020-12-14 14:43:06.642542+00:00 running 85e58d4 country code: JP. I’ve noticed you’ve used the Rokinon 14mm SP on the a7iii in your noise test. The Canon 5D MkIV is $1000 more than the Sony here in Canada and is 30 Mp not 24 like the others, so not comparable in price or spec. What more do you want? Thanks for the suggestion. Hurray! The Canon is free of any such issue – stars are naturally colored whether LENR dark frames are applied or not. As versatile as a mirrorless camera is for lens choice, making use of that versatility requires buying the right lens adapter(s). Please have a look at them again. This is wonderful for taking a set of noise-reduced deep-sky images for later stacking. In most shooting situations, I found using LENR provided the overriding positive benefit of reducing hot pixels. And, as I found, the Sony might need to be placed into Continuous shooting mode to have the shutter fire with every trigger pulse from the motion controller. A few remained. Stars 1 or 2 pixels wide are a little too colorful! This is on paper the best lens for astrophotography today, but it does come with a few flaws: it is very big and heavy and coma correction is not exactly as perfect … Is the a7III as good for low-light video as the Sony a7s models, with their larger 8.5-micron pixels? As photographers age, this becomes a more essential feature! This Sony lens review intends to look for what can be classed at the best lens for Sony A7iii astrophotography. For astrophotography, none of those auto functions are of any value. These settings can be found in the Camera Menu Tab (1) on Page 2 & 14 respectively. This is a very excellent and demanding review with a lot of effort on your part using 3 cameras at one time “BRAVO”. In Movie Mode ISO speeds go up to ISO 102,400, but are pretty noisy, if unusable at such speeds. This allows the Live View image to reflect the camera settings in use, better simulating the actual exposure, even without Bright Monitoring on. Eye AF Eye-AF is one of the most powerful features you will find in the Sony A7iii and it is one of the advantages Sony has over Nikon and Canon. I use a Canon T5i right now as I’m new to the craft. Some time-lapse controllers are able to connect to a camera through its USB port and then adjust the ISO and aperture as well, for ramped “holy grail” sunset-to-Milky Way sequences. That’ll be a good test to make. At 30 fps, 4K videos are cropped with a 1.2x crop factor. Yes, the a7III softens stars and noise slightly but I do not consider it to be “eating stars.” Stars are all there, to the same limiting magnitude in shots taken with other camera brands. Compact size and lighter weight, yet offering all the image quality of a full-frame DSLR. For example, the TimeLapse+ View (see http://www.timelapseplus.com) works great for automated holy grails, but the developer recommends that with most Sonys the minimum allowed interval between shots is longer (8 to 14 seconds) than with Canons and Nikons. Pixels, or photosites, do not “know” how large a sensor they belong to. USB Power  Thank you Sony! Change ), You are commenting using your Facebook account. For elimination of hot pixels from thermal noise I prefer to use Long Exposure Noise Reduction when possible for nightscape and deep-sky images, especially on warm summer nights. I've watched a couple videos and there seems to be some major noise/star eater if you use any ISO over 800 (its a variable ISO in the Cameras) I'm heading to Zion National park and I'm only going to get one crack at nailing this so was hoping someone could give me some advice of successful settings they've used? https://blog.kasson.com/a7riii/the-sony-a7riii-eats-stars/ Just info for those who have never seen the apps. Doing two shots one below for the brightness (lower ISO/higher f//slower SS or any combination) and another for the sky above (last shot) (just opposite of first) getting a combo adjustable before saving and getting a raw to work in post. Or is this just a theory of how it should behave? use the following search parameters to narrow your results: Proud to be the #1 Camera-Brand Subreddit! I’ve used this new function and it works very well. Only being f/4 is gonna limit you. I love it! It���ll be ok at 3200. This emphasizes just how good the Nikon D750 is. Nikons don’t have this, not even the D810a, and not Sonys. One of the test sets shows just what you asked for – exposures of varying length below and above 4 seconds. In images taken at the same time with other cameras not accused of star eating, the Sony showed just as many faint stars as the competitors. However, all will need the right camera control cable, available from suppliers like B&H. and join one of thousands of communities. However, while the Sony has a Bulb setting there is no Bulb Timer as there is with the Canon. The thing I disagree about has nothing to do with this camera. This feature is little known and utilized, and only Canon full-frame cameras offer it. Really Canon? Astrophotography Camera Settings. Unfortunately, I think that you’re conclusions re star-eater are based more on hope than reality. Use the ISO that will produce a well exposed histogram for the shutter speed and aperture dictated by the scene. Even a supposedly ISO invariant Camera like the Sony can show noise and discoloration in underexposed images boosted later in exposure. The Sony a7III is a superb camera for still and time-lapse nightscape shooting, and excellent for real-time aurora videos. Happy shooting, John. A shorter SS for the wider the Aperture (more lens being used) but learning that even a 10mm lens is 17.86 seconds for Accurate and 35.60 for standard so bulb mode not really needed. Indeed, at slower ISOs and longer exposures, more stars are visible. Instead, for any exposures over 30 seconds long (or time-lapses with >30-second-long frames) the Sony must be used with an external Intervalometer. They can cost anywhere from $100 to $400. I think it’s a great camera for both astrophoto stills and video. NOTE: I performed all Raw developing with Adobe Camera Raw v10.3. How evenly an image is illuminated is a common factor when testing lenses. Canon and Nikon both offered factory modified cameras at one time, notably the Canon 60Da and Nikon D810a. I have the A7S, A7RM2 and A7M3 and have been playing with the A7S since 2014, 2016 A7RM2 and 2018 A7M3 with Astro MW and other things. Yet frames taken with LENR on were the same 47 Mb size as normal uncompressed frames. In the meantime, Sony commands the full-frame mirrorless market. Custom Buttons  You’re right about the benefits being more in the shadows than the highlights though. I keep my A7RM2 vs upgrading to the A7RM3 for that reason BUT BUT LOVE REALLY LOVE the A7M3 for the sensor (ISO Invariant) and the 10 frames per second and many other likes!!! But this is a tough call. I shot with the Sony a7III on Single shot drive mode, on Continuous Low drive mode (with the camera controlling the shutter speed in both cases), and a set with the Sony on Bulb and the shutter speed set by an external Vello intervalometer. The compact a7III body weighs a measured 750 grams, vs. 900 grams each for the Nikon D750 and Canon 6D MkII. You would get more stars only by going to smaller pixels perhaps, but then there’d be more noise as well partly hiding the smallest stars. Most tests focus on its superb auto exposure and auto focus capabilities that rival much more costly cameras, including Sony’s own a7rIII and a9. I bought one and I'm truly enjoying it for night photography. Yes, that’s right Steve. On the a7iii the differences between iso 400 and iso 640 pushed to be equal exposure, the 640 image is cleaner even with a shorter shutter time due to the dual gain system ‘kicking in’ at iso 640. But I invite you to test your own images with various programs to see for yourself, and to not depend on second-hand reports like mine! Cheers! In this test, the Nikon did not perform as well as the Sony for ISO invariancy. Hi, Alan. I hope you found these latest tests of interest. Using the right lens adapter (I use one from Metabones), it is possible to use lenses with mounts made for Canon, Nikon, Sigma and others. That’s why using exactly same sensor, different make and model cameras may produce diff quality images.). When shooting deep-sky objects, particularly red nebulas, we like a camera to have a less aggressive infrared cutoff filter, to pick up as much of the deep red Hydrogen-Alpha emission line as possible. Stars are visible to the same limiting magnitude and close double stars are just as well resolved across all exposures. So even if you should only do a 12 second shot for no star trails with a 12mm f/4 for a big print you can increase the ISO or just leave at 800 and brighten in post. Live View was absolutely superb, though the outstanding Bright Monitoring function is as well-hidden as Sony could possibly make it. Taking a dark frame with LENR did not eliminate this, and it should, demonstrating again that for whatever reason in the a7III LENR is not as effective as it should be. Give me a Canon full-frame any day for prime-focus deep-sky shooting. The Nikon seems to discolor stars only when LENR is applied. Go figure! 留99, 留7s, 留7r + Zeiss 16-35/E35/50/85/135, A7Riii | A7ii infrared mod | Minolta ���7, A7RII Batis 85 f/1.8 // A5100 50 f/1.8 // A6000 18-105 f/4, A9 | A7Riii | Sony Pro | andrewwevers.com. It magnifies the Live View by 5.9x or 11.7x, allowing for precise manual focusing on a star. That’s why we do science! It shouldn’t. https://www.dropbox.com/s/5vhcblsvfyvvoqd/NoiseComparisons.zip?dl=0. Yes, this can all be done later in processing, but having the camera do the stacking can often be convenient, and great for beginners, as long as they understand what those functions do, or even that they exist! I don’t know if you’ve ever used the a7Rii to be able to comment; probably not or you would have in the arrticle. This has been so insightful for me as an amateur. The settings menu is still exceptionally long and deep, but functions have been categorized into useful groups and as a … Has anybody tested it yet? None have been tempting until the a7III came out. So you still need an external intervalometer for time-lapses with frames over 30s long. Only Slot 1 will work with the fastest UHS II cards that are needed for recording the highest quality 4K video. UPDATE: In April 2019 Sony issued a v3 Firmware update for the a7III which added an internal intervalometer. In January I embarked on a personal challenge to spend #100NightsUnderTheStars. Turn on LENR and it is possible to shoot three (with the 6D MkII) or four (with the 6D) Raw images in quick succession even with LENR turned on. These are from DPReview’s noise comparison test images. Sony mirrorless I ’ ve used the Rokinon 14mm f2.4 SP and the a7III will sell for less.
