The A7 III is a fairly complex camera with tons of features, so I’m going to share exactly how I set my camera up for maximum efficiency on a portrait shoot. Adam Frimer is a Guinness World Record holder, producer, and DoP based in Tel-Aviv, Israel. I hope you found these latest tests of interest. Very noticeable star trails so images really arent good for anything other than small posts like instagram. Again, here I show only the Sony and Nikon, the two “ISO invariant” cameras. The Canon is more neutral and natural. STAR EATER DEEP-SKY #1 – Tracked deep-sky images through a telescope using 4-minute exposures show the Sony A7III recording an equal number of faint stars as the Canon 6D MkII. The Sony A7III uses a sensor that is “Backside Illuminated,” a feature that promises to improve low-light performance and reduce noise.Â, I saw no great benefit from the BSI sensor. As expected the filter-modified camera picks up much more red nebulosity. I wanted to reach out to the community and see if anyone has great astrophotography settings they've used. 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! But the Nikon did show more image artifacts in the “odd-numbered” ISOs of 640 and 500. I trust you’ll find the review of value. STAR EATER DEEP-SKY #2 – Another example with 4-minute exposures again demonstrates no problems recording faint stars. UNCOMPRESSED vs. COMPRESSED – Here I compare any image degradation from using compressed vs. uncompressed Raws, and from employing Long Exposure Noise Reduction. The higher noise of the Canon is visually obvious, but I’d say the Sony A7III and Nikon D750 are pretty equal visually for noise, despite the numbers. I usually leave Minimum ISO at 100, while … It shouldn’t. For another example of using the Sony A7III for recording real-time video of the night sky see this example of the Space Station crossing the sky. Lenses developed natively for mirrorless models can be smaller and lighter. Sensor Illumination Uniformity No noise reduction was applied in processing. Wow! Nevertheless, for the demands of nightscape and deep-sky shooting and processing, I suggest shooting Uncompressed Raws. COMPARING NOISE – The Sony A7III exhibited noise levels similar to the Nikon D750 at high ISOs, with the Sony and Nikon each about a stop better for noise than the Canon 6D MkII. The disadvantage is that full-time live view draws more power, with mirrorless cameras notorious for being battery hungry. This feature is little known and utilized, and only Canon full-frame cameras offer it. I want to switch to Sony A7 III. These have had exposure and contrast increased to exaggerate the differences. Seeing is believing and I am confident that when the word gets around of how TRULY amazing this Gmaster 24mm f1.4 is, it will be called the holy grail of lenses for astrophotography. This is most noticeable – indeed usually only noticeable – when shooting deep-sky targets though telescopes. The recently released (late 2018) Sony 24mm f/1.4 GM lens is another top-quality lens for astrophotography from Sony. 20-sec., f/2.8, ISO 10,000 Shoot RAW I always shoot astro in RAW as there really isn’t any good reason to shoot them in JPEG considering you will always need to do some post processing for the best final images. This is wonderful for taking a set of noise-reduced deep-sky images for later stacking. It just needs to be better, Sony! I used the Metabones Canon-to-Sony adapter when attaching the Sony to my telescopes using my existing Canon telescope adapters. I have now retired my Sony a6000 and added a new filly to the stables, a Sony a7III. In well-exposed images, I saw little difference in image quality. A lot of people buy a nice camera and then use it with all the default Thus my Good rating for nightscapes but Fair rating for time-lapses. This is good news, as astrophotography requires fast, high-quality lenses, and the Sony allows more choices. As its name implies, a mirrorless camera lacks the reflex mirror of a digital single lens reflex camera that, in a DSLR, provides the light path for framing the scene though the optical viewfinder. The Nikon seems to discolor stars only when LENR is applied. Why would that be? An alternative would be an LCD screen that was touch sensitive. Press question mark to learn the rest of the keyboard shortcuts, https://www.youtube.com/watch?v=en4eeK33UoE. Again, the differences are in images vastly underexposed. Most DSLRs do not offer this, but the Sony’s option of an electronic front curtain shutter and the additional Silent Shooting mode completely eliminates vibration, useful for some high-magnification shooting through telephotos and telescopes. The Sony doesn’t do quite as well as the Canon 6D MkII. Dunja Djudjic is a writer and photographer from Novi Sad, Serbia. In testing the Sony A7III I ignored all the auto functions. An example is the Laowa 15mm f/2 I used for some of the testing. But Live Focus is where the A7III really stands out. 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. the lens cap on!) The compact A7III body weighs a measured 750 grams, vs. 900 grams each for the Nikon D750 and Canon 6D MkII. The Sony would perform better in an ISO Invariancy “face-off” if its ISOs were kept above 640, to keep all the images within the Sony’s upper ISO range of its dual-gain sensor design, with two ranges (100 to 400, and 640 on up). Contrary to expectations, the Sony did not show any great loss in image quality as it crossed the ISO 640 boundary into its lower ISO range. Certainly not as good as the Canon rendered with Camera Raw. Also missing, and present on most new Canons, are Multiple Exposure modes for in-camera stacking of exposures in a Brighten mode (for star trails) or Averaging mode (for noise smoothing).Â. In particular, many stars look green, from the dominance of green-filtered photosites on Bayer-array sensors. NOISE AT ISO 3200 – At ISO 3200, a common nightscape ISO speed, all three cameras performed well in this moonlit scene. These were then boosted in Adobe Camera Raw by 2 and 4 stops in Exposure Value (EV) to compensate. Otherwise, I agree with /u/RathEmpire's settings, I think you can probably go to 3200 or 6400iso if this is too dark. At F4, you should push the shutter speed to 20s. You can push it to maybe 20 seconds if you won't be looking at it in a large size (ie. https://www.youtube.com/watch?v=en4eeK33UoE This should help you! Then we have the RAW file type with two options: Compressed or Uncompressed RAW. For those who think this is normal for LENR use, the Nikon D750 shows nothing like this – frames taken with LENR on are free of all hot pixels and do not show more shot or read noise, nor deterioration of shadow detail from lower bit depths. We are an unofficial community of users of the Sony Alpha brand and related gear: Sony E Mount, Sony A Mount, legacy Minolta cameras, RX cameras, lenses, flashes, photoshare, and discussion.

How evenly an image is illuminated is a common factor when testing lenses. Here are some other Sony A7III features I found of value for astrophotography, and for operating the camera at night. STAR EATING vs DRIVE MODE – This series shows star sharpness in images taken in Single and Continuous drive modes, and in Externally Timed exposures. The correct exposure for the scene was 30 seconds at ISO 6400 and f/2. Hey Guys, I just got my Sony A7III with the 24-105mm G lens. Canon and Nikon both offered factory modified cameras at one time, notably the Canon 60Da and Nikon D810a. In the menu options that appear you can now scroll to one called Bright Monitoring. 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 camera itself can be used in a number of different settings such as dusk and dawn, and … • The A7III lacks any internal intervalometer or ability to add one via an app. STAR EATER SERIES at 200% – This series of tracked images (shown here blown up 200%) goes from 2 seconds to 2 minutes, with decreasing ISO speed to equalize the exposure value across the series. Samyang 135mm f2.0 ED UMC. (True 4K is actually 4096 x 2160 pixels.). All were taken through a 130mm refractor telescope at f/12 using a Barlow lens. As photographers age, this becomes a more essential feature! 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. Hacking Photography - one Picture at a time, I put the new Sony A7III mirrorless camera through its paces for the features and functions we need to shoot the night sky. SONY vs. NIKON – Comparing just the two ISO-invariant cameras, the Sony and the Nikon, on another night, shows a similar performance difference when boosting underexposed slow-ISO images later in Camera Raw. Or rendered with little or no color at all. While these might add glows to long exposure images, if they could be designed not to do that (i.e. The reds have been boosted in processing. Overall Recommendations UNCOMPRESSED vs. COMPRESSED at -4EV – The same scene but now underexposed by 4 stops and boosted by +4 EV later shows greater differences. In the meantime, Sony commands the full-frame mirrorless market. This makes it so easy to frame nightscapes and deep-sky fields. This was true whether I was shooting compressed or uncompressed Raws, with or without Long Exposure Noise Reduction. Note the size difference. INTERVALOMETER – For time-lapses, the Sony must be used with an external intervalometer like this Vello unit. To the eye, the Sony and Nikon look very similar for noise levels, just as in the moonlit scene. Since publishing the first results a number of people commented with suggestions for further testing, to check claims that: For the additional tests, I shot all images within a 3-hour span on the night of June 5/6, using the Sony A7III, Nikon D750, and Canon 6D MkII, with the respective lenses: the Laowa 15mm lens at f/2, the Sigma 14mm Art at f/2, and the Rokinon 14mm SP at f/2.5. Nor is there any amp glow anywhere along the frame edges. Whether you are pursuing DSLR telescope astrophotography or simple using an astrophotography tripod , there are certain tricks and techniques you must follow. Between 3.2s and 4s a very slight one-pixel-level softening does kick in, reducing noise and very slightly blurring stars. Camera Settings 1 > Peaking Setting. SONY WITH AND WITHOUT LENR – These are 4-minute exposures of dark frames (i.e. An issue that, to me, has a more serious effect on star quality is the propensity of the Sony, and to some extent the Nikon, to render tiny stars as brightly colored points, unrealistically so. With DSLRs it is the raised mirror which often casts a shadow, produced a dark vignetted band along the bottom of the frame. Even if you could get a mirrorless camera to focus without a lens adapter to add the extra spacing, the image quality across the field might be compromised on many telescopes. I saw none of the extreme effects reported by others with other Sonys, where masses of faint stars disappeared or turned into multi-colored blotches. That’s worth a check, too. AURORA VIDEO FRAME – This is a frame grab from a real-time 4K video of a “Steve” aurora. 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. Sony for wedding photography Here’s my opinion. NOISE AT ISO 6400 – At ISO 6400, the Canon begins to show excessive noise, about a stop worse than the Nikon and Sony. It’s a well-rounded camera that holds almost nothing back in terms of raw power and capability for an ever-changing digital photography market. The Sony A7III offers a choice of shooting Uncompressed or Compressed Raw files. It magnifies the Live View by 5.9x or 11.7x, allowing for precise manual focusing on a star. If you have recently come across from a DSLR to the sony mirrorless system, you might know how the camera works...but there are a few new settings that are worth learning about. He is an associate editor of SkyNews, Canada’s magazine of stargazing, and a contributing editor to Sky & Telescope magazine. This Sony lens review intends to look for what can be classed at the best lens for Sony A7iii astrophotography. Indeed, at slower ISOs and longer exposures, more stars are visible. I would assume not, but not having an a7s (either Mark I or II) to test I can’t say for sure. Only being f/4 is gonna limit you. Noise Plus, the Sony was far better than the Canon 6D MkII’s “ISO variant” sensor. New comments cannot be posted and votes cannot be cast. 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. Posting to instagram). SkyWatcher Star Adventurer. Long exposures showed just as many stars as did short exposures. April 12, 2020. While the 6D MkII has HD video, it is incapable of any low-light video work. It intrudes into the light path ever so slightly. Standard functions such as ISO and Drive Mode are easy to get at on the thumb wheel, unlike the Nikon D750 where I am forever hunting for the ISO or Focus Zoom buttons, or the Canon 6D MkII which successfully hides the Focus Zoom and Playback buttons at night. Due to limitations set by Sony, controlling one of their cameras with an external controller can be problematic.Â, Devices that trigger only the shutter should be fine. 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. SONY LIVE VIEW – The Sony A7III’s excellent Live View screen display. I wanted to reach out to the community and see if anyone has great astrophotography settings they've used. Effectiveness of Long Exposure Noise Reduction (LENR), Quality of Raw files, such as sharpness of stars, Brightness of Live View for framing and focusing. The Nikon had the Sigma 14mm Art lens; the Canon and Sony used the same Rokinon 14mm SP lens. I love it! • It lacks the “light-frame” buffer offered by full-frame Canons that allows shooting several frames in quick succession even with LENR turned on. Lots of menu options to go through, with different functions thrown under random menus. LENR also added a background level of fine noise. See what that gets you. I rate the Sony excellent for nightscape imaging and for real-time aurora videos. As such, I would have expected a more uniformly illuminated sensor. STAR EATER SERIES at 400% – This is the same series as above but now blown up 400% to better reveal the very subtle change in pixel-level sharpness as exposure lengthened from 3.2 to 4 seconds. I found the A7III would use up about about 40% of the battery capacity in a typical 400-frame time-lapse on mild spring nights, with 30-second exposures. But astrophotography, which often requires extreme contrast boosts, reveals non-uniform illumination of the sensor itself, regardless of the optics, originating from hardware elements in front of the sensor casting shadows onto the sensor. Shooting typical 400-frame time-lapses used about 40% of the battery capacity, similar to the other DSLRs.Â.
