The Nikon looks very clean, but the Sony also shows discoloration, green here, and an increase in noise. Filed Under: Reviews Tagged With: A7III, Alan Dyer, Astrophotography, sony, Sony A7III, star eater. I wanted to reach out to the community and see if anyone has great astrophotography settings they've used. One question though, I set Memory 1 to your landscape settings and Memory 2 to Action. The image with e-shutter and in Silent Mode is a tad sharper, but that could be just as much from variations in seeing conditions as from the lower vibration from using the electronic shutter. RED SENSITIVITY COMPARED – Three deep-sky exposures compare cameras for red sensitivity: a filter-modified Canon 5D MkII, a stock Canon 6D MkII, and the stock Sony A7III. This might be a contributing factor. 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. STAR TRAILS and AURORA With the Laowa 15mm lens and Sony A7III, for 155 exposures, all 20 seconds at f/2.8 and at ISO 800, and taken as part of a 360-frame time-lapse. I did this testing in preparation for the new third edition of my Nightscapes and Time-Lapse eBook, which will include information on Sony mirrorless cameras, as well as many, many other updates and additions! the lens cap on!) 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. In well-exposed images, I saw little difference in image quality. 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. An alternative would be an LCD screen that was touch sensitive. Your cameras are getting worse for astrophotography while Sony’s are getting better.Â. 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.Â, 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. UNCOMPRESSED vs. COMPRESSED – Here I compare any image degradation from using compressed vs. uncompressed Raws, and from employing Long Exposure Noise Reduction. Instead, you have to go to the Camera Settings 2 page, then select Still Image–Custom Key. It magnifies the Live View by 5.9x or 11.7x, allowing for precise manual focusing on a star. Camera Settings 1 > Peaking Setting. This is all with Raws developed with Adobe Camera Raw. I have now retired my Sony a6000 and added a new filly to the stables, a Sony a7III. The compressed images appear identical to the uncompressed files for noise and star content. 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. Still, this is a neck- and back-saving feature for astrophotography. (See other lenses that work.) This is from a thin metal mask in front of the sensor. 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. Sony A7iii - Essential Settings for a DSLR convert! MF Assist: On – a great feature that automatically zooms in when you move the focus ring in manual focus mode. An example is the Laowa 15mm f/2 I used for some of the testing. Keep in mind, these are vastly underexposed images. 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. Dunja Djudjic is a writer and photographer from Novi Sad, Serbia. The Sony showed poor deep-red sensitivity, though not unlike other cameras. The Canon 5D series also has this.Â, The dark frame kicks in and locks up the camera only after the series of “light frames” are taken. And star colors are not affected, though very small stars are sometimes green, an effect seen in other cameras due to de-Bayering artifacts. Both the Sony and Nikon use sensor and signal path designs that are “ISO invariant.” As a result, images shot underexposed at slower ISOs, then boosted in exposure later in processing look identical to properly exposed high-ISO images. (True 4K is actually 4096 x 2160 pixels.). But it is compatible with many external intervalometers and controllers. The Sony would perform better for noise under dark sky conditions, at high ISOs, rather than the moonlit scene above. Canon and Nikon both offered factory modified cameras at one time, notably the Canon 60Da and Nikon D810a. Sony for wedding photography Here’s my opinion. Reddit's most popular camera brand-specific subreddit! Very noticeable star trails so images really arent good for anything other than small posts like instagram. I trust you’ll find the review of value. 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. This does a fine job smoothing frame-to-frame flickering in time-lapses, something the Canon cannot do. Hey Guys, I just got my Sony A7III with the 24-105mm G lens. One battery can get you through a night of shooting, though performance will inevitably decline in winter, as with all cameras. My current gear list; Nikon D5300. Among Sony full-frame mirrorless bodies, a7RII, a7RIII, a7III and a9 can do continuous eye AF tracking. UNCOMPRESSED vs. COMPRESSED DEEP-SKY – A real-world deep-sky example shows the same comparison. AURORA VIDEO FRAME – This is a frame grab from a real-time 4K video of a “Steve” aurora. And neither are 4K. ISO Invariance  However, I’ve found these post-shoot darks rarely work well, as the dark frames are not at the same temperature as the light frames, and often add noise or dark holes. It’s unfair to blame just the hardware or the software. Note the size difference. Maybe a bit noisy (hard to tell as I had a CLS filter), but still interesting to look at ^, 24mm you're gonna wanna keep shutter speed at around 15 seconds to not get visible trails. The Canon 6D MkII has a fully functional touch screen which can be, quite literally, handy at night. This isn’t a huge detriment, as anyone who really wants to go after deep nebulosity must use a “filter-modified” camera anyway. 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. At 24 fps videos are full-frame with no cropping. Star Eater To the eye, the Sony and Nikon look very similar for noise levels, just as in the moonlit scene. Live View was absolutely superb, though the outstanding Bright Monitoring function is as well-hidden as Sony could possibly make it.Â. With DSLRs it is the raised mirror which often casts a shadow, produced a dark vignetted band along the bottom of the frame. As expected the filter-modified camera picks up much more red nebulosity. NIKON: I deducted points for real-time video of auroras – the D750 can do them but is pretty noisy with the high ISOs needed. They can cost anywhere from $100 to $400. Samyang 135mm f2.0 ED UMC. 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. That includes simple intervalometers like the Vello, the Syrp Genie Mini panning unit, and the Dynamic Perception and Rhino sliders, to name devices I use. Like the Nikon D750, the Sony’s screen tilts vertically up and down, great for use when on a telescope, or on any tripod when aimed up at the sky. Going to be very hard to get good astro at f4. When using a slow shutter speed with ND filter for waterfalls on a Sony mirrorless camera, like the Sony A7riii or A7iii, don’t forget these settings: Use a tripod; ND filter attached to lens, between a 6 stop and a 10 stop filter. 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? Nor the Sony, as it has no intervalometer at all. Features  Wow! Images are only slightly underexposed and boosted by +1 EV in Camera Raw. While the 6D MkII has HD video, it is incapable of any low-light video work. I know … people shoot dark frames separately for subtracting later in processing. He fell in love with photography in 2013 when he got a camera as a birthday present. 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. SONY WITH THE SYRP GENIE MINI – The Sony A7III worked well with the Syrp Genie Mini motion controller with the right shutter cable but only when placed in Continuous mode. Conclusion and Verdict. To reduce battery drain it is possible to turn off the EVF completely – I find I never use it at night – and to turn off the LCD display when shooting, though the latter is an option you have to activate to add to the Display button’s various modes.Â, The downside is that when shooting is underway you get no reassuring indication anything is happening, except for a brief LED flash when an image is written to a card. Â. I am very impressed! Its red sensitivity is not bad, but its lack of a light frame buffer results a less productive imaging cycle when using LENR on deep-sky shooting. Also, it's a digital camera, just play with the settings, you're not going to waste any film. Tokina 11-16mm f2.8 ATX PRO DX II. Adam owns a production company that specializes in corporate marketing and brand strategy. How evenly an image is illuminated is a common factor when testing lenses. Yet, just as many stars are recorded and are resolved, and at the lower ISOs/longer exposures more stars are visible because faint stars are not lost in the noise. • The A7III lacks any internal intervalometer or ability to add one via an app. With a full frame sensor and ISO 409600, is it the best low light camera out there? LUNAR CLOSE-UPS COMPARED – This trio compares closeups of the Moon taken with and without electronic front curtain shutter. the 500 rule is pretty bad for today's cameras. Introduction The Sony … A built-in intervalometer is not essential, since in time-lapse shooting we often use external controllers anyway. In testing the Sony A7III I ignored all the auto functions. But the Nikon did show more image artifacts in the “odd-numbered” ISOs of 640 and 500. The inset image at right in Photoshop shows the scene, the Milky Way above dark trees in my backyard! It is not clear if Sony’s compressed Raws are 12-bit vs. 14-bit for uncompressed files. Long exposures showed just as many stars as did short exposures. All cameras show an equal number of stars recorded. While these might add glows to long exposure images, if they could be designed not to do that (i.e. While you can look through and frame using the EVF as you would with a DSLR, you are looking at an electronic image from the sensor, not an optical image from the lens. The resulting values and graph show the Sony actually measured worse for noise than the Nikon at each high ISO speed, 3200 to 12800, though with both performing much better than the Canon. LENR also added a background level of fine noise. Fair enough. Shadow noise is similar in all images, with the ones taken with LENR on showing elimination of colored hot pixels, as they should. In particular, many stars look green, from the dominance of green-filtered photosites on Bayer-array sensors. 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. This is a blow-up of the lower corner of the frame, as indicated. It just needs to be better, Sony! Or rendered with little or no color at all. Now it’s time to get deep into those camera menus and show you how I setup my camera to shoot surf and ocean images. One battery can get you through a night of shooting, though performance will inevitably decline in winter, as with all cameras. Sony A7III Software. The Sony A7III’s screen is, but only to select an area for auto focus or zooming up an image in playback. I was shooting on a Canon 70D & Sigma 18-35 f1.8 and just switched to the Sony A7R III & Sony 16-35 f2.8GM for Astrophotography but unfortunately, I don’t find the combo sensible enough. At 30 fps, 4K videos are cropped with a 1.2x crop factor. SONY vs NIKON HIGH ISO under DARK SKIES – Noise levels appeared visually similar but the Sony showed more shadow details. You can find out more about Alan on Amazing Sky. I tested a Sony A7III purchased locally. I was using the wired Vello intervalometer. In Continuous mode, I think the effect is still there but maybe a little less. Raw Therapee offers a choice of de-Bayering, or “de-mosaic,” routines, and each produces different looking stars, and none look great! 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. 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. . Yet frames taken with LENR on were the same 47 Mb size as normal uncompressed frames. Those underexposed images were then boosted later in processing (in Adobe Camera Raw) by the required Exposure Value to equalize the image brightness. The cameras were on a Star Adventurer Mini tracker to keep stars pinpoints, though the ground blurred in the longer exposures. Based around an updated 24.2-megapixel back-illuminated full-frame sensor, the A7 III punches well above its weight with a rich feature including a 693 phase-detect autofocus system, 10 frames per second, internal 4k video, and silent operation. Adam Frimer is a Guinness World Record holder, producer, and DoP based in Tel-Aviv, Israel. It controls the Sony through the camera’s Multi USB port. The 2008-vintage 5D MkII had a 5-frame buffer!
