Thanks for the test. While most of them only offer an “electronic first curtain shutter” the A7s(II) and and A7rII even offer a completely silent, purely electronic shutter. The a7RII seems to have about a stop better high ISO performance than the a7II, which has about two stops better than the APSC cameras we have used. 3.) I set the camera for the mechanical shutter, with silent shutter off. I’ll test it. To get the highest scan rate, you need compressed raw and the fastest continuous mode. The sensor is not faster in uncompressed mode. The above photo was taken in silent shutter mode, which is … The Silent mode only work for single shots without flash. Just multiply 30 milliseconds x apsc sensor height (16mm) / full frame sensor height (24mm) = 20 milliseconds or 1/50. I’ve created a Category called a7RIII. You will recall that I set the shutter speed for 1/1000 second. I’m confused at how this works practically. A7RII shutter speed changing in Manual Started Nov 20, 2016 why in manual mode shutter speed is automatically changing when takes a photo. snapsy wrote: I suspect the Silent Shutter wont noticeably reduce image blur vs the EFCS. But if it does the extra noise from its 12-bit operation can be offset by bracketing the exposure even for cases where bracketing wouldn't otherwise be called for, to increase the SNR of the entire final image esp from the … Required fields are marked *. Image processing for in-camera histograms, Making the in-camera histogram closely represent the raw histogram, Leica 90/2 Apo-Summicron ASPH-M on GFX 50S. I’m guessing the A7rII is also capable of 1/30 readout but Sony didn’t bother to run the configure the sensor/ADC to utilize it. Noise is different. The effect on images may vary depending on the camera model and camera settings. The only confirmation that you have taken a photo is a momentary blackout through the viewfinder or on the back screen’s live view. There has been some debate online (and a lot of hot air) about whether you should be switching the e-front curtain shutter off on your Mirrorless camera. https://en.wikipedia.org/wiki/Focal-plane_shutter. It's fantastic for sneaking around public and private places, or shooting from a blind. I was pleasantly surprised to find that when the Sony a7iii claims to have a silent shutter, it’s really true. I’ve also added a widget called Category List to the right sidebar, below the Articles widget. Shutter Speed Range: 1/8000 - 30 sec: Bulb Mode: Yes: Exposure Compensation: +/- 5. 2.) 1/1000 second is one millisecond. But if we set the file format to compressed raw, and the shutter mode to continuous (C), things move a bit faster: That’s almost twice as fast, or about 1/30 second. Interesting results. I used C3. Press the MENU button → (Shooting) → Shutter/Silent → Shutter Type → Electronic Shutter. Thanks. Is it still reading out only 12 bits in compressed continuous? The following camera models have an added electronic sound that is always on. Sony responded to this in the A7RII with a brand new shutter mechanism. Restrictions when using the Silent Shooting mode. Is elettronic shutter in apsc mode faster? However, this post outlines a few of the many a7RII upgrades including 5-Axis Image Stabilization, best-in-class 399 point PDAF, dampened electronic front curtain shutter and silent shutter, improved high ISO image quality, more custom button settings, added bracketing modes, self-timer with bracketing and of course a few … Fine, except for distortion from either subject or camera blur. Is it still reading out only 12 bits in compressed continuous? The mechanical shutter is a rabbit, completing an exposure in 1/250 second (for shutter speeds faster than that, a slit moves across the sensor, but it takes the slit … It is in the a7RII and the D850. The mechanical shutter is a rabbit, completing an exposure in faster than 1/250 second (for shutter speeds much faster than that, a slit moves across the sensor, and we’ll see in this post how long it takes to make its journey). What’s wrong with conventional lens screening? Continuous is 14 bit when uncompressed RAW is used and 12 bit with compressed RAW. I put it at 3.4 divisions or the same number of milliseconds. -Yes, shutter is visible and appears fully 'closed', covering the entire sensor. I’m confused at how this works practically. The Sony A7R III's full-autofocus shutter lag (with the subject at a fixed distance) was 0.251 second in Single-area (center) AF-S mode versus 0.212 second for the Mark II with the same lens. I guess that the “compressed continuous” mode gives 12bit files, instead of the 13bits of “compressed_single” .. no ?. After all – it’s reading a full frame in 1/30 second, it should be able to read a 16:9 crop at 24fps with no issue – probably even 30fps although I’d accept if Sony had a mild crop at 30 like they do with A6300/A6500/A9. What is the bit depth of “uncompressed continuous” ?. This is the first post in a series on the Sony alpha 7 Mark III, aka the a7RIII. Photography wins -- most of the time. The width of the stripe is one division, or one millisecond. That’s about 1/250 of a second, which is about average for mechanical shutters these days. What is Silent Shooting? What is the bitdepth of “uncompressed continuous” ?. Sure. Just like with a mechanical focal plane shutter, speeds faster than the scanning time of the shutter are achieved by having a (virtual or real) slit that traverses the focal plane. The speed is not constant; if it were the diagonal green band would have straight edges. I set EFCS to on and set the file format to uncompressed raw, with the camera on manual exposure, the shutter mode single shot, and the shutter speed at 1/1000 second – that’s one msec. The fully electronic shutter takes longer to do its job. Just like with the mechanical shutter, which doesn’t traverse the focal plane in 1/500 second, either. Spectral sensitivity is different, if you can believe the compromise matrices in the EXIF data. Sorry, but don’t have access to Olympus gear. Thank you. If it scans at the same speed in each mode, then it should take around 1/50 second to scan the shorter height of an apsc crop zone. Will be nice if you will had the chance also for testing Olympus E-M1 II electronic shutter. The a7RIII has a silent shutter mode. The shutter accelerates as it moves across the sensor. The results were impressive. Copyright Office. Photography meets digital computer technology. I set up an analog oscilloscope with an input from a function generator. 4.) But if we set the file format to compressed raw, and the shutter mode to continuous (C), things move a bit faster: That’s almost twice as … I’ll test it. I’ve received some complaints that it’s hard to navigate in this blog, what with its couple of thousand posts and many multi-part series. Or is everything shot at 1/30th of a second. It’s the opposite. I’m trying something new. The a7rII now has both a silent mode as well as an electronic first curtain shutter mode, which cuts the vibrations of the shutter … The premium for the a7RII is worth it to some, but it would not be worth it to everyone. Other camera models . The only difference was that the A7RII was set to silent shooting mode, and therefore didn’t suffer from the notorious shutter shock vibration of the A7R, which is something of a problem for fast exposures and when using telephoto lenses. The A7rII is literally a flagship for Sony as it encompasses all the new technologies Sony has been working on the past few years, especially with the 5 axis stabilization combined with the world premier full frame back-lit sensor. The full frame sensor means the camera isn’t a budget model. It does not appear to me to be the same sensor. “But if we set the file format to compressed raw, and the shutter mode to continuous (C), things move a bit faster…”. If we project where the trailing edge of the green band intersects the top and the bottom of the frame onto the top and bottom of the oscilloscope graticule, and the horizontal distance in divisions between those dots will give us the shutter travel time. Read this: https://en.wikipedia.org/wiki/Focal-plane_shutter. that’s twice faster than mark ii, is this even possible? A slow shutter speed/long exposure has uses beyond just taking normal landscapes after sunset. Thanks again for all your tests – they help alot! I read this article and had hoped that using uncompressed and continuous mode might let me shoot at a higher shutter speed and still avoid banding with dimmed LED lights. I would expect that it would be in the III as well. As the shutter speeds get higher, the slit gets narrower. ADC characteristics are different. Shutter Count on a Sony a7RII Frogfish wrote : I'm not sure any amount is 'too many' as it depends on the condition of the camera and of course you can easily change the shutter assembly. Can you set 1/500 of a second on silent shutter? To change your shutter speed in MANUAL mode, turn the dial from AUTO all the way over to ‘M. http://blog.kasson.com/the-last-word/how-fast-is-the-sony-a9-electronic-shutter/. registering faces using the Face Registration feature. And on the topic of the Silent Shutter setting, yes there are some compromises such as a restriction … You can't turn off the shutter sound because these models are only equipped with a mechanical shutter. Silent shutter only works when you’re in one of these settings. I’ve put together a roundup of, registered with the U.S. I found a Sony A7rii for sale locally for only $1700 including a 28-70mm Sony lens. Sony A7RII with 90mm Macro G @ ISO 2000 Shutter Mechanism. To find out how much slower, we’ll have to change the scope’s time base. Silent Shooting is available … Thankfully, Sony addressed this issue on the A7R II, so shutter shock is no longer a … I set it to 10 milliseconds per division, and made another exposure: I put the scan time at 7 divisions or 70 milliseconds. This can obviously prove useful in sensitive situations, but it is not without issue. Both curtains accelerate at about the same rate, so that the exposure — the horizontal width of the green stripe — is about the same from the bottom to the top of the image. To get the highest frame rate, you need compressed raw and the fastest continuous mode. In s35 mode, electronic shutter is faster? Looking at this picture might be easier. There’s a drop-down menu there that you should be able to use to get to all the posts in this series. The A7II has been released just a year after the A7, same for the A7r/ A7rII and A7s/A7sII. Until the … When running silent, the mechanical shutter is open and the sensor does all the work. Unlike my previous camera the Canon 5D Mark III, which has a silent mode that is quiet, the Sony is actually silent. Curious, any test update on the A7r iii readout speed in APSC mode? 5fps , with little lag with mechanical shutter (with blackout) A7RIII (with blackout) 10 fps with little lag with mechanical/silent shutter; up to 8 fps without lag with mechanical/silent shutter; A7RII (with blackout) 5 fps with little lag with mechanical shutter; 2.5 fps with no lag with mechanical shutter; no continuous drive with silent shutter Now, let’s leave the scope set up the same way, switch the camera to silent shutter, and make another picture: The electronic shutter travels in the same direction as the mechanical one, from the top of the image to the bottom, or the bottom of the camera to the top. All full frame E-mount cameras (except for the A7r) feature an electronic shutter in addition to the mechanical shutter. It looks like a camera icon with the number 2 to the right of it and the background is purple. Would a car driving down the street look blurred? When running silent, the mechanical shutter is on vacation: the sensor does all the work. Robert Treman park in Ithaca, NY with Sony A7r3 and 16-35mm F/4 and 10 stop ND filter In the photography class I teach, I’ve been asked several times the purpose of ND filters. You can see that the electronic shutter is much slower. what?? Would be great to know, as its a key feature for me in thinking about upgrading (I work on film sets where I need to shoot silent mode all the time). The Sony alpha 7 Mark II (aka a7RII) has a silent shutter mode. The mechanical shutter on the a7RIII, like the shutters on all the a7 series, travels from the top of the image to the bottom. But there’s also bunch of new setting you … For the most part, they can be expected to share the same limitations. All of the current generation full frame cameras – Sony A9, Sony A7rii, Sony A7iii, Nikon Z6, Nikon Z7, and Canon R are all equipped with silent shutter capabilities. Double performance WAS Sony’s claim when the camera was announced. The a7RIV takes about 1/15 second to do the scan, so we’re going backwards here, thanks to the higher pixel count of the […], Your email address will not be published. Shutter. Seems a little bit extravagant…. Silent Shutter: Another lesson I learned the hard way is that the Silent Shutter should be turned off. This would cause issues with longer lenses, causing the shutter to shake the camera, sometimes causing an image to be out of focus, even when using a tripod and remote control. Maybe that’s where they made their gains. Unfortunately, Sony seems to have only done this for certain use cases – for others (such as video) there is no change from the R2 as far as I can tell – double performance should have allowed for full-sensor-width video sampling with no pixel skipping. It is in the a7RII, and probably is in the a7RIII. Then look at this example of focal plane shutter distortion: https://en.wikipedia.org/wiki/Focal-plane_shutter#/media/File:Bundesarchiv_Bild_183-1991-1209-503,_Autorennen_im_Grunewald,_Berlin.jpg. I put a generic RRS plate on the camera and clipped it into an Arca Swiss C1 head on a Gitzo tripod. So what do images look like with silent shutter? I mounted a Sony 90 mm f/2.8 lens on the camera. That’s about 1/15 of a second, or about the same speed as the a7RII silent shutter.
