At high shutter speeds, there is little blur because the camera doesn’t have much time to move while the shutter is open. The lens: the Leica 280mm f/4 Apo-Telyt-R. At low speeds, most of the vibrations have damped down during most of the time the shutter is open, so there’s not much blur. How to Set Up Silent Shutter Mode on Your Sony a6500. Maybe the sun and moon and stars aligned so that there was vibration cancellation. I thought you were tough. How does the GFX100 compare to the GFX50? A data point on Leicas and shutter shock. I exported crops of the slanted edge target as TIFFs, and computed MTF50, which is a good proxy for sharpness, using Imatest. Be among the first to get the latest Sony news in your inbox. I have not tested the M10, but I had an M240 for several years, and it had a lot of shutter shock and no EFCS. Photography meets digital computer technology. The only part that might be a little confusing is navigating the camera’s menu system. WHen the a7RII came out, shutter shock was no longer much of an issue not because there was a lot less of it with the mechanical shutter, but because it had EFCS. With the a7RII, i used the mechanical shutter for one set of images, the electronic first-curtain shutter (EFCS)  for another, and the all-electronic — silent — shutter for a third. Silent Shooting is a camera feature that allows you to shoot images without the sound created by the mechanical shutter. -In silent shooting it exposes, but it's a very black frame.-> I tried turning silent shooting off and taking a shot and got "camera error, cycle power please", which remained even after the camera had been switched off. Specifically, the silent shooting option is only available when shooting still images in the P, A, S, or M shooting modes. IBIS stiffness when not engaged? Jim – on the A7RIV, does silent shooting/silent shutter reduce bit depth in single shot mode or does it remain at 14 bits? The effect on images may vary depending on the camera model and camera settings. I don’t normally test it these days, and only did so in the present instance because someone claimed that the shutter shock of the a7RIV was much less than that of the a7RIII. Even if [Silent Shooting] is set to [On], it will not be completely silent. The bad news? In the next picture, which is the same graph except the data is from the a7RIII exposures, you’ll see a situation where that isn’t true at all. In the United States and Canada, artificial light has a frequency of 60hz. Excellent stuff, Jim. Re EFCS vs Silent performance: I don’t think a 1 bit difference in the encoding at these contrast ratios should affect MTF results obtained through the slanted edge method. Silent shooting with the Sony A7R III is impressively, well, silent. Even if a quantization error were introduced it would look like additional noise in the Edge Spread Function, which would show up as modulation of the results: but here the average is consistently lower. There’s a drop-down menu there that you can use to get to all the posts in this series; just look for “A7RIV”. Amazing!!! The larger pixel size of the a7RIII will smooth things out, but it shouldn’t happen to that extent. Sadly I have an A7r and don’t feel inclined to fork out 3k for the Mk2 version at this point. Or is it simply muffling the transmission of the shock to the photographer’s ears? Sony a7rII Shutter Button Soft? Just like the Nikon Z6 and Z7 and Canon EOS R. But there are specific differences which might affect your decision about which camera best suits your needs. I actually thought the XH1 has sharper images than the XPro2/XT2 due to the damped shutter but it would be interesting to see if your advanced measurements support that hypothesis that cameras with spring balanced shutters are superior to the A7R3. The following camera models have an added electronic sound that is always on. This is a harder test for the mechanical shutter than yesterday’s, since using the lens collar as the tripod mounting point allows the camera to move more than mounting the camera body directly to the tripod. The tension of each of these five springs is different because the impact on each of the 5 points is different when the shutter is pressed. Some lucky coincidence of adapter/lens/whatever having a suitable resonance frequency (on this particular implementation of the mount), so that all the energy of vibrations goes into a mode which does not affect the quality of the photo? By Louis Ferreira | Published: March 8, 2018. The second was an unplanned side effect of a well-meaning decision. But there are unfortunately some limitations you should be aware of. For A7R4, ECFS takes care of a lot of shutter stock but if you have a static object, a pure Electronic Shutter is sharper than ECFS. A7RII - Banding issues in silent shutter mode: We had some school activity this weekend. First, I’ll drag you through the protocol. In fact, it works so well that going all the way to silent shutter mode doesn’t bring any significant improvement on single shots, although it almost certainly would on a series of exposures made in a short period. The blue curve is the a7R, and the red the a7RII with the mechanical shutter engaged. But hey, there is no sun there so let them enjoy the camera as first :)     https://en.wikipedia.org/wiki/Tuned_mass_damper So I took some pictures using RAW, uncompressed, silent shutter mode and no flash. With Fuji, the sensor has IBIS but in the GFX100 and X-H1: Looks like the a7RII mechanical shutter is a bit better than the a7R one. This can obviously prove useful in sensitive situations, but it is not without issue. Somewhere, I thought I read that you have used CameraWest before and if so, that gets you access to the M10 cameras. Here’s an analysis of one of the horizontal edges in the target with the a7RIV shutter set to mechanical, electronic first curtain (EFCS) and fully electronic (what Sony calls Silent Shooting). Unfortunately, in many cases, the shot-to-shot scatter due to autofocus errors was at least as large as the effect I was trying to measure, making it hard to make sense of the results. Just looking at this post though, it suggests: For A7R3, ECFS is great and has no issues. Unless the motor is suspended with the shutter, any spring system isn’t going to help with that. Fortunately, there was a workaround: turn off live view before tripping the shutter. So far everything is working as expected. First, I’ll drag you through the protocol. With EFCS, there’s less vibration because the camera doesn’t have to wind and release the shutter just before the exposure. Camera Labs gives us our first look at how well the Sony a7III electronic shutter works and it’s not much better than other cameras so the Sony a7III electronic shutter should be reserved for subjects not in motion. Using a remote release and A exposure mode, I made 16 exposures about 1 second apart at each setting with the light adjusted to give me shutter speeds of. With electronic shutter, there’s the lease vibration of all because no part of the shutter assembly moves either before, durning, or after the shutter is released. And I don’t usually — with one exception that I can think of when I thought I had a bad copy of the CO 60/4 macro and rented another copy from Roger at LensRentals — rent or borrow equipment, because I don’t like to feel rushed when I’m testing gear. Not much difference between silent shutter and EFCS. The filter: Heliopan 77mm variable neutral density. Crop, export as TIFFs, analyze for horizontal edge (that’s the edge perpendicular to the way the shutter travels) for the landscape shots, and vertical edge (that’s the edge perpendicular to the way the shutter travels)for the portrait shots. What ‘s the difference in terms of mechanical parts that move between the two modes? Granted it is used, but is that normal? Sony a7III: Mechanical Shutter vs Silent, Interview, Time-Lapse, Rolling Shutter and More. Making your Sony a7iii shoot silently isn’t available in every shooting mode, and not every feature is available when you turn the silent shooting on (more on that below). I processed all the files in Lightroom, with white balance set to flash, sharpening and noise reduction turned off, and all other settings at default. Damn lucky guys those brits! Required fields are marked *. Bryn, Thanks Jim! Unfortunately mounting a big, heavy lens like the 280/4 to the front of the camera unsupported is a recipe for damaging the lens mount. I went over the data several times, and double checked the EXIF information to make sure the cameras were set up the way I thought they were, and reran Imatest on another horizontal edge, but I didn’t find anything untoward. 0" 921. Even if [ Silent Shooting] is set to [On] , the operating sound of the aperture and focus will sound. “ The shutter unit is suspended with five springs so they act as a shock absorber when the shutter is pressed. Does an audibly quiet shutter translate into less shutter shock? That EFCS line appears too good to be true, but I double-checked the data. Photography meets digital computer technology. This contaminated the results, especially those at low shutter speeds. Cheers, […] data in yesterday’s post was pretty noisy, but it seemed to indicate that somehow the silent shutter mode on the Sony alpha 7 […], Your email address will not be published. When running silent, the mechanical shutter is on vacation: the sensor does all the work. Sony a7R II Silent Shooting was possible because data streams off the a7R II Back-Illuminated Sensor 3.5 times faster than previous Sony sensors. That’s 100 milliseconds, or 1/10 second.
