    Thanks, Bob - VERY INFORMATIVE as usual. I don't know where you find the time to keep these useful videos coming. Bottom line, YOUR time creating and sharing these teaching videos ultimately saves OUR time (multiplied by the number of viewers) digging and learning. Much appreciated.

    Hi Rob, As I delve deeper into understanding my E-M10ii , the mechanical vs electronic shutter subject had been difficult for me to understand. After viewing your tutorial I now have a much better appreciation of how they work and when best to apply either of them. Finding your TH-cam channel has been a real treat and is my go-to source for information regarding my camera & photography issues. Appreciate your work.

    That's why I appreciate your videos so much. You also explain how the camera works which enables me to understand my camera and with that what I have to do
    to achieve better pictures.
    I have allways been looking for something like that and now I am very grateful.

    Another superb tutorial Rob, so well presented and explained.
    I'm more engineer than photographer and love to know how things work.
    There are not many TH-cam channels that explain in simple terms what exactly goes on behind the buttons and timers, so I thank you and I hope you will continue making them.
    As an E-M1 mk2 user, I look forward to you explaining some of those camera's awesome features.
    Thanks Rob, from Wales.

    Hi Rob, great video as always but 1 part of it really confuses me. At about 15 mins I think you infer the curtain speed is about 1/320 sec and faster shutter speeds work by effectively reducing the aperture using a small gap between the upwards moving upper and lower curtains - does this mean that for freezing motion there's no benefit to going faster than 1/320 secs? Or have I misunderstood?

    • @RobTrek
      @RobTrek  5 ปีที่แล้ว +1

      Thanks. That is a great question! Not one I can answer right now. Fast action is definitely frozen at 1/8000th and not 1/320th. If the shutter is not moving faster than 1/320th as I implied in this video, then how is this possible without rolling shutter effect? I'm honestly having a little trouble reconciling this in my brain. It's very possible I am dead wrong in this video. I will research this more and try to answer this question asap. I am already losing sleep over this!

    • @nemethmik
      @nemethmik 4 ปีที่แล้ว

      @@RobTrek Your video is perfectly fine. 1/320 second rolling shutter is visible even in mechanical shutters, too, on the image between the top and the bottom stripes. However, this is way much better than the 1/15 - 1/30 second rolling shutter skew in electronic shutter. The Sony A9 has 1/160 second shutter rate, so is half as good as mechanical shutter.

  • @rebbel67
    @rebbel67 6 ปีที่แล้ว +2

    Thanks a lot, Rob, that was the clearest explanation of how shutters work I've seen to date.
    Very helpful!
    If I may: when a camera (E-M10) reaches its maximum shutter count, will it simply stop working?
    If so, can it be fixed/replaced, and would the cost weigh up to buying a new camera?
    Thanks again.

    • @RobTrek
      @RobTrek  6 ปีที่แล้ว +3

      I've never heard of any camera deliberately stop working based on a shutter count. If the shutter begins to wear or malfunction due to age, it's best to replace because other components that can fail won't be too far behind!

    Great explanation and much appreciated. When buying a used camera people are always concerned about shutter count. Obviously this must only be relevant to the mechanical shutter or does the firmware also count the electronic clicks? Also it may sound ridiculous but because I use a lot of exposure bracketing in A-mode I prefer the electronic shutter to "save" the mechanical and keep the count down.

    • @RobTrek
      @RobTrek  5 ปีที่แล้ว

      Electronic shutter should extend the life of the mechanical. Shutter counts vary by camera. My em10 counts electronic shutters, my em1 does not!

    Thank you for very specific and precise information on the issue of shutter modes. I have one question that I cannot find an answer to however much I search the forums and I believe a photographer of your knowledge may have clue about it. I have the Olympus omd em10 mark iii and the electronic shutter is only available in a specific mode called "the silent" mode and I can't seem to change the mode the camera works in this mode (say A, P or M mode)That is an issue I can live with but my real question is why the "intervalometer" options are all disabled when using electronic shutter. It is even so in mark ii and I cannot find any logical explanation other than the theory of "planned obsolescence". Or is there anything I am missing?

    • @RobTrek
      @RobTrek  4 ปีที่แล้ว

      I can't explain why, but they disabled the silent shutter in the em10-iii for all but AP modes. I can only guess on the intervalometer, but maybe to keep the sensor from staying on constantly for an extended period of time to prevent over heating?

    Where do I find 'Shutter Modes'? I have just updated the firmware to version 1.3, and I can only find mechanical and electronic shutter settings on the Control Panel, second column from the left, second from the bottom. This deals with single shot and burst modes with various shutter settings. Some of these are called 'silent'. About the menu in general, the nearest menu structure to this I have on the Olympus SP-570UZ bridge camera from 2008. Admittedly, the E-M10 II has not as many mutual lockouts as the earlier bridge camera.

    The new Sony A1 you can use flash with the electronic shutter. It's the only camera I know of that can do that. There was a flash setup that does work with cellphones I saw on fstoppers channel. I think these flashes stay on longer but you might get blur. I think its working the same way as the light on your cellphone but these are studio lights.

    • @RobTrek
      @RobTrek  3 ปีที่แล้ว

      That is cool. I read up to 1/200th in electronic shutter. The Olympus EM1ii & iii can do up to 1/50th. If they make flashes for cameras like these cell phone versions, I'd assume we could get even faster "sync" times - short of continuous lighting, LOL!

      I don't own the em5.ii, but the manual says you can program a function button to toggle between continuous and self timer. You could also program a myset with the self time selected, the program the myset to a function button. Hope that helps. :)

    Rob - an interesting video, but I think you don't have the anti-shock explanation 100% correct. Firstly, there is a difference between the older Olympus cameras with 0s anti-shock (E-P5, E-M1, E-M10) and the later cameras with that feature (E-M5ii, E-M1ii, Pen-F etc). Your explanation only applies to the older cameras. The newer cameras move one only curtain when you set anti-shock=0s and there is no short delay before exposure as with the older cameras. Secondly, for anti-shock settings of 1/8s and longer, the delay happens in a different place in the sequence and EFCS (Electronic First Curtain Shutter) is not used at all (whereas it's essential for 0s anti-shock). Hope this comment helps.

      Hi. I updated the title to say e-m10-ii. I used high speed fps to record the shutter action on my e-m10ii, and I see the mechanical first curtain shutter close, then open in anti shock. When anti-shock is set to 1/8 or longer, the mechanical first curtain closes, then opens immediately, then the second curtain rises after the set time. My PL8 has the same action. On my PenF and e-m1ii, in anti-shock mode, there is no mechanical first curtain shutter, regardless of the anti-shock delay setting - as you have pointed out, it's EFCS only. I'm a little confused on the second point about the EFCS is not used at all. How does the exposure start without a first curtain mechanical or otherwise? I'd greatly appreciate a reference so I can learn more. I'll have to do a followup video or take this down and start over. Thanks!

    I'm using E-M10 and when I change "release lag time" from short to normal or normal to short and return to live view, I'll hear some kind of motor actuation. In your other video, you said it only changes the polling rate of the shutter button. Why does it need to make that sound?

    • @RobTrek
      @RobTrek  6 ปีที่แล้ว

      Apparently, I didn't do my research and gave the wrong information! :( It seems the "short" release lag mode actually uses more power to physically actuate the shutter faster. I couldn't find any "official" references, but did find a quote here: www.imaging-resource.com/PRODS/olympus-ep5/olympus-ep5A.HTM . "There's also a new short release-time lag mode, which increases power consumption by around one-fifth, but decreases prefocused shutter lag by around the same margin. Olympus is claiming a time of around 0.049 second, which would gel well with a 20% reduction over the 0.060 second we measured for the E-P3. In our tests the E-P5's shutter lag wasn't quite as fast as claimed, but it was close at 0.052 second." Sorry about that.

    • @hohowtf
      @hohowtf 6 ปีที่แล้ว +1

      Thank you and no worries about the wrong information! I've been searching for the answer for a long time but not one is this close. This explains the sound it makes when the settings are changed. The shutter can have a higher acceleration from stationary when the coils are always energized. This, and with higher current through the coils, frequency can be increased, hence the higher shutter rate. That's what I would guess with these information :)

    Hi Rob. Maybe a very stupid question, but if the sensor can be switched on or off, why do you need a shutter curtain? That doesn't make any sense to me and is very confusing.

    • @RobTrek
      @RobTrek  5 ปีที่แล้ว +3

      The sensor is on, but the camera can only read each row of pixels at roughly 30 or 60 times per second. So if you need a shutter speed faster than 1/60th, then the only way to do that is by cutting off the light with a mechanical shutter so the sensor doesn't get overexposed while the camera reads the pixels. That's why video modes (when the shutter stays open) can only shoot up to 30 or 60fps. Higher frame rates like 120fps are sometimes cropped so the camera doesn't have to read as many pixels. Some cameras like the Panasonic GH5 can do full sensor 120 or 180fps. It requires more power which drains the battery and generates heat. A true full on sensor is called a global shutter, which is what you are thinking. Hope that helps.

    I have a Fujifilm X-T10. It has choices of mechanical, electronic, autoswitch. Flash works only if the mechanical shutter is chosen. I expected it to work for autoswitch because the camera (firmware) could choose mechanical shutter.

    • @RobTrek
      @RobTrek  6 ปีที่แล้ว

      I'm not familiar with Fujifilm, but I would think if you used a Fujifilm brand flash, it should be able to autoswitch. I know when I used my nikon flashes on my olympus camera, the camera can't detect the flash, although it does trigger the flash.

    • @oneeyedphotographer
      @oneeyedphotographer 6 ปีที่แล้ว

      Fujifilm's manual says not. Besides, when I bought it, there were no Fujifilm flashes. There was a NISSIN, rumoured now to be rebranded for Fujifilm.

    • @RobTrek
      @RobTrek  6 ปีที่แล้ว

      Fujifilm is very good about updating firmware, I guess we have to cross our fingers. I should be a simple matter of detecting a flash then forcing mechanical shutter.

    • @oneeyedphotographer
      @oneeyedphotographer 6 ปีที่แล้ว

      Rob Trek no significant updates for this camera. I expected it to use the mechanical shutter within its limits.
      I use it when I feel like wandering random stuff and don't care about which lens I use.
      It's not so important to me, but it might matter to others. It was never going to be my main camera, Fujifilm doesn't have the necessary lenses.

    If the camera does NOT have a electronic global shutter capability, is the mechanical shutter working in conjunction with the electronic rolling shutter?

    • @RobTrek
      @RobTrek  6 ปีที่แล้ว

      In a way, it does. The shutter closes before the camera reads all the data off the sensor so long as the shutter speed is faster than the sensor read speed. I'm looking into sensor read speeds, but I believe it's 1/30th sec to 1/60th, but don't quote me on that. I'm still doing research myself!

    • @doveshouse
      @doveshouse 6 ปีที่แล้ว

      Rob, my sincere thanks for your reply. There are many videos/articles on mechanical vs electronic shutter, but none of them seem to touch upon this specific (in the weeds) point; it is greatly confusing to me. To restate: How in the world does a camera with NO global electronic shutter capability work when using the mechanical shutter??!!

    • @RobTrek
      @RobTrek  6 ปีที่แล้ว

      I'm guessing here, as I'm not a sensor engineer. In electronic shutter, the sensor turns the first row of pixels on and then reads the amount of light each pixel collected before turning off and moving on to the next row. It can do this at 1/16000 as mentioned in the video. Multiply that by 4000 rows and you have 0.25 secs to read top to bottom. However, the camera can turn on the the next row while reading the previous row, so you get a much faster top to bottom rate of maybe 1/30 of sec. Still not fast enough to eliminate rolling shutter effect of skewed lines.
      In mechanical shutter, all of the pixels are turned on at once (like a global shutter), but will stay on until everything is read. So without a way to turn off the sensor fast enough, your exposure would be say 0.25 secs as mentioned above. The problem (as I understand it) is the sensor can't turn off the pixels until everything is read. So we introduce the mechanical shutter to close it's curtains to stop the light from hitting the sensor at the shutter speed chosen to in effect turn off the pixels giving us the proper exposure.
      A true global shutter can turn the sensor's pixels on and off all at the same time, substituting the mechanical shutter, but requires more circuits and more power per pixel introducing noise and lower dynamic range. Global shutters of course exist in very expensive cameras. Affordable cameras will get here eventually, and maybe just around the corner. Who knows?

      They are working on a "global" sensor for the consumer market. There are still some challenges to make it viable. Super high speed cameras like the slow mo guys channel use global shutters, but they weigh and cost a fortune.
