Do you remember the Titanium bladed shutter Nikon used in its Nikkormat line? … Was that close to being perfect, or no? … The cloth shutter used in the other Nikon cameras, has limited use, apparently. The search is on for something better. The electronic shutter used in many cameras, today - solved the quietness thing - but brought with it - a host of new problems. What kind of shutter do we need, to solve all hitches. Is there such a thing? … If so, is there a way to make it affordable enough, so it can be incorporated in all dig cams? … Is there a future, for such a device in today's DSLRs and MILCs, or is getting there still a fantasy?

Yes, the perfect shutter is already being used by first Panasonic and Olympus and now some others. It is called the electronic shutter. There are no moving parts and is activated by locking the mechanical shutter open. This allows at least the Olympus E-M10 mrII, E-M10 mrIII, E-M5 mrII, E-M1mrII, and the new E-M1X shoot at 60 fps. It can be sampled at your local camera store. Bring very big chips. At 60 fps, chips fill up quick.

If it's perfect why do they still have the mechanical shutter?

The electronic shutter, though, WD - creates other problems - to do with distortion - the rolling shutter effect
… this is NOT the perfect solution, apparently. We need something, beyond this, WD …

All of these MFT models, though, WD - provide one with an option of regular vs. electronic. Why would they do that with the E-M10 Mk. II, E-M10 Mk. III, E-M5 Mk. II, E-M1 Mk. II, and E-M1X - if it weren't necessary?

Hey, Haydon … Get a Life - why don'tcha?

Hey Chris! I think the perfect shutter would be the electronic one without the problem of rolling shutter. I think they will get there in a few years.

Chris T Loc: from England across the pond to New England

I guess I agree with you, there, Bebu … but, it seems to be a long time coming …

R&D departments, all over the world, are working on it, as we speak ….

I think, though - the electronic shutter was put to market, before it was really ready …

Haydon is not wrong. My guess is that you need to get out from behind the keyboard and actually take some pictures. Dreaming up these inane topics you have been coming up with since you joined UHH must occupy most of your waking hours. It's a sign that your topics are not interesting to anyone but yourself. In this thread, you have ten posts, 5 of which are yours, and none of the other posts take the topic seriously. Maybe you might want to take your own advice for everyone's sake . . . Just sayin'

This last batch contained only four, actually, Gene - and I didn't "dream them up" as you put it. All four of them came out of discussions which developed during comments made on other people's Topic Posts. Right now, Gene - we, here, in the northeast, are experiencing several snow-storms, one after the other. So, the idea I'm going to get out to shoot, anytime soon - is remote. However, I'm having fun, practicing my skills at Product Photography - shooting my cameras, almost every day. Sorry you consider them "inane" Gene. Most of the folks who answer on them, clearly, don't agree with you, or they wouldn't have answered.

BTW, Gene - the last time Haydon did this - just about a week ago, actually - there was a barrage of folks answering old Topic Posts of mine, at the same time I'd put up a couple of new posts one day, and followed by a couple more, the next day - the way I used to do it - before the storms in March and May took me off-line for a month or two. All of these Topic Posts (except one from six months, ago) - were from a year or more, ago. All I can say is this - if they are so "inane" - why do people looking at the list from a year or more ago - find them interesting enough, to want to comment on them? … Don't think your characterizations of my writing efforts, Gene - are global - as, apparently - that is NOT the case …

You know what I found "inane" Gene? … It's the need to address comments like the ones you and Haydon make. That's TRULY inane!!!!!

No it wasn't too early. As long as one understands where it is useful and where it is not, there is no problem. The shutter effect is only a problem with things that move too fast. It is much reduced on the Sony A9, but there is still a ways to go. There is also the issue with electronic flashes. And the problem with banding caused by certain light sources. But for most everything else, it works quite well.

I have it, and I use it, and no, I don't want to get rid of it.

Actually the way to implement global shutter is well understood. The problem is that the complexity of the sensor has to take a big jump. And this is what is holding it back. There is a need to hold many pixels worth of data in the sensor while that data is being read from the sensor. The band aid solution is what they use today where they expose only part of the sensor to light and to then keep moving a slit across the sensor while the sensor is read at the same rate. This allows the rolling shutter action to happen since this takes time. Some day, they will be able to increase the density of electronics on the sensor and to capture and read at a rate that has no rolling shutter. Until that day arrives, we keep what we have.

Jim - if the electronic shutter is prone to producing distortion via the "rolling shutter" effect - when used for shooting moving objects - it would seem to me, it was brought to market, way too soon. After all - how often can we be sure, before initiating a shoot - the subject isn't going to move during our patient attempts to compose, focus, and set the shutter speed, aperture, and ISO (or foregoing all that, and using "P") ???

Now, I see you've pointed out several other problems with it - including banding, and syncing with electronic flashes. It seems to me - if it were truly ready for market - they would have dealt with all of these problems, before incorporating them into new camera designs. Don'tchathink, Jim?

"Increasing the density of the electronics on the sensor" Jim? … Do you mean like adding a zillion focal points, like Canon did, with their new R? … What IS that one? … Something like 5,665 - is it, Jim?

If I recall, the Sony A9’s electronic shutter doesn’t suffer from rolling.

Chris T Loc: from England across the pond to New England

It doesn't, huh, Tom … not like the one employed by Olympus, in their new E-M1X and in the E-M1 II ???

So, then - the Sony a9 has a better employment of the electronic shutter than Olympus's more recent effort?
