EOS R TECH THREAD- Its time for others who will jump into canon Mirrorless bodies

digital paradise wrote in post #18982780
I have never turned it off since 2006. An exception as a tripod and sometimes I'd forget but I don't use one that often. I had to with the 300 F4 iS as that generation did not auto detect no movement. I use with a monopod sometimes at 800mm and it helps.

The manuals warn about battery life and I can't see it not effecting it. Of course you can just change it. In one scenario my test showed it ran for 90 seconds and that was if the viewfinder did not detect something and start over. You would think that if it didn't run for all that extra time it would make a difference. There must a reason why there is a 2 second shut off with a DSLR.

I have read about and been long aware of IS and higher shutter speeds. I have not noticed a major negative effect as I always come home with plenty of keepers. Also that is what mode 3 is for. These were from my 2nd day out with my 7D and 300 F4 in 2009. I think the shutter speeds were around 1/5000 with IS on. People told me not to use it but I was getting my feet wet with BIF and just wanted to get the shots to build confidence.

That being said I don’t disagree that IS can cause issues with initial AF and moving targets. This is based on what I had read. Turning it off is a good idea but I choose not to. Like I said that is what mode 3 is for.

There are so many reports of the LP-E6 running 2-3x the stated time that Canon put out at the R's announcement, and therefore I have to believe that the continuous IS just isn't that detrimental to battery life. Chances are that reviewing images and looking at menus and the EVF being on have more to do with battery life than the IS system. The M50 is terrible with its little battery, and I eek out about 200-300 tops on that camera, and I have a few lenses with IS.

Trying to get to the bottom of this with Canon is wasted effort. They are simply going to say that is how this is engineered, they are looking at alternatives in future models, and there will be no update of any kind to the R/RP/M series to fix this at this time.

I agree. I am going to give them a call anyway and try get a few levels up but I don’t expect much.

Thanks for your feedback. Always appreciated.

Keep us appraised, and I am sure you are right, the first couple levels won't know what is going on or how to answer your questions.

On a side note, my R is just a tad worse at ISO 25600, but I hope that changes with continued use. My 5D4 seemed to get cleaner over the course of an NBA season and I suspect the same will happen with the R.

A DSLR doesn't need IS except when it's actually recording the picture unless I'm missing something. It's easy enough to know when to turn IS off if the mirror is down and there's no way a picture can be recorded. Mirrorless simply doesn't work that way. There simply is no mechanical mechanism or any other that can be sensored in a way to detect when a shot may be taken.

Lest we also forget that there was no viewfinder stabilization on DSLRs. It was a mirror, and if the mirror moved, the image shook, but it was our FAST human eye that saw it (More on that in a minute.). We all accepted it because it was part and parcel of the "cost of doing business," and it didn't bother most of us because our eyes are "fast enough" to never really see it anyway. Great solution, huh?

IS also aids in the apparent stability of a mirrorless and it's electronic counterpart, whether it be a screen in a viewfinder or the screen elsewhere on the camera. Aside from the obvious stability it provides us as users viewing the image, could you imagine the refresh times (and hence expense) of screens that refreshed quickly enough to actually show the instabilities?

Again, to me it's all about compromising what must be compromised in today's engineering and known physics. I would challenge you that the "problem" they perceive as so easily solved, may not be as practically solvable as it may seem on the surface, and even if they did, people might like the solution and the new problems it creates even less.

B.I.N.G.O.

Somebody answer a question for me because I'm too lazy to break out one of my DSLRs and a stethoscope to check. Is IS on with a DSLR when "live view" is enabled? My bet would be yes. Somebody tell me I'm wrong.

I’ll get the ear goggles out and try it later. I think found the IS part in a DSLR for LV. Runs all of the time and it is word for word in the R and RP manuals.

Sunday night trivia: What camera company supporting lens IS with no sensor stabilization operates the way you guys think it should operate in a mirrorless system? By that, I mean turning off IS completely except when a picture is being taken.

I'll wait.

This, exactly.

Unlike those of you outdoors photographing ducks, some of us photograph indoors 99% of the time, often in dimly lit venues. IS is "ON" 100% of the time. I bought an R primarly to be able to use the RF 24-70 IS lens, since Canon never produced an IS version of that lens in the EF mount. Higher shutter speeds are a rare luxury. Using the switch on the lens, solely to preserve battery life, is an unacceptable "solution" to a design flaw.

There is NO reason why Canon cannot provide an option for IS to power down/off after each shot, or after pressure is removed from the shutter or BBF button. Just give us the same setup option as existed on all the camera bodies until now. Still photography and movie mode need not be the same.

This is another of those strange design elements that are step back from previous Canon bodies. Having the rear screen "on" all the time, when one wants it solely for image review, is another. Yeah, there's a workaround for that, but it then takes two button presses to accomplish what was done with only one until now.

Seems to me both these issues could be resolved in a firmware update. If only someone is listening. It should not take a second generation "R" body to fix something that wasn't broken on the dslr bodies.

I shoot indoors and low light but still run higher shutter speeds. Of course I run high ISO to help, and sometimes will engage IS, but I am pretty darn steady even in my old age.

.

Press the INFO button a few times and use the old style info page,it behaves the same as the standard DSLR display you are used to.

Please explain this further. I want to use the rear screen to review images, zoom in, etc. So far, the only workaround I've seen is to program a button to switch between the EVF and the rear screen. When the rear screen is "live," one then presses the review button. Once finished with the review, it's necessary to press the programmed button again to switch back to the EVF. Otherwise the rear screen remains illuminated, in live view mode.

How does the info button affect this behavior?

This sounds like an argument against including IS, either in lens, or in body. Really, are we headed back to those debates, after we've had IS on many lenses, for two decades already? Maybe you're pretty darn steady, steadier than others. Having seen some of your work, I'd say "probably." Maybe your version of indoors and low light is brighter than that of others. Could be.

All I know, I find myself between iso 6400 and 12800 for a large percentage of my images, and it's a rarity when I can get shutter speed faster than 1/250th. Even when it is bright enough, there are times where a slower shutter speed is desired for an effect, or more depth of field is in order. IS helps for all of that. I have a higher keeper rate of sharp images from the 70-200/2.8 L IS II than I do from the unstabilized 24-70/2.8 (on the 5D4). The 135/2L gets left at home, even for dark venues, in favor of the stabilized zoom. I was very happy Canon released the 85/1.4L IS.

This particular discussion has to do with a difference between Canon's dslr's and mirrorless cameras, regarding IS running whenever the camera is not in sleep mode. On the R, from all reports, IS is running a whole lot more than on the dslr's, as if the camera is in live view/movie mode all the time. Why should asking for this to be a controllable option, be controversial? Just like IS: if you don't want to use it, turn it off. Otherwise, for still photography, Canon ought to have a menu option allowing IS activity to function as it did before. Lens IS could be left "on" all the time, but would only be active after a half-press of the shutter or AF-On button.

Press the info button until you get he standard screen view you would on a DSLR,the camera then behaves like a DSLR in that you can have the preview of shots when taken (2 secs or whatever ), it then returns to the same screen,one press on the view button or whatever it's called lets you view all the photos you've taken as with any DSLR I've used.If you switch the camera off and on again this setup remains until you press the info button to return to live view.Page 62 of the manual.Hope this helps.

When I’m shooting with the EOS-R I have the rear screen in the closed position facing inwards. Any adjustments that I need to make can be made by pressing various buttons and turning dials, and reviewing images can be done through the viewfinder (which I much prefer).
