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

Compatibility does not mean exact same behavior. It just means that the lens will work and the body can control it fully.

With re: to the power consumption of the EVF, I knew I had read this in several places including past threads on this very board.

Fascinating! Thanks for posting that.

For me, (and I assume this is true for most of us) which I am using (EVF vs. big LCD) completely depends on what I am shooting, where I am shooting etc.
Since the R is the only EOS one I own with a swiveling screen, I am learning to reach for it above all others for a number of shooting situations where the big LCD is far preferable that using a viewfinder.

When i was selling some lenses in the market, all the shots were with the R, and I never had to end over peak through the viewfinder. It just makes life so much easier.

I wear readers now that I'm older, and I find it to be a tremendous PITA to my photography. I really don't like shooting with them on so that mostly kills a rear screen option for me in most cases. I won't buy a camera anymore that doesn't at least have an EVF option.

Me too. Thanks for posting.

With my extreme myopia, this is one of the reasons I never got Lasik. My uncorrected vision is sharp at six inches. I wear narrow-frame glasses and just peek over the top.

Just out of curiosity still scouring the net trying to find the answer to why IS needs to run for 45 seconds after a shot. What is the purpose of that. I came across a few things. Some negative reviews about no IBIS which offers 5-axis stabilization. Most competitor MLIC's offer IBIS. Canon claiming that you get better stabilization via the lens. Others saying it is a cop out and Canon is misleading. You know all that usual internet stuff.

I don't shoot movies so I don't really care but I found this interesting. Not sure about the source but the part at the end about Movie Digital IS (at the end) is interesting, if in fact it is accurate. Thought it may make for an interesting discussion.

It might be interesting if a company tried using a very-high-resolution 24x36 sensor as though it were the APS-H format with digital motion correction. Let the image float over the sensor and then correct the motion digitally rather than trying to move the sensor physically.

The problem I see with that is that the individual sensor sites will be unequally exposed thus you are going to get all kinds of artifacting with some sites over exposed, some just right, and some under exposed. Imagin a typical camera shake issue needing 1/60th exposure. The shutter opens and one pixel gets 1/125th of the exposure but the image moves by one pixel so it's no longer being exposed but the one next to is is being exposed ffor the rest. Now you have 2 pixels each being under exposed. By moving the sensor it keeps the individual pixels exposing the same part of the image for the full time.

What I described is what I think electronic motion correction already does in the EOS R, which is why it's a "cropped mode" feature.

I don't think it should be that difficult to compute the necessary gain for underexposed sensels based on the exposure of sensels around them and the differentiation of the exposure of that sensel over the duration of the image exposure.

Interesting take on Fv mode for those considering using it.

their argument is way outdated, Panasonic, for some reason, removed it for one camera....... therefore canon is ok. It could be something to do with that particular type of sensor, because it appears with other cameras that dont have IBIS. Guess what, Panasonic included IBIS for their three newer FF cameras that came out, including a highly specialized video camera, their highest end model...... they all have IBIS. Digital IS has it's place and I do wish that cameras would provide internal Gyro info instead of Digital IS, so you can apply in post much faster. Problem with digital IS is the loss of FOV, and when shake is too much, you get blurry video snippets.

it's the canon games, they will likely give it in future models, and people will forget about the Canon Cripple hammer.

4K crop is a much bigger offender than IBIS as far as I'm concerned, you can do some tricks to stabilize, but no way you're getting FOV back. Cropped video offers no advantage since all other manufacturers offer cropped video as well....

Currently shooting with 7D mkII, upgrading soon. I am turning towards Sony a7R IV

Convince me otherwise.

That was what I read but I just skimmed as I don’t care about video. Thanks for the info.

Ease of use/transition(this is major), 5 FPS tracking vs 3 on adapted lenses, price.... less than half when factoring loyalty program, articulating screen, lcd panel is much better on the canon, very best 50 and 85 on the market (also biggest and most expensive). RF 24-105/35 f1.8 is a bargain compared to Sony.

If you’re intent On high resolution, canon doesn’t compare currently.
