CANON EOS R - used for multiple exposures. First thoughts.
by Doug

I buy quality cards and I push my cameras hard in all weathers - I don't wrap them in cotton wool (or polythene). Its not so long ago all cameras only had one card and prior to that, one roll of film. We managed somehow. My feeling is that the outrage is just a little over done - and I know that me just saying this will outrage some people. But I am just being honest (but please Canon - get another card slot in ASAP, I am pretty certain your design guys can make one fit).
Now that is dealt with let us get down to the nitty gritty. My first impressions about the camera. The build quality is excellent, as you would expect from Canon. I have big hands but ergonomically it is very comfortable in the hand. The balance is good and I liked the shaped grip. I work with one hand a lot of the time and this suited me well. I was surprised at how light it felt, even with the quality lens fitted. The EF adaptor is ridiculously light - this is because it is, in effect, just an extension tube. There is no glass in it. It just moves the EF lenses further away from the sensor and links up the electronics. So all of the lens functions still work as normal and everything still works in the EVF - you notice no difference in operating the camera. Even with a big lens like the 70-300mm attached it felt well balanced and lighter, obviously, than my 5D mk4. The weight saving is not huge but it is noticeable but it is also physically smaller so when travelling it takes up less bag space and it is less obtrusive in the hand, attracting less attention.
Yes, using your L EF glass brings the weight right up, but you have the quality of the glass and it will be lighter than your DSLR. For some of you the weight saving while using your DSLR lenses will not be enough - but the R lenses are L glass quality and lighter. Canon will widen the range quite rapidly. I am happy to use the 24-105 for now along with my L 70-300 and the adaptor and cope with the weight - while benefitting from the physical size decrease (and it is lighter - noticeably so) while I wait for a lighter 70-300 R lens to be released.You will need to decide for yourself what you can cope with.</div>
The second, and for me game changing improvement for multiple exposure work with the EOS R, is the EVF. This allows you to see the image 'shadowed' as you make each frame. You can't see the effect of the blend mode being applied before you fire the shutter (but you do see, in the EVF the blended image after the next frame is added) however the big advantage is being able to line objects up. This helps hugely with composition.
The next frame you see shadowed in the EVF is 'brighter' and so you need to look closely but it is sufficient to do what you need to do. The EVF also works seamlessly, I was not conscious it was an EVF, to be honest, it didn't interfere it only assisted me. I like to have the camera to my eye when making ME images and previously I had to visualise in my mind where objects would be.
You could use the live view screen, but this slowed the process down and meant holding the camera away at arms length which I found didn't suit my way of working. I was blown away by the difference using the EVF made to my workflow. I am now finding using my 5D mk4 very frustrating indeed. I have opened Pandoras Box!
