Hi everyone, I recently bought a Canon 5DSR to compare against Canon R5. I tried it out on a still life shoot with the camera on a tripod, using flash lighting, and the results were very good. However I then tried doing a fashion shoot with the 5DSR handheld - also using flash, the results were not at all sharp... not just the odd pic but all of the photos... I tried switching to manual focus and whilst the camera was pin sharp through the lens, it was still not sharp at all when viewed in Capture One 21. Any ideas what I might be doing wrong or is this a common fault with this camera? (R5 in the same situation / same lens was absolutely pin btw)
My first guess is that this is a lens related issue, I'm not saying the lens is bad btw, just the issue is likely on the focusing. The focus systems are different, the mirrorless system removes any need to calibrate the body to the lens since the focus is read off the sensor instead of using the mirror in the dslr. What lens are you using?? You should have some top glass on such high MP cameras, but I figure you probably do. With a dSLR you may have to use micro adjustment for the lens to fine tune sharpness, two copies of a lens may have slightly different focus performance, as there is a range of what is considered acceptable by the factory before they are shipped. I will assume your lens is a good copy but may just need you to slightly fine tune the micro adjustment for the 5d. Sometimes bad copies or batches of lenses happen, but that is not normal, but also something one should keep an eye on when getting a new lens; this is something that has been around for years and why companies allow micro adjustment by mid to upper tier bodies. Again, keep in mind your r5 will remove the need for micro adjustment as it is using the sensor directly to focus. Also keep in mind when your pushing 45-50mp you are seeing any flaw very noticeable when pixel peeping.
Stupid question, but since you mention hand held, the 5d being a bit heavier, you aren't pushing a really slow shutter are you which could introduce hand held blur. I know its photo 101 question, i just want to eliminate this as a problem.
Hi Johnsy, thanks for the quick reply. I was shooting 125th at f11 so I don't think that slow shutter ambient is the issue. Very interesting what you say about the R5 working direct with the sensor as opposed to the 5DSR. The lens I was using for the test was an older (first edition) 24-105 F4 L which I have had since new. I have since bought a brand new / latest version, plus a new / latest 16-35 F4. Do you think I should simply try again with these or get the new lenses calibrated to work with my 5DSR? If its of any relevance, also involved with the test was my old 1DS mark 3 which has never been calibrated to work with the lens, it was pin sharp throughout the test. Thanks!
Ok new question, what focus mode are you using, Single / Continuous/ Servo settings may be at play here, If you shoot back button/focus recompose style AI focus could hurt the image, it is a release priority situation preferring speed of focus to accuracy, where as continuous single shot will prioritize focus over speed. I could see why depending on mode and shooting style you could get some different results between tripod and hand held shots. https://community.usa.canon.com/t5/EOS-DSLR-Mirrorless-Cameras/5d-MARK-IV-AI-Servo/td-p/253859 Confirming calibration may be a good idea with a 50mp dslr anyway as any slight calibration would help getting the most out of sharpness, something that may not have even showed at 20mp. It is probably not the solution to the problem as focus should behave same between situations if it was simply the body or lens itself. Focus modes/ and shooting method actually seem to be the culprit now that I thought a bit longer.
Thanks again Johnsey, I have always used my Canons on AI Servo. I will definitely try single shot on the next test. I really want this 5DSR camera to work for me as the R5 has some serious issues with some of the lighting set ups I use often. (extremely low light before strobe fires type of thing). Can calibration be done via my computer? or does the equipment have to go to Canon? Thanks so much for your wisdom btw!
Its done in camera, each camera will know each lens serial attached to it and store the change. Here is a video that gives you a quick overview but you can search a variety of tutorials for more information.
