Sorry my bad, it's 35mm f2, was thinking in FF equivalent. My responses in blue.
The Yongnuo 35mm f/2 is, a best, a budget lens. See a sample review HERE
The thing is that a camera like the T3i will be more tolerant of a poor lens than the much more sophisticated 80D. Not only is the 80D's sensor capacity higher (almost twice that of the T3i), but it is a step up in other aspects - to put it simply, you're moving from a consumer-level camera to a PRO-sumer level camera several generations of development later. Building a successful system is a matter of balancing the camera body with the lenses appropriate for it's level of performance. The Yongnuo simply is not in that league.
Also I didn't claim any of these photos are "the best" they were just taken from the same place with 2 cameras without any proper lightning, just in an attempt to compare bodies. What I meant is that t3i performed better on some scenes and 80d on others. Conditions weren't ideal so that I can clearly see flaws which as you can see there are many. I understand there's a ton to improve these photos, but it's kinda out of scope for this exercise 😉
When you send images in for review of the technical merits of equipment, you need to take every effort to take out of the equation the human element. That means being very careful that focus and exposure settings are appropriate, and consistent between the two camera for starters.
Looking at the photo blow-ups that Ebiggs1 displayed it appears that your point of focus is actually about a foot closer to the camera than the side table. In fact the light on the far right seems to be reasonably sharp. So either you did not focus on what you thought you had, or the lens was badly mis-focusing.
(I am curious as to whether you used autofocus or manual focusing here: you should use autofocus)
That being said, thank you very much for your help with the analysis, it was very helpful. There's definitely a lot to keep in mind, but I think overall my conclusion is IQ between these cameras didn't improve that much (although still 80d is better in many aspects). More of an eveolution that revolution.
I'm thinking about just switching to mirrorless where I could see a clear improvement though. Just need to decide between sony and canon.
Going Mirrorless will do you no good at all if you cannot get decent shots with the technology you have, arguably it will simply make your shots look worse. So you need to establish what is wrong with what you have and stop blaming the cameras - the likelihood of the 80D not performing is much less than the lens giving poor results or using bad technique.
On technique: do you shoot via the viewfinder or the LCD display? If you do the latter, I suggest using the viewfinder for shooting with both cameras as you then have three points of support for the camera. Holding the camera away from you (like a cell phone) is an unstable platform and liable to give you camera shake.
So: I suggest you take some time to do the following:
- Make sure the cameras are both set to their default settings initially, but reset the image quality to RAW and Hi-Res JPG
- Find a place with plenty of consistent light and without objects that will move, but have clearly defined shapes and tones
- Make sure both cameras are set to autofocus - for this purpose I would suggest using spot focusing so you can be sure to focus on the same point exactly. Be very careful to avoid camera shake - you could use a tripod if necessary.
- Endeavour to set the framing consistently between the two cameras
- With the cameras set to Av mode, take photos at f2, f5.6, f8 for each camera
- Do this for ISO 160, 320 and 400 - so you are looking at about 9 shots total.
- If you have a second lens, repeat the procedure - if it is a zoom lens use the same focal length between both cameras
Review the JPGs on a computer screen that is preferably calibrated to render correct colour, gamma and tone - you should be doing that for any photos you take.
If you want to have us review the results I am sure we will be happy to help, but you have to provide viable material to work with and be sure to reduce the variables in the experiment so we can narrow down the issues.
