2. If a lens isn't on this list, I strongly recommend searching our facebook group for the name of the list to see examples: Michael's Canon 90D Facebook Users Group
3. The general rule of thumb is that if it is both an older lens and a zoom lens, it might have issues. Older lenses mean the design of the lens is greater than 10 years. Most newer zooms and primes seem to do better generally but there are some exceptions.
The Canon 90D Sensor (and M6II) have a pixel pitch of about 3.2 microns, which means lenses used will likely need to have better resolving power than the list Canon Recommended for the 5Ds and 5DSR:
Canon's Lens Recommendations For the 5DS and 5DSR. I have added a couple to this list that should have enough:
Confirmed = Multiple Users have demonstrated with images on our FB group
Unconfirmed = Verbal Only from different sources
50/50- Some good, some bad examples from the FB group, might come down to the copy you have or how stopped down your aperture is.
Italics = Likely /Likely Not (Depending on list) based on MTF Charts
Zoom Lenses - Tamron 16-300 3.5-6.3 Confirmed Low Resolving ***DISCONTINUED*****
- Tamron 18-270 (No)***DISCONTINUED*****
- Tamron 18-400mm f/3.5-6.3 Di II VC HLD Lens for Canon EF(*We have seen both good and bad images with it, seems like a good copy will work, better when stopped down)
- Tamron 100-400mm f/4.5-6.3 Di VC USD Lens for Canon EF(50/50)
- Canon 24-70 2.8 I - (Not Great) ***DISCONTINUED*****
- Canon EF 24-105mm f/4L IS I USM, V1 is far worse, V2 is better but may come down to copy.
- Canon 100-400 f4.5-5.6 v1 (very soft at the 400mm Focal Length)(Confirmed Low Resolving) - this is one of the worst **DISCONTINUED*****
