Canon 90D M6ii Lenses - Which have enough Resolving Power? Which Do not?


See list of lenses below the video. This is an ongoing list as we compile more information.



So 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.

Many of these lenses have been confirmed in our FB group: Michael's Canon 90D FB Group

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

The general rule of thumb is that if it is both an older lens and a zoom lens, it might have issues. Most newer zooms and primes seem to do better generally but there are some exceptions.

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
Italics = Likely /Likely Not (Depending on list) based on MTF Charts
