Hotspots, flare, blur with wide-spectrum filters (due to non-wide-spectrum-APO), please?
Many thanks!

For the less than fully omni-literate among us, Mr. Dick's invaluable input translates as "I don't know".
Given that, as per Mr. Dick's own count, this is his 2022nd attempt to help his fellow man by sharing wisdom, I eagerly await his 2023rd!

I have not tried it yet- have a full spectrum EOS RP.. however, historically, the RF lenses have not performed the best on the IR converted bodies.

I am hoping to try the 7-14 soon (just been too damn cold here in NY) since I have the drop in filters for IR that will easily match.. Still, think the RF lenses are not kind to IR

Many thanks! I heard the same input, but, allegedly, 14-35 is quite usable (if you don't close it down too much), so I am hoping 10-20 is the same. I did not know 7-14 was out -- big thanks for the heads-up! Please post here your results with 7-14 fisheye as well as with 10-20. Huge thanks!!!
