If this was the MK1 100-400 that lens was borderline on being sharp enough at best

a friend of mine had one and he never got good results with it unlike some other lenses he had

So I just did some quick and dirty tests. Below are some 100% center crops of a house around 100 yards away. ISO is 100 for the 100mm shot and 200 for the 400mm shot so noise should be a non-issue.  Since I'm technically working today, I'm stuck shooting through my window, which is very clean, but is going to add some softness. I'll do a proper outdoor test later.

I processed the raws via DXO Photolab with only default normal noise reduction (no DeepPrime magic) and lens sharpness/correction applied. I did not apply other sharpening or adjustments. So while this is not completely "out-of-camera," I would never use shots from this lens without lens correction applied.

All in all, it's not bad, and way better than what I was getting on my DSLRs. Definitely not as sharp as other lenses though. My 100m 2.8L Macro is surgically sharp.

This is a 100% center crop of a house at 100mm.

This is a 100% center crop of the same house at 400mm.
