As you know, I am a lens addict, and there are very few lenses that still cut it at 100% on the 36MP sensor. The short list is the Sigma 35 and 50 ART, the 85/1.4G, 105 DC (surprisingly), 200/2, ZF 85 & 135, and purportedly the OUTUS's (OUTAE?) will, but I don't own them. Honestly, that's about it. Every other lens I own shows it's weaknesses, usually in the outer 1/3 IC region. Surprisingly, almost any lens is good enough centrally even if it cannot match the sensor. The 24-120 is a good example; undeniably the worst lens in my bag, but it is on the camera for every casual photo event and often as my main travel lens -- and I get fantastic images even printed to 20 or 24 inches.
