Where is that CZ 85? Any word yet?
RE:90 AA--big, heavy, somewhat soft until f5.6. I traded this in for 90 Elmarit-M: Smaller, lighter, performance wide open is fine, and sharper from f4 on. Though the size was the primary factor. I had/have no focus problems on either wide open, at short distances, or otherwise, on an M6ttl, and MP. I use/have used Leica, CZ, Konica, & VC lenses on my Leicas. The CZ wides are great, the Leica 50 & 90's are great, the VC, ultra fast wides, and ultra wide wides are great. We are very lucky to have so many brands of excellent M lenses ranging from VERY affordable, to legendary, sell-your-first-born- expensive. Even in the LH/A publications they ACTUALLY discuss the CZ's, and VC's M-mounts, without disdain...
