I purchased both the ZA 85 and 135 for my A900 and love them both -- but I can only justify keeping one of them.
The lens rarely left the house and had a CP on 99% of the time. Glass is perfect, barrel condition 99% (one spot of paint wear on the rim - shown below)
I'm asking $1100 , includes lens, both caps, hood, leather case, store brand CP filter, and insured shipping within CONUS.
