Happy news here: I finally bought a lens I wanted for quite some time. I found and paid on eBay a Minolta APO G 400mm f/4.5 (Yes! The old white lens that is renowned so much for its optical and mechanical quality, while being nearly impossible to find in auctions).
It will go really well with the Giottos MT 8251 carbon tripod and the MH 1001-652 ball-head I bought a month ago in Shanghai, People’s Republic of China.
Soon to arrive from Osaka, Japan. I can’t wait.
