So fast the Zenitar 16mm F2.8 Fisheye is reserved.
One day liao ...
AT $220, definitely people will snap up.
But with the Zenitars, you have to really chewc the lens/adapter beri carefully because not all adapters will allow you to focus to infinity.
I would prefer to spend $400+ and get a 2nd hand Sigma 15mm FE with much higher and also much more consistent performance.
