This post is about Canon’s “New” FD or FDn 85mm f/1.8 lens which I got from Japan via eBay. There are not many articles on this lens on the Internet; some stuff I found out: it is constructed with 6 elements in 4 groups. The angles of view are 16° vertical and 24° horizontal. The more popular 85mm Canon lens would be the f/1.2 one which is probably why information is so scarce.
I find colour reproduction of this portrait/telephoto lens very acceptable, perhaps due to lack of ghosting and/or flare. Overall sharpness is also good but I often get slightly blurred images due to my own movements when using maximum aperture — couldn’t always nail sharp focus on the eyes when shooting portraiture at 0.85m distance. Will probably need to work more on this, or I could make use of a monopod.
The following photos are taken with Sony Alpha7.
