As I’ve mentioned before, I decide to sell this lens every few months. It’s the last remaining lens from my film days; I bought it around the time my son was born, 23 years ago.
I get frustrated with this lens because it does not always focus accurately. When it does, I always like the results. Moreover, when I read reviews of those sexy 85mm f/1.4 lenses, people say they don’t always focus accurately, but when they do, etc…
When I feel like selling this lens, I put it on a camera for a few days, take some pictures, and save myself a thousand dollars or more. Yet, every time I get into a dimly lit theater or club, the fast glass envy seeps into my brain.
Subject isolation is the specialty of fast telephoto lenses, so they are considered a top choice for portraiture. I’ve been using another lens for portraits for the last couple of years, because, as I mentioned above, I’ve encountered some focus problems with this, particularly in low light. With a fast telephoto, focus accuracy is really important, because depth-of-field gets very narrow at f/1.8 or f/1.4. The extra effort is amply rewarded by the quality images such a lens can produce.
