Hello, everybody! Do you know about the story of “Long Long Man“? It is a love story about a woman who is torn between his lover and a third-wheel in their relationship, a love triangle like no other with a twist at the end. It is an amazing story that can be considered a modern classic, it’s something that we should all watch at least once in our lifetimes. Watching that very short movie will help you appreciate what you are about to read in this article today. It’s also about something long, but unlike “Long Long Man“, it does not end in tragedy but there’s a little bit of a plot twist with this lens’ barrel construction.
Introduction:
The Nikkor 400mm f/5.6 ED-IF Ai-S is a masterpiece. It was made from 1982 up until 2002, a long 20-year run which is kind of unusual for a lens of this kind in my opinion. On the other hand, it’s understandable because it’s considered to be an exemplary performer. The Nikkor 400mm f/5.6 ED-IF Ai that came before is optically similar to this one except that the tripod collar is narrower. At least that’s the most obvious of all external distinction between both lenses. There may be some differences internally but I can’t confirm. This lens has a huge following amongst bird shooters and train spotters because of its weight and stellar optical performance. Very few lenses of this type could match it in terms of popularity, these are always in demand. For that very reason, it’s not easy to find a cheap one but I got really lucky and I’ll tell you why.
It is long, huge and black. The build quality is exceptional, fit for professional use. It is also very heavy so a tripod collar is supplied with the lens. Unfortunately, mind did not come with it so I was able to buy it for a very cheap price. There are three rings that you manipulate with – the aperture ring, a focusing ring and another ring that allows you to sort of constraint the range of the focusing ring, we’ll talk about it later. Its barrel never extends nor retracts as you focus because it’s an IF (internal focusing) design, this is helpful if you mount it on a tripod and doing precision work since the balance of the lens doesn’t change.
