Nikon has had at least six previous f/2.8 telephoto zooms in this range:
80-200mm f/2.8 ED. This manual focus lens was first introduced in 1978 at Photokina. The lens has a unique rotating tripod collar and was a two-ring design, but only a handful were produced.
80-200mm f/2.8 ED. The most common of the manual focus versions uses a one-ring design and a full depth of field scale engraved on the barrel. The lens is distinguished by a huge 95mm front thread. Introduced in 1982, again, not a lot of these lenses were made.
AF 80-200mm f/2.8 ED. The first of the autofocus versions appeared in 1987. Curiously, unlike most early AF conversions, Nikon appears to have made a few optical changes in this conversion, adding an element and making the front element the standard 77mm size used in most pro lenses.
AF 80-200mm f/2.8D ED IF. The first D version appeared in 1992 and added internal focus (no rotating front element).
AF 80-200mm f/2.8D ED IF. A two-ring version of the classic design appeared next.
AF-S 80-200mm f/2.8D ED IF. In 1999, Nikon added an AF-S version of the two-ring design, making a few other minor changes, as well.
Меня интересует разница между последними версиями(обе новые) двухкольцевых обьективов с мотором и без. Проблемы с "медленным" автофокусом не особо волнуют на безмоторной версии, поскольку есть достаточно опыта фокусироватся вручную.
70-200 неподходит как по экономическим соображениям, так и по отсутсвию кольца диафрагм, хотя вроде говорят что это самый резкий из всей это толпы причем даже с конвертером, но в тоже времяч более подвержен действию зайцев.
