If you want the bragging rights on your wildlife trip or at an air show, this is the lens for you. What else do we need to say? It's totally awesome in every way. If you need it, you need it, and you know who you are.
The lens is supplied with a dedicated TC800-1.25E ED Teleconverter. When used with this teleconverter, the lens becomes 1000mm f/7. If you do use the 1.25x TC, please bear in mind that it will be manual focus only on a lot of older or 'consumer' grade cameras. We imagine if you're looking at this, you probably use a modern or professional grade camera!
This lens is not fully compatible with the D2 series, D1 series, D200, D100, D90, D80, D70 series, D3000, D60, D50, D40 series, or 35mm film cameras. And if you have a newer camera which is compatible, make sure you're using the most up-to-date firmware.
