I have a host of enthusiastic Nikon lenses to go with my Nikon FF D600.
I have a AF-S 16-35mm f4 VR, AF-S 24-120mm f4 VR, and 80-200mm f2.8D screw-driven lens with which a TC is not usable except in manual focus. On the prime side I have the Nikon 50mm f1.8 and the Tamron 90mmm f2.8 Macro.
I wanted something further in reach beyond 200mm, so bought the very sharp 70-300mm VR lens. I then felt I needed further reach to 400mm or beyond to get wildlife and other photography.
I started a very frustrating trip for an amateur enthusiastic photographer.
The obvious choice was the Nikon 80-400mm VR. I read so many reviews about how the MKI was very slow to focus and created a lot of tug while screw-drive focusing. The reviews also indicated it was soft wide open, especially at the 400mm end, which is what I would have got it for. They also indicated it suffered from focus breathing, especially at very near distances, producing a field of view similar to a lens <300mm. It is still being produced and a new one sells for around £900, while a used one is around £500. I decided to skip this option.
The next choice was the 80-400mm VR MKII. It seems to have all the above sorted except for the focus breathing, and for the fact that it is almost twice as expensive at about £1900, with hardly any used ones are available for a more reasonable price. This was beyond my budget.
The next thought was do I change systems from Nikon to Canon to get the Canon 100-400L IS, which is an excellent lens, not as expensive as the Nikon 80-400mm and is available as used around £800. I felt that changing systems is such a drastic measure, especially as I really like all my other lenses, and I love my Nikon cameras.
The next option was still within Nikon perhaps get a 70-200mm f2.8 + TC2.0 which would set me back £1800 and is huge and heavy, that was not an option, or a 70-200mm f4 + TC1.4, which is not terribly expensive but <300mm and f5.6, so no real improvement, or a 300mm f4 + TC1.4 and that is more than 400mm and f5.6. I kind of decided against the latter as my use is not necessarily for far away birds only.
The last option was a Tamron or a Sigma. There are quite a few of them reaching 300, 400 and even 500mm, but very big and heavy, and all their reviews indicated a not very sharp image at the far reach, which is my needed reach.
For now I settled for the 70-300 VR, hoping for the price of the 80-400mm MKII to come down and to find a well priced used one within my budget.
I would be interested in hearing people’s comments on the 400mm end on a Nikon ?
