I have a nikon D7100 and 80-400, 18-200, 50/1.4, all nikon and a Tokina wide angle lens. I take skiing and mountain biking races and find the 18-200 lens autofocus slow, the 80-400 is fast enough and I have to use the 50mm and tokina lens more to be sure about them as the focal plane is so narrow.
Any suggestions on fast autofocus lens for my consideration, especially to replace the 18-200, but other options also welcome.
Thanks in advance.
To achieve a 11:1 zoom ratio many compromises are needed. Not only is this lens slow, optical quality is mediocre. There are many lenses that will out perform it in every way but zoom ratio.
A nice lens to compliment the 80-400mm with out spending much is the Nikkor AF-S 16-85mm f/3-5-5.6G ED VR DX.
