I am looking for the best ~300mm lens mountable on a D800. Max aperture is not important, I could us f8 if it delivers better results.
One major constraint, it should weight max around 2kg which excludes most of the f2.8 lenses (I already own a nikkor 300f2.8 VR).
I have tried the nikkor 300f4, but its tripod collar is such a disaster that it makes it very hard to get sharp results.
My current top candidate is the Leica R 280 f4 APO, but are there better options (MF lenses,...)?
Thanks.
Cheers,
Bernard
