One of the beautiful
things about the Sony NEX series is that they can take lenses from any
SLR system with a simple, non-optical adapter. So it's possible to use
old (or new) Nikon, Canon, Leica or just about any other glass on a NEX
camera. Camera makers design their system to work well together. Each
company uses it's own unique anti-aliasing, infa-red and bayer filters.
What this means is that just because a lens works well in it's native
system doesn't mean it will shine on a Sony NEX. After some use this is
how I've found this lens in particular does on a Sony NEX-5N and NEX-7.
The classic and cheap Nikon 75-150 f/3.5
Series E lens gets along quite well with the NEX-5N and NEX-7. It's
colors look good and there is plenty of contrast. It shines here as
much as it does on the Nikon system, and I prefer it's equilivent
100-200mm on the APS-C sized sensor of the NEX system.
