$293 to $17. Quite a price range
for similar items.There isn't too much to a Nikon to NEX adapter. It's
basically just an extension tube with two a Nikon F mount on the front
and Sony E on the rear.. Due to the lack of an aperture ring on G
lenses, a suitable adapter also needs to a ring to control the aperture
lever on the rear of the lens. I chose this particular one because of
the price and inclusion of a tripod mount. The Sony NEX are quite
lacking in this area, and I wouldn't want to throw my Nikkor 70-300VR
on my NEX-5N with just the body attached to a tripod.
So how does this particular $40 model stack up? To be honest not
particularly well. The tripod mount is only attached by two tiny screws
which constantly come loose. You can see my addition of epoxy to hold
them in place and help make the tiny tripod mount a little more solid.
The next thing a lens adapter needs to do well is form a firm
connection from the lens to the camera. Unfortunately the Fotodiox
falls a bit short in that category too, it's a bit loose and both
mounts have some play.
You might think that would be it, but it has one
more issue! If you use an AI or AI-S lens and want to
use the aperture ring on the lens, the release button blocks full
rotation of the aperture ring. Why would you want to use the aperture
ring on the lens? With no markings on the adapter ring for
aperture control, it's also near impossible to tell what the aperture
is adjusted to. You can still open the lens all the way, either via the
aperture ring on the adapter (but you won't know your exact aperture)
or you can pull the release lever back and move the lens aperture ring
to its widest setting. An annoying oversight in the design of this
In short, it gets the job done, but is not particularly
well designed or machined, but not particularly expensive either.
after considerable use I noticed a massive flaw in the Fotodiox
adapter. The release lever for the Nikon lens lets in light when a lens
is attached. Bad news! After one year the lens release button broke
rendering this adapter useless.
