As you can see, this is plenty of great guys. Now you know that all
you need is a very cheap adapter (macro coupler ring and, probably,
step-up or down ring). I set the 50 mm lens at maximum aperture
(1,8 in my case), to avoid vignetting (just a little on the corners
this way), and to get more light; I set the focus at infinite. On
the other side, I use the 5700 full telephoto (once again to avoid
vignetting, and to get more magnification as well), and set the
manual focus at the shortest distance (MF bar to the left). The
camera will "tell" you that it will be not able to focus (red bar),
but don't believe it. Try to focus manually getting closer, step by
step, to the subject. With a little practice you'll see clearly the
subject and... what a shallow DOF you have! But shoot anyway. It's
digital. It's free. And finally you'll get some good pictures of
almost every subject.
Best regards!
I had a look at the links and at least now I know the theory of the
operation. I checked my old 35mm stuff and I did find an old 50mm
lense.
Did you have to fabricate the reversing adaptor? I'm curious to
hear about your setup as I also have the 5700.
The page I mentioned in my previous mail provides a complete setup
of doing lens reversing for close-up photography. The ring you
want is usually referred to as a macro coupler and is available in
many camera stores. For example, B&H
http://www.bhphoto.com and
Adorama
http://www.adorama.com all have it. It costs only a couple
of dollars. The reverslely mounted 35mm lens must be a very good,
especially flat field, one to yield the best results. You might
also want to close the aperture down to f5.6 or f8.0 Please use
the calculation on my page to determine the magnification. The
most popular and affordable reversible Nikon lens is Nikon 24mm
f2.8.
Hope this helps.
