Teleconverters
And to make things even worse there are the teleconverters. These
are lenses that are added to the back of a normal lens to increase
their reach, to add magnification and reach. For instance, a 2x
teleconverters will double the reach of a lens, turning a 100mm lens
into a 200mm lens and so on. Nikon has produced them in 1.4x,
1.7x, and 2x sizes and I have them all. Like the other types of
adaptors, of course they work but how well is the question. Not well
is the answer If you like quality photos. I have the TC-17E II 1.7x,
the TC-14E 1.4x, and the TC-20 E 2x teleconverters from Nikon.
Perhaps the most recent Nikon TC-20E III 2x teleconverter, which I
also have, is better than the rest but still not good enough IMO for
prime time. The sole use for these is to save you from having to
buy a 400mm (or higher magnification) quality telephoto lens. I
don’t blame those who try. Those big lenses that are quality cost a
fortune. Luckily I am a macro shooter. If you must have the added
reach, try them, but I wager that you will be disappointed or at least
end up holding your nose. So I apologize to adaptor fans for my
opinion, which is all it is. I don’t like em’; I don’t use em’.
