I don't know this seller, but I do know this model and equipment as I have used it before! If I had a need for more I would jump on this in a heartbeat! Even the BIN @ $189.99 is a smoking deal! It even comes with a slide copier if you wish to convert your film slides over to digital files, or if do not need nor want this attachment, turn back around and sell it on Ebay and you can get around $40-$50 or so for it alone!

All that is needed is a few M42 mount lenses to use the bellows. A 35mm f/2.8, Chinon/Pentax/Yashica Vivitar M42 50/55mm f/1.4 or f/1.8 or f/2, Vivitar/Tamron/Chinon/Pentax M42 135mm f/2.8 or f/3.5, and 20Pentax/Vivitar/Jupiter/Yashica M42 200mm f/4 are typical focal lengths used. You should use a flat field lens, but since you won;t be filling the frame shooting gemstone shots and such, you don't need to bother with a specific macro lens for it, although starting with a 1:1 basis will yield far greater magnifications in the end. You will also need an M42 adapter to your camera's mount, cheap and abundant.

Here are two shots I did testing out bellows when I got my first set for digital.

An agate showing normal view with a battery for size, and the magnified view from the bellows with a 35mm f/3.5 Zeiss lens.

This is a simple grain of table sea salt using the bellows + 68mm stacked TCs + 35mm f/3.5 Zeiss lens

They were shot with a Canon EOS 20D dSLR I believe.
