Works well
It takes a bit of experimentation to get the images to be "vignette free", but overall this is a nice low tech / high tech solution. Contrary to the technical details description, this product is made in China, not Japan.

Quick and Simple
This product is great. I received it from 47th Street photo in a few days. I have a dedicated slide scanner(Minolta DiMage Scan Dual 4). The Minolta works great but would have taken ages since I have a few thousand images to scan. I used the Opteka with a Nikon D70 (I didn't want to wear down the shutter on my D300) and a 50mm 1.8 prime lens. The filter thread size on this lens is 52mm like the Opteka. At f9 it works great. It works best with daylight, but do not point it directly towards a bright sun because the image will look very grainy. Possibly due to the matte translucent backing on the unit. The image fills about 70% of the screen. I ordered a 62-52mm stepdown ring to use it with my 60mm 2.8 Nikor Macro, it did a better job of filling the screen and picture quality was a little sharper. I'm pretty happy with the speed that I'm able to do this and the color is great. NEF should give you even more control of the results.

Very good and cheap
Very good and cheap
I had to backup about 6000 Slides and this is a very good way of doing it.
Easy to use and you have to put it in the lens, I have a 50 mm and I had no problem in doing it.
Nice and cheap.

What you need to avoid having to scan your slide photos!
The only reason I don't give five stars to this product is that it should include the option on purchase of picking out the ring size you need for your lens. Or the right step up or step down rings.
As it is now, I had to get a separate set of step down rings to be able to use it.

Good Inexpensive Slide Copier
This is a good slide copier for the money. You will get better results if you want to pony up a few hundred dollars for a professional side and negative scanner. I found it a bit laborious to insert each slide, then refocus my camera for each one. I wouldn't want to tackle the job of copying a few hundred slides with it, but if you have a couple of dozen at a time to copy, then it will work fine. I thought the overall quality of the copies wasn't bad. I used a Nikon D40X with the 18-55mm lens.
