Summary: Digital Slide Copier
Comment: Worked very well once I mastered the focusing and lighting set up. Natural lighting is by far the best and achieved by pointing the camera and slide copier unit at a brightly lit window

Summary: Works fine but doesn't accept thicker plastic framed slides
Comment: Works fine with my Canon XSI w/18-55 Kit Lens. Slides do require minor cropping and tuning after taking the picture of them - nothing to complain about. My only real annoyance with this thing is that it only fits my paper/cardboard style framed slides - my thicker plastic framed slides (many from Germany) do NOT fit in the device. I think I will probably go through all my thinner framed slides first, and then disassemble it and reassamble it with some kind of spacer to make room for the fatter slides. If it wasn't for the issue with the thicker slide frames it would receive 5 stars.

Summary: Pebbly Background; Image Sharpness Degraded
Comment: Look for my comments on the Bower as well. When I ordered a Bower slide copier for its moveable slide stage (pictured with a yellow box), I got this Opteka copier with a fixed slide stage instead (shown with a red box).
The Opteka does have a somewhat sharper lens than the Bower, but that is saying little. The Opteka still degrades image sharpness substantially. My criteria are not that stringent. But there is a very noticeable reduction in image quality when copying with the Opteka. If you are going to copy hundreds or thousands of slides, you should consider whether all of them looking blurry will matter to you. Also, the cheap, thin diffuser on the Opteka has a pebbly texture, which is visible in the image of the slide copy.
The Bower was much worse. The center was sharp, but the edges looked like one of those blurred-out dream scene images you see in the movies. It was almost indescribably poor.
In comparison, the copy of the same slide that I made with a good quality macro lens was far far better than the results from either slide copier.
I can't recommend either slide copying accessory, and I hope I can save you the trouble of buying two different ones to find out that both were unacceptable.

Summary: Slide Copier
Comment: The device worked as advertised. The proper adaptor rings were furnished for my canon zoom lense. A photo bulb and reflective lamp shade works well as a light source for the correct color exposure. Under and over exposed slides can be corrected somewhat. Highly recommended.
