Review of Digital Optic - Tele/Wide Deluxe Digital Lenses, also know as telephoto conversion camera lens

My photography partner purchased this lens attachment off ebay, thinking it was worth a try since it was cheaper in cost than buying a 400mm lens to go with his Nikon D40 SLR camera. The box also says it's compatible with Sony, Panasonic, JVC, Hitachi, Canon, Pentax, Fuji, Samsung, Kodak and Olympus digital cameras.

In theory it looked great, promising you can zoom right in on objects from quite a long distance away. However, after a couple of days, shooting all types of photographs with it, here is what he had to say about the telephoto conversion lens:

• Every photograph was left with a blue halo or outline surrounding the main subject. This seemed to get worse when the object was positioned in direct sunlight. The instructions said to use the smallest lens opening and set the focus to infinity. This did help marginally with the halo, yet it was still there. He also tried it with numerous lenses to ensure it wasn't a compatibility problem with any one specific lens.

• On the plus side, he said it makes a fantastic paper weight for a home office or photography studio. Although at $160, it seems like an expensive paper weight.
  

• The digital optic 3x telephoto conversion lens also works like a good pair of binoculars. When attached to your camera, it does allow you to see quite a long way away, when looking through the viewfinder. As long as you don't want to photograph what you're looking at.

Conclusion: At this time we cannot honestly recommend purchasing the Digital Optic 3x telephoto conversion camera lens.
