Both tele-extenders have 0.75 magification, which gives an 35mm equivalent of a 28.5mm lens. My main impression is the Kenko gives a slighty softer image, but that the Tiffen is useless unless you use it at full wide angle. I am rather disappointed in the Tiffen, since I had read good reviews about the Megaplus. I got the Tiffen at Circuit City, and it does not have the branding Megaplus, so I don't know if they are different lenses or not. It is possible the Circuit City lens is an inferior lens, and the real Megaplus is much better.
The specs of the two lenses are:
| Lens | Front Thread | Rear Thread | Magnification | Location Purchased |
|---|---|---|---|---|
| Kenko KNW-075 | 52mm | 67mm | 0.75x | Hunts camera in Melrose, MA |
| Tiffen 43 | 43mm | 67mm | 0.75x | Circuit City |
