Pretty affordable solution in absence of long focal length lens
By AD
This is a very good solution if u dont want to spend $$ for long telephoto. This can be used on Digital SLR I use it with D80 one of the reviewer has mentioned mumbo jumbo written by Tamron which they have to because this is not designed for digital camera but that doesnt mean it can not be used. AF will work but will be slow and hunt so be prepared to do manual focusing. I use it for nature and wildlife photography and has clicked decent quality pictures with my skill level. I use it with Tamron 75-300 mm and this teleconverter makes it 600mm pretty decent range for the purpose of wildlife photography. It will slow down lens by 2 f stops so u will need very low shutter speeds or pretty good light.

In short it can be used effectively if you really know what you are doing and obviously something like this is difficult to use at 600 mm handheld so more often than not you will have to use tripod but when you compare the cost advantage it is a no brainer for a newbie or a hobbyist not wanting to spend too much.

4 starts because it is not a perfect solution but it is not even supposed to be so read it as 5 stars if you understand the limitations of this thing.

A lot of zoom for the buck
By B. L. Hutchinson
I use this 2x converter with a Nikon D-50, paired with the Nikkor 55-200mm lens made for that camera series, with 52mm lens diameter. Most notable pro -- This pair gives me 400mm zoom -- a single 400mm lens would cost $1000 and up. If you are trying to go from 200-400mm on a budget, i would recommend this lens. If you are doubling a 55mm lens, I'd recommend buying better glass. Important -- 1. you must shoot with a tripod, this doubler does not work with auto focus, and you can't possibly steady yourself enough to get tack sharp image. (Probably goes without saying on a long lens). 2. Practice a lot with focus before you go on vacation or where ever. The manual focus on my camera combination requires a very, very light touch to get tack sharp, especially with the depth of field that you will lose in f-stop. Best for well lighted situations.
