Strengths:    Optics, solid housing

Weaknesses:    fixation lenssystem in housing,
tolerance bajonet

Bottom Line:   
Good optical performance and rather cheap compared to the originals (Canon, Pentax)
The bajonet fits to thight to my Canon lens, the bajonet of the lens doesn't fit so thight to te camera anymore. The lenssystem came out of the housing(due to vibrations?)it was simply repairable by myself, so this was a minor problem.

Strengths:    solid, good optics, cheap.

Weaknesses:    uuhh, none found yet.

Bottom Line:   
I needed some extention for my (yes, also) 70-200 EX HSM. This TC is just what I needed. I used it in Greece and I shot some really nice pictures (slides) of buildings and my girlfriend. Autofocus works perfect on my eos300 and I found very little vignetting at 5,6. IT's a perfect TC!

Strengths:    Cheap, it's great with Sigma 70-200, mega good combo... The Sigma TC2x makes the lens super duper... Our get at little bag for it...

Weaknesses:    Ohh, nothing at all...

Bottom Line:   
Great TC, wery good build...
When i use it on my Sigma 70-200 it is great, nearly no loose of sharpness and speed... This is a killer combo, wouldn't use this TC with other then EX telelensen, it's not build to be used with reguler lenses...
Great for nature, sports and all the things that you need a 400mm lens for...
Man I love it...

Strengths:    High speed autofocus with matched 70-200 2.8 lens. Good looks. Good construction.

Weaknesses:    Light loss. As with all converters light loss is a problem indoors

Bottom Line:   
Solid piece of equipment. This converter does all it claims. 8x10's 400 speed fuji press film show no signs of weakness.
