Strength:
Facilidad de uso.
Weakness:
Incompatibilidad con diferentes objetivos SIGMA.
Lo tengo desde hace 5 años y estoy bastante satisfecho con él, permite duplicar el rango focal sin un gasto excesivo Customer Service Gibraltar no dispone de servicio técnico de SIGMA y eso quizás sea una razón para comprarlo en España donde REFLECTA responde sin problemas y de una manera bastante eficaz.

Strength:
Optics, solid housing
Weakness:
fixation lenssystem in housing, tolerance bajonet 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. Customer Service not needed Similar Products Used: Sigma 1,4x APO converter (for Canon) excelent) Pentax 1,4x s converter excelent Takumar 2x converter cheap moderate optics |

Strength:
solid, good optics, cheap.
Weakness:
uuhh, none found yet. 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! Customer Service not used (just a good piece of workmanship) Similar Products Used: none |

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...
Weakness:
Ohh, nothing at all... 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... Customer Service No... Similar Products Used: Canon TC2x & TC1.4 |

Strength:
High speed autofocus with matched 70-200 2.8 lens. Good looks. Good construction.
Weakness:
Light loss. As with all converters light loss is a problem indoors Solid piece of equipment. This converter does all it claims. 8x10''s 400 speed fuji press film show no signs of weakness. Customer Service Great group to talk with on the phone. Have not had any problems with equipment yet. Similar Products Used: Nikon and Tamron converters. |

Strength:
EX finish
Weakness:
Result not sharp When I bought a new or used lense, I got a test for every aperture from wide to end. Before comment on a Sigma APO 2X, I would like to say it first that tested a Sigma 300 APO Macro f/4. The result was razor sharp from f/5.6~f/32. Customer Service N/A Similar Products Used: None |

Strength:
Allows for a natural extension of my Sigma 70-200 Ex
Weakness:
None I coupled this extender with my 70-200 and shot a local baseball game. THe prints were crisp and sharp. I was more than pleased with the results. I do not use the auto focus when shooting baseball, so I cannot comment on the speed in sports shooting, but, It seems fast on other general subjects. Customer Service not needed yet Similar Products Used: Only converter I own |
