Sigma Launches the 120-300mm F2.8 DG OS HSM

[sharky620ti]

I had the previous 120-300 OS (the one launched in 2011) and is was quite possiby the worst lens I have ever used so I sold it after just 8 months. The image quality was awful and unusable with both 1.4 and 2X converters. I went back to sigma twice for a slipping focus ring during the time I owned it. I think sigma are charging too much for this new lens if its essentially the same lens with just user adjustability added.

There are many mixed experiences with this lens,

The first version and the second one(with os), mixed experiences from users who either love it or hate,
Sending them back for failing os/auto focus..
Some find it amazingly sharp, others unacceptable(especially with TC's)

Yet there are a lot of reviews who see this as a serieus alternative to a 300 f2.8 from canon/nikon,
Or an extended 70-200 2.8

Photozone.de was quite positive, especially on center performence (and on crop factor bodies.)


I have also read about thedigitalpicture mid frame and corner results being a bit colored, by the fact that it should perform better when used at a different distance then it was tested.
Anyone that can confirm this?,




If they keep their word at sigma about the quality control, this lens would be a great alternative to the canon 70-200 when used on a crop factor body

Hope to see some thorough reviews when the lens gets released, with real world (high res) examples and crops
