Sigma 50-150 f/2.8

[dakotah_jackson]

Have a 30D and am looking at this lens for being comparable to a 70-200 on the

EOS 3. Anyone have experience with how fast it autofocus is with it compared to

the 80-200 f/2.8 Canon lens?

 

I understand Sigma quality varies so am prepared to send back for a different

one if it the first or first few aren't quite up to snuff. Same as I have had to

do with a couple Canon lenses.

 

We are located where there are no stores with a four hour or longer drive

distance so getting to a shop to try one or more than one is not in the cards.

 

Thanks in advance.

The only weakness they found was in its close-focusing capabilities.

The speed is fine. The accuracy, however, leaves something to be desired. See Lightrules:

I owned that lens for while and used it on my 30D. I can't compare AF speed to the 80-200 but it was at least not much behind e.g. my 17-55/2.8. However the AF accuracy was not good enough for me, like so many other 50-150s it front-focused heavily at close distances, I had it calibrated, then it back-focused badly at farther distances, another calibration but still bad. Then I sold it cheap to someone who said he preferred manual focus anyway..
