Hallo
Today I bought a sigma 17-50 2.8, very good stabilizes C100 image unfortunately does not work with one-shot AF as canon..
Has anyone experienced the Sigma 17-50 with C100?I tried a Tamron 17-55, fff noisy to stabilization,the sigma stabilizes nor hears .. works very well

Thanks

My Tamron 17-50 will focus 90% of the time and when it doesn't it will jump to wide open and fail to focus.

Thanks

I want to test Samyang 8mm and Samyang 85mm .. someone tested on c100?
