Re: question about focusing speed of the sony 135 1.8

CZ 135/1.8 has rear focusing gear so in theory it should be fast. I have this lens and I use it far more often than Sony 70-200/2.8 SSM simply because its a whole stop brighter than f2.8 and image is totally useable (sharp!) at wide aperture, thus give me much needed shutter speed. But it's not blazing fast in terms of AF speed (CZ 24-70 is truly fast). I won't use it for sports tracking or BIF. It's fast enough for street, event, wedding, portraiture, etc.
