Thanks for all the responses guys. At least now I know I'm not the only one with a bad copy. Honestly though my 25mm 1.4 does a decent job when in CAF, moving focus slowly, and only when perspective is really changing fast does it hunt.

Oh well, I guess 45mm will not be used for videos.

I don't think you have a bad copy, I believe it's just a characteristic of the lens. Mine does the same thing. l also have seen reviews that say the 45 mm's video AF performance is not all that good.
