Very preliminary thoughts on the 40-150 F2.8

Re: Slow to focus, but I love it.

I can only respond as an E-M1 user but will suggest turning face detection off, or pairing it with CAF.  My hunch is the feature takes a lot of processing power and I limit its use to very shallow DOFs when my movement and the subject's movement make it difficult to reliably achieve focus. E-M1 uses hybrid focus in CAF and is different from other bodies, but I don't find SAF slower.

Other lenses I have in the Pro's FL range include the kit 40-150, 75,, 50-200 HG, 35-100 and 150 SHGs and the Pro is significantly faster than the lot.

Cheers,

Rick
