Panny 20mm/1.7 vs. Leica 15mm/1.7 vs. Oly 17/1.7
2 months ago

I'm looking at a 35mm FF equivalent lens for my GH4 and looking at the 20($428), 15mm($597), 17mm($499, $399 on sale recently) lenses from Panny, Oly and Panleica.

While I really like the solid build of the Olympus lenses(especially the manual focus clutch mechanism) I would like to see if anyone got this over the two other lenses (15mm & Oly 17) and why.

Pros/cons?

How fast is the AF on the new Panny 20 v2?. I tried the Olympus yesterday and it is on sale used for $390. The af was pretty fast. I haven't tried the Leica 15mm.
