Crazy test - Pansonic 20mm f/1.7 vs. Olympus 14-35mm f/2
Feb 27, 2012

Got to use the lens on E-PL3, all shots were shot in RAW using Photoshop to convert using same settings and WB (although it doesn't seem like that).

Photoshop corrects for m43 distortion which is significant on Panasonic 20mm 1.7

So, here's the test, using same exposure and aperture values, same processing, no CA correction.

100% crops are below the original image, left for 20mm, right for 14-35mm.
Top crops are from the center and bottom crops are side/corner.

f/2.8

f/4

f/5

f/4

f/2.8

f/4

Overall, results were pretty much what I had expected.

20mm performs quite well for such a small and compact lens but I don't like it's slow AF which wouldn't be a problem with a phase detect AF, but with contrast detect AF, even if the lens is focused it will search for focus while PDAF lens will "know" it's focused well and you'll be able to take the shot instantly.

However, the main problem of the lens is that it's neither here nor there.
Yes, IQ is pretty good (for a m43), but not wide open (except in the center).

This, along with harsh bokeh and quite deep DoF (for some reason much more DoF than on 14-35mm) makes is a bit weird.

Bokeh comparison - while perspecitve might be slightly different, the angle of view is almost the same so it's quite comparable.
