And btw there is nothing wrong with pancakes, they are good optics - not L lenses but good nevertheless - I would rate my Pana 20mm as on par with my Nikon 35mm 1.8 and a bit better than the Canon 35mm f2 (on APS-C). And much better than the DSLR kit lenses.
Not sure what you are smoking: Panasonic 20 f/1.8 vs Nikon 35 f/1.8 vs Canon 35 f/2. The last being a FF lens on APS-C mount EASILY beats out the rest in terms of optical quality... unless you have a bad copy (do you even own a Canon camera)?
Have you actually read the links that you posted? I was talking based on my actual experience having used all three of the lenses extensively. However the photozone tests that you posted are also in agreement with what I said.
Looking at the results the Panasonic is already excellent wide open at f1.7 with a center resolution of 2462 and border of 2059. Here is what your link says about the 20mm 1.7: \"The center performance is nothing short of stellar straight from f/1.7 till at least f/5.6. If you\'d really like to see the breathtaking resolution of the Panasonic sensor of the G-series this is the lens to choose at this stage. The border/corner quality isn\'t quite on that level but still very good.\"
Comparable apertures - Canon 35mm vs Panasonic 20mm:
canon 35mm: center 2352, border 2130
Pana 20mm: center 2515, border 2132
And this is despite the fact that the 35mm f2 is getting the advantage of a higher resolution sensor (15 MP) compared to the 12MP sensor used for the panasonic tests. If you compare at equal sensor resolutions then the 35mm f2 will be even lower.
Even at f4 the canon 35mm barely catches up to the center resolution of the panasonic at f1.7! and passes ahead of the panasonic on border resolution (2205 vs 2082). And again thats with a higher resolution sensor. Try a website like slrgear which normalizes out the sensor resolution and you will see even more clearly the pana 20mm performs better than the canon 35mm at most apertures (specially at large apertures). Plus there are other aspects like contrast, where I found the pancake to be better. The only major flaw for the pancake is the higher vignetting, but then the canon isn\'t much better either.
Anyways, we have gone rather off topic. I don\'t want to create a thread within a thread, so I just leave it at that.
