So I assume this isn't the best lens to utilize for any type of landscape photos? I took some pics tonight and they came out like a painting instead of a picture. I would have used my other lens but didn't have it on me at the time. I tried closing the F stop to like f11 because i wanted more depth of field to get everything in focus but results weren't too good. Any help would be appreciated. thx!

You may want to post this question (include a copy of the photo, too) to the Micro Four Thirds forum. I am sure you can get the problem figured out with some help there.

I was just doing a lens hub search, and came across this lens... it sounded pretty good! I was just about to consider buying a GX1 for my daughter just so I can get this f/1.4 lens but with your feedback I don't know now.

For landscape, perhaps you may like to consider a wider angle lens, that is more designed for that?

I don't know if they are any good, but these came up during my search, and would be more appropriate (or at least come close) for landscape:

http://www.dpreview.com/products/olympus/lenses/olympus_m_17_2p8
http://www.dpreview.com/products/panasonic/lenses/panasonic_20_1p7
or even this zoom lens http://www.dpreview.com/products/panasonic/lenses/panasonic_x_12-35_2p8/specification

Do keep in mind that the relative focal length is x2 for MFT... so a 19mm is similar to a FF 38mm... you can definitely use wider for landscape. (I just wish they would start quoting in viewing angle in addition to focal length)
