>My question relates to the Panasonic 12-35mm >lens. What's been the reaction to it by users here? Thanks, >Richard
I do not believe that there are a large number of members posting here who have shot with this lens. I am also active on another forum that specializes in m4/3rd's equipment, and there is not as much user feedback on this lens as there is on others. The primary complaint that is often voiced is the price of the lens, or not enough additional IQ for the additional cost of the lens. I have not heard too many complaints about the overall IQ, so I take that as a good sign. I would love to purchase this lens, but my wallet is tapped out at the moment.
I think that you might find this review useful: http://www.lensrentals.com/blog/2012/06/a-weekend-with-the-panasonic-12-35-f2-8 . Roger is quite the character, but he seems to be a straight shooter (pun intended) with his blog. I am a bit more suspect of some of the other usual suspects, who shall not be named, that have "reviewed" this lens, so take their opinions with a grain of salt if you are not familiar with their writings.
