panasonic 14mm f2.5

Hi What is the difference between the panasonic 14mm f2.5 and the newer 14mm f2.5ii . You can buy the mark i version for a lot less  . Is it worth the extra money for the mark 2 . Thanks  Ian

I believe it is the same lens internally but the new 14 and 20mm (mk2's) are of metal construction and other cosmetic changes.

As the others have said, absolutely Buggerall of any consequence , unless you desperately need a Panasonic GM1 to sit straight on the desk with it on (the Mk1 is a bit larger so it tilts the cam)

There is a bit of sample variation with the 14mm F2.5, mine is very sharp wideopen edge to edge , in fact the edges are a lot better than any of the 20mm F1.7s I`ve owned (about 4 over the years) both lenses wideopen and just as good both set at F2.8 !! . I find Focus accuracy is better than the 20mm too and considerably faster . The lens isn`t as sharp as the 20mm overall but its damn sharp enough .

This is an underrated lens, it makes the GM1 into a true pocket compact .. prob is that both the Panny 12-32 Pancake zoom and even more so the 14-42-IIHD are almost as good wideopen , and although almost a stop slower , they do have OIS ......

I find the 14 F2.5 more at home on Olympus bodies which have IBIS , it makes a fantastic Bodycap for the EM1

Thanks for your replies . I have a panny gx7 with the 14-42 lens . I may just stick with it or maybe 154mm f2.5 version 1
