Hello, I have M.zuiko 12/2 and Panasonic 20mm. I want wider than 12mm. I can't afford 7-14 but i found someone whom want to trade his M.zuiko 9-18 and interested by my 20/1.7 version II. It could be a good deal, what do you think? Then i can sell my M.zuiko 12/2 for to buy a Leica 25/1.4. The M.zuiko can up to 18mm even if aperture is f/5.6. So from M.zuiko 12/2 and Panasonic 20/1.7 to M.zuiko 9-18 + Leica 25/1.4 The cons with M.zuiko 9-18 versus M.zuiko 12/2: -Bigger than M.zuiko 12/2 -less shaper than M.zuiko 12/2 -less lighter The cons with Leica 25/1.4 versus Panasonic 20/1.7: -Bigger than Panasonic 20/1.7 -less sharper than Panasonic 20/1.7 at f/1.7 and f/2 What do you think? Trade my Panasonic 20/1.7 II for the M.zuiko 9-18, is it a good deal? Thank you.
