I need help from you experts again. I'm thinking to get a P&S for those times when I don't feel like carrying a RF even though I have compact camera CL. A friend of mine has a Mini II and the pictures look great in both color and B&W. So I'm thinking to get one for myself but I noticed that there were 3 models made. I search photo.net and everywhere else on the web but there's no detail description or comparison of these 3 models. Can someone tell me what the differences are between the 3 in features/functions, built quality, lens quality, etc.? Also, any suggestion on which one I should get? Or does it matter much which one I get? I'm pretty sure that Mini I & II has Elmar lens where as III has Summar (what's Summar?). I appreciate any insights or experience anyone might have. As always, thank you for contributions.
