sorry for the obtuse title. as some may know from my other thread, I'm looking seriously at going m43, having lived long enough without a good camera. so I'm comparing systems since I want this to be a long term relationship, and had pretty much decided that the compromises of m43 outweighed the compromises of the other formats. So at the ice rink tonight I'm just daydreaming along during the kiddie hockey practice when soccer/hockey mom (this is south Louisiana, mind you) pulls out the Canon 70-200 IS L. I of course put down the sudoku, duly pointed out the high-priced glass to my wife to soften her position when I finally make my commitment (see, I'm only spending HALF of what that lady had), and went over and had a nice talk with her. which shook my resolve on m43 and led me to some thoughts 1. since I started looking at m43, I've been a little concerned that none of the tele zooms are better than f/4 or so. I would most often use primes, I'm sure, but there are just times when there's no sub for the fast, long glass. fast ISO can help, but only so much. Have I missed one out there? or are people using adapters and /or just biding time until the lenses start showing up (I did see the thread on the rumored lenses, so maybe it is just a matter of time) 2. just for discussion, I was also wondering how many folks have done the "sold all my dx format stuff to convert" and never looked back. vs. those who are enthusiasts of m43, but still bring out the big guns when the time is right. --Marvin in Louisiana, still recovering from lens envy (well, I guess you never really recover, right?).
