<p>I live in sunny Florida and shoot 1/2000 all the time with a gaggle of Leicaflex SL's (4) w/o any exposure problems. The SL2, however, does have documented issues with higher shutter speeds, but I don't know if it is a design defect as some say or an issue with the oils used on earlier ones as other repair guys tell me. I had a SL2 when I first got into Leicaflex, and didn't notice any issues, but really didn't use the camera must, because at the time I had an SL and used that camera much, much, much more. The SL is the only camera I've used where taking the picture is as much fun as getting the picture. I've used a lot of mechanical cameras over the decades, and the SL is not only my favorite Leica (along with the M5), but it is my favorite SLR from all makers.<br>
The SL -- as probably all the Leicaflex -- has this great braking system which allows them to be shot at low, low shutter speeds w/o visible shake. I figure they give an extra stop or two of speed compared to the R cameras or SLRs from other makers. Pretty cool. And the viewfinder is one of the best. Can't say enough about these cameras. It's the camera that made me largely give up rangefinders. </p>
