I've owned the 24 for a while now and consider it an outstanding lens. For no particularly good reason I've decided to buy the 28 Cron and see if I like it better. I'd guess few folks keep both these lenses in their kit and was wondering which you prefer and why. As I've mentioned in another thread, I haven't had much luck shooting wide open with the luxes (which was my initial motivation in getting into the M system). This is mostly my fault (can't see well enough to focus in low light) but also in part because the lenses back-focused and I've lost confidence in (or maybe patience with) Leica to adjust them properly. Appreciate any comments that might help in my never ending quest to fall in love with this system
