Actually I don't quite understand your question, when you say "what's the big deal?". The big deal is: A near focusing lens focuses near, contrary to a non near focussing lens which doesn't. The secret is: If you want to focus closer to an object, you use a close focusing lens, if you don't, then you don't need to use a close focusing lens. The reason it is (was) more expensive than its normal counter part, are " 1.) The focussing mechanism on the lens barrel is more complicated 2.) It uses a set of clip on extra eyes when using close focus. This of course also costs money to produce. I own a DR Summicron. Quite a few times, the close focussing facility helped me getting the picture I wanted. I just wish there was an even closer focussing lens for the M's (not the Visioflex) available. However I suppose the parallax correction would be to complicated to do this. I find this lens most useful. The quality is also very good. Regards, Horst schmidt
