While I'm buying primes, I still would like to have a "reasonable" kit lens like my "L" 14-42. But I want the MSC focusing and the ability to use the MCON1, at the $99 price shipped at Cameta I just might get it for the quicker focus for video and the ability to use the MCON1. I tested my "L" at 14 against the Pany 14 and at 40 against the 40-150 and it was pretty close. Anyone actually own and compare the image quality of these two lenses? I see lots of references to R being better than the ED (both original and plastic mount version). I'm asking if folks think the R is significantly better optically than the "L". Thanks.
