[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]Ted, I appreciate the tip. I will certainly give it a try at my next opportunity. The Leica-R lenses are a great value, and I look forward making them work for me. On the Oly 4/3 system, the 28 is very close to being a normal FL, but the DOF and focusing still have the WA characteristics.
