I look to buy a double coated (perferred) or at least single coated lens within the stated size limit and under F6.8. My current 135 Optar isn't coated and I wo uld like to improve on it's performance. I shoot both B&W and color positive fil m. I plan on using the lens on both my 2x3 and 4x5. (the 2x3 wil take a #1 board ) I would like to stay under $475. I see quite a few lenses in Shutterbug around the size I need and around F5.6, as well as a new Xenar lens from Schneider, bu t would like a rec from shooters before I go forward. My cameras prevent much ar chitectural shooting due to movements (front only) but some leeway in shooting t he 4x5 would be nice. Common subjects are street shooting and flowers with the 2 x3 and landscapes with the 4x5. My aim is for better color performance.
