I need advice regarding the purchase of a 180mm lens. I intend to use the lens primarily for landscape work, and shoot both color and black and white. I own a Schneider XL 110mm, and intend to ultimately purchase a wide angle (72, 75 or 80mm) as well as a Nikon 300mm.
My dilemna is as follows: The relative merits of modern lenses in the 180mm length is not addressed often. I have located a demo 180mm Caltar II for a little over $400, which apparently has not been used. I have also located 2 mint Apo-Symmar 180mm which can each be purchased for just under $700. Another retailer has an Apo-Sironar S 180mm for about $750. Finally, I can simply purchase a new Apo-Symmar L or Apo-Sironar S, for just under $1000 and $1050, respectively.
I intend to use the 180mm as my normal lens, along with the SS XL 110mm. Because I shoot color, I prefer lenses of similar color temperature, which is why I am not considering a Nikon or Fuji. Lens sharpness is of paramount concern.
Your advice and thoughts?
