The title just about sums it up. I'm looking for an inexpensive lens for 4x5 nature/landscape photography in the 200-215mm range with B&W film and chromes. I will be doing some hiking so a lightweight lens would be a plus. Another plus would be coverage for 5x7, if I ever take that leap The other lens I've been thinking about is the 210mm Caltar II-E. It seems the 203mm Ektar is sharpest wide open but I'm going to have to stop down for depth of field-will that cause significant image degradation at lets say f16 or 22?
