I have just bought Toyo 45AX field camera and got Rodenstock 210mm S lens. For I like to shoot landscape pictures, I would like to buy a 90mm lens. Somebody men tioned on your Web Page that the Nikon f8 90mm is the best. However, the Rodenst ock has f5.6 90mm lens. John Fielder mentioned that the large f will be his bett er choice in his book. Would you please let me know your choice regarding the sh arpness and color contrasty. Thanks! Yong-ran Zhu

I believe the sharpness and contrast of both lenses would be equivalent. What yo u get with f5.6 is a lens which is easier to focus, due to brighter image and shallower dof at focussing aperture. You pay for it in terms of $$, size, and weight. For the latter reasons, for field work I chose the f8 lens. Most of the f8 lenses give you a significantly smaller image circle than a f5.6 lens, except for the nikon, hence the recommendation you read.
