Here are some very basic comparisons of size/weight/aperture and compatibility with a TS mount for Cambo:
Tech Camera OverviewAs Paul says there is no "universal recommendation" for landscape. If there were that list of available lenses would be a lot shorter! His questions are an excellent way to help pin down your wants/needs.
In general my favorite tech camera lenses are:
120ASPH
90HR-SW
60XL
32HR
All of these lenses are quite pricey, but they are all incredibly good optically, have large image circles, have good compatibility with a broad range of digital backs including the 80mp generation, and are easy to work with. But I would be the first to say that a 32HR is not the "best bang for your buck" kind of lens. It's the premium lens.
If you're not using a 80mp digital back the 35XL and 47XL are both very good value - very good quality, reasonable price.
In
general (see the previous link for more extensive comparisons) a Schneider lens is lighter, smaller, and cheaper, with a larger stated image circle for which some is not usable, but with greater fall off, more often calls for a center filter, and produces more color cast issues, especially with high res backs. In general a Rodenstock lens is heavier, larger, more expensive, has a smaller image circle for which nearly all is usable, and with less fall off with less call for a center filter, and produces less color cast issues.
