Hi everyone! I usually carry a 65mm and 300mm with me when shooting 4x5. But on my last outing there were some shots that really needed a 150mm.
But I really dont have any room in my kit for another plasmat. What really small lenses are there that are still nice and sharp?
Thanks!
150 mm: Of all the focal lengths, 150mm offers the most options in lightweight lenses for 4x5 field photographers. Like the 135mm lenses mentioned above, most modern 150mm lenses are reasonably lightweight and compact. Since I have standardized around the 52mm filter size for my lightweight lenses, I would personally avoid the 150mm APO Symmar (58mm filters) and the 150mm Fujinon CM-W (67mm filters) when considering lenses specifically for backpacking (both make wonderful general purpose lenses, where the filter size becomes a non-issue). Also, like the 135mm lenses above, it might not make sense to have a dedicated lightweight lens in this focal length. Many of the current models are small enough and light enough to serve double duty for both backpacking and General Purpose use. The 150mm Rodenstock APO Sironar-S, for example is light enough (230g) and small enough (49mm filters) for backpacking, but has the very generous coverage (231mm image circle) and excellent performance desirable in a general purpose 150mm lens. If, however, you are seeking the lightest possible 150mm lens for backpacking, there are some choices that are even lighter (See Figure 2.). Here are some 150mm lenses I recommend when lightweight and compact size are the highest priorities:
