Review on Zeiss Normal Sonnar Rangefinder Cameras by Valerie Perrien

Got mine in October 2015 and it's exceptional. This is a great complement to the 50mm Leica Elmar lens as the two lenses have different personalities and uses. I had no trouble focusing with the M9. It focuses great at all apertures, but requires technical understanding. Created around 1930 (see Wikipedia for details), it is always very sharp in the center even at f/1.5, considering that the depth of field at a distance of 0.9 m is only 3 mm. Extreme care must be taken when decentering a subject at f/1.5 with a rangefinder. This lens is ideal for all live view mirrorless camera systems, with an adapter of course, as focusing is never a problem for such devices that use focus. Dive. Do a lot of research first, don't always trust the reviews. I think those who talk about focus shift ruining photos are using the lens in the wrong situation. If you can't understand the optical design of this lens, you might be better off looking at the new Cosina Voigtlaender lens, which has similar specs and is less technical for the user. or isolates objects in near-field landscapes. Standard landscapes are best captured with apertures f5.6 - f16.
