For only $158, the TTArtisan AF 56mm f1.8 features 10 lens elements in 9 groups including 1 ultra-low dispersion element and 2 high-index glasses, which reduce dispersion and chromatic aberration and significantly improve the image quality.
Meyer-Optik Görlitz produced a series of triplet lenses “Trioplan“, based on the Cook Triplet design from 1893, in different focal lengths after WWII. With its new 100mm f/2.8, TTArtisan has come up with a lens very similar to it, both in look and optical design.
Optics manufacturer TTArtisan has announced a fully-manual 25mm F2 lens for APS-C mirrorless camera mounts that costs just $55. The lens is constructed of seven elements in five groups and offers a roughly 38mm full-frame equivalent focal length (except on Micro Four Thirds where it’s a 50mm equiv).
TTArtisan has announced a new 25mm f/2 lens for multiple APS-C mounts that costs a measly $55. The company says that it is the “best budget lens” and is making it available for Sony E, Fujifilm X, EOS-M, Micro Four Thirds, Canon RF, Nikon Z, and Leica L mounts and is claiming a massive 95% off sale that makes the lens a very affordable $55.
So far TTArtisan mostly released fast yet compact M-mount lenses, the most famous probably being their 50mm 0.95. These lenses often emphasized speed and size over sharpness, but now we are getting something different: the TTArtisan 35mm f/2.0 APO-ASPH.
