The TTArtisan 50mm f/1.4 ASPH is a manual lens suited for camera sensors up to 60 megapixels (MP) that adopts an optical structure of ten elements in eight groups and twelve diaphragm blades using an advanced optical design. The lens uses a series of specialized elements to help reduce aberrations and distortion so that it can deliver a sharper and more accurate image. This design consists of one aspherical element, one abnormal dispersion element, and eight high index elements.

The new TTArtisan 50mm F1.4 ASPH lens is entirely manual and, according to TTArtisan, able to be used with sensors up to 60MP. The optical construction consists of ten elements in eight groups, including a low-dispersion element and aspherical element.
It uses a 12-blade aperture diaphragm, has an aperture range of F1.4 through F16, offers a minimum focusing distance of 50cm (19.7”) and uses a 49mm front filter thread.
As with TTArtisan’s recent lenses, this one follows a clearly Leica-inspired design, complete with white and yellow markings in a Leica-like typeface. The lens features a clicked aperture ring and is rather compact. The lens measures 68mm (2.68”) long, 57mm (2.24”) in diameter and weighs around 430g (15.2oz), with slight variations between the different mounts.

How good is TTArtisan?
The company claims that the 50mm standard focal length is best suited for portrait photography since it says there will be very little distortion or compression in the frame. Additionaly, TTArtisan says that the lens should be useful for getting up-close “detail” shots due to the lenses wide open f/1.4 aperture; It says is great separation with the bokeh. Additionally, the fast wide-open aperture will work great for low-light situations.
The lens has a minimum focusing distance of 0.5 meters (19.7 inches), an aperture range of f/1.4 to f/16, a field of view of 45 degrees, a 49mm filter thread, and weighs between 429 to 459 grams depending on the lens mount version.
Externally, the design looks strikingly similar to many existing Leica optics.
