One focal length, and usually the widest aperture the money buys · review
An $89 autofocus 50 mm f/1.8 for Sony full frame, at 156 grams, with no focus ring at all. Sold by TTArtisan, with 15 ratings so far.
At $89, TTArtisan’s 50mm Neo is the least expensive autofocus lens on this shelf. At 156 grams, it adds almost nothing to the camera.
It has no focus ring. TTArtisan pitches that as zero learning curve: point and shoot. Anyone who likes to fine-tune focus by hand should look elsewhere.
The glass-fiber composite shell is meant to take stickers, paint or a 3D-printed cover.
With 15 ratings at 4.0 stars, the listing is young.

There is no focus ring. TTArtisan designed it as a point-and-shoot lens; focus is by autofocus only.
TTArtisan says eye AF keeps subjects sharp, using the camera’s system.
Yes. An equivalent focal length is a calculation that describes the field of view on a full-frame camera; the engraved focal length never changes. On APS-C it frames like about 75 mm.
At $89, it is the 1 cheapest of the 8 models in this category published here.
