Today we're going to have a test of the new TTArtisan 50mm f2.0 full-frame lens. With 60mm x 35mm size and about 200g weight, It's a compact small lens even compared to an SD card. You can pocket this if you pair this lens up with the Sony A7C, it's going to be the most compact full-frame camera setup. Though it's not the fastest “nifty fifty” of the TTArtisan lenses, the standard focal length lens has a natural viewing angle and they say it has a fast enough aperture to provide high performance in low light.
Compare to Sony G Lenses
This TTArtisan 50mm f2.0 FF lens opens up from f16 to f2, they were able to get it down to f2 with this form factor, the lens does protrude out when you change the focus now the maximum size of this lens is very similar to those Sony G lenses, 24mm, 40mm and 50mm f2.8. The biggest difference is the Sony ones have auto focus, that's why the price range is so high up. But this TTArtisan lens is a manual lens that's why they could get the cost down to the minimum.
The optical design is 6 elements in 5 groups, including 2 high refraction index elements, which can effectively control spherical aberrations. Additionally, a 10-blade diaphragm is featured and contributes a smooth bokeh quality. But if you're changing your focus very fast, it's going to be really noticeable, if you slowly rack focus with this thing that can kind of hide it from the focus breathing issue. But other than that if you're using this for travel photography, street photography and even just travel content with videos as well you can get by with this TTArtisan little tiny compact setup.
Chromatic Aberration and Sharpness
You do get these purple fringing when you're really opening up the lens. This lens has decent sharpness expecially for the price point if you look at the middle sharpness, we're good to go, but around the corners, it does kind of distort a little bit. Honestly, I would bring this for my travels if I want a light setup.
The lens is designed to fit on multiple platforms, including DSLRs and mirrorless cameras like Sony E, Nikon Z, Fujifilm X, Canon M, and Micro Four-thirds, Leica L, and Canon RF mounts.
