The performance here reminds me a lot of the 7Artisans 28mm 1.4, which is good news. Therefore – stopped down to f/5.6 to f/8.0 – the lens is also a good choice for landscape or architecture infinity shooting, this is rare among small yet fast M-mount lenses. Midframe and corners are nothing to write home about at wider apertures, but from f/4.0 onwards the across frame performance is very even. Sharpness infinity (42mp Sony A7rII)Īt infinity the TTArtisan 50mm 1.4 is a bit soft at the maximum aperture even in the center, but this improves significantly on stopping down to f/2.0. The focus distance was 0.7 m and you may get slightly different results at other distances. I did not shoot both lenses side by side, if I did the circles from the f/1.2 lens would be bigger in direct comparison. You can clearly see some onion ring structures caused by the use of aspherical elements though, these are still noticeable with the E-mount version. I consider this performance average for a lens with these parameters. So in the following comparison we move from the center (left) to the extreme corner (right) and see how the shape of the light circle changes.įor comparison’s sake I included the Voigtlander 50mm 1.2 here. In the center of the frame almost every lens will render a perfect circle, but only lenses with very low optical vignetting will keep this shape in the corners. Without going too much into technical details optical vignetting leads to the truncation of light circles towards the borders of the frame. Very fast yet compact lenses usually show a significant amount of optical vignetting. It is recommended to have a look at this article first to get an idea how this brightness graph works. Stopped down these values are comparable to other small yet fast 50mm lenses like the Voigtlander 50mm 1.2 Nokton, at wider apertures the TTArtisan lens is slightly better (by about ~0.3 EV). Wide open there is strong light falloff of roughly 2.7 EV in the extreme corners, stopped down to f/2.0 this improves to 1.9 EV, stopped down to f/2.8 it is 1.4 EV and further improves to 1.3 EV at f/8.0. There is again no hood included in the package and the lens also does not feature electronic contacts to communicate with your camera. The aperture ring has equidistant and very distinct half-stop click stops and feels very tightly assembled. There is no focus tab like on the M-mount version. Markings are yellow/white (engraved and filled with paint), the focus ring has a nice albeit not perfectly even resistance and turns about 160° from the minimum focus distance of 0.5 m to infinity. Handling / Build Quality TTArtisan 50mm 1.4 Eįrom the outer apperance the new E-mount version looks even more like a Leica M lens than the M-mount version due to using fonts more closely resembling the Leica ones. The TTArtisan 50mm 1.4 E was kindly provided free of charge by TTArtisan for reviewing purpose for a duration of 4 weeks. You can usually buy this lens from the manufacturer’s shop, on /, B&H or / for about $235 (affiliate links) Maximum Magnification: 1:7.7 (measured).Number of Aperture Blades: 12 (straight).Notable changes: 30g heavier and minimum focus distance 0.5 m instead of 0.7 m. The new E-mount version is very similar to the M-mount version. portrait distance 2.0m distance (24mp Sony A7III).
