The TTArtisan 21mm F1.5 ASPH is the second lens I’ve reviewed from Chinese lensmaker TTArtisan.  The first was an 11mm F2.8 Fisheye lens, which is hardly a conventional lens.  That lens was good enough, however, that I was open to testing another TTArtisan lens.  A 21mm F1.5 lens is slightly more conventional, though the maximum aperture designation of 1.5 is something I tend to see more with cine lenses that are measured in T-stops; an aperture value of F1.4 is typically the standard for stills lenses.  While a maximum aperture of F1.5 is rare, rarer still is a wide aperture, wide angle prime for full frame cameras that costs less than $250 USD.

The TTArtisan 21mm is available in Leica L-mount (black and silver), M-mount (ditt0), Sony E-mount, Canon RF-mount, and Nikon Z-mount, so it covers most of the bases of the major modern mirrorless cameras.  It is a fully manual lens (manual focus, manual aperture, and no electronics), so developing for multiple mounts is much simpler.  I’ve done my review in a Canon RF mount and on my 45MP Canon EOS R5.  Typically the R5 is a great platform for manual focus, as its innovative Focus Guide works well and the in-body-image-stabilization helps deliver good results in a variety of settings.  The lack of electronics in the TTArtisan 21mm means that the Focus Guide doesn’t work, however, so I’m left with more traditional focus overlays and magnifying the image…which is still a far cry simpler than manual focus on any DSLR!

So is this a lens worth considering?  That really comes down to your tastes, and perhaps these images will help you decide. If you would prefer to watch your reviews, you can watch the video review or check out my full text review.

Thanks to TTArtisan for sending me a loaner copy of the lens for review.  This (as always) is a completely independent review.
