Comparison – 7artisans 12mm F2.8 vs Rokinon 12mm F2

Rokinon 12mm F2 SC is about 1/2 times more expensive, however it’s massively available on the used lens market. I’ve purchased my sample used for the price of new 7artisans 12mm F2.8.

It has huge lens hood and quite wide front lens body area. Focus ring position is same, but 7artisans has more comfortable aperture ring location closer to camera. That is also reducing the chance to accidentally change aperture because it’s click-less, while Rokinon aperture has half-stop clicks.



View from the front makes Rokinon significantly bigger. Fortunately hood can be removed, but camera still can’t be put on the flat surfacelike with 7artisans 12mm F2.8 lens.


Test shots at same aperture values

Test shots are made on Fuji X-Pro2 from same tripod point. I’ve initially noticed different color tint from both lens, so set WB to constant 6300K for all shots.

Brief Conclusions

Most results are quite expected taking into account more advanced optical formula and glass quality of Rokinon (Samyang) 12mm F2 SC lens.

Rokinon 12mm F2 pros:

  • Rokinon 12mm F2 actual angle is noticeably wider than 7artisans 12mm F2.8
  • It is collecting more light (lower ISO on same Shutter speed + Aperture), which is probably result of better coating
  • Border and corner sharpness is significantly higher starting at F2.8, thankfully to Hybrid-Aspherical, Aspherical and ED elements.
  • It has wider F2 aperture
  • Lens hood cuts side light better
  • Filters can be applied directly
  • Aperture has click-stops

7artisans 12mm F2.8 pros:

  • Lens front area is noticebly smaller and more compact (but you will need adapter to attach Polarizer or other filter)
  • It’s more discrete lens for street shooting
  • It’s almost 1/2 times cheaper
  • Aperture is click-less which is nice for video


    • Yes, 7Ardisans made quite good 12mm for it’s price. Of course Rokinon 12mm is more advanced optically (and so more expensive), I’d say it’s already a classic ultrawide for modern mirrorless. And 7Artisans 12mm is good more affordable alternative to keep the overall budget lower.
