The 7artisans 12mm F2.8 II features a 100-degree wide angle of view, which is an all-manual lens well-suited for landscape, interior, and architectural subjects requiring a broad field of view.
Bright Aperture: Bright f/2.8 maximum aperture suits working in a variety of lighting conditions and also contributes to the sleek form factor.
The 5-blade diaphragm contributes to a smooth and pleasing bokeh quality.
What I can tell you today, this are the best build lenses I ever had in my hands. No focus breathing and the run of the focus and aperture ring is a dream…
Down below you can see some images he shared as well as the lens specs:
APS-C Format Lens: The 7artisans 25mm F0.95 lens is designed for use with Fuji X-mount mirrorless digital cameras, providing a 37.5mm equivalent focal length. It is well-suited to everyday shooting with subjects including portraiture, street, nightscape, landscape, and reportage.
Optical Design: Its optical system consists of 11 elements in 9 groups, which including 3 HOYA ultra-Low dispersion elements to improve contrast and colour rendering in a variety of lighting conditions.
Ideal Aperture: A fast f/0.95 maximum aperture suits working in low-light conditions and also offers great control over the depth of field. A 13-blade diaphragm contributes a pleasing out-of-focus quality when working with selective focus techniques.
All-metal Construction: The all-metal lens barrel features an engraved depth of field and focuses scales. Additionally, a metal lens mount also offers increased durability between the lens and camera.
Multi-layer Coating: The multi-layer coating has been applied to individual elements and reduces flare and ghosting in order to produce greater contrast and colour accuracy when working in strong lighting conditions.
Now also Christopher Frost made the very same comparison, but will he also get to the same conclusions?
all very similar build quality. All made of metal
all focus rings are precise enough for accurate focusing at f/0.95, although the Laowa turns round further, which can be helpful
all manual focus, no IBIS, no EXIF transmitted to camera
the Laowa Argus is bigger and heavier than the other two lenses
at f/0.95 all three lenses are surprisingly sharp in the middle, but none of them has impressive contrast
at f/0.95 the 7Artisans shows quite strong color cast and some magenta color fringing
at f/0.95 the Mitakon as some purple fringing
at f/0.95 the Laowa Argus shows a bit less color fringing than the other two
in the corners the Mitakon is by far the softest followed by the 7Artisans while the Venus Optics Laowa lens remains surprisingly sharp
at f/1.4 all lenses remain sharp as before in the corners, while in the middle they gain a lot of contrast and look a little sharper than before with the Laowa Argus being still noticeably ahead of the other two
at f/2 all three lenses look virtually perfect in the center. In the corners the situation is the same as in the wide apertures
at f/4 all three lenses enjoy a nice improvement in corner sharpness with the Laowa being ahead of the others
af f/11 diffraction kicks in
vignetting and distortion: all three lenses have a remarkably similar performance. They show just a little barrel distortion af f/0.95
the Mitakon seems to show the least vignetting at f/0.95 and the Laowa Argus the most
at f/2 the vignetting is gone on the 7Artisans and Mitakon, but it remains a bit on the Laowa
close up focus at f/0.95: Mitakon is the softest, the 7Artisans is sharp but with terrible contrast, the Laowa is pretty sharp with a bit of color fringing
at f/1.4 the Mitakon begins to look sharper and the 7Artisans gains contrast, and the Laowa looks the sharpest
af f/2 all gain sharpness, although the 7Artisans still suffers from lower contrast
against bright light sources, they all show tons of intrusive flare with the Mitakon looking a bit worse than the others
Bokeh: on the 7Artisans is fine but can be a bit nervous and also show a little colorful outlining. Background bokeh on Mitakon and Laowa is exceptionally soft and smooth. The Mitakon suffers a bit of longitudinal chromatic aberration.
Conclusions:
7Artisans typical low budget model that can give some gorgeous narrow depth of field image
the Mitakon is more expensive than the 7Artisans. He liked it a lot when it came out, but it’s the oldest of the three and now shows its age
if you want to spend more for the lens than for the 7Artisans, go for the Laowa, as it is sharper and better in every way over the Mitakon, except for vignetting
