Product Information

TTArtisans ( different from 7artisans) currently has three lenses for Leica M-mount and a new 50mm f/0.95 lens coming soon. There is a small built-in lens hood, but a lens of this type cannot accommodate screw-on filters or filter holders. With some care, I found it was possible to hand-hold a 100mm square StarGlow filter in front of the lens to add a soft focus effect to stars.

So instead of pre-focusing, I had to take advantage of the Leica M10-P’s zoom and focus peaking – this was fine, but it slowed me down, which isn’t ideal when your about 20cm from someone else’s face. This all said, everyone seemed to get on board with how I was entertaining myself making their faces look all distorted and weird. Conventional portraiture this certain is not, but I am more than pleased with the outcome. My final shot of the outing was shooting up into this tree. I’d been shooting with the add-on Visoflex viewfinder and whilst up until this point I had found its articulation useful, I’d not found it essential. For this particular shot, the fact that the Visoflex articulates 90 degrees upward was very useful indeed. I held the camera in front of me pointing directly upward and yet was able to shoot with my eye to the viewfinder with comfort. This is only the second fisheye lens being reviewed here, so it might make sense to have a short look what differentiates a fisheye lens from a normal ultra wide angle lens. Most of this section is taken from my TTArtisan 11mm 2.8 Fisheye review.Open full-size image in new tab. Same image at f/4.5 with 200% zoomed-in crop boxes showing star performance. Not much improvement to stars over f/4. Open full-size image in new tab. 4 min. single exposure at f/5.6, ISO 1600, Canon EOS Ra, Bortle 3 sky. I haven’t used this one. In terms of weight and size it sits inbetween the aforementioned TTArtisan and this AstrHori. The AstrHori 12mm 2.8 Fisheye was kindly provided free of charge by AstrHori for reviewing purpose for a few weeks. What is a fisheye lens? Une projection rectilinéaire classique comme avec un profil de correction Lightroom supprimera environ 30% de l’image et déformera les sujets près des bords.

As long as you can keep the horizon flat, and keep focus in the centre of the frame, this lens is sharp. The edge of the frame is fraught with softness, colour smears, and vignetting, but nothing that a little stopping down doesn’t mostly fix. And, nothing that users of ultra wide angle lenses aren’t used to anyway. As shown in the example above it is also possible to defish fisheye pictures. Defishing means removing the typical fisheye distortion in post. Here the image is stretched so much, the resulting image quality leaves a lot to be desired. If you want straight lines in your pictures better get a rectilinear ultra wide angle lens in the first place. Handling / Build Quality AstrHori 12mm 2.8 Fisheye At 440g the TTArtisan lens is much lighter and also smaller. It looses when it comes to flare resistance and CA correction, but performs similar in terms of sharpness and coma correction. The situation is not as bad as it is with many other M-mount ultra wide angle lenses (see this article for further reference) though, so it can still be an option if you are looking for a most compact fisheye lens or you only intend to shoot stopped down or at closer distances.

Now I must admit, I’m not particularly into fisheye photography. Nor is a fisheye lens the first type of lens that I think of as being particularly compatible with Leica rangefinder cameras – especially if said fisheye doesn’t come with a viewfinder. In fact, to a degree, I do (or at least did) slightly question the sense of making a fisheye lens for m-mount cameras at all. Open full-size image in new tab. Same image at f/3.5 with 200% zoomed-in crop boxes showing star performance. Huge improvement in sharpness of stars in corners/edge. Still some chromatic abberation and coma, but not obtrusive. Open full-size image in new tab. 2 min. single exposure at f/4, ISO 1600, Canon EOS Ra, Bortle 3 sky. The Fisheye-Hemi Plug-In automaticaly remaps your fisheye images to minimize distortion and maximize the preservation of all image details. Chromatic Aberration: Longitudinal CA is low, lower than I would have expected. This is good news, because makes the lateral CA you'll clearly see at wide apertures easily correctable. Flare: Decent if the light source is somewhat centrally located. Put the light source towards a corner, though, and things get really complex, with everything from prisming to colored ghosting occurring.

While Artisans’s 35/2 fairly impressed me, the 11/2,8 is tighter still. Its focus ring turns on a hermetic helical over 90 degrees, that, considering the view angle, is enough to achieve accurate focus from infinity to 0,17 metres. In comparison to a classic Voigtlander, or Leica, the twisting action is positively sandy, but next to a number of twenty year old Zeiss lenses, not to mention loads of lenses from China and Russia, it is perfectly acceptable. At 15.4 ounces (436g), the lens isn't light, but it's also not exactly what I'd call heavy, either. The smallish size and metal construction mean that it feels a bit "dense" in the hand.

Physical Characteristics

With our usual approach we cannot get decent values on the vignetting of fish-eye lenses. What I can tell you is that the vignetting figures are significantly lower than those of rectilinear ultra wide angle lenses, especially compact ones. Sony A7rII | AstrHori 12mm 2.8 Fisheye | f/2.8 Whatever the limits of my abilities, the fun-factor of using a fisheye is unlimited. This bad boy covers 180º, with a bright 2,8 maximum aperture. Talk about fun. I’m sure loads of you out there know what it’s like to shoot fisheye lenses. Move a little and the entire frame changes. Sag a shoulder slightly and the horizon bolts down. Because it covers 180º and does the bulbous fisheye thing, you have to remember a few things: You don’t have to take my word for it either, everyone at the photowalk saw how much I was enjoying myself… and actually, many of them were apparently really quite enamoured with it too. Like anything in photography though, how useful this lens is in practice is going to come down to the individual photographer. But, the real point is, until recently, there was no 11mm f/2.8 fisheye lens in M-Mount… there is now! The TTArtisan 11mm f/2.8 Fisheye might be imperfect, bonkers and really quite niche, but as an M-Mount photographer, I’m a lot more pleased it exists than I expected to be! The AstrHori 12mm 2.8 is way bigger and heavier. It has better flare resistance and CA correction but performs similar in terms of sharpness and coma correction.
