The very little known the Risespray 11mm f/2.8 (11 F2.8) Fisheye lens.
It is a fisheye lens made in China. It is available for full-frame mirrorless cameras with Sony FE/Canon RF/Nikon Z mounts.
I have the Sony FE version, it's a manual focus non-electronic lens. I bought it as the cheapest fisheye for the [full-frame] Sony FE mount, it cost me about $140. The TTArtisan 11/2.8, the 7Artisans 10/2.8, the Samyang/Rokinon 12/2.8 are more expensive.
This lens has a clickless aperture change from f/2.8 to f/16:
I don't like this kind of control, it's very uncomfortable for photography. The aperture ring is a bit stiff, but it's easy to accidentally move the setting off, and it's almost impossible to blindly set the desired aperture value.
The best option for non-electronic lenses is an aperture preset mechanism like on older lenses. Unfortunately, I have not seen this on modern lenses.
The aperture consists of 10 blades:
Optical design: 11 elements in 7 groups
An unusual push-on metal cap:
I think the cap does a pretty good job of protecting the convex front optical element. If the cap doesn't come off by itself, of course.
The lens isn't that small. A little bigger than the Зенитар (Zenitar) 16/2.8 Fisheye with the Pentax K-Sony FE/E adapter.
What is the origin of the lens, since Risespray is not a manufacturer? This lens is very similar to the TTArtisan 11mm f/2.8 Fisheye:
(TTArtisan 11/2.8 Fisheye, mirrorless versions)
The optical design is also very similar (to the mirrorless version of the TTArtisan):
(TTArtisan 11/2.8 Fisheye)
Both lenses (the Risespray and the mirrorless TTArtisan) have the same distance scale (m): 0.17-0.2-0.25-0.3-0.5-1-∞.
The mirrorless TTArtisan has 7 aperture blades, but the later SLR version has 10 blades.
(TTArtisan 11/2.8 Fisheye)
Unfortunately, the Risespray lens has a clickless aperture ring like the mirrorless TTArtisan, while the SLR TTArtisan has a click ring.
I think the Risespray 11/2.8 Fisheye is a clone of the TTArtisan 11/2.8 Fisheye lens (I don't know the original manufacturer), but it is cheaper since the lens has just started being sold under the Risespray brand.
My copy of the Risespray 11/2.8 Fisheye was new in a sealed box. When I started using it, I was confused by how far beyond infinity it focused. Then I noticed a strange slipping of the focus ring. I even tightened the screws of this ring (hex 0.9mm). But that didn't help.
It turns out that there is massive play in the focus mechanism:
This is quite unpleasant, there seems to be no quality control at all here. By the way, the seller's reviews also contain complaints about the quality of the lens.
My hope is that I can get the lens repaired and have a chance to use it.
