Review
1．Overview
The TTArtisan 11mm f/2.8 Fisheye is a fisheye lens for the Leica M mount. In addition to the M mount, it is also sold for mirrorless cameras.
The lens consists of 11 elements in 7 groups, with a minimum focusing distance of 0.17m, and it does not work with the rangefinder of a rangefinder camera.
Filters cannot be attached to the front of the lens.
The M mount version comes with a dedicated viewfinder, so it is more expensive than other mounts.
2．Usage
As it is a fisheye lens, the image is naturally distorted in the corners, but the image does not break down even in the corners, and the image is flawless across the entire surface.
The contrast is slightly low, and ghosting occurs in backlit conditions, but this is unavoidable since it is an ultra-wide-angle lens.
The lens is easy to operate, with a focus ring that is wide enough to allow smooth focusing. It is unusual to have a pin attached to the aperture ring, but since it is not changed frequently, it is not appreciated.
The included viewfinder is only for checking the shooting range, but it does not look very good, so it is more reliable to shoot with an EVF attached. Therefore, if you do not care about the versatility of the M mount, it is cheaper to purchase a dedicated mount without a viewfinder.
3．Add info.
The specifications of this lens are listed as compatible with 35mm film size, focal length 11mm, and diagonal angle of view (hereafter referred to as angle of view) 180 degrees. I was intrigued by the idea of creating a fisheye lens with a focal length of 11mm, so I tried it out, but when I looked at the actual photos, I didn’t feel any clear difference from a 16mm fisheye lens.
This is because I was distracted by the difference in focal length between 11mm and 16mm and neglected the fisheye element.
In 35mm format, a focal length of 16mm has an angle of view of 107 degrees, which has been expanded to 180 degrees to create a fisheye. On the other hand, this lens has a focal length of 11mm and an angle of view of 126 degrees in 35mm format, expanding the angle of view to 180 degrees.
There is a difference of 5mm in focal length and 19 degrees in angle of view, but as fisheye lenses, both expand the range to 180 degrees, so the shooting range is the same.
The curvature of distortion will be different between 16mm and 11mm, but the difference will likely only be noticeable if you use a tripod and shoot the same subject.
If there’s one advantage to the 11mm focal length, it’s that the depth of field is deeper than with 16mm, making it more suitable for deep focus shooting.
