Review
The SIGMA Super-Wide II 24mm F2.8 is an autofocus (hereafter AF) wide-angle lens released by Sigma in the era of film cameras.
It is a very old lens and I bought it junk, but other than the sticky exterior, it works normally.
Sigma’s corporate culture is to delete all information on old lenses after a certain point, so there is very little official information on this lens as well.
However, there is some information on the web, and some overseas sites have detailed specifications.
The information is summarized as follows: the MF lens of 1986 was the base lens, and the AF lens was released in 1988.
After this lens, Sigma released 24mm focal length lenses for SLR cameras (24mm/F1.8 and Art 24mm/F1.4) and for mirrorless cameras (24mm/F1.4, 24mm/F3.5 and 24mm/F2).
The 24mm focal length is the most varied of the Sigma single focal length lenses, along with the 35mm focal length.

Since this lens is an old 1988 wide-angle design (simple lens construction with only a spherical lens), distortion is noticeable when used with APS-C sensor cameras, and the image lacks sharpness for use with digital cameras, one-sided blur is felt, and suspicious light appears when backlit, either due to design problems or lens deterioration. It is not clear whether it is a design problem or the lens is deteriorating.
When shooting with the white balance set to “auto” mode, the images are quite likely to show yellowish, nostalgic colors. Since this was taken with a digital camera, the colors can be changed in any way if the white balance is adjusted on a PC, but the fact that such colors are produced without adjustment is something that can be enjoyed as a taste of the lens.

As I actually used the lens, it is not a lens that I would dare to use in the digital age, but I am glad that I purchased it because it is rare to find a Sigma SA mount lens in a junk shop. The SD9 I bought at the same time had either a FOVEON sensor or peripheral circuit failure and could not record images properly, so I feel that the price was high for two pieces of junk.
