Description:
This is the early version superwide, introduced in 1981 according to sigmauser.co.uk. Structurally different to the superwide II. Specifications are the same though, and they are at least optically similar if not identical. Typically P-KM mount, (also M42).
Some of these suffer a technical mount problem, as described in this thread. The aperture lever guard for some reason is misaligned with the aperture lever, see pic, the result is that the lens won't mount on some Pentax DSLR's because the guard bumps against the powerzoom/SDM autofocus contacts. The necessary solution is to remove, or at least prune down, the errant guard. This is easy to do - it's only plastic.

Multi-Coated 24mm wide angle.
CFD ~ 15cm/6"
1:4 Macro,
f2.8 - f22, half stop clicks.
6 blade iris
52mm filter ring
Focus throw ~ 180 deg
Weight 195g
Mount Type: Pentax K

Pros: bokeh at short distance, short min focus distance, price
Cons: sharpness also in the centre
Sharpness: 7    Aberrations: 8    Bokeh: 9    Handling: 8    Value: 9    Camera Used: Fujifilm XT-20    New Or Used: Used   

I took a few shots at shot/mid-distance with it and the Canon FD 24mm here: https://www.rustichelli.net/Hobbies/Photography/LensTests/24mm-a-tale-of-two...-and-Sigma.php

The Canon is maybe a bit better apart from the point of view of bokeh, definitely better for centre sharpness, but the performance of the Sigma is not shabby and it can produce very usable images, with good contrast and vibrant colours.

This lens is capable of decent shots and the price is so low that you can buy it without hesitation, but I have tested some other cheap 24mm and I think there are better options, possibly incl. the Vivitar 24mm make by Cosina.

Pros: pretty decent
Cons: not as good as superwide II
Sharpness: 8    Aberrations: 8    Bokeh: 7    Handling: 8    Value: 10    Camera Used: K-r    New Or Used: Used   

Since I had both the early superwide and the the superwide II for a wee while I was able to do some comparison shots.
While the lenses have clear similarities they also have clear distinctions in optical performance. Most immediately noticeable: the superwides warmer tone. Resolution was fairly similar at matching f, I would say, although that assessment was blurred by the very distinctly better contrast of the superwide II. Add in the more natural and brighter colours and that's overall a clear preference. But the superwide is pretty decent and can be picked up much cheaper.

Sample pics + crop, pentax K-r, from RAW, same default pp LR3, f8.

Superwide.



Superwide II
