I reviewed this 'a' mount lens almost ten years ago when there were no newer Sony equivalents available. However, Sony eventually come up with a Carl Zeiss 24mm /2 wide angle lens; it was very expensive at the time, ($1400) and a pretty good lens; unfortunately, I was not able to give it two thumbs up, see the review here.
Now that I've re-visited the Minolta AF 24mm F/2.8, I can see that it is actually very sharp stopped down to F/5.6-8 using an APS-C camera, and F/8-11 with full frame. It does suffer from a soft periphery at F/2.8-4, and soft extreme corners at F/5.6. Fortunately, If you can live at F/5.6 to F/11, this lens is a very good value. Current eBay prices are around $150 for a good copy.
The Minolta AF 24mm is still a good solid choice for interior work, or landscapes at F/8-11 using a full frame camera. For those using APS-C, the focal length would be about 36mm (in 135 film format).
Unfortunately, as we creep into 2018, Sony still has not produced a 24mm focal length 'FE' lens.
If you have an APS-C camera and want excellent optical qualities in this focal length, get the superb Sony CZ 24/1.8. If you're on a budget, check out the Sony pancake 16mm lens, which has the same coverage as a full frame 24mm lens.
