Yes there is a big enough difference between 28mm and 24mm on film that you will notice. The next noticeable jump in FL would be the 18mm-20mm then 15mm. The K15/3.5 on film is really wide.

The K18/3.5 and K15/3.5 are pricey, but you can get the K20/4 at a decent price.

Not much reading material out there on the K24/3.5. A handful of reviews and that's about it.

Well there's always the photos - don't they count? PENTAX : Select a PENTAX interchangeable lens camera or a lens model


My quick take, after looking at the photos, is that the K24/3.5 probably doesn't match up to the IQ of the K28/3.5. The K24/2.8 looks better to me, and the A24/2.8 looks better than that.

I can personally vouch for the IQ of the K28/3.5 and A24/2.8, having owned both.


EDIT: I didn't know this ahead of time, but it looks like other forum members' ratings agree with my assessment above. You should probably believe them.

As a point of comparison (since you already have it) the K28/3.5 was sharper than the A24/2.8, but I liked the A24 more. The colors and rendering were nice, I liked the focal length more, and as much as I appreciated the sharp and colorful (yet cooler, I think) rendering of the K28/3.5, the f/2.8 aperture seemed better and the A setting is convenient.

24mm is much wider than 28mm.
28mm was the widest I had during film days and it was often not enough for many urban scapes.

24mm to me is much better (I use it on FF digital nowadays).
I'd put it this way, its wide enough for most things, be it a table of 10 people at a dinner to many landscapes.
All this while keeping perspective and lens distortion at reasonable levels.
If I wanted a small, f2.8 wide lens that would 'do almost everything', 24mm would be it (eg. K24/2.8)

20mm, imo is the best legacy wide FL w/o much issues.
Beyond that, and these old lenses are just not that good compared to more modern options.
Its the wide FL I would use if I wanted a reliably wide lens that I am pretty sure is wide enough for most things. (the 24mm can be not enough in some cases)
It does foreground>background shots better as its wide FOV gives a better 'sweep' from near foreground to bkground and some sky.
Perspectives start to get pushed at 20mm, but still ok to me.
Sort of like widest w/o going funky.

The reviews on the forum seem pretty decent for the K24/3.5. I was just surprised to not see much on Flickr or anywhere else. The price a lot of tees sell for suggests enough people like it and are willing to pay decent prices for it. I feel like I got a pretty good deal compared to average prices on the forum reviews and other places I've seen it for sale.

I think the prices reflect the supply of these lenses rather than the quality. Are Pentax 24's better than Pentax 28's? Probably not but there are millions of Pentax 28's out there keeping the price low on them. But the Pentax 24's are still fairly reasonably priced and a 24 does change the FOV a fair amount so it's reasonable to buy one.
