Pentax: DA lenses compatible with 35mm film cameras?

Does anyone knows if this works, without vignetting and other fuckery? Thank you

Cut & paste from wikipedia:
"The DA lenses were designed specifically for the Pentax digital cameras incorporating an APS-C digital sensor. As the APS-C sensor has a smaller surface area than 35mm film, these lenses are not generally considered to be compatible with older cameras. They also lack an aperture ring, limiting their use on cameras that do not support automatic aperture settings. Most of the DA zoom lenses are available in weather resistant (WR) versions to match the weather sealed capabilities of the medium to upper level Pentax DSLR camera bodies. While older models still have the in-body screw drive autofocus system, newer designs marked "DC", "SDM" or "PLM" feature silent, in-lens autofocus motors.

Some lenses of this product line such as the DA 10-17 Fisheye were co-developed with Tokina"

Google is your friend.

From what I’ve read some of the primes will cover full frame, I believe the 2.4/35 is one of them for example. Pentax Forums has a user reviews database and some people will report on full frame coverage, here’s a link to the DA lenses:

One thing I forgot to note since you specifically mention 35mm film cameras, you’ll need a fairly modern body in order to use the DA lenses, here’s a compatibility chart:

There are two parts to this, the DA lenses lack an aperture ring so they only really work on cameras that can control the aperture automatically - this means cameras that used the 'A' setting on old lenses (other cameras will remain stuck on minimum aperture). Even so, most of these will only work in program or shutter priority modes - these are the only modes where the camera controls the aperture. The only fully functional option is the Z-1(p) - in the US PZ-1(p) as these allow the use of 'hyper modes' which also allow manual & aperture priority with the lens aperture set on 'A'.

Vignetting may occur, many zooms may work with specific focal length & aperture combinations. The DA50/1.8 is reported as FF compatible, the DA10-17 fish-eye effectively works as an FF fish-eye at 17mm but vignettes at wider focal lengths (it's the only one I've tested).
