DA Lenses on a Full-Frame 35mm Camera

I came across an out-of-date roll of Kodak MAX 800 film this morning and instead of throwing it out, decided to see how my three DA lenses would perform on my 35mm film camera, (an old ZX-5). I didn't test for anything except how well the lenses would cover the full-frame format. I didn't want to spend too much time so I just went into my back yard and blasted away. I then took the film to Walmart where they developed it in an hour. I scanned the negatives on my Canoscan 8600F Scanner and posted the results on Flickr (see the link below). I didn't make any corrections since all I was interested in was coverage. The subject could have been better because of the shadows, but, I think you can get an idea as to how well the lenses cover. I didn't shoot at every focal length (except for the fisheye), but mainly just the wider settings, until I was pretty sure there was no more vignetting. Besides the fisheye, the other two lenses were the 18-55 and 50-200 kit lenses.

Thanks for sharing

and I guess we need a good database of modern glass usability on FF film/sensor- this reminds me of my own 10-17, 16-45 etc. experiments on *ist :-) Biggest disappointment during last days was DA35 Macro- very obvious vignetting even in viewfinder- so no go here :-(
Best and happy shooting and will give a try with my "digital" glass, JR

really dumb question department

did you shoot these shots with or without lens hoods and filters? Remember the FOV of a DA lens on an ASP-C sensor is less than on film and the hoods are probably specifically designed for the ASP-C sensor

other comments
- Looks like the 10-17 has a back shield that limits FOV unnaturally
- 18-55 might get by OK without filters
- 50-250 looks fine

Best way to really do this is against a uniformly lit block wall.

ps, my 10-20 sigma vignettes at 13 mm on a film camera

No lens hoods, except for the built-in one on the fisheye. (I really need to do these over with a better subject so you can see the vignetting better.)

I have try the 16-45mm on my K2, it can cover FF at about 21~22mm and above.

So the DA series are the only lenses that won't work with Full Frame Cameras?

Correct, but the jury is still out on _some_ of the DA primes. For example, the DA40, 70 and 200 (and probably 300) all cover the FF, but whether or not the edges were actually designed to hold sharpness that far is still in question. Note the DA40 thread here - https://www.pentaxforums.com/forums/pentax-slr-lens-discussion/26021-da-40mm-...via-100-a.html

Of the three lenses tested in this thread i.e. 10-17, 18-55, and 50-200, the 50-200 covered at all focal lengths; the 18-55 covered fully from 35mm on (but at 24mm it was usable with a little cropping); and the 10-17 covered fully from about 15mm on, (but was usable at 13mm with a little cropping).

Again, I don't know about the quality of the image at the edges, but at least the coverage was there.
