Compatibility on Canon EOS IX Camera

<p>Will a lens designed to work on small sensor digital cameras also work on the old APS Film bodies? I have a Tamron SP AF 17-50mm f/2.8 XR Di II LD IF Lens for Canon mount and would like to know if it is compatable with the Canon EOS IX APS Film body? I believe it could be a great combination of size and usefullness if they work hand in hand with one another.</p>

<p>In a couple of words, not really.<br /> Canon-made 'digital only' lenses (aka, EF-S) are specially engineered not to even mount on the 'full-frame' cameras, film or digital.<br /> Other brands will usually mount, but they are made only to cover the smaller sensor and so will vignette heavily on 35mm film cameras. You can shoot with them, but the edges and corners will not be covered.</p>

<p>However, all EF lenses and lenses made for 35mm film will mount on all Canon EOS cameras, large, small, or film. It's harder to tell on the non-Canon ones, but you can try it and if the corners are all dark, then you know it won't work well.</p><div></div>

<p>Yes I see the dark corners, but did you see them when you were viewing TTL. I have mounted this lens on the Canon EOS IX and while viewing TTL I do not see dark corners whatsoever. Are you saying it will appear on the film image what I do not see in the viewfinder?</p>

<p>No, most SLR cameras (with notable exceptions like the original Nikon F) show less than 100% of the captured image in the viewfinder. One old excuse was cropping by the slide mount. In the case above, I saw much less vignetting in the viewfinder on a 5D which was used here.<br>

That made sense for technical reasons in the film days, but I am not quite sure we don't get 100% finders on digital. Perhaps the limitations on lens+that darned mechanical mirror gadget.<br>

To see on film, you have to process it first, you can't trust the viewfinder on most models.</p>

<p>I would think using an APS sensor camera and APS film camera would have the same image size, so the lenses designed for APS digital bodies should work on APS film bodies. </p>

<p>Not 35mm.</p>

<p>You should get decent APS-C format film coverage with most APS-C digital lenses. Canon EF-S lenses won't mount but 3rd party lenses (Sigma, Tamron, Tokina) should.</p>

<p>The actual APS film format is 30.2 × 16.7 mm, but the C (Classic) option crops that down to 25.1 × 16.7. Lenses for APS-C digital have to cover around 24 x 16mm, so that's close enough.<br /> <br /> You might see dark corners if you select APS-H prints which use the full area of the negative.</p>

<p>I have used a Sigma 18-200 OS lens with an EOS IX. It was fine with the APS-C setting but vignetted a bit at the wider apertures and wider focal lengths with APS-H and APS-P.<br>

I always liked the EOS IX design. It would have made a nice "mini" DSLR.<br>

<p>Is it still possible to get APS film developed?</p>

<p>They still sell APS film and develop it in the CVS across the street from me. The lab looks kinda slow but a surprising amount of older folks still shoot a single roll of film which includes Christmas, grandkids graduation and their summer trip to Vegas...</p>

<p>I agree, the EOS IX/IXE would make an amazing wee DSLR. I'm not sure how Canon made them so small with a 1.25X factor. The IX is surprisingly close to EOS M size and yet has a pentamirror, focusing screen and reflex mirror.</p>

<p>This all started when I began downsizing my camera collection so I pulled out everything I own and found some cameras and lenses I had almost forgotten about. When I saw the Canon EOS IX I remember the attention it drew from others and the great photos it took. With a lens mount capable of using almost all Canon lenses it was hard to resist. I recently popped on a Sigma 50mm f1.4 and once again was amazed at the clarity and the vivid colors. But I am sticking with my decision to move away from Canon equipment over to Nikon. Just my personal choice for the moment, so the XTi, both Eos 5 (film bodies), Tokina 100mm f2.8, Tokina 35mm f2.8, Canon 28-135mm IS, 50mm f1.8 MK-I (Metal Base), Canon 28mm f1.8, Canon 85mm f1.8, Tamron 28-75mm f2.8, the Sigma 50mm f1.4, Vivitar 28-210mm f4.2-6.3 Series 1, and the Tamron 28-200mm lens all must go. I believe I will keep the EOS IX and the Canon AF35ML w/the 40mm f1.9 lens as memories to the past. Will be having a big sale really soon. Thanks for all the comments, I am constantly learning from my own experiences and what I read here provokes a continuous thought process. </p>
