Your Questions About Canon Digital Slr Lenses

rob answers:

I own several Nikons and several Canon digital cameras.

Nikon: D-90, D-200, D-700 + numerous lenses and flashes.

Canon: EOS 5D Mark II, EOS 40D, EOS Rebel XSi, numerous lenses and flashes.

Both systems work fantastic for me. I’m not ready to get rid of either one.

Here are a few of the differences:
- One is an L lens, one is not
- L version has IS (image stabilization)
- L version has slightly better build quality

If you’re deciding which one you should get, buy the non-L version. Why? It’s half the price but is just as sharp as the L version. In my opinion the L version isn’t much of an improvement in terms of image quality. And although it features hybrid image stabilization, you probably won’t need it much unless you’re going to shoot portraits. But of course, purchasing a sturdy tripod can compensate for IS.

I would suggest going with the best camera and lens you can afford at this time. That means you can get out there and start getting some valuable experience as a photographer now rather than waiting.

That’s what I did and I have never regretted it.

rob answers:

You can only use autofocus lenses (e.g. Canon EF), TS-E and MP-E lenses on Canon DSLRs. The exception is of early EF-compatible Sigma autofocus lenses, only Sigma lenses with DG and DC are compatible on EOS DSLR cameras, this is to do with the lower operating voltage of modern EOS cameras. Some of these early Sigma lenses may subsequently have been “rechipped” by Sigma, so these lenses should be addressed on a case-by-case situation.

Non-autofocus lenses such as the R, FL, FD and new-FD mounts are not compatible. It is possible to make adaptations and conversions of FD lenses, but it’s not an ideal route to go down.

Furthermore, if you use any lens on a EOS D30, D60, 7D, 10D-60D, 300D-550D, and 1000D you will get a more telephoto field of view. E.g. A 28mm wide angle lens becomes a “normal” lens. And a 50mm “normal” lens will become a telephoto lens. Effectively the field of view you get is 1.6x longer than when that lens is used on a full frame digital/35mm camera. For example a 35-105mm lens on these cameras becomes less useful as it provides quite an awkward set of focal lengths, likewise your ultrawide 17-40mm type lenses become a standard zoom on these cameras.

On a Canon 1D mkI-IV you get a 1.3x crop, these cameras are designed for nature and sports photographers, who don’t care so much about wide and standard lenses, and prefer to have a little extra on their super telephoto lenses.

Only on the “full frame” 5D mkI and II, 1Ds mkI-III will you see the same frame as you would on a 35mm film camera.

rob answers:

Yes, but only EF lenses, no EF-S lenses whatsoever, they aren’t designed for you camera

film/f.f Digital: EF

digital: EF-S/EF

Don’t take Nike’s advice, he never has anything other than a word or two, and a link to say. That lens is not compatible with your camera.
