I dont know much about the lens range with canon. Im wondering if the Ef range is for the Drebel only and will they fit other canon cameras in the future eg 20D and any new replacement for the rebel. I would like to know this in case I decide to upgrade in a few years from the rebel. I dont want to spend the money on these lenses if I cant keep them.

EF is the designation of all autofocus lenses Canon has issued since 1988 when Canon did away with their manual FD line. EF lenses work with ALL autofocus Canon film and digital cameras- ALL of them, including the Digital Rebel and 10D, 20D, 1Ds, 1D mark II, etc, etc. If you buy an EF lens it will work with any Canon AF body you own, digital or film, now or later.

For now the EF-s lenses will only work with the Digital Rebel and 20D.

If you stay with future 1.6 sensored bodies you should always be able to buy either EF or EF-s lenses as it seems Canon has decided all future 1.6 bodies will be EF-s mount. Note however the EF-s lenses do NOT work with the 10D or earlier D30 or D60 bodies. If you ever upgrade later to a larger sensor body, EF-s lenses will be worthless as they will not cover the image area of the bigger sensors.

you must mean EF-S which at present only fits DRebel and 20D. They are designed for the smaller sensor and shutter. The promise is that because they are smaller you can get more quality dollar for dollar.

I don't know that I buy the dollar for dollar thing. The 18-75 lens is virtually the same lens as the current 28-135 EF lens. The two almost look alike, but the 28-135 EF costs about $200 less than what the 17-85 EF-s is going to retail for. Smaller size, larger expense. That's the trade-off. The optical quality difference will be very close. Heck, the 17-85 almost costs as much as a 17-40 f4L and is going to be MORE expensive than a 70-200 f4L. Anyone buying these new EF-s lenses will be paying a hefty premium.

Actually, I don't think the 18-75 lens is virtually the same lens as the current 28-135 EF lens froma manufacturing standpoint.

Perhaps a EF-S 28-135IS would be cheaper than the current EF 28-135ISlens, it could certainly have smaller glass.


BTW, I'm not necessarily convinced of the cost benefit myself but I have noticed that prices are sometimes quite a bit higher at the wide end - like 18mm as opposed to 28mm

IMO there's an argument for both sides:
o The EF-s 17-85 is a lot less expensive than a 28-135 and a 17-40 plus more convenient to carry around too
o The Oly/Kodak - Nikon camps have long tout the benefit of theses 'digital' lenses for the smaller size sensors since the projected image strike the sensor at a less acute angle with all their benefits (ie less reflection / more contrast + being smaller/lighter).
o People shooting wildlife may actually benefit from the 1.6x factor - Think @ how much more one would have to pay at the long end for the same focal lenght on a full frame camera :?
o Landscape folks may want to go with full-frame, but I think in the long run most folks will favor APS-c size camera, especially now that the 580EX flash is designed to compensate for the crop factor as well... Check the Oly f/2.8 long lenses -> wait till they apply this EF-s concept to long lenses... it'll be a lot cheaper (and lighter) :G:G:G

I do love taking my 70-200 f4L to baseball and football games with my 10D or Digital Rebel and being able to get in closer to the action with those bodies than I could with my EOS 3. It's cheaper and lighter having a 1.6 body like a Digital Rebel with that zoom than buying a Canon 300mm f4 lens for a film body.

Agree,lens reachcan definitely be cheaper for the 1.6x bodies, but what has film body to do with it anymore? The pro 1Ds/1Dsm2 bodies are full frame, butif you can fork out the $(both are listing at 9999$cdn)for a 1Ds you probably don't mind the expense of a300mm/400mm-F2.8Lor 500/600mm-F4L either. (Or the 1200mm-F5.6L if someone would care to send me one to test :G )

Now there is a thought a 1200mm + a 2xTC + a 1.6 body for a 3840mm effective lense, paparazzi here I come :lol::lol::lol:

Food for thought:

o EOS 1Ds mrkII:
Weight - 1.565kg (55.2oz)
Size - 156x158x80mm (6.1x6.2x3.2in)

o EOS 20D:
Weight - 770g (27.2 oz)
Size - 144x106x72mm (5.7x4.2x 2.8in)

twice the weight before adding the larger (and heavier) lens... but it has twice the resolution! :-):-):-)
-> It looks like the APS-c sized cameras are here to stay...
