In joining the digital age of photography over the past year with the A95 and now the S2 IS Ihave beenattempting to dispose of my EOS Rebel 2000 (Date Back) fitted with Canon's EF 28 - 105 mm f/3.5 - 4.5 USM lens to no avail, at least not at a price I felt was fair.

Aquestion crossed my mind, if I upgrade to the dSLR Rebel XT, could I use the 28 - 105 lens from the Rebel 2000? as well would it be a lense worthy of digital photography?

While I haven't used it for some time, it is packed in its original box etc. in immaculate conditionand from what I can remember was a great lens at the time for me.

Yes you could!

... you just need to factor in the 'crop factor' (1.6x) that's all

NHL;

Your reply came in 9 minutes.

Nice to see someone else is up early; it's 7:10 am where I am, are you an early riser as well with nothing else to do until the sun rises?

and 'crop factor' (1.6x) means what?

Your 28-105 has an effective field of view of a 45-170 lens
i.e. you lost your wide angle, but gain some tele instead on a Rebel XT...

Wildlife are most active during theses early hours; However it looks like the weather is souring with overcast!

NHL; further to our previous conversations re: "1.6x crop factor". How does anyoneknow this? I see a lot of members discussing it. Thanks!

FYI - http://www.steves-digicams.com/2005_...lxt_views.html

Image size [align=left] 22.2 x 14.8mm [/align]
The image size for your EOS Rebel 2000 (date Back) is 36 x 24mm for a 35mm film camera

i.e. 36/22.2 = 24/14.8 = ~1.6 (or take the ratio of their diagonals)

I have a Canon Elan 7 with a tamron 28-200 lens....could this also be used on a Rebel DSLR? is there a link somewhere where one can check out and make sure. I'd hate to ruin a new camera!!!

Dragon...

The Canon 20D and both Digital Rebels will use any Canon EF or EF-S lenses or compatibles (Sigmas, Tamrons, et al). All lenses will have the 1.6X crop factor described above when used with these cameras (due to APS-C sensor).

All other Canon DSLRs will use any Canon EF lens, but not EF-S lenses.

Thank you for the reply. How do I make sure that my current lens would be compatible? it is a Tamron, 28-200Zoom Wide Angle-Telephoto AF f/3.8-5.6 Aspherical XR IF Macro Autofocus Lensthat I currently have on my Elan 7

I am really considering the Rebel XT..and if for a while I could use my current lens and save up for one that is a bit better, that would be marvelous!

dragon..

every lens that works on your elan 7 will function perfectly fine on your Rebel XT.. but your tamron will become a 45-420 lens due to the aforementioned crop factor..
