what's exactly the 1.6 multiplying factor and how it affects

I've been reading about the Canon Digital Rebel, but I didn't make clear this:

what about the 1.6 multiplying factor of the digital rebel?

If I put my Canon 24-80mm (conventional 35mm) lens in the dRebel?...
Can i take 24mm pictures?... (always talking in measures in 35mm)...

Thanks in advance!!..

You will probably want to do a search on this topic (see the top of the page). It has been discussed many times before.

If you put your 24-80 lens on the rebel then the lens will behave like a 38-128 lens.

If you want to shoot 24 mm you will need to buy a 15mm lens

There is a lot of information and explanations on the crop factor (That is a better term that multiplication factor IMHO) in this forum, you could probably find it by searching if you want it.

Bob actually has a great Politically correct term..

"Lens Factor" 8)

Lens factor

Geez, are we back into that again?

One group wants to argue that it is a magnification factor. Another group wants to argue that it is a crop factor. Another group wants to argue something else.

Rather than open up those religious wars again, I just call it the 1.6 factor and move on. Let each group assign whatever meaning it wants to that.

My mistake.. "1.6 factor"


We could call it the "X-Factor" for the more generic

If you aren't also using a 35mm camera, there is no reason for you to care. The "normal" lens for the DRebel is 28mm. A 24mm is a slight wide angle. A 14mm lens is significant wide angle for it. An 80mm is nearly three times the length of normal.

Look! Guys! It's quite simple. No religion involved. If you are considering full frame 35mm from a 300D perspective, 35mm represents a 1.6x multiplier effect. If you're considering a 300D from the 35mm perspective, the 300D's got a 1.6 crop factor .
