15 X 1.6 = 24 ? Old school wide angle.

A couple of review sites with the latter being dependable:

if you're not thinking about compatibility with full frame bodies in the future:

Canon 10-22mm

can someone explain the 1.6? I'm confused

[CaptainTom]

for decades the SLR was a film camera that produced a negative (or positive/slide) that was 35mm wide.
Today's digital SLR's have a sensor instead of film. The sensors are not the same size as 35mm SLR sensors (with a couple of exceptions like the 5D, and are referred to as "full frame").

Since the digital sensors are smaller than 35mm, the image that is captured, when printed at a comparable size appears to have been taken from a closer perspective, or from a "longer" lens.
In the case of the Canon 20D this equates to an "crop factor" of 1.6.

In short, a photo taken with a 20D digital SLR and a 50mm lens and printed full frame, will be the same as a 35mm camera and an 80mm lens taken from the same spot. 50 X 1.6 = 80

To us old timers, a wide angle on a 35mm camera was something 35mm or shorter.
In digital terms that would be 20mm or shorter. 20 X 1.6 = 32

i understand. I was looking at sample pics for the lens you suggested and they seemed too wide, but then again, maybe they weren't taken with the 20D. Maybe they were "full frame"

Tamron 17-50

Sigma 18-50

Fast lenses at a good price with very good reviews.

Just saw this one. $200 right here on the forum

[adrianisonfire]

i have a tamron 17-35mm for sale

here's a comparison to the canon 17-40L

[Steelsun]

If you want a cheap but acceptable lens, there's always the Canon EFS 18-55 lens that came with the 20D when bought as a kit.

I have one laying around here somewhere that I'll sell for $50.

I've replaced it with the SIgma 18-50 mentioned above - better quality glass. I am also looking to get the Canon 10-22 soon, as every time I borrow one, it seems to be the main lens on my camera.

I also have the Sigma 18-50 f/2.8 and I've been happy with it.
