I was wondering if somebody could clarify a question for me.
I've heard and read in a couple of places that digital cameras have a multiplier of 1.6 when speaking of lens length. For example, if you have a 500mm lens, once the multiplier is added, you are effectively running a 800mm lens.
Is this accurate? |

Digital SLRs have either 1.5 or 1.6. Depends on the camera. But yes, that's accurate.

Well, it depends on the camera.
1.6x crop factor holds for the 10d
But other's have different factors. |

Technically no... the lens doesn't change at all. It's more like taking a picture into PhotoShop and enlarging/cropping it to a 1.6x factor. So you lose all of the surrounding pixels because the image sensor is smaller than a 35mm frame (by a factor of 1.6).
Ideally, I'd much rather have a full size sensor. Let *me* decide if I want to crop/throw away the pixels. Of course, such cameras exist ... and you can buy one if you have lots of $$$.

most canon's are 1.6x, some are 1.3 (the 1d think?) and the 1Ds is "full-frame" (eg: no crop)
all the nikon bodies are 1.5x crop
the Kodak DCS Pro is "full frame"
and the Fuji S2 i THINK is FF as well, but don't quote me on that
