Lens FL is stated in reference to 35mm dimensions. Hence, FF is pretty much a 1-to-1 vs. 35mm film. With a 1D the field of view is constrained and you multiply by 1.3 to get the equivalent field of view. It's still a 17-55mm lens, with the same reach (multiplication) of a 17-55mm, but with the field of view narrowed (cropped). For Rebels and the 7D the factor is 1.6, but the reach is still unchanged, just the field of view is reduced.

If I take my FF 5D MkII and take a picture at 24mm and take the same scene at 24mm with my 7D, if I crop the 5D2 image (maintaining the aspect ratio) around 40% the subject will be the same size in both the uncropped 7D image and the 5D2 cropped image. All that's changing is the field of view, not reach or focal length.

P&S makers have further confused the issue by making up terms such as "digital zoom", which is merely in-camera cropping. With a tiny sensor the IQ quickly goes to hell in a hand basket.

I meant to say that the 17-55 on a 7D would give the same framing as a 27-88 on a 5D.
I didn't mean that the 17-55 would become a 27-88 lens if you put it on a 5D.

I just wanted to say thanks to the forum members who provided, opinions, input, and suggestions.

I received my camera today. The lens are shipping separately. In addition to the 50 1.4 I ordered a 17-40mm f/4 L as well. I will decide which of the two I like better and return the other. Who knows, I may keep both.

Oh yeah, I also picked up the Magic Lanterns user guide.

Thanks guys, I will post some pics as soon as my lenses arrive.

Everything I have read about L lens seems to be very positive.

Very cool. On my APS-C I like the 17-40mm f/4L more for a nice walking around lens, but on my FF I like/use the 50mm f/1.4 more.
