Really? I thought that if you've got an EF-S lens rated 10mm, the lens is still actually 10mm, it's just downsized to fit the sensor. (10mm is always 10mm, as one of our UHH gurus frequently states.) Ergo, on a 1:6 crop factor camera (as the 7D) it yields the equivalent of 16mm, not 10mm. So you still have to do your multiplication. Am I wrong? I want to be sure on this for my sake as well as the OP's. Thanks. I don't mean to be obnoxious!

Great to know...I'm really leaning towards that lens...the only L lens I have is the 17-40, but with the crop factor it isn't as wide as I thought it might be.

What to do? What to DO? Well, as Joe said, he can get quality 20x30" prints from a DX (APS) sensor. So I think the crop sensor/FF comes down to this:
As a format, FF favors the wide-angle end of the spectrum, and DX favors the telephoto end. After a certain amount of shooting, most people could probably decide if they seem to favor one end of the spectrum over the other. Do you find yourself shooting more with your 70-200mm or the 10-24mm?
This probably oversimplifies it a bit, but the general idea is valid.
Good question!

I chose not to because I did not want to strand the investment.
Some thoughts:
If you want to do wide shooting, that is the best way to go on a crop body (there really are not other good options although the 14 (canon or other) will likely satisfy.
Buying an efs when there is an ef alternative is likely not worth the 'savings' if you think you will go ff
You may want to keep the crop body even if you have a ff for reach (indeed, you may not find ff all that desirable

I shoot a 7D and had upgraded from an XTi. All my lenses are EF glass with the exception of the fantastic EF-S 10-22 mm which would be wearing the red stripe if it were an EF lens (in fact, it is made in the EF factory). Why EF lenses? The best optics available (super low dispersion glass, fluorite elements, etc.), a more rugged build, better coatings, better weather sealing, better resale value, and you're always getting the "sweet spot" center of the lens focusing your picture. Other than that I cannot think of a good reason. :lol:

I have both the 7D and the 10-22. I love both of these and think you would be happy with them. Attached are some pics that I took with them.

Those are beautiful. I'm beginning to think I do need that lense. Thank you.

i have crop sensor and full frame....and i sure didn't buy full frame just to get large size prints.
put a 50mm on a crop sensor and a 50mm on a full frame and tell me the only difference is the ability to get large prints!!!!????
if you have a crop sensor camera.....do yourself a favor and do not look through a full frame. that way you will be always satisfied with your crop sensor.
as far as print size....even when I just had the one 7d, I made billboard size prints for our banner printer here at work and they were great.
i guess I never thought that large prints was the biggest reason to move to full frame...
like i said, crop sensor owners...stay away from full frame and you'll always be happy with your crop sensor cameras.
don't get me wrong..i have 2 of the 7d canon bodies and i love them....but full frame is a whole 'nuther world. I have 2 nikon full frame bodies. if i would have only never looked through the lens at full frame.....i probably would have never bought them.
you cannot miss what you don't have or have never seen.

Good points! Decisions, decisions! I'll have to wait until Black Friday to upgrade anyway!

Since you will probably keep the 7D as a backup body, an EF-S lens could be a good investment. One EF-S lens that may be worthwhile is the Canon EF-S 10-22mm f/3.5-4.5 USM. The lens is very good and would get you a decent wide angle lens for the 7D.
Also, consider how much you would use the lens. I wore out an EF-S 15-85mm lens from use.

I have a 50D which uses the EF-S lenses and the 5D, which I bought sometime later, that uses only EF lenses and knowing what I know now I would stick to only the EF lenses for both cameras.
I have the EF-S 10-22mm which is in my opinion a very nice lens and a great value and also I bought the EF-S 17-55mm rather than the "kit" lens, but now when I go on trips it means taking along extra lenses that I may not use or leaving one at home.
I have the EF 24-105 mm F4.0L and 100-400mm 3.5-.5.6L
which can be used interchangeably on both cameras and so the 10-22mm stays on the 50D most of the time and is used for wide angle shooting and the others get used mostly on the 5D.
It's not as versatile and economical a setup as having all EF lenses would be and had I known that I would be getting the 5D in the future, I would have obtained a range of lenses that would be useful on both cameras without duplication.

I not sure where many of the contributers here get the impression that EF-s lens no not need the crop factor applied. ALL lens are in mm and if its a crop sensor camera you need to apply the factor mo mater if it is an EF or and EF-s lens.

Listen to Jim... I don't have a 7d but I do have a crop sensor body and a 5D2. Crop sensor owners who have never handled a FF do not know what they do not know. It costs more, but beyond the 10-22, EF lens will probably be most economical in the long haul. Can be used on both. I look for crop sensors to disappear except perhaps in an entry level camera that comes with a kit with ef-s lens and for the inability to use ef-s on FF bodies to continue. It makes no sense to keep crop sensors in high-end cameras since the cost of sensors are coming down. I think the 6d is a move in that direction, coming after the 5D3. Of course, I predicted that the SST and the 747 wouldn't fly and that the QE2 wouldn't float. :roll: 'Canon wouldn't do that," you say? They've never been bashful about leaving millions of loyal customers stranded before, as with the FD lens mount.

i have 10-22 efs and 7d its the least expensive lens i own.and are very easy to sell.as for ff why.
