What do you think is better for a Canon 60D body:



- Canon 15-85 USM

- Canon 24-105L

Get whichever one is better for your photography needs. They are different enough in scope.

15-85, without a doubt.



The 24-105 is the standard zoom for full-frame gear. It'll work on a 60D but it'll be much less useful that the 15-85, which has been designed with cameras like 60D in mind.

Just one lens? Most would prefer the 15-85. However, if you plan to start building a system, the 24-105 could be a better start if you later add an UWA. Also consider the 17-55/2.8 IS. Less range but much faster.

The only reason to consider the 24-105mm f4 on a crop body is when you have real use for its weather sealing. Or that you know you will switch to full frame in a few years. 24mm is not really wide, and 105mm is not all that different from 85mm.

Personally I would prefer the f2.8 from the Sigma 17-50mm f2.8 OS HSM... and get a 2nd lens with it (longer). A tele zoom or a portrait lens like the Canon 85mm f1.8 USM, depending on what you think your subjects will be.

I respectfully disagree. FL preferences are extremely personal. When I traded my 24-105 for the 17-55 it was for the extra stop, not for the FL. I actually like the 24-105 FL on crop better than 17-55. Luckily, this can be easily solved by adding the 135/2 (previous) or 100/2.8 IS (current).

As a general-purpose zoom lens? Then definitely the 15-85 on a crop-sensor camera.

The 24-105 is a very nice lens, but the difference between 15 and 24mm on the wide end is huge.



And besides, the 15-85 is basically Canon's equivalent to the 24-105 for APS-C (the same way the 17-55 is meant as an APS-C equivalent to the 24-70).



[size="1"](Yes, they're not exactly equivalent to their FF counterparts from a technical point of view, but they serve the same purpose on each camera system)[/size]





Of course, you can use the lenses any way you want. There's nothing wrong about using a 24-105 on a crop-sensor camera, but the resulting 38-168mm range is probably not for everyone.



After all, there is a reason someone thought that it would be a good idea to start standard-zooms at 24mm (or 15mm in case of APS-C). It's just very convinient.

And apart from the range ... optically .. what do you think is better?.

From my personal experience with the 15-85 on a 7D: Resolution is very good across the range, even wide open.

Distortion and vignetting are not that great at the wide end.

Build quality is decent but not L-like. Also, it does have zoom creep (develops over time).



The 24-105 is a very fine lens (I'd definitely get one if I had a FF camera), but having a standard zoom that starts at 15mm (24mm equiv.) on an APS-C camera outweights the benefits of the 24-105 for me.

Reminder: FL is the most important aspect of a lens.
