p.1 #1 · p.1 #1 · Canon 15-85 or 24-105 on a 50D?


I have a Canon 50D and am trying to decide between a used 15-85 for $500 or a used 24-105L for $600. I've read all kinds of reviews, but wanna ask it here. Is it worth the extra $100 for the L lens if I'm not planning on upgrading to FF anytime soon?

The 'L' on the lens is not your most pressing issue with these lenses, both are quite sharp, have good color and contrast. The issues are FOV 'field of view' and a constant aperture vs a variable one.

The EF-S 15-85 lens would give you a 24-136mm FOV FF equivalent on your 50D and has a variable aperture of f3.5 to f5.6, as you zoom out from 15-85mm.

The EF 24-105 on your 50D is like having a 38-168mm FOV, but the aperture stays constant at f4 as you zoom out.

You have to decide how wide a FOV you really want/need and what ISOs you are comfortable with; there are DOF issues as well but both lenses aren't that fast anyway. Your 50D, just like any xxD or Rebel body, has a crop factor of 1.6x and it is pretty critical to calculate FOV when considering what lens to buy.

Both are great lenses, you can't go wrong with either.

depends on your current lens but the 15-85 will probably be more useful on a crop

4 years ago I made the decission to buy the 50d + the 24-105 and I am happy with this combo.
In former (film-) days I used to shoot with my F1 and 3 primes most times: 35mm, 50mm and 135mm. And the 24-105 brought me at about the same perspectives in one optic.

We just had a long thread on a similar topic last week:

It depends entirely on which focal range fits you better. Both are excellent lens on the 50D. I tried the 24-105 and then sold it to buy the 15-85. The image quality is very similar, slightly better on the 15-85 in my case. I may have had a poor copy of the L. But either way, get the 15-85 if you need the 15-24mm, which many people do...

My experience mirrors yours: the 15-85 is slightly sharper, has better IS (1 one stop plus panning) and is less prone to zoom creep. However, the 15-85 suffers a little more barreling at the wide.

In general you can't assume that a L lens is always going to be a better choice for you, especially when using a cropped sensor body. This is not to put down L lenses - they are excellent. However, there are some cases where the EFS lenses are better choices for cropped sensor camera use. The specifics vary, but the choice might come down to best functional fit for your use or even to image quality issues.

I have not used the 15-85mm lens so I cannot offer a direct experience-based comparison. I did shoot the old 17-85mm ancestor of this lens on a crop sensor body some years ago. That was a quite different lens in terms of quality, but the functionality is fairly similar. I have used the 24-105 on both cropped sensor and full frame bodies.

Forge the "should I spend more for the L lens" question for a moment and instead think about how you will use the lens and which lens lines up best with your needs. The 15-85mm focal length range covers everything from borderline ultra-wide angle to moderate telephoto on a cropped sensor body. This covers that range that typical one-lens shooters probably are most interested in. On a cropped sensor body the 24-105 covers a range from sort of "wide normal" (equivalent to the angle of view of a nearly 40mm lens on full frame) to a bit longer telephoto.

What this means is that if your expectations are those of a perhaps typical cropped sensor camera shooter, the 15-85mm range is probably more likely to meet your expectations and work for a larger range of photographs. If your expectations are a bit less typical (you don't care much about wide angle, but you want a bit more reach), then the 24-105 could make a bit more sense. For most people the 15-85 is more likely to be a viable one-lens solution and the 24-105 is more likely to leave them wanting a second, wide-angle lens.

IMO, the 15-85mm lens is the best buy for a crop lens on the market right now. I don't know what your intended use is, but I use mine for 90% of my landscape and skiing photography shots. It has great IQ, super-fast focus speed, and is a great range. In fact, I was able to sell my Sigma 10-20mm UWA lens when I got the 15-85mm because it was wide enough to cover most of that range as well.

Here's a shot I always post when showing the quality and usefulness of the 15-85mm. I shot it last year, as the skier was darting in and out of the trees and coming right at me very quickly. I can't remember the last time my 50D missed focus with this lens.

I sold my 15-85 and kept an 18-55 IS and my 24-105. The 15-85 is great, but my 24-105 was slightly sharper and I like to shoot long. When I want small and light, I've never had an issue with the 18-55. Since I am usually shooting full-frame, it just didn't make sense to keep the 15-85.
