Wide angle lens for Canon 50D

Elle Alevizos , Aug 26, 2009; 08:22 a.m.

I recently acquired a Canon 50D as a birthday gift, with a 24-105mm lens. I also purchased the 100mm macro lens since I do a lot of macro work. I'm thinking that both these lenses cover me for a great deal of what I'll use the camera for - macro, portraiture, and landscapes. However I'd still like to get a wider angle for landscapes. I'd like to know what you guys would recommend in this area. I want an EF lens so that when I upgrade to a FF in a few years time I can take the lenses with me. I'd prefer a Canon lens because I love the way they are built and the quality they give, but if I can be convinced otherwise, then a third party lens would be fine too.
Thank you for the feedback :)

The whole reason for EF-S was to make wide angle lenses for crop sensors, you should really reconsider.
To get really wide on a crop sensor, you need something that starts in the 10mm range. The canon 10-22 EF-S is a very good example of this range.
3rd party lenses that start at 10 or 11mm may be "EF" mount, but they only project an image circle for a crop sensor anyway, effectively making them EF-S.
Not to mention 10mm on a crop and a full frame sensor would be drastically different.
If you want wide on a crop, buy the 10-22, and sell it when you move up to full frame, and then buy a 17-40 or 16-35 EF. But these lenses won't get you really wide on a crop sensor, so don't buy the yet.

I just bought a 17-40mm lens and I've been using it on my XSi. It is wide enough for outstanding shots, and it's way cheaper than de 16-35. The lens build is superb, and the focusing speed is great. That's a good option. I didn't buy the 10-22, or perhaps the 17-55, because I wanted the lens to be compatible with EF mounts, just like you're stating.

If you want to see the capabilities of the 17-40 f/4 on a 1.6x cropped sensor like in the XSi, check this image out: http://authoritee.deviantart.com/art/the-historical-giant-134772355

I'd have to agree. Due to the crop factor, there isn't an EF lens that results in really wide on an APS-C camera.

You might keep in mind the quality of the EF-S 10-22 and it's likely resale value. I have this lens and the image quality is astounding. I'd have to say unless you're looking at going full frame withing the next few months, then this is the lens you want.

I suggest you try a few to see how wide you want to go. I shoot with a 50D, and for me, like Erwin, 17mm is fine for landscapes, corresponding to about 27 mm on a full-frame camera. (I grew up with film and think of 35 mm as wide angle.) But for many people, 17 is too long. Unless you know just how wide you want to go, you could invest more $$ than you need to.

And enjoy your new camera. I got mine a few months ago (also a birthday gift), and I love it. It is a really capable camera, and once you learn your way around them, the controls are remarkably intuitive and fast.

Before yo purchase any of the "S" series of lens...

If you plan on upgrading someday to a full frame sensor camera, the "S" series lenses will have to be replaced.

I had a 40D with the 24-105 and I too did not want any EF-S lenses but in the end I finally broke down and got a used 10-22 that when I went to full frame I sold for exactly what I paid. Get the lens you need now, the canon prices always go up and you will get a good return if and when you sell it.

10-22 ( or some other UW ) and the 24-105 is a really nice combo on a 40/50D.

I have shot with the Canon EF 17-40mm and the Canon EF-s 10-22mm on my 40D. As far as a wide angle perspective, there is no comparison. The Canon 10-22 is the way to go. I understand that you will be switching to a full frame camera. Like others have said, you could sell the 10-22 when the time comes or keep it as a backup for your 50D. The Canon 10-22 is a little wider than the 17-40 on a full frame. Another option would be to rent one and see for yourself. I have attached a photo that was taken with the 10-22. Gook luck and good shooting.

I won't get to detailed about the technical stuff but I have a 20mm that I use as my primary lens for my 5D Mark II and love the thing! I picked mine up second hand from a private party on Craigslist for $200.

You can see a series I shot while camping in the Anza Borrego Desert last week and every shot in here was with the 20mm:

Consider selling your camera now and replacing it with either a 2nd hand 5D or the new 5D II. The 24-105mm you already have, is a superb wide angle on FF, unless of course you want to venture into ultra wide regions.
