A lighted tree in our yard in Maine. The sodium lights really make it very yellow and difficult to get a good white balance.

Can someone please direct me to Dustin Abbott's thread about the Tamron 24-70/2.8 VC ? (Looking, but no success.) Thanks.
"On a budget" can mean different things to different people. The first thought that comes to mind when you said wide angle on a budget was the 20mm f/2.8. Although the sharpness is not good in the corners.
Another to consider is Canon's EF 28mm f/1.8. While not as wide as the 20mm, it is considerably better in terms of image quality. It has low distortion, but a bit of chromatic aberration.
The newer Image-Stabilized primes are pretty good but more expensive than the older generation USM options.
QuoteIf you are not using the lens 15-85mm any more, trade it with 24-105L with little top up.
If I could, I would sell the 40D and lens but, my wife wants my daughter to use the camera, so selling it isn't an option now.
I agree that a white box 24-105L would be a great option, a really nice FF std. zoom for a reasonable price.
Assuming the 70-200 is your only EF lens currently, and you don't have the money saved yet for a 24-105, maybe a 40mm pancake would temporarily cover the sub-70mm range until you have money saved up for a 24-XX zoom?
If you buy a 17-40L as a standard zoom for a crop camera now that plenty of EF-s and other crop options are available, well, you're doing it wrong. It's an ultrawide zoom for full-frame.
+1 - and that's the point of comparing it to the 18-55/3.5-5.6 IS kit lens or even the 17-55/2.8 IS. Compared to the 17-40L on APS-C, the former delivers not-too-different IQ and the latter delivering better IQ (and an extra stop of light, a broader range, and IS). Yet, many people recommend getting the 17-40L 'in case you go FF maybe someday,' which I think is pretty foolish unless 'someday' is next month.
Ah yes those people who have a cheap entry level Rebel camera with a 17-40L stuck on the end! Yup I agree, unless your "other cameras a FF" and currently out of action you have no excuse! Too cheap to buy a FF camera but has enough to show off with an L lens! (A cheap one at that!) you're foolin no one son!
Why would you want to do that? The image circle is too small - you'd have severe vignetting.
In any case, there's no adapter and no room for one, since both lenses have the same flange focal distance. You could use a short extension tube, but you'd lose infinity (and even moderately distant) focus.
There are a number of problems I've encountered.
Video focus tracking is SLOW. OK for family groups moving at walking pace. Useless for birds or pets moving erratically and fast. Yet that is when it is needed.
Live view autofocus is slow. The so-called FAST MODE involves exit from live view, autofocus, then retrun to live view. SLOW INCONVENIENT at the least and USELESS FOR WILD LIFE.
A MAJOR FLAW in image processing of hand-held long tele pics. The out-of-focus background is USUALLY renders as streaking from top right to bottom left with replication of detail. Out of focus detail points should degenerate to rather circular blotches but with my 70D the streaking is more common. ALWAYS TOP RIGHT TO BOTTOM LEFT. I suspect image analysis/modification during image stabilization. This is with 500mm lens and 1/750 shutter speed or faster. With the same lens and even with slower shutter speeds this has never happened in 2 years with my 5D Mk II, or many years with my 300D.
Pity. The first photos I took with the 70D were the sharpest I'd obtained, and turned my 500mm lens into 800mm equivalent. The camera is heading back to Canon.
I was having a chat with the manager of a major retail chain outlet yesterday and we had a brief discussion about the 70D.
In short, this is probably Canon's best crop body yet, but the response from the buying public has been very underwhelming; they're sitting on the shelf much longer than expected.
40D is still my favorite Canon, 60D is very good too, but from what I've seen of the 70D you will likely find it a very pleasing upgrade from the 40D in most ways except for a few ergonomic differences.
So who´s buying the 70d if the ISO performance is the same as 60d´s (or a small improvement)?
