Hi there,
So here is my story, I'm sick of the quality of my Canon 18 - 55mm kits lens and am looking for an upgrade.
I've been looking and trying Sigma's as well as Canon's.
I know what focal length I want. (need at least 17mm but realistically want 12mm)
Here's the problem. I'm not sure whether I should get DG/EF lens as apposed to DC/EF-S lenses. THe reason I'm having this trouble is that I know I wanna upgrade to a 5D when I have the money (possibly never) but I feel that if it does happen I don't wanna be stuck with lenses I can't use on the 5D.
Does anyone have any thoughts or been thru the same feelings?
Any advise to help me make my mind up would be seriously helpful!!! |

I don't own a 5D, but I read somewhere that anything wider that a 17mm or maybe it was a 16mm may cause vinetting.
I just read this.
Don't know if this is accurate.
You should do some research.

Vignetting will happen if you use a lens designed for an APS-C sensored camera on a full frame camera.
It's not dependant on the focal length. However, the quality of the lens will come into play. Cheaper lenses may vignette at the wide end.
I use the 17-40 on my film camera without issue. |

I simply love my 10-22mm. Yes, it will only work on 1.6 crop sensors but when are you planning to buy the 5D? If you won't upgrade for another 2-3 years, the purchase of the 10-22 would be worth it. If you never upgrade, then the 10-22 will be worth it. This lens is amazing and really is my favorite. Just my 2 cents.
Also, I recently purchased the 40D and I have no desire to upgrade to a FF camera. The 40D is amazing and I see no need for FF (for me anyway).
Anyway, you will not regret buying the Canon 10-22mm EF-s unless you upgrade to the 5D really really soon and even then you could sell it for close to what you paid...
Let us know what you decide. |

| Canon 10-22 is a great lens, Buy it, use it, enjoy it. If some day you go full frame, you won't have problems selling the 10-22. I sold mine within half a day of posting it I believe. |

The Sigma 12-24 is supposed to be full-frame compatible, although some people have reported vignetting. If you shoot RAW, this latter should be fixable relatively easily in Lightroom, to name but one.
I found the one of these that I had to be really sharp and certainly well put-together. Just about the widest rectilinear you're going to get for FF at the moment.

Thanx for the input guys.
Slickchick I hear you about the time frame that I'm looking to upgrade. It would probably only be in 2 years or so and I was looking on eBay and I see that people aren't having issues selling their equipment on the site. I'm thinking of maybe even getting a lens off of there too. I'm worryied about a 2nd hand lens' quality however.
Mr_Pants thanx for the mention on the Sigma 12 - 24mm I was looking at this earlier. Have you used the 10 - 20mm from Sigma as well? I've used the 10-20 and it was out standing and if the 12-24 is the same quality I would seriously consider getting this instead :)
Man_Called_Horse, I have done a lot of research and am aware of the vig of a DC/EF-S lens on a fullframe camera, that's why I'm needing advise :)
Routerguy666 I'm glad to hear you didn't have any trouble selling your lens this def helps to know! |

I just don't think you save very much money buying secondhand lenses. I have been looking at some lenses and the final selling prices on Ebay have not been much savings. I'd rather pay $75-$100 more and get a new lens.
I'd post a WTB ad in the Buy/Sell Forum here and see if anyone wants to sell what you are looking for. I have had nothing but positive transactions with people at DPC and sometimes you can get a good deal.
ETA:
If you bought a Canon lens, it would keep its resale value better than a 3rd party lens...just something to keep in mind.

Monique having used one (twice) it's fantastic, you really can't go wrong with it in terms of quality.
I've used the 17 - 40 and 24 - 70 (canon L glass) and it's just as good as those to be honest.
Slickchik - thanx for the info about the forum and the branding, I will keep that in mind!!! |

there are a couple of types of vignetting:
1. mechanical vignetting, which may be caused by too many filters screwed onto the lens, a too-long lens hood, or using a DC lens on a FF camera (or by other things).
2. Optical vignetting. This is just a slight darkening in the corners. Some add this to portraits to draw attention to the center of the image. Its not always bad.
3. Pixel vignetting (or whatever its called) -- photosites on the camera sensor are supposed to have "wells" with steep walls. At the photosites at the edge of the sensor, the light will be coming at an angle, while the sites near the center will have the light coming straight on. The result is similar to optical vignetting.
The sigma 10-20mm would mechanically vignette on the 5D if it worked at all. You would see the image circle cast by the lens, surrounded by a black border.
The Sigma 12-24 optically vignettes on the 5D, but you get a pleasing image out of it. |
