Typically when forum members provide help with lens choices, it is very helpful if we know with what body you plan to use your lens. For instance, if you are planning to use the Sigma 12-24mm on a 1.6x FOVCF (Field of view crop factor - 7D, 50D, Rebel T2i, etc.) camera, the 12-24mm would provide a totally different field of view than when it would be used on a full-frame camera like the 5D Mark II or 1Ds Mark III.


In short, this information helps us better help you. We can give you more relevant information that will help you make informed purchase decisions.

ok so tell me. how does changing the body change the lens? I mean what
would the difference if I had a 5D mk.II verses say a 50D?

If you have a crop, you will get lots of folks telling you to get the 10-22 EF-S lens instead. If you have full frame they may tell you this lens is fine.

On a full frame body (eg 5DMkII) this lens is truly 12-24mm 4.5-5.6


On a APS-C body(eg 50D) this lens will be roughly equivalent to 19-38mm 7.1-9.0 (1.6 x longer and 1 1/3 stop slower) , so it will give you still wide but significantly narrower angle, and greater depth of field.

both of those comments are totally irrelevant to what I asked. I wanted people to tell me what they thought about the lens not the conversions and not if they thought another lens was better for me. Honestly unless you have a link to a good review or have actual experience with this lens you have no reason to post on this.

Matt, focal length conversion factors play a big role in a lens' versitality. The difference between 12mm on full frame and 12mm on a 1.6x FOVCF body is very significant, and the different perspectives achieved by using different bodies will directly influence the lens' functionality for your style of shooting.

[Matt.s.Maneri]

I didn't ask if this will work good for me. I am capable of making decisions like that on my own. I asked for solid feedback on what people thought about this lens. Example is it sharp, is CA bad/good, is Vignetting bad/good stuff like that. If I said hey guys do you think a 12-24mm will work good for shooting landscapes? then maybe but the simple fact is that focal length has no effect on what I asked and even if It did 12mm is the widest non fish eye you can get for canon so unless I asked will this lens be good for shooting birds or sports camera body factor's in 0% to my question

WOW!


Edited...I think I may have been ignorant with the previous reply of mine, hence the edit.


I'm afraid you just need to be a little more cosiderate of others, as there are plenty of posters herethat may take offence to the 'tone' used.
