12-24mm F4.5-5.6 EX DG ASPHERICAL HSM

looking into buying this to use as a real estate lens. looking for some solid feedback on this lens from those who own it.


thanks,





--Matt

Could you perhaps update your post to tell us what brand lens you're asking about, and perhaps update the subject so we know that you're asking about buying it, rather than showing us examples of pictures taken with it?

It's Sigma FYI

I saw a nice review on this site.

I agree with the review: if you get a good copy you will like the lens.


What body are you going to use the lens with?

thank you for the nice link it was helpful

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.
