I by sigma 15mm for my 10d....
Yesterday i by the lens and now i start to test in photoshop to defish the image with pano tools and to shoot in all the aperture.My first impresion is very positive,the angle give this lens is very interesting and is easy to defish if the image have a vertical line and i wish to corect.Of course that caind of lens need some period to determaint the corect technic for sooting because of spheric view and also the wide front element that need extra care in strong light to keep the gosting and flare in low level.
