I'm using 500D right now & considering getting a UWA lens.
I might upgrade to FF body in future.
I'm seeing sigma offering 8-16mm, 10-20mm lens, for cropped bodies.
Assumed that i really got a FF body, is there any adaptor to use so that i can use these lens on a FF body in future?
Sorry for this newbie question but i've to think far. (Of coz i know skills are more important =))
