Quick question following on from the recent resurgence of IR images on the forum.

Can anyone comment on the quality of IR shots using a Sigma 17-70 and Hoya R72? Does it hotspot or do images come out OK??I usually use one on a 50mm mkII on my 30D and am getting good results, but would like a bit more flexibility in terms of framing.....

Thx in advance.
