I have been looking in wonder at some peoples IR shots on here for a while and want to have a go myself.
I was thinking of using my Sigma 10-20 but have read about the central hotspot that some lenses get. Does anyone know whether the Sigma would suffer from this? It isn't on the list that I have seen under either good or bad.
Secondly as I am only going to be experimenting with this the prospect of £100+ for a 77mm filter for the 10-20 fills me with fear (what if I don't like it/can't do it?!). On fleabay there are Opteka ones (http://cgi.ebay.co.uk …ZWDVWQQrdZ1QQcmdZViewItem)
for half the price. Are these any good (please ignore the 'see through clothes' bit of the advert! :rolleyes? Would getting one of these and seeing the results just put me off IR when they didn't turn out very good?
Alternatively are there any other makes which are good (and cheap)?
I am using a 350D at the moment but will hopefully be getting a 20D in the near future. I have read that aside from their inbuilt IR filter meaning long exposures plenty of other people find them fine for IR pics.
My other option is to use a 50mm/1.8 for which I can get a Hoya 52mm filter for about £30. Do you think this would be a more sensible first step? I want to do landscapes/cityscapes which was why I was thinking of using the 10-20.
Okay I've probably typed enough , if anyone makes it through this far then your help or any links would be very much appreciated!
Thanks in advance,
