Has anyone tried any of the cheaper IR filters that are found on ebay? There's the suntec ones as well as an unbranded one:

At about 1/4 of a Hoya R72, how do they perform? Also, what cut off wavelength would you recommend for general landscapes?

I'm planning to use my 17-40 for some IR shots, there's a gel holder at the back of the lens are there IR gels I could use instead?
thanks!

I don't have experience shooting IR with dSLR, but I seem to recall reading that not all sensors even do a reasonable job of IR photography and many digital cameras have to be specially modified in order to use them for IR (unlike shooting IR film)

You need to give me OK to edit your image and repost! Keep POTN alive and well with member support https://photography-on-the.net/forum/donate.p​hp
