Re: Infrared filter, which one?

Hi, I like the Hoya R72, (720nm cut off, meaning all wavelengths below 720 nanometers are blocked), gives a nice Wood effect (for Prof. Robt. Wood, first IR photographer) and is not too dark, so AF and AE tend to work pretty well. Also, not as expensive as B+W. I have some IR shots here at
http://www dot johnkennyphotography dot com, many with R72.

Here's a chart explaining "Wratten" numbers which are seen a lot in connection with IR filters.

hi thanks

i have read that the bh 093 is really hard to work with so i prefer a less dramatic filter to work better and easier.

i have read there are some filter for when u use the camera without the ir filter and want the color norma..they are UV/IR block filter. do u know one to suggest?

Re: Infrared filter, which one?

Hi jonny1976, I bought a so-called "hot mirror" filter from maxmax to use for normal photos when the ir blocking dust protector is removed from the SD14 but have found it to be unsatisfactory. No amount of PP gives good results. So I've become adept at removing and inserting the dust protector. It would be great if Sigma would make the IR blocker in an 82mm screw thread, wouldn't it? Perhaps someone else knows of hot mirror that would work.
