Stephen your going to need more than 2 . Just looking at your lenses you need 2 55mm, 1 49mm, 2 46mm . Popflash has 55mm in stock right now. i won't shoot without the IR filters , have one on every lens.

 

Thanks so much for the headsup. The 2 free filters from Solms are the E55s. I'm missing the black E49 while I have an extra E55 for the 24 ASPH when it comes.You are right about the E46 for the 28 Cron. The shot above was before I had any filters.

I am a bit unsure, after a number of tests, about the "IR haze"....I think it may really be just a loss of contrast due to IR pumping up the brightness of IR reflective materials, making them closer to other upper midtone picture elements....Sean has pointed out this characteristic, and he even likes it, to increase perceived dynamic range in contrasty situations.

E.g.,in a field of grass, the shadows that separate the blades just aren't as dark due to IR, I think....

But I don't know.

So I use an IR filter for B&W, except on the WATE, where remembering to reset the menu is a pain...

The filter clearly delivers better color results but is it useful to photograph in B&W?...

Pedro--

S Reid mentions that in black & white, removing the filter can actually give you a few more shades of gray.

 

Don't be afraid to try it without the filter!

As to IR colors without the filters: gray-green cloth can go very brown, blue nylon goes violet, brown cloth shifts purple.

 

As to B&W - yes, the IR can provide a bit of "fill light" to shadows (note the reddish shadows in the unfiltered half of the foliage pair posted above), which can open up the shadows in a B&W conversion. OTOH, since I use lower-contrast "Mandler" lenses from the 80s, I usually have tons of tonal range anyway, so I just leave the filters on all the time, and the B&W looks great.
