Step Up Ring (from 37mm to ??)

I've been playing around for a year or so with the Hoya RM90
IR pass filter on my Sony DTR-320 and want to get a second
filter now (a Hoya R72).

The ring size on my camera is 37mm. The RM90 filter has a
37mm threadsize, but I haven't been able to find any R72 filters
in that size, so I'm planning on buying a step-up ring.

Is there any size above 37mm that it would be better to step up to
over another. I was just going to go with 46mm since that's the first
step up, but wanted to check to see if there's any reason to another
size (like it'll be easier to find things that fit 49mm or 52mm than
46mm). Thanks.

49 and 52mm filter are quite common. You should have little problem finding
what you're looking for in either of those sizes.

Beowulf,
you basically answered your own question here with your last
statement. As a previous poster said "49 and 52mm filter are quite
common", B&H lists the HOYA R72 @ the same price of $39.99 USD for
both sizes, so I would get the 52mm filter & a 37-52mm step-up adapter
ring as it will fit more lenses down the road if needed & the price is
the same.

Be advised that the HOYA R72 is a near infrared filter which
actually lets a very small amount of red light to pass through it, but
for most applications this is not a problem & can even be a plus. I
have this filter & it works great on several digital cameras that I
have used it on. Some people like the "false color" effect but I
almost invariably convert all of my NIR pictures to grayscale (B&W) as
I find them more interesting that way. But this is just "my"
preference, feel free to use any effect that "you" like.

Are there any issues with going up that big a step with a single

I've been taking photos with a Hoya RM90 for a year or so now and
have enjoyed using it, but I want to get a more permissive filter now
since in some circumstances it is difficult to get good exposure with
the RM90.

Do the pictures actually come out tinted red or is it more like a
false color pic?

Yes, it's more obvious & a bit more prone to lens/filter flare
so a lens hood whenever possible is always wise. Additionally you my
wish to order a generic lens cap of the proper size of your new filter
if you intend to leave it on the camera.

That depends on the video or digital still camera it's used
on. Most Digital Still cameras tend to generate some type of false
color caused by many factors such as the quality/type of infrared
block filter used, CCD or CMOS sensor characteristics & auto or manual
white balance programming, jut to name a few. I thusly always shoot
both digital still & video taken with a HOYA R-72 NIR filter with the
camera set to B&W mode if it offers that feature. If not, any false
color can be post edited out simply by color de-saturation or
conversion to B&W/Grayscale.
