Hi,

I noticed that in spite of its too small internal size,
KwhyChang mentioned he uses the Rezo 15 with the S90:

Well, he also mentioned he's using the Ridge 30 with it, so I don't know.

I'm looking for the tightest case, which will also give some protection,
(like Case Logic's UNZ2/3 does), but I'm not sure about that zipper.

Here's a internal size list taken from B&H's site:
Canon S90: 2.30 x 1.22 x 3.94"
Rezo 15: 3.0 x 0.9 x 3.7"
Rezo 20: 3.0 x 1.2 x 4.1"
Apex 20: 2.8 x 1.4 x 4.4"
Ridge 30: 3.0 x 1.4 x 5.1"
Case logic UNZ2: 2.5 x 0.75 x 3.75"
Case logic UNZ3: 3.0 x 1.0 x 4.5"

So, has anyone fitted the S90 into a Rezo15 or a UNZ2?
