That's what the simple math would imply. I doubt that the lensbaby
optical designs are complicated enough to alter that.

I was working with the trusty Pentax 6x7 today and put on the Lensbaby
3G that I bought for it a while back. The lens baby uses a set of
apertures that are just steel metal rings held in place by magnets in
the lens. To my horror, I was unable to find the aperture kit anywhere
in the bag. It appears to be lost for good. All I have is the 5.6,
which was in the lens. At home, I tried one of the aperture rings from
my Pentax K Lensbaby Muse. The f2.8 ring for the Muse is exactly the
same size as the f5.6 ring for 3G. The Muse is a 50mm focal length,
the 3G is 100mm.
So - am I correct in assuming that is the Muse f2.8 ring is the same
size as the 3G f5.6 ring, the two stop differential applies to other
aperture rings? So Muse f4 = 3G f8, Muse f5.6 = 3G f11, etc... I
assume that they logically would have to be consistent, but maybe the
world is not so orderly...
The 3G for medium format has been discontinued for some time but
replacement rings for the Muse are available. I ordered a set hoping
to relabel them for the 3G, at worst I'll have backup for the Muse.
Thanks -

Don't lose heart! They might want to cut it out, and they'll want to avoid a
