Does the AWB compensate for the thorium color shift or is the UV
clearing on the S-M-C required?
It will try. How successful it will be is another issue.

I agree. However, one of the funny aspects of AF lenses is that they
require no tactile/hands-on for ANYTHING. The "old school" MF lenses
REQUIRE you to put your fingers on them and (IMHO) that is a big part
of what we old farts have come to think of as Real Photography - as
opposed to simply button pushing. (I know there is a lot more to
Photography than focus, but you may get my drift.)
Before I got this one I really hadn't paid a lot of attention to the
differences between the various 50mm f1.4 Takumars. I've now got a
Super Takumar and the Super-Multi-Coated Takumar. Looking at the front
elements, the Super Takumar glass appears more "golden" in color, but
this must be a quality of the coating (reflection) because when I hold
them both up and look through them at my computer monitor (on white)
the S-M-C is definitely a yellow/brown cast (Thorium element needing
UV treatment).
Other than that, the Super Tak is a few millimeters shorter and has 6
aperture blades as opposed to the S-M-C's 8.
After doing some research, I see that there were two versions of the
Super Tak. The earlier version was an 8 element design and is
reportedly less sharp than the later 7 element Thorium design (which
continued through the S-M-C - not sure about the SMC rubber focus ring
version). That's the one I have. You can tell by the placement of the
red IR focus indicator. If it is between the f4 marks it is the older
8 element. Outside the f4 marks it is the newer 7 element design.
Should be fun running some side-by-side tests of these lenses on my
K-x. Does the AWB compensate for the thorium color shift or is the UV
clearing on the S-M-C required?
