A guy called Falk Lumo has concluded that Pentax' system is only efficient up
to about 200mm focal length. Iirc, he did his testing in the K20-D era.

Well, interesting. I wonder if he knows that you can compare the
difference between Optical and In camera stabilization by mounting a
4:3 Panasonic stabilized lens, (or m4:3 if you prefer to use them), on
an Olympus 4:3 body? Hum, I guess not.
I'm always amazed by experts who don't seem to
I've kind of disregarded those findings. Maybe I'm fooling myself but I
seem to get a better hit rate with the A*300 on the K20D than I ever got
with it on any previous body film or digital. Ok for the record before
digital I used the M*300 much more than the A*300, but they are for all
I thought of that, having just recently used the OIS Lumix 45-200 on
my IBIS E-PM1. (You can get the E-PM1 body now for under $200) As
per urban legend, I turned off the IBIS and left the OIS on.

Gee, I wonder which one works better if I want to put a Takumar or
other classic manual focus lens on the front?

Well, we do have pseudo-quantitative mock three-dimensional colored
histograms based on an ill-defined decision making process. ;-)
Most of what I've read does indicate that lens-bsed IS has an
advantage over body-based IS. However, both do work and IBIS is much
more flexible, not to mention
There are more than 4 basic lens designs, and they are mixed and
matched depending on the lens design. If you really want to know
