I totally concur here. I'm in the middle of Galia's and mine trip to
USA and even in Chicago I could get good pictures with 33mm lens of my
Ricoh. The 50 mm equivalent focal length is extremely versatile.

I diagnosed myself with having an astigmatism while in the Navy in 1965, off
the coast of Vietnam. I noticed a difference in the lines of a bar-code when I
was sitting up or lying down at about 15 feet from the cardboard box. It has
only gotten marginally worse 47 years later.

Well, just to follow-up on my earlier stuff I was making a big error.
Exmor does not equal Exmor-R. The APS-C sensor is the plain vanilla
Exmor (not the backlit Exmor-R technology).

Bad form to reply to oneself, but since I'm mostly talking to myself
here I pass this along just to be complete.
: )
I found the following illustration of how sensors were always
discussed pre-Exmor. A lot of people still discuss them this way,
throwing them all in the same "bucket".

ROFLMAO.
FA lenses don't have the edge sharpness that the DA lenses deliver. They're
not engineered to work with a sensor, and it's obvious in the results.

The SMC P 135mm f2.5 has been called the poor mans A*135. I have never
even seen a A*135 but I have one each of the 135mm f2.5 in K and M42
(SMCT), and I can attest to their excellent imaging qualities both on
film and digital. I was able to get them quite inexpensively mostly

Never found it to be less sharp than any zoom, the only zoom I used
