lenses test pages: help with japanese translation
Below is a link to an interesting page with test charts for all major
50mm lenses out there.
Just for simplicity (to make it easier to compare the K-mount 50's), I put
the Pentax and Ricoh lens charts on a page at

I'm rather surprised by how poorly the FA 1.7 does at wider apertures.
Similarly surprised that the Ricoh 50mm f2.0 did so poorly.

Many sites from mainland China are slow indeed. That is Simplified Chinese btw,
not Japanese.

What's the deal with the A50/1.7?
My favorite 50 is the K50/1.4 - most especially for BW use. Still looking
for a better sample than the one I now have. BTW, Fred, how does the K
compare to the A, IYNSHO?

Hi Godfrey,
I doubt it. The M series was a major redesign from the K, and the look I
get from the K50/1.4 and the M50/1.4 is different.
As far as I can recall,, there was never a K50/1.7, so your comment doesn't
seem right on that point, either.

You're right about the M50 1.7 Shel, it was the replacement for the
[K]55 1.8.
I'm not sure that the M50 1.4 would be called a major redesign, (except
for the mechanics that is),
but all of the tooling had to be changed which along with improvements
in coatings may account for
some difference

If the size, shape, and placements of the elements change, which I believe

Well, I guess they tested just the available-as-new Pentax 50's. The A

Contrast on the K lens is poorer across the board.
