i have another question, is there any optical difference between the M and the A version?
in lens review section, the M version receives more and higher rating than the A.
just checking out.

I had the A version only for about 25 years and just sold it very recently. It worked well. My only experience in that range is between the M and A 50 1.4's. I kept the A because of the semi-automation of the A. The M was optically the same as were the results. I have had four Tak's of 50 1.4 (3 of them the 8 element types) and only one of them came close (but not quite as "good") to the M or A versions in my static testing results (the 8 element is over-rated IMHO and the 7 element version's yellowing is annoying).
You will love your lens; clear and a workhorse.

thanks jvi
so i think spending an extra 40 bucks for the A to speed up workflow is worth it.

According to info on Stan's Pentax Photography and Pentax Normal Prime Lenses they are optically identical. Coatings may be slightly different. Ratings in the review section are not systematic, and I suspect the M gets a boost because the typical cost is so low its perceived value gets a boost.

I have both (soon). The M was a bonus in an Ebay lot and I'll have to decide which one to keep. Speeding up workflow isn't really the reason I like the A though. I like it because it records aperture values (interesting when evaluating what worked/didn't) and you can shoot in Av mode. It's also nice because you don't accidentally forget to hit the green button...

But I think this is an excellent choice. It's inexpensive and really, really good.
