Input:
I just got this lens to replace or add to my Pentax M 50mm F1.7.  The M 1.7 is a nice quality lens taht produces some fantastic results, but without Auto Focus, it's a little hard to take pictures of children.  Many people say this FA f1.4 is a "little soft wide open" or "Pentax F/FA 50mm f1.7 is sharper wide open"--because of those rumors/posts I was debating on FA 1.4 or F 1.7  I am glad that I bought this 1.4.  I found some examples of images taken at same aperture value, both lenses at F2.0 or F1.8 and the FA 50mm f1.4 is much sharper.  So I don't know why so many people comparing wide open when F1.7 can't do 1.4??? you just don't have that option at all and that is the value I find in this little amazing lens.

I have uploaded a few pics to product image on amazon, take a look... (I am using it with my K-x)
