***UPDATE***
First of all, Thanks all for the replies.
I just did a wedding anniversary event shooting indoors. I used the 35 f2.4 on my K5II and the 50 f1.7 on my Kx. ( BTW, No problem carrying both around my neck for several hours). As expected, the 50 f1.7 delivers even if mounted on a potato body.
I am pleased with the results of the 35 f2.4 on the K5II. I think I'm beginning to understand it a bit better. The raw files from both are not that different, and that is a great sign......
I concentrated the 50 on very thin DOF and close or small details, the 35 for group shots and more general shots.
I like how this is going but by no means LBA has been cured........
Thanks,
