For me, in term of sharpness Rokkor is the winner, but I like the roundness of Zuiko and its color rendering. The Pentax is also excellent, but it seems like it falls somewhere between the two. Rokkor seems to exhibit rather strong CA (it is also the case with my 200/2). But Zuiko is a bit prone to flare. As usual, I like Zuiko's body finishing and design. It's so nice to handle. Small like a gem.

Sharpness is not everything. I don't like the Rokkor bokeh.

I like the Zuiko best. Use it with a hood and you are there.

The first time I tried the Minolta's older sister mc pf 58mm f1.4 wide open I got this:-

HUH! and another shot wide open for confirmation:-

So is this what F1.4 lenses wide open are like? Well unless I get another make of F1.4 and take the same shot, I'll never know.

Not easy to say anything fmro just one shot, and at small size.

The one thing I notice is that except the Rokkor, the other two lenses seem to have quite some flare weakening the image.
