I've been struggling to find a replacement for my lovely Pentax-A 50:1.2. I still have it, and I don't mind playing with MF once in a while, but sometimes MF is frustrating, especially with moving kids.
I tried the FA 31mm Ltd but at anything lower than F4, the 50/1.2 wins in terms of sharpness, contrast, and bokeh. Especially at f2 (which I tend to use a lot), the 50 is tack sharp, while the FA 31 is still a bit soft (yes, I'm pixel-peeping, but that's because I'm spoiled by the 50/1.2). Don't get me wrong, the FA 31mm is a wonderful lens compared to others such as the FA 35/2, DA 35/2.8, etc. But it's just not as great as the 50/1.2. In fact, I prefer the images coming out of the FA 43/1.9 than the FA 31/1.8.
My question is: Which other lens should I try? I need an AF lens that is tack sharp, has excellent contrast and bokeh at F2. Focal length should be equal or shorter (not higher) than 50mm. I'll be selling the FA 31mm to fund the purchase of this new lens (keeping the FA 43)
