That lens does have a stellar reputation, even among f/1.2 lenses from other brands. They're expensive and rare.

"Best" depends on what you want. Wide open at f/1.2 it will let in loads of light, depth of field will be very thin (making it very difficult to focus) and sharpness and contrast will not be optimal. The further you stop down the aperture, to around f/8 or so, the more technical image quality will increase. However, there's no point in buying an f/1.2 lens to use it only at f/8.

Experiment and have fun, see what gives you results that you like in different circumstances.

FYI, in case you're not aware, the lens can be used in aperture priority mode (Av) with the aperture set to the "A" setting. I'd put it there and use the dial on the camera to adjust the aperture.

Don't forget to set the "Enable Aperture Ring" setting to yes in your menu, if you haven't done that.

It's a wonderful piece of glass, very versatile, enjoy using it is the main thing.

Here's a few examples taken with my "Special Lady” Pentax-A 50mm F1.2, the first four wide open @F1.2, second four at @F5.6

It's a wonderful lens. You'll find it has a glow like quality wide open, which can actually be quite pleasing. Play around. It doesn't cost anything to take lots of digital pics.
