Just to throw an alternative point of view into the mix...
Historically, I'm a bokeh nutcase, and a standard lens nutcase, and I owned both of these lenses simultaneously for a while. But having too many lenses (=too many decisions) meant I had to let one of them go, and I ended up getting rid of the f1.4 and keeping the f2. Here are the things I didn't like about the f1.4, compared to its smaller sibling:
- It's noisy
- It's slow
- It's not as contrasty
- It shows aberrations in the corners
- It suffers more from purple fringing
- The front of the lens extends and retracts every time the camera is switched on. This bothers me when I'm switching on to review images for example, because I often rest the front of the camera on a table etc.
I agree with the comments about the f1.4 having a kind of natural magic, and that's definitely the kind of characteristic that appeals to me, but the fast focus and silent operation of the smaller lens won the toss for me. How could I NOT keep the lens that caught this image...
