braindead_fr3ak: My gallery/site is in the watermark in the pictures that I post.
wuszhtag: You were shooting under strong
flourescent light. That is why it looks greenish. Set your WB to Flourescent and do not use flash.
To correct the green tint, pull the green channel down a bit in Levels. If you shoot RAW, adjust the Magenta/Green Tint slider.
Poadster: Go ahead and get the 50mm F1.8. The 50mm F1.4 is only if you need that F1.4 for shutter speed as it does not offer better quality bokeh.
achew: The cats-eye bokeh happens more with full-frame bodies using full-frame lenses at close focus.
ieR: Your example has brightline bokeh (the brighter borders around circles) apparent with the Minolta 50mm F1.7 and Minolta/Sony 50mm F1.4. The Sony 50mm F1.8 DT SAM is cleaner because it is less pronounced.
The Minolta 50mm F1.7 and F1.4 will still produce circular out-of-focus highlights when shot wide open! It does not automatically get
heptagons (7-sides) wide open (you are still very misled here.)

Minolta 50mm F1.4 at F1.4. Cats-eye bokeh apparent on the left and top. Bright-line bokeh becomes distracting next to subject's eyes.

Minolta 50mm F1.4 at F1.4. Bright-line bokeh on the top of the Petronas Twin Towers. Building next to it is distracting also due to bright-line bokeh.

Minolta 50mm F1.4 at F1.4. Again, ugly bright-line bokeh. The highlights should stay out of focus, become
flat like the rest of the background, and not distract you from the subject.

Minolta 50mm F1.4 at F1.4. What catches your attention first? The flowers in focus, or the lights behind?
