50mm f1.4 or 85mm f1.8

Ah_K, I like your pix. Very nice.

Just to share my experience on 85mm, I love and hate it.
I love it for it sharpness and bokeh. I hate it for it's CA.
Sometimes, a little contrast of the foreground and background, CA turns on straight away.
Very annoying and distracting for me.

What is CA?:dunno:

Thanks megane2.

And Yeah... agree that the CA is evident on the 85mm when shooting wide open. But the problem does start to disappear when you stop down to bout 5 to 6 f-stop.

light - CA or Chromatic aberration is visible in a photo as color (purple) fringing around contrasty edges.

I think it disappear at f2.8. But, I bought this lens to use it at f1.8 not f2.8. :think:
Anyway, it's a good lens. Another grip I found about this lens, I discovered some dust inside,
which is unacceptable for a non-extend zoom.

focus mechanism still moves inside the lens so theres air movement.
dust gets everywhere unless the lens is vacuum sealed from front to back.
