Thank you.

How about the bokeh?

Last picture. I retouch it on Level because of dim light.

Thank you for visiting us.

That's an impressively sharp lens! Great samples.

This is an AF lens ... right? I had this lens sometime back in nikon mount till i sold it... a pretty nice lens but the auto focus was pretty slow with older Nikon bodies.

Sharpness is excellent, bokeh ? I expect lot better from a 300mm lens. My Sigma 70-300mm APO DG (was cheapest zoom) had better bokeh.

I own the 70-300 APO in both PK and F mounts and they are marginally better than this lens with regards to bokeh. But I would stress on the word "Marginal" here.

Thank you, Richard_D, Attila

Shiladitya, it's manual focus.
