Thanks for that.

This morning I was running out of time. I tried to link to another picture but failed so then pointed to the one I'd already done.

I think that in order to make a proper comparison you would need two pictures, side by side, same aperture, same b/g distance etc. All I know is that when I moved from the (minolta) 100mm to the (minolta) 200mm I saw a huge improvement in bokeh.

My image above began life as a Fuji Velvia slide. It was scanned at 4000dpi (dedicated Nikon film scanner) then downsized for the web.

It makes a great print, beautifully smooth and wonderfully sharp but the version you see here has suffered very badly from the downsizing. The b/g is very heavily pixellated and the tail is very jaggy. I could have done better but, once again, was in a rush when I posted it. In fact someone (maybe you?) sent me a PM pointing out the pixellation and jaggies . Although it was kind of them I didn't have the time to resize and alter the image.

Later today, when SWMBO isn't looking, I'll try to make a new link to a new photo.
