At f16 that becomes 1.58m for the 200mm and everywhere from 4.4m out for the 50mm - the background won't be blurred at all.
By way of further contrast, my 20mm would be in focus from 4.15m out at f2.8. You don't get blurred backgrounds with short lenses!
Discussion Bokeh here. Basically it's the shape and qualities of the out-of-focus parts of the picture.
I'm always perplexed when people who almost always see my name only in print misspell it. Annoys me almost as much as mis-accenting Jërómê's name does him.
But I mean, people misspell principal as principle and lose as loose, so what are you complaining about?
I admit it is almost as annoying to have people call me Meewell even after they have heard me repeatedly say my own name properly. We have met the enemy, and it is us — Pogo
