Awhile ago I did several lens tests (http://scottbrickertphotography.smugmug.com/keyword/) aimed at seeing how the bokeh looked.

The pics are all stills, shot at either 15ft or 30ft, using a Canon T2i.

The lenses are:
Canon EF 16-35mm f2.8l usm
Canon EF 28-70mm f2.8l usm
Canon EF 70-200mm f2.8l is ii usm
Canon EF-S 18-135mm f3.55.6 is
Tamron 70-200mm f2.8 di ld macro

Focal lengths were roughly 20mm • 35mm • 70mm • 135mm...200mm

The way it works is by clicking on the keyword, all the photos with that keyword will show up. So if you want to compare the Tamron and Canon at 30ft, click on "30ft" and all those pics will appear.

Details per shot are available by clicking on the "i" in the menu to the right of the image.

Let me know if you have questions.

Hope you find it helpful.

Y'all,
I just closed my SmugMug account, so the link no longer works. I hope the pics were helpful.

cheers,
