Here is the bokeh comparison between the Canon L f/2.8 24-70 and Tamron f/2.8 28-75. For giggles I tossed in the Canon 50mm f/1.4. I am going post them with letters for ID. You look at them, and tell me which you think looks best, and which you think is which lens. I'll reveal the actual lenses next week on Friday. I think I got all the exif data removed, but if not please don't cheat and look. There is a example of the originals from each, and then 3 100% examples from each. This is supposed to be a bokeh comparison, but one of the examples shows a sharp portion of the photo. It's overcast here today. Normally I'd try for a bokeh test with back lit foliage in the background; maybe I'll get a chance to do that before I reveal the lenses. I used AF, and tried to focus on the subject's right eye (on the left side in these photos). All were shot ISO 100 @ f/2.8 @ 1/500th @ 50mm with a Canon 5D hand held, and received my standard processing. Once again the Canon L 24-70 at f/2.8 was about 1/3rd stop darker than the Tamron at f/2.8, and at least 1/2 stop darker than the 50mm at f/2.8. I evened out the exposure. Batman had crimes to stop, and wasn't very patient with me; I tried to keep things as similar as possible.
