I am deliberating between this and the tamron 70-300 vc. I do not have the money for the IS version <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/sad.gif' class='bbc_emoticon' alt='
' />. I will use the lens mainly for action shots of my three year old, my husband playing football, wildlife and portraits/candies. Will I struggle hand held at longer focal lengths. I have a speedlite which should help in lower light.
How do they compare in iq, AF speed and accuracy, bokeh?

Tamron 70-300mm USD VC
- AF tracking speed: ok-ish, not overly fast
- AF accuracy: Should be good
- IQ is ok, quite good.
- Bokeh: not the most smooth but quite agreeable.
- Blur: its an f5-5.6 lens at the long end, so don't expect miracles.
Canon EF 70-200mm f4 L USM
- AF tracking speed: very good.
- AF accuracy: Should be good.
- IQ is very nice.
- Bokeh: one of the most smooth bokeh-ing zoom lenses.
- blur: its an f4 lens at 200mm, Quite good but do not expect miracles (depending on subject distance).
- You can add a Kenko 1.4x TC to it, which brings it to a 280mm f5.6.
The Canon seems a bit better suited for moving subjects. The Tamron with its bigger reach better suited for wildlife (of course, the Canon makes up for than with Kenko 1.4x TC which is quite affordable).
Now for an outsider:
Canon EF 200mm f2.8 L USM II
- AF tracking speed: very good.
- AF accurancy: very good.
- IQ is great.
- Bokeh: quite agreeable and smooth character.
- Blur: a lot of it in comparison, because it is f2.8 wide open.
- You can add a Kenko 1.4x TC to it, which brings it to 280mm f4.
The Canon 200mm f2.8 is well suited for moving subjects, like the sports you mentioned. With Kenko TC it will have the reach the Tamron. Its great for portraits (provided you have the distance to the subject).
All in all, I can not make the choice for you, nor make it much easier. The 200mm f2.8 has the advantage of f2.8 and fast AF. The Tamron gives zoom flexibility and VC (low light portraits and other non-moving subjects). And reach, for the lowest price. The 70-200mm f4 sits in between. Tough choice.
