Hello there,



Does anyone of you have experience with the Tamron AF SP 70-300mm f/4.0-5.6 Di VC USD(how do these guys come up with does names) for Canon 5D?

The name is not so strange.... Lets compare it to the Canon EF 70-300mm f4-5.6 L IS USM.

Brandname: Canon / Tamron

Auto focus: EF / AF

Full frame: EF / Di

Focal length range: 70-300mm / 70-300mm

Aperture range: f4-5.6 / f4.0-5.6

High end range: L / SP

Image stabilization: IS / VC

Ring type motor: USM / USD



All in all, not a very good example of lenses with ridiculous "names" <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='' />.

I am looking for a telezoom or fixed-focal >300mm or >400mm for my EOS 5D (I). I don't have the budget for a Canon 100-400mm lens. Besides that I think it is a very awkward lens as well.



I came acrosse a Tokina 80-400 as well, but couldn't find a test for it.



Hope to hear from you.



Best wishes,

Some have problems with focussing accuracy towards infinity on the Canon mount. For the rest I have not seen any deep insights into the workings of that lens in the field yet, on Canon.



The Tokina 80-400mm is not really great, I would rather get a Canon EF 70-300mm f4-5.6 IS USM. But still, if you stop down to or past f8, the Tokina can get decently sharp at 400mm (and sharper if you only go to 350-380mm). But f8 at 400mm (for decent results) and no IS, definitely a good weather lens.

The Sigma 120-400mm lens is not amazing at 400mm, but apparently bit better than the Tokina. And it offers IS (OS).

And of course there also is the Tamron 200-500mm which is relatively affordable, and has quite impressive optics (yet no IS).
