Sigma Zoom Telephoto 70-300mm f/4-5.6 APO DG Macro Autofocus Lens ???

Hey Guys,

what do you guys think about this lens ? im in the market of picking up a reach lens. when i traveled to cape cod last week, i had some shots where i needed a reach to capture the light tower and such .. please let me know if this lens is worth getting ... or if there's another lens worth saving up for .. thanks a bunch guys !

or maybe this one EF 70-300 F/4-5.6 IS USM ? i've read alot of good reviews on FM and everyone seems to like the lens compared to the 70-200 F/4L lens too

what do you guys think ?

I really enjoy mine(Sigma 70-300). The new Canon 70-300 IS looks nice, but for the price(3X the Sigma) you're not getting much more besides IS. No full time manual focus, front element turns with focus which makes using a CP filter harder. The Sigma doesn't have these features either, but it's not $550.

See this thread: https://photography-on-the.net …&highlight=sigm​a+70-300mm

Maybe someone who has used both can comment in image quality.

The Sigma APO DG is the only longer zoom worth having below the Canon 70-200 f4 and Sigma 100-300 f4 in my opinion, if you're interested in performance and value. Any longer zoom needs a monopod or tripod to give its best. If you try and handhold at 150mm plus you may find images a little blury.

At f/7.1 or above, this Sigma 70-300 is sharp enough.
i dont think IS is needed if you shoot at ISO 400 or above in normal light.

here are few shots with Sigma APO 70-300

wow .. nice pix ...

and thanks guys for the advice ...

does anyone know if a canon EF1.4x11 extender will work on this sigma lens

No it won't work on this lens. even its not supported by Sigma's own TC.

But Tamron TC works with it.

I owned the Sigma 70-300 for a while, before I got my 80-200L. It is a decent lens for the price, but it does have its shortcomings. It is a very slow focuser, and is soft unless really stopped down from 220-300. Other than that, it's a good lens, and arguably the best of those in its range and price.

That said, the new Canon 70-300 IS blows its socks off in terms of sharpness, focus speed, and of course IS. But, it's 3x the price too, so you pay for it!
