I'm thinking about buying this,
http://www.bhphotovideo.com/c/product/419582-REG/Sigma_669101_17_70mm_f_2_8_4_5_DC_Macro.html#goto_ itemInfo
The reviews are great. Anyone currently using it?
I'm a little nervous that several people complain about its not 2.8 at all lengths. Are the Canon lens 2.8 top to bottom?
It's a shorter focal length but it keeps the 2.8 constantly. And, it is only like $20 more.
tamron 28-75 f/2.8
Which would you go with? It looks like that has more length and 2.8 at both ends.
The ones I linked to, are F2.8 at both ends as well.
Sigma has a 24-70 F2.8, and as you have seen, Tamron has a 28-75 F2.8...both with constant F2.8. They are fine lenses...and yes, obviously longer than the 17-50mm range. However, I find that 24mm just isn't wide enough when using a crop body (any of the digital Rebels or 10,20,30,40D).

I guess the difference is the addition of an HSM focus motor...and maybe something else (I didn't read all the details).
You mean the link I just posted :)
Some lenses are and some aren't...brand has nothing to do with it. It's better if it is...but those lenses tend to cost more and are bigger and heavier.
I would recommend looking at the Sigma 18-50 F2.8 and the Tamron 17-50 F2.8. You would give up some length, compared to that lens, but you get a full F2.8 at all focal lengths.
I was debating between the two, about a year ago. At that time, the reviews that I read, mostly said that they were very close in all aspects...with maybe a slight edge to the Tamron. So I went with the Tamron.
However, Sigma was releasing a new version of their 18-50 F2.8 'Macro'...and it was hard to tell if the reviews were for the new version or the old. The new version might be slightly better than the Tamron...but really, it's a toss up anyway.
Maybe go into a store and hold them both, get the one that feels better.
Tamron is $430
Sigma is is $419
So they cost the same, Anyone know which is better?
By chance do you have a link to the new Sigma Lens?
I noticed the other post with this lens
tamron 28-75 f/2.8
Which would you go with? It looks like that has more length and 2.8 at both ends.
Tamron announced that the 17-50 f2.8 lens will be available for Pentax after 7 th March which is a lens that takes very good reviews. Sigma 18-50 is also ok but as my opinion wait for the Tamron which seems to be better choice (expecially its sharpness is very good).
I have got a :hail: Tamron 28-75mm F2.8

I saw in two different sites the review of this lens, it has good review. One was provided with pictures taken by the user as soon as he bought it, great pictures they are. Also he showed the macro pictures requested by other readers, also great macro pictures. From practical point of view it is worth the money. But I can't remember where the site was.
Oh btw I ask the same question with no answer back then:
