I would like pros and cons on 24-70 (Page 3): ABC - not that this should make any difference, really - but all Sigma lenses I own (over a half-dozen, now) are all made in Japan...

What is your opinion of Sigma?

ABC - not that this should make any difference, really - but all Sigma lenses I own (over a half-dozen, now) are all made in Japan, whereas the Tamrons I have (just about equal amount) are mostly made in China.

OleMikey - another UHHer - who regularly takes broken lenses apart, and rebuilds them - so - he has first-hand knowledge of this - indicates Tamron makes MOST of the glass for both Nikon and Sony. So, according to him - it doesn't make any difference which BRAND is on the barrel - as it's the same lens, regardless.

And, since Sigma and Tamron lenses are, regularly, a third less than Nikon counterparts, it's all a matter of how much dough you wish to save. Oh, and btw - most Tamron lenses come with a SIX-YEAR warranty!!!!

I know many wedding photographers and they all shoot the Nikon 24-70 2.8.
As for the difference, the main difference is that fact that Nikon makes their lenses from scratch to work specifically with Nikon camera's.
The other company your interested in buys their glass from the lowest bidder (fact) and makes their lenses to work on a variety of body styles.
I have owned and used every variant of this Nikon lens and not one of them has disappointed me yet.

I just came from my local camera store. Wasn't looking for or buying lenses, but did spend a little while with the lens techician. He wanted to show me the new Sigma 40mm f1.4 ART lens. From there we looked at a number of the other ART lenses. What they all seemed to have in common is their size...they are all huge when compared to the most similar Nikkor lens.

The word is that Sigma has a new design philosophy which places primary focus (pun intended) on lens performance, even at the expense of lens size and weight. This makes it much easier to design and build a lens with much reduced vignetting, aberration, and other shortcomings. The 40mm, in particular, is claimed to be an adaptation of a cinema lens, with all of the benefits that come from that.

But there is nothing compact or lightweight about any of these new (and excellent) lenses. They are very interesting, though.

In a previous post I created on the newest version of Sigmas 70-200mm f2.8 lens A uhh member claimed that if your camera gets a new firmware, your third party lens may misbehave. He claims he had to undo the firmware, to get a Sigma lens to behave correctly. Has anyone ever been confronted with this problem?

That is meaningless partial info
blended with total gobbledegook.

Examples:
There is no meaning to "lowest
bidder". We let out bids all the
time, for 10s of thousands and
for billions. There are SPEC's to
be met, dontja know?

No meaning to "glass" either, as
used by you [and uch of UHH].

Absent a side by side comparison of the same subject you will probably never see the difference, and perhaps even side by side. Save the bux! but I have all Canon "L" lenses, we do like to buy toys for our cameras.....sigh..

It's an interesting claim cuz IIRC you cannot undo camera FW updates.

There have been some forum threads begging for a way to do it, but no
solutions found for the problem. The only "solution" ever offered was to
wait for the the NEXT update and hope it fixes the problem encountered
with the recent unfortunate update :-(

Ed, the only Canon EOS lenses I have are the 18-55 IS II which came with my T4i, and the EF-S 15-85 IS USM - which is widely regarded as one of Canon's best crop-sensor cameras. All the rest of my EOS glass, is either Tamron, or Tokina, with a couple of Siggies thrown in. Anyway, yesterday I looked at all of my full digital camera inventory, and was surprised to find ALL Sigmas were made in Japan, most Tamrons were made in China, and that wonderful Canon EOS lens I prize so very much, was, in fact, made in Taiwan!!!!

I'm very happy with my 24-120. See no significant advantage with the 24-70.

Same here. But it does have certain
imperfections which are enuf for the
peepers to shun it. But in real world
use it's a great tool. I do not have a
24-70AF [or similar range] for Nikon
and with the 24-120 I don't miss it.
There's nothing an f/2.8 would offer
me that I can't handle at f/4.0, so it
really covers the water front for me.

Idaho - just looked at the lens test on DPReview's page for the Tamron 24-70 G2 version, and I see it's gotten five stars - which makes it as good as the Nikon one, and slightly better than the Siggie. So, I suspect there's every reason to get such a lens - IF that's your normal shooting range. I happen to agree with you - I think it's kinda short. So is the Siggie 17-70 - the comparable crop-sensor version, which gets a lot of praise. My perfect everyday lens for my Sony a77 II is a 16-105 - which covers moderate wide, and gives you a good portrait length. On my most-used Canon (T4i) I use their EF-S 15-85 IS USM, which covers 24mm on a FF, but always seems a little short. Ditto for the AF-S 16-85 VR I use on my D7100. A much better range is the 16.5-135 Tokina (shown in the avatar) which I use on both my EOS 60D and on my Nikon D7000 (as you can see in the pic - same exact lens - on two different BRANDS of camera.) To me - this lens is the perfect range - gets you into moderate wide, AND provides a satisfactory portrait length.

Yeah, and in my commercial experience, used normally, they'll outlast the warranty. We had hundreds of the 28-75mm f/2.8 Tamron zooms in Canon mount where I worked. Fewer than ten ever needed repair, and most of those were dropped.

Bill … is / was - that a decent lens, or is the 24-70 a few notches above?

Read my Post of February 24th, where one uhh member said he had to roll back the firmware, so that his Sigma 50mm lens would work properly. I won't mention the user name. I've never rolled back a firmware. And wouldn't know how to do it, if possible.
