The Tokina with the variable diaphragm and the Sigma with the shorter focal
length range are being discontinued, so you could maybe get a good deal on
them. The Tokina 2.8/28-80 and the Sigma 2.8/24-70 are the current models.
I personally still believe that the Tokina lenses are better made than
Sigma. In addition, I would be hesitant to buy such a fast lens with a 24-70
zoom range, because that would really require an excellent optical
construction. Thus I would go with the Tokina 2.8/28-80. Be sure to check
out the lenses at your local store. Maybe the Tokina seems too heavy and too
slow and noisy in focusing to you.
Maybe you get the chance to test the lenses with slide film at your photo
store. I would especially test them for distortion at the short end. Also
make sure that they carry the newest chip sets so that they work together
with your camera body.
www.photodo.com do independent MTF tests at the Hasselblad laboratories.
They gave the old Tokina (2.6-2.8/28-70) a score of 3.1 (out of 5) and the
old Sigma (2.8/28-70) a score of 3. For comparison: The Canon 2.8/28-70 got
3.9, the Nikon 2.8/35-70 got 3.8.
Cheers,

Hi Morten,
Of these I would strongly recommend the Tokina 28-80mm, although the
earlier Tokina 28-70mm is also a fine lens. The 28-70mm is based on a
very fine French Angenieux design, but Tokina have managed to extend its
range *and* improve its optical performance in the 28-80mm.
In terms of optical performance, it is up there with the camera brand
"pro" lenses. It's also very well built. Sharpness and contrast are
excellent, distortion is very low and the flare resistance is first rate
for a zoom lens of this range of focal lengths.
The Sigmas have a warmer yellowish colour rendition that is close to,
but still slightly warmer than Nikon lenses whereas the Tokina has a
cooler rendition that is closer to Canon's. The only downside to the
Tokina (IMO) is that it lacks the Sigma's HSM motor which allows faster,
quieter focusing on Canon EOS and late Nikon AF camera bodies. The
Tokina is surely fast enough for >90% of photographers.
I think you should also consider brand name lenses from the company that
made your camera, but you didn't say what brand that is.

maybe?).
Morten consider the brand zoom in this range. Sigma and Tokina are cheaper
than any 2.8 brand zoom. If you don't need 2.8 f-stop consider slower zoom
in this range. Some companies have great lenses in 35-70 range or 28-1xx.
Get one of them, fixed wide angle lens (24 or 20) and fixed 85, 100 or 135
lens or maybe a macro 90, 100, 105 or 200 lens.

as long as the equivalent or near equivalent Tokina. I have found (to my
cost) that even Sigma EX lenses fall down on durability of construction.

Maybe they're OK for amateurs who baby their lenses ...
... or maybe not!

While I cannot give any opinion on the other lenses, I would like to vouch
for the Tokina 28~80/2.8 ATX-Pro as a superb lens. I have it in Nikon mount
and on my F90x it focuses pretty fast, probably due to the very short throw
from infinity to MFD, about 90°. The AF/MF switch mechanism is a joy to use
(you pull back on the _wide_ focusing ring to engage manual focus). As it
has been mentioned, distortion is practically nil and resistance to flare a
source of envy to prime lenses. I shot it extensively against the light
during a recent trip and the results really amazed me. Let me add that
although it's heavy (probably weighting as much as four prime lenses in 28,
35 50 & 85mm), the convenience is really something to consider, specially
when the results from the zoom compared to said primes is virtually
undistinguishable.
I hope this helps.

I also have the Tokina 28-80, and love it, but I have found that it has a bit of pincushion distortion at the long end...
Its very sharp though.

I hope so too.

I just found the Tokina 28-70 PRO II in top shape used for a reasonable price I think so that's what I'm going to buy.
I went to a shop and 'felt' the Tokinas and Sigmas, and the Tokinas are definitely more what I like. I know the Sigmas might be slightly better in the optics, but definitely not in mechanics.
Then I'll wait for a bargain on an ATX 280 PRO later.
Sincerely,
Morten H Pedersen

I don't think you'll regret this decision (especially of the price is
good). I have this Tokina and it's a very nice lens. The only real
drawbacks are its size/weight and the fact that 77mm filters are a bit
pricey. But you'll also be able to use the filters on the big, heavy
80-200/2.8 that you'll be lusting over and eventually purchasing
before long! (Ask me how I know...)

Even the cheapest junk lenses work well on a cheap digital SLR.

Nobody thinks you are smart or endearing with your constant whinging about
others' opinions or equipment preferences. You are just a baseless nutter
who actually deserves no further conversational effort. It's like arguing
with a Nazi. Oh yes, I nearly forgot...you are a Nazi.
Goodbye.

I've met a lot of people from the 'Net and whether they've been nice or
naughty on the net, they've been pretty decent in real ife.
I get the impression things would be different in your case, however.
Tell me, what age are you? And why do you have an obvious hatred of
anyone you consider "beneath" you?
