If anybody has this lens can you tell me do the earlier versions clearly show APO on the lens itself?

I'm just curious as My lens says Sigma DG in Gold but it doesn't say APO or DG near the white print which is very different from the pictures Sigma has. Of course KEH sold me the lens as an APO DG so I would like to verify that it is in fact an APO DG before I return the lens.

But both of those lenses look completely different from the lens I have.

Just went to the sigma site there is an APO and a non-APO version see
links below. Sound like you have the non APO version.

For what it's worth my 70-200 eg dg definitely has APO printed on it,
I do not think that sigma would leave it off.

Cheers

You might want to try e-mailing Dragon (alephone) you know the guy that had pics of people water-skiing on the St.Lawrence River in yesterday's posts..he has the older APO f2.8 non-Macro...you could check with him to see what it says on his lens. Maybe they didn't write APO on it. Worth a try!
Anyway Dragon can be reached by e-mail if you check his profile. Good luck Pete!

All the best

Thanks anyway, I'm just looking for a Sigma 70 - 300 APO to tide me over until the 70 - 200's get more reasonably priced.

Yes, all generations of this lens have APO and non-APO versions, and they are clearly labeled as APO if and only if low dispersion glass is used.

If your lens does not have the APO label, it isn't the APO version.

Are you positive of this? I just want to make sure before I raise sh*t storm on the KEH phone lines!

I bought a used 70-300 from Henry's here in Canada which was labelled as the APO version, after looking it up on the net I realized that it was not the APO version(they are clearly labelled as such according to another photo. store as well) I returned it to another Henry's and they also confirmed it had been mislabelled and gave me my money back.

Sigma 70-300 APO DG macro is nice lens also, and good value for money (like Tamron 70-300). I'm not so sure about Tamron's better quality & sharpness ;-) Both lenses needs to be stopped down to f/8-f/11 to get better sharpness (at 300mm).

I just got this lens and it definitely says APO DG on it and has a red ring. From my test shots so far, it seems just as sharp as the Tamron and does not suffer from the horrible purple fringing I've seen in pictures taken with the Tamron. The build quality also seems good, so I can't see why anyone would complain about that. If you don't want to have to do a lot of post processing I would definitely recommend spending the extra $50 on the Sigma.
 
Hi,

I know four different version of that Sigma 70-300 lens:
  • APO ver.
Sigma 70-300 F4-5.6 APO Macro Super II (Discontinued)





Sigma 70-300 F4-5.6 DG APO Macro


  • non APO ver.
Sigma 70-300 F4-5.6 Macro Super II (Discontinued)



Sigma 70-300 F4-5.6 DG Macro



Happy Shootings!

...It seem that brand new Sigma 70-300 lenses has different prints (in gold) also:
  • APO ver.
Sigma 70-300 F4-5.6 DG APO Macro


  • non APO ver.
Sigma 70-300 F4-5.6 DG Macro

From direct test lab comparisons, the Tamron is easily sharper especially at 300mm. There seems to have been a few examples of the lens that had more purple fringing than most - and those people post a lot. Mine, and many others have no problem with this. When I had the Sigma, there was dark green fringing that I don't have on my Tamron. If someone has a Tamron with bad purple fringing, return it. Get a better copy - its guaranteed.

Optically, there are more lines/LPH resolution for the Tamron at all focal lengths in all tests. The lightness, and build quality backed by 6 year warranty are worthwhile as well.
 
I have seen non-APOs with the red ring, friend has a DL Macro Super and her's has the red ring...

My 2 pence worth is if it doesn't say APO then it probably isn't....

Do you have a link to these "direct lab test comparisons"? I did a lot of research on both lenses before deciding on the Sigma and came across no such thing. The closest I found to that was a comparison of the lenses on two different mounts and I've read that tht cannot be taken as a fair comparison due to different rating systems for Canon and Pentax. Do you have any direct proof that the Tamron has more resolution?

Also, I've noticed no green fringing on my APO DG model, but I have heard of non-APO models suffering from it, perhaps you were unlucky like the many people who ended up with the extreme purple fringing on their Tamrons.
