SIGMA 70-210mm f2.8 APO

I might have the chance to buy a SIGMA 70-210mm f2.8 APO for a very reasonable price, but am having a hard time finding anything about it online.

Clearly it's a mid-90s lens (if not earlier), so no one seems to have any info on it. I've gathered from one forum discussion I found that it is AF, obviously not HSM or anything like that, but as I tend to MF anyway, I'm still interested even if it is only MF.

Basically, if anyone has/had one of these I'd greatly appreciate any info. IQ, CA, performance wide open, that sort of thing... any info welcome.

if it is the same as mine, it is late 1990's early 2000's

I bought mine in late 2003 to go with my *istD

Still use it on my K10D with 2x Sigma APO ex DG teleconverter

Yip, that's the one I'm on about Mike.P or Lowell Goudge (or anyone else who spots this and can tell me), does it AF? What do you think of the IQ? How's the performance wide open?

I don't care if it is MF, I'm just curious. Similarly, I expect there to be a little CA, and I don't expect it to be amazing until it's stopped down a bit. Nevertheless, any info is greatly appreciated before I take the plunge.

Ah, and of course, any more sample pics (or links to them) would also be appreciated.

I don't know the lens, but it might have been either AF or MF depending on mount ordered. A shot of the mount would tell for sure.

it appears there are at least 4 sigma 70-200F2.8 Zooms

this one

Sigma APO 70-200 F2.8

and 3 newer models

Sigma APO 70-200 F2.8 EX
Sigma APO 70-200 F2.8 EX DG Macro
Sigma APO 70-200 F2.8 EX DG II Macro HSM

Did I miss any?

I own the Sigma APO 70-200 F2.8 EX

Dont think so but its the 70-210mm he is asking about

Personally I would take a punt on it if its cheap enough, I have the 70-200mm APO EX and it continues to suprise me.
I was going to get rid of it as I bought the DA* 60-250mm f4 but have decided not to incase I needed something a bit faster.

Thanks for the info folks.

Yeah, I think you're right, if I get it for a good price I'll go ahead regardless. I've attached the pics of the actual lens for sale below. In one pic it says MF on the side of the box, but the only other pics I've found of the lens online have all had contacts on the mount that suggest it might AF. (I don't really mind either way as my staple is an A lens so I tend to MF anyway).

Anyway, clearly it's not a common one as it pre-dates the digital boom. Now it's just a matter of seeing if the price is right

my bad, guess I can't read.

as for the APO 70-200 EX, I agree. I have been so pleased with my lens that I don't see any reason to go for a newer version.

I know it doesn't do macro, but so what, I have a 100mm Macro for that, and also my tamron XR Di 28-75 F2.8 which can do macro.

Definitely a manual focus lens. The AF versions say "AF Zoom APO" on the labeling. From what I've read, this is a very sharp lens and it did very well in comparisions.

I am also pretty sure that it is manual focus. It also is "2 touch" meaning that you have the focusing and zoom ring separately. That would be the deal-breaker for me.

Thanks billx2. Any idea where you read that? I've been trawling the interweb and coming up with very little as far as actual reviews or specs go. There's the odd reference to it, but an actual review would be great.

No different from the way the kit lens MF works, and it hasn't stopped me using it to MF. Zoom first, then tweak focus, and often changing zoom thereafter only requires a tiny further focus adjustment, if any at all. Is that really a deal-breaker?

Some people like one-touch, some like two-touch. I used to like the separate zoom and focus rings much more, but the one-touch design is growing on me with some of my manual focus lenses. Either way works for me though.

Of course not, especially if you are getting it for a decent price.
