Sigma dc macro 17-70mm f2.8-4.5

Hi folks, I read the review on this lens and seen a handful of photos which I found to be rather decent images. I just have a simple question: Is there a big difference between this lens and the SIGMA 17-70MM F2.8-4 DC MACRO HSM CONTEMPORARY ?

I grabbed the older version on eBay at a very reasonable price. I think I will be happy with it, I was just curious if others thought there was a big difference between the two versions.

Hi KevinWE

I own the Sigma 17-70mm F2.8-4.5 DC Macro, bought for over ten years with the Pentax K20D, I still use it with the K30 and K3II,
It's certainly a very interesting lens and with a good overall yield, very good at minimum focal lengths and good at maximum,
it's not HSM like its successors, but if you had it for a reasonable price use it, it's a good factotum.

They are different designs and the reviewers here at PF said the 17-70/2.8-4.0 (C) is better. I like mine and have no regrets. That said, the previous models are no slouches either. Have fun!

You made a great choice,when i find a keeper lens,i always buy a 2nd copy.This is one of those lenses.

Ive read a thread somewhere comparing the 3 versions,cant remember where though.I'll look around and provide a link if I can find it.

The only negatives are no WR and screwdrive but we buy it knowing that, Ive tried it on K-1 as well,the vignetting is right through the zoom range.fine in crop mode or on KP.

Hi Steve,

The reviewers only performed the test on the SIGMA 17-70 MM F2.8-4 DC MACRO HSM CONTEMPORARY they did not make a comparison

and therefore cannot have said that it is better than the Sigma 17-70 MM F2.8-4.5 DC Macro, this is what I understand.

Hmmmmm...from the last page of the review:

QuoteQuote:
Better (optically) than its predecessors
They referenced a previous three-lens 17-70 comparison test in the third paragraph of their review (same reviewers, I believe*) and concluded on the last page that it was the best 17-70 they had tested. At least, that is how it read when it when it was first published in July, 2013 and when I used the review as partial basis for purchase of the lens as walk-around for my K-3, some eight or nine months later.

Sigma 17-70mm F2.8-4 Contemporary Review - Introduction | PentaxForums.com Reviews

https://www.pentaxforums.com/userreviews/sigma-17-70mm-f2-8-4-dc-macro-hsm-c...?reviewid=4705

Of course, none of that reflects negatively on the OP's purchase. A great lens at a great price is always a good thing.

* Back then, I think Ole and Adam were doing most of the reviews.

Hi,
I used to have 3x Sigma's 17-70 2.8 - 4.5 , loved them all , used them all.
Eventually one went to my niece with my trustworthy K-5 years ago.
The second one is permanently attached to my K-30 , still enjoy to use it.
The third one was sold after I have purchased SIGMA 17-70 MM F2.8-4 DC MACRO HSM CONTEMPORARY
Both of those lenses are very enjoyable to use and very good performers.

Hi, Steve,

Now I know there was a comparison between the two Sigma zooms, and since there was no link I couldn't read it.
I answered the question asked by kevinWE, ''Is there a big difference between this lens and the SIGMA 17-70MM F2.8-4 DC MACRO HSM CONTEMPORARY?

No, look at these two reviews, I don't think there are big advantages for both models, but even in the userreview gallery, the score is in favour
of the previous model, but who cares.

Sigma 17-70MMM F2.8-4.5 DC Macro

Sigma 17-70mm f / 2.8-4 DC Macro OS HSM Contemporary

Obviously I couldn't say that there are huge advantages, I've been using it for 12 years and if we exclude the fact that it's not HSM (but also the cost is lower), it's just a matter of habit and dexterity.

Ciao M.

I fully agree, the only problem found on Sigma was, ''not perfect lens centering'', but I think few samples, I read it in some forums,
reason that I generally buy new lenses because I have the guarantee and I can always ask for replacement "except for those no longer produced".

I love the Sigma 17-70 DC. For the money, there is no better choice. The contemporary is slightly better, but at that price I would skip the Sigma Contemporary and get the Pentax 16-85. The 16-85 is also WR and is quite nice. After I bought the 16-85, I kept the Sigma 17-70 DC because of the ability to focus very closely at wide angle; a unique capability in a zoom.
