Buying a Zoom: Thoughts on 17-70 SDM.

So, after my salacious affair with all things prime, I find I must purchase a zoom. I have a client that loves to throw me into long, narrow crowded rooms and ask for group shots as well as a photo of that guy way in the back. Thus far, my event lens has been my 35 f/2. Beautiful images, but you know how it goes... prime lens means YOUR FEET do all the zooming, and lately that has been a real pain.

Considering the 17-70, but chatter about the SDM worries me just a bit.
What say you?

Thanks in advance!

The 17-70mm focal length is a good choice, but the new Sigma version is the one you'll want to get!

Sigma 17-70mm f/2.8-4 DC Macro HSM Lens for Pentax 884109 B&H

We also have a comparative review of the pentax and previous sigma 17-70mm's if you'd like an IQ comparison.

Well, now...
Thank you! Read a few reviews and it sounds (and looks) great.

I owned the DA 17-70 for several years (before I got the DA*50-135), I really liked that lens and it was very useful - outdoors - as a walk/hike around lens. Indoors, as an f4 lens, I was never very happy with it and preferred to go with others like the DA*16-50 for example. The SDM never gave me a problem either and my only wish for that lens was that it should have been a WR lens. At that time, all the reviews I'd read indicated that for the 17-70 length, the Sigma was the way to go. I've never had the ability to test that personally but I wouldn't doubt it. Not sure if there is a conclusion here but Adam, makes good suggestions.

Thank you blackcloudbrew... and you as well Adam.
I initially ignored the Sigma because the first review I read at Photozone was of an earlier model. But after Adam's reply, it was done.
I'm ordering the Sigma from B&H later today.
Weeeee!

Is the current Sigma 17-70 have better IQ compared to the older one? I know the first version has the best macro magnification, so I'd always assumed that was the one to get.

Isn't it best just to stick with your body's manufacturer for your lenses?

Thanks.

The most recent version: Sigma 17-70mm f/2.8-4 DC Macro HSM is very well reviewed.

No. Pentax makes great lenses, but there are hundreds of possibilities out here - including quite a few that exceed the quality of "native lenses". I have just purchased an Olympus Zuiko 24mm 2.8, had to purchase an adapter as well. I love primes, and this is one of the best 24mm lenses in existence.

Monogamy is not requirement, live a little...

Thanks

If you're speaking of the Zuiko, I'm waiting on this to arrive:
Olympus OM lens for Pentax cameras

If you're speaking of the Sigma, I'll post this weekend.
Cheers!

Not always. Every lens needs to be judged on it's own merits. Sometimes, a third party lens is the better choice in a particular size.

I would not count out the Sigma 17 - 50 2.8 ex hsm fld. I thought I would miss the 50-70mm range but it is just as easy to crop a bit if needed. If you like to travel you would really appreciate the 2.8 as some of the best shots come at lower light levels. It is also really sharp even wide open.
I also had the pentax 17-70 f4 for a short time and thought it was a bit to slow at F4.

Good luck with your decision

Thanks for replying and for the sample image. I don't know why, I have some sort of inexplicable aversion to third-party lenses. But I'll do some investigating. in some cases however it appears that some Pentax-badged lenses are identical to certain third party lenses, spec-wise, on paper. Makes me wonder who actually makes what!
