I upgraded from a Sigma 17-70mm to the DA* 16-50 and I'm damn glad that I made that switch. Here's why:

1. I hate twisting the barrel the "wrong" way to zoom in or out (on the Sigma, vs the Pentax)
2. I need weather sealing and splash proofing because I often shoot in rain/fog/mist/forest/ocean type environments
3. I like the look of the DA* better than the 17-70, and the weight of the camera feels more balanced this way
4. COLOR redition is far superior on the DA* than the Sigma- the Sigma was good, but ocassionally I'd get some weird overbearing yellow tints, the Pentax lens never has this issue
5. Quick-shift focusing mode- has helped me overcome some tough AF hunting issues in failing light
6. IT SAYS PENTAX!

Anyway- the Sigma is a great lens, and that added 20mm length definitley helped- plus the Macro capabilities. If that thing turned the other direction and had the color rendition of the Pentax, I'd have kept it and used both. But I don't have that kind of cash laying around!!
Thank you for the feedback and you are not making it easier for me to stay with Sigma 17-70mm f/2.8-4.5 Macro for longer.

Here is my assessment on why not to ignore the Sigma 17-70mm

QuoteQuote:
  • the extra 50mm to 70mm make this a versatile gem in my book.
  • range in 17-70 beats the range in 16-50 in my use as it incur less lens change
  • you can go wide, normal in 35 to 50, and 50 to 70mm are great for portraits
  • 1:2.3 macro is added bonus not to be missed in this value zoom
  • sharpness is not as good as Tamron 28-75mm f/2.8 but versatility is better in the Sigma due to the 17mm wide angle
  • This zoom is small and lightweight, similar to Tamron 17-50mm f/2.8. It is lighter than the Pentax DA* or the Tamron 28-75mm
  • Build is excellent, I find it in par or better in build than the Tamron
  • MF is weak for the short focus throw. AF is NOT as good as Tamron, a bit slower, it is something to watch but still capable like other zoom to get the job done
  • Versatility is #1 on this zoom. If you like to be a strobist, this lens with a cheap $30 flash will beat the Tamron in both 17-50 or 28-75mm range
  • Rock solid without hearing common lemon problems in DA* 16-50mm or the recent focusing issues on Tamron 17-50 and Tamron 28-75
  • Hin highly recommend this zoom for versatility over the other zooms. The caveats lie in slower AF, slower speed in the long end, actually not by much if you compromise and consider the cheaper cost into the factor.
  • Sigma 17-70mm f/2.8-4.5 1:2.3 Macro Zoom -- Hin's Tech Corner Report
My family went out over the weekend, I only use this lens and while it is NOT a DA* 16-50 with quiet motor noise and has all the great color and speed like the DA* zoom, it has its place in my bag, I especially like its macro, and the range in 50-70 is ideal for portrait and its 35 to 50mm is competent candidate for street shooing while its 17mm give you the wide angle you need for landscape.

Hi, Hinman,

I am also thinking about a similar switch - I have the sigma 18-50mm f2.8 macro, it is currently on my camera most of the time - especially indoor shots with flash. I am thinking about trading up to either DA* 16-50mm or DA 17-70mm f4. I agree with you that 50mm-70mm range is more desirable for a normal zoom.

Since I also have the 77mm ltd, would either one of the upgrades make sense? (nice shots by the way).

Thanks,
Alfred

Hin,
I think you and I think a lot alike when it comes to our lenses, as I've been considering swapping the 16-45 for either another Sigma 17-70 or the DA17-70. While the DA16-45 has been great in terms of IQ, I miss the 17-70 range. I still haven't decided whether I would get another Sigma or go for the Pentax.

While the 16-50 (or 16-45, for that matter) has great IQ, practicality is another thing to consider.

Decisions, decisions...

It is a difficult decision to make. One has to choose the path based on your style and objectives. I have lens overlap everywhere. If I need to pick a zoom to shoot best for portraits, I will pick the Tamron 28-75mm f/2.8 instead and if I go out for spending quality time with my family with need for wide angle landscape, normal view in 35 to 50mm with easier handling due to lighter weight, and a great extra on the portrait, the Sigma is my choice for now until I can justify the expense on 16-50.

There is no clear answer as to one's choosing. I choose the Sigma for the purpose of compromising versatility in focal range and macro over the best in IQ. And I bring my cheap $30 flash to help with the lacking in slower speed in indoor when necessary.

One more bigger print on the Raging sea. I think the Sigma zoom should be considered along with all the other variants with better speed and IQ.

The DA 16-50 like James stated earlier is great for landscapes and is a wonderful lens if you get a good copy.

For me as well its a perfect match for the DA 50-135.. should the latter be in your must get basket

Yes, every time that I visit Jame's pictures on 16-50, I know that is the better lens to get. As of now, I stay unchanged in my decision to keep the 17-70mm longer until I can save up enough fund to justify the purchase. I will re-visit the topic of upgrade hopefully soon.
