Originally posted by ychousa Does anyone use Tamron 17-50 or Singma 17-70 as a main walkaround lens with K-3? I have a few questions.
- Does it work well with K-3? (I saw some reviews that K-3 is picky on 3rd party lenses-not sure if it's credible.)
- Anyone has an excellent made in China version Tamron? Just wondering if Japan & China version have any difference.
- I'm contemplating between Tammy 17-50 and Sigma 17-70. Does anyone have an experience with both and like a specific one?
It looks like Sigma 17-50 is not as popular as those two here in this forum, and my brief experience with it was not very excellent (compared to my experience with Tammy with Canon gear,) so I excluded it.
To answer your questions:
- yes it works fine with the K-3
- I use the made in china version.
- I have no experience with the sigma 17-70, but would not buy it. The 17-50 range allow larger aperture
In this focal range, I have Pentax 18-55, 17-70, 15,21,35,40 limited lenses. Not happy with the AF with 17-70, I purchased the Tamron 17-50 (non VC). The problem is it better than the 15 and 21 limited and no clear difference with the 35 macro and 40 limited. So now I have no use of the limited except the 35 macro limited...
