Tamron 10-24 & 28-75 for everyday use?
Hi, I'm considering an upgrade from kit lens 18-55 to two lenses mentioned in title
I found 55mm at kit lens to be a limitation for me, so I would like lens a little longer, ~70mm seems fine to me, options in this range are Pentax 17-70/4, Sigma 17-70/2,8-4 and mentioned Tamron. I put Pentax away from the list first. I very often shot indoors (child) without flash at longest range of kit lens and I have to go with ISO to 6400 which is not a huge problem with K-30, but I would rather stay lower, and f/4 (even at wider end!) doesn't sounds very appealing to me and it is not a huge leap from kit. It is also the most expensive from the three (but marginally).
Sigma is a little better in my eyes, not F/2.8 across the range, but it is capable of limited macro, that is nice bonus. However, I have read a lot of complains about OS draining battery (which is not that large on K-30..) and it is now discontinued and to be replaced by what? I couldn't find any info about successor. The "old" version is still available here though
And the winner in my eyes of the three is Tamron - f2.8 across the whole range, macro, but 28mm at the wide end. So the 10-24mm zoom is a must, but I'm telling myself that I would surely get it sometimes (or right away when spring hits and hikes are on list). It is also nice that both tamrons uses the same filter threads.
I looked at ~1000 images from each lens on flicker, but it is hard to see any difference in IQ at all, but I'm no pixel peeper and I'm pretty OK with kit lenses IQ ATM.
Thank you for any kind of imput
