LBA is setting in nicely, especially now that I have the K-5. I'm looking to add another lens, budget is about $800 max.
I'm looking at the Tamron 70-200 2.8, Tamron 90 Macro and the Pentax 18-135 WR.
What I want it for: Really looking for a great lens for portraits, taking pictures of my son (due in June), and for birding/BIF/wildlife shots.
I already have 10-20 covered, and 17-50 2.8. The DA 55-300 is a great lens but seems limited for truly great shots (the K-5 might help now with indoor and wildlife at higher ISO). I've been disappointed with it for birding.
The 18-135 I like just because its WR (good for hiking but not critical) and so light.
The 70-200 blows me away as far as IQ, but its large and heavy. And I wonder if the 70-200 range is really ideal for pics of kids (I tend to use the 17-50 more). Using a 2X TC with this would be great for birds too.
The Tammy 90 also has great IQ, and macro interests me but I might not have time to get into macro with a kid on the way
So, what would you do?
