I am using a K-30 and I want a portrait and macro lens. I'm really in love with the Tamron 90mm SP AF Di Macro f2.8. But of all the pictures I saw online, I 95% of the pictures with the tammy are macro shots. I think I would use macro in less than 40% of my shots. So i am not sure if that is a practical purchase based on my usage. Also the effective focal length on APS-C is 145mm , which is almost a medium zoom and max aperture is only 2.8
So I'm thinking of a portrait lens which can also shoot macro or maybe not. So the lens I'm thinking of are.
Pentax SMC-F 50mm F2.8 Macro (Macro is why I would love this, but not the highest aperture)
Sigma 50mm f1.4 EX DG (The increased Aperture Value is a bonus, but no macro)
PENTAX SMC FA K 50MM F/1.4 (Same reason as above, but Sigma one above it has a silent AF)
Pentax SMCP-F 50mm f/1.7 (No macro, larger Aperture, lower cost - might be able to buy another lens later with more funds)
Can I get some suggestions as to what would be a good option. I'm really confused right now
or should I go with the tammy itself
Btw the current lens that I use is a 16-45 f4 Pentax, its much better than the kit lens, but not the greatest. Might want to look into a f2.8 wide angle later..
