| Latest Review Posted | Tamron SP AF XR LD Aspherical IF Di II 17-50mm F2.8
It's about time to do a review about this lens. It was the first lens I owned after the kit lens and it has been my all around lens since 2012.
Sharpness
Let's begin with the best part, Sharpness. This lens is a absolute beast at sharpness when mounted on my K-5. Very consistent across all the frame and all the focal lengths with a bit loss in 50mm. Even wide open (F/2.8) it produces very crisp looking photos becoming better and better from F/4 to F/8.
Versatility
As I said, this is been my all around lens from 2012. Most of my shooting consist in family/friends portraits and lots of landscape and nature photography. I found my self using it all the time because of it's useful focal length and fast aperture.
Auto-focus
The auto-focus is great in good light, very fast and reliable. Just don't depend on it to focus in low light or Sports, I've tried to photograph Handebol Indoors and it struggles to nail focus even with slow movement. It will do the job in birthday parties or holiday celebrations indoors but be aware of its slower AF speed in this conditions. It will nail focus but with hunting.
Chromatic Aberrations
Well when I begin shooting with this lens I tend to use it wide open all the time even in bright sunlight doing street photography. You can see some CA at F/2.8 especially at 17mm but nothing compared with the Pentax DA* 16-50. Very easily corrected in LR with default correcting settings. Mostly purple and green in very contrasty areas.
