It had trouble focusing from the very first time I used it. Thought it was strange that a lens at that cost could be outperformed in focusing by a comparable micro 4/3 zoom lens. It will be returned and a new lens purchased. Hope the new lens works better :-)

Just lined up three cans outside. Stood a bit to the left in front of the first one and tried to spot focus on each one (closest to farthest). 24-70 consistently stumbled to focus on any can. Tried it with the Tamron 70-200 and it had no problem with focusing on each can.
Safe to say this is a lens issue and not a camera issue?

Pentax 24-70 Focusing Issues?

Hello, all. New to the group and new to the Pentax K-1 (just purchased one and a few good lenses). I'm not a total amateur but I'm coming from Micro 4/3. Took the camera out yesterday to a city fair and noticed some irregular focus with my 24-70 2.8. Focus was much softer on the left side of the images than the right. I've uploaded some examples.
The daylight photo with the three girls was shot at f/4.5, the Hawaiian dancers was shot at f/4 and the group of young dancers was shot at f/2.8. In each of these photos you'll see far better sharpness on right side, Is this something I'm doing wrong or is my camera/lens in need of repair (bought on ebay).
Thanks, in advance...
PS - I've had far better image sharpness with my Tamron 70-200.
