So I bought my first DSLR, a pentax k-5 II. I'm working with a Tamron 28-75/2.8, trying to get some action photos to come out well. I've attached two jpegs below (shot with raw, minimal processing in lightroom where I adjusted WB and exposure), one of which is soft/out of focus, and the other is considerably better.
I am working on setting up a focus chart to try to check out the lens/camera, but would appreciate any tips anyone might have for a beginner trying to work out how to take a decent picture.
These are both crops of approximately the same size, I did not include the full size since I don't think they add anything (let me know if that is a mistake as well).
