Here is a shot of my grandson at t-ball taken with K-x and very economical Tamron 70-300 LD Di Telemacro.
Here is a shot with an added Kenko 1.5 Teleplus converter for more reach. Both from the 1st base fence.
In sunny conditions action shots are not a problem for this combo.
For my granddaughter's softball games that have more action I like using the K-5 with it's faster AF and continuous shooting.
