These pics were all taken @150mm focal length or greater.
i seperated these fro mthe rest as i discovered them to be extremely soft especially when taken with the widest aperture available. Some pics taken at F/8 or greater are useable but still soft.
cos of these pics i have replaced my kit 50-200mm pentax lens with a tamron 28-300 which seems to be sharp all the way through the focal length ... gosh darn it ... i guess i have to go back to Chester Zoo :)))))
