So, are you shooting mostly at 300? Most consumer zooms for Pentax (F100-300, FA80-320 etc) don't do too well up there (but if you are happy with the Sigma, you may be happy with them too). Have you thought of a used Tamron SP 300/5.6? You can get them with a KA Adaptall mount to suit the MZ-50. Mine was about a quarter of your budget from a pricey UK shop. HTH, Kostas
