Pentax's premium DX 200mm — the DA* f/2.8 with Star-tier quality and SDM motor.
The Pentax SMC DA* 200mm f/2.8 ED IF SDM is the star (*) designation version of the DA 200mm f/2.8, indicating Pentax's highest-specification APS-C prime. The asterisk distinguishes it as the premium weather-sealed SDM-equipped version. Compare with id=4640 (DA 200mm f/2.8 ED IF SDM without star).
The lens delivers 200mm (300mm equivalent on APS-C) at f/2.8 with DA* weather sealing at 7 points, ED glass, internal focusing, SDM autofocus, and DA APS-C image circle. Pentax in-body SR stabilisation applies.
The DA* designation indicates the premium tier within the DA range — enhanced weather sealing, potentially improved optical quality, and guaranteed SDM fast autofocus. The 300mm equivalent at f/2.8 makes this a highly capable sports and wildlife lens for APS-C Pentax shooters.
Test SDM autofocus tracking speed. Verify DA* weather sealing integrity. Check ED glass condition. Compare specification against id=4640 to confirm the DA vs DA* distinction from physical markings.
