Difficult to be sure but it does sound as if it is not properly seated. More due to the lack of positive latch than the darkening. This is common with split image prisms. Unless your eye is precisely aligned with it, one side will appear darker. Less alignment, more darkness. This becomes more pronounced as the widest aperture of the lens decreases. ----------------------------------------- Email sent from www.virginmedia.com/email Virus-checked using McAfee(R) Software and scanned for spam -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
