If you search online, you will find sites where people have measured the problem. Basically, you create a static setup with your camera and a target (usually a measuring scale) focus clearly on one part of the target (a specific number on the scale) with a wide aperture lens for reduced DOF and see if the resultant image agrees with what you see in the viewfinder. It might be worth obtaining a VF aid to magnify what you see, for greater accuracy. So, on a metric scale, you might focus on 10mm. When you look at the print/monitor, you find that the image has a focus on 10.4mm (it being further away from you) and you can say that the camera backfocuses. Oddly, it may misfocus at different amounts with different lenses. Or not at all, with some. There is a documented way of accessing the firmware in the Pentax DSLRs to adjust (unfortunately, by trial and error only) the problem. Or you can send it in under warranty or throw money at it. ----------------------------------------- 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.
