I like the grip. As for the whole VPN being caused by the grip thing, it's a load of BS. I've had it occur with & without the grip. ----- This hasn't been discussed in a while. The sensor (or the sensor plus the Nucore A/D converter) apparently produce vertical pattern noise in all sensors, but only a few people find it noticeable, and only at high ISO. But it is there. I've seen apparently clean images dissected to show that, indeed, VPN is present, just not noticeable. The grip apparently produces (or can produce) a different problem, called horizontal pattern noise. I'm not a grip user so I have no experience with it. Again, though, this doesn't seem to affect everyone, or at least not everyone notices it. I haven't seen posts on it in a while. I don't think it has been established whether every sample of the grip produces this, but most often unnoticeably, or whether only a few do so. So the patterned noise business is a matter of luck--if you are unlucky your sample of the gear may show it to a noticeable degee. If you are lucky you won't see it. I have a pretty good K10D, but my luck ran out recently when my first DA* 50-135 F2.8 arrived with a loose optical element rattling around inside like a marble. Pentax sent me a replacement right away. Joe -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
