Hi Folks, just wondering if anyone has experience with the MDC version of this fine camera, and whether it justifies being so much more expensive than earlier models. I own the GT and GTE models, and find them both excellent. Perhaps it's just my versions, but I almost think the GT version is sharper than the GTE--but in any case, both are plenty sharp. I'm just curious how much better it could be with the MDC, and why anyone would pay so much more for one. Thanks.
