Let me preface this thread with: So Thanksgiving has just past, enjoyable weekend and it's a lazy Sunday afternoon...
So the Pentax 645Z has a 51.4MP CMOS Sensor - 43.8 x 32.8 mm, so why is it not called a P634Z. I'm sure the camera merits a lot in the Digital Medium Format world, and I'm sure calling it a 645 bothers absolutely no one, 'including myself!'
Yup, I know crop sensors and the 645D before the Z have smaller sensors than the IQ180/280 (53.7 x 40.4 mm) for example, but PhaseOne have not stuck the well know 645 on their camera backs, just simply the IQ series.
However, why not call it for what it is. Hence in 135 world, why not call all APS-C full frame then!
So why am I bringing it up? Well, I find it rather amusing and only really paid attention to it more recently since I also find it a rather desirable camera to eventually have, as soon as the leaf shutters come!
In the meantime, I'm waiting for my Fujifilm GA 645 to arrive!
