It will be interesting to see if Canon fans will buy this camera. Canon users have been saying for years that 21-22 mpx full frame cameras is all they need. That plus the limited ISO capabilities compared to todays 5DMlll will make it kind of a controversy to buy one of those ;) Not to mention the expected higher price. And not to mention that there are rumored at least 2 medium format cameras with around 50 mpx on much bigger sensors that will deliver much better IQ for a price that is rumored to be not far from the price of this new Canon line.

I don't put much stock in these rumors or leaks or what-have-you. Until Canon issues a statement it is all just guess work, no matter how much some people want it all to be true. I never read the full list of supposed specs till just a few minutes ago and I must admit that what caught my eye was the claimed 1.3x and 1.6x crop sensor modes. I am curious as to just what this means. I don't believe it refers simply to the ability to use EF-S lenses the way it is stated. It will be quite interesting to see if any of this is accurate.

Huh?

I'm sorry, but I seem to recall that Mamiya has been producing a Medium Format offering for some time now, ie. the 645D???

---No, that is Pentax.---

Or are you talking about a different Mamiya than the one already in place?

---No---

In fact, I think the Mamiya medium format digital camera was one of the first produced, in concert with their only camera offerings for decades being in Medium Format film and digital. Mamiya's last other camera format was their great 35mm film camera's which ceased production in the 70's for financial reasons, particularly lack of sales. They remained however strong in Medium Format and have a great reputation for their Mamiya Sekor lenses. Competitive with Hasselblad.

---Yes, except you are mixing Mamiya with Pentax in some parts---

I make that distinction because Mamiya would already have a lead in Medium Format digital, because their lenses are already, and have been for years, capable of the resolution for a MF sensor. Not like the problem that may exist with using Full Frame lenses now on the market for a sensor doubling the resolution of recent/current full frame inventory from most manufacturers.

---I am already collecting Mamiya lenses in case it will be possible to use them on the new medium format digital camera---

Again, most people are going to be outshooting their glass with a 50 Mp sensor.

---Right, but applies mainly to 24x36 mm format. Medium format and older lenses fit much better as long as the sensors are only around 50 megapixel. Megapixel density on the medium format sensor in the Pentax 645z is only similar to 24 megapixels in full frame cameras. Then we also have to keep in mind that the medium format sensor used in Pentax 645z is a crop sensor, not full size medium format sensor.---

Some years ago, I bought a Chevy with a relatively high performance engine in it.... a 350/300 HP engine. I took that engine out and built a new 400 cubic inch engine generating about 475 HP at the rear wheels (dyno'd).

It was a very fast car.. Scary Fast! But only for 1/4 mile trips. The car was totally useless for any other purpose in real life. Lasted me until I could build another faster one. Insane.. of course!!!

So, the 50Mp Sensor, without the tools to make it an everyday tool. Great glass. :thumbup:
