Well assuming they remove the mirror they can build lenses where the rear element extend deep into the body therefore making any wide angle lens able to be much smaller looking as 50% or more of the lens will be inside the camera

Wouldn't that make these lenses incompatible with the Pentac DSLRs that do have a mirror?

I am not MightyMike but the answer is quite simple: yes the new lenses should not be compatible with old cameras but old lenses will be OK on all Pentax SLRs or mirrorless. To the best of my knowledge u43 does not fit on 43, Sony E lenses do not fit Minolta cameras and so on. It seems full cameras/lenses compatibility in addition to all advantages of mirrorless is like we want Santa Claus to be Adriana Lima.

Yes the new lenses wouldn't be backwards compatible but the old lenses would be forwards compatible... it makes total business sense to direct customers to buy more lenses if they want a smaller overall system, however keep the customers who already have a system happy by maintaining compatibility to the existing system. and if the existing customers want the new lenses they will need the new body to use them on.

Interesting, but I don't know about electronic viewfinders in the sun – maybe there are improvements being made in that regard?
Also, I would assume it would use up more battery with all that screen use, no?

Conversely compact and vibration free (a bit like a rangefinder) should be a good thing, no?

Also there is the wee matter of the price they want for the thing. Oh, and Ricoh's quality control – I've heard some mixed things: that they have nice designs but fall apart quickly

I doubt Ricoh has anything to do with QC yet, they've just taken the gloves off the R&D dept. and opened up the bank for Pentax to continue. slowly but surely Ricoh will get their hands in and start adjusting things. LCDs may not be that good in day-light but their is room for an EVF and without an EVF there would be a lot of wasted space.

EVF works fine on my old Pentax 750z. Not up to the OVF quality, but definitely usable in sun. It is even more usable than OVF in dark due to a nice signal amplification.

EVF is smaller and therefore it may consume less energy compared to a typical Liveview LCD screens. Therefore it helps in saving battery.

I wouldn't be expecting a bargain price on a new product form Pentax. They tend to overprice their products for the first 3-6 months before reducing the price to a competitive range. I hope, Ricoh will change that.

Pentax has one of the best built quality traditions in the market. Unfortunately Pentax is very slow on admitting design issues and even slower on issuing FW/HW upgrades on them.

Which could have been done just as easily with the adapter.

4/3 lenses do work on m4/3 cameras (and AF too) with the adapter. The AF is much slower than native lenses, but that would apply to Pentax anyway.

Same for Sony's two adapters (including SLT type adapter).

Alex, funny that your Pentax Optio 750Z has an Electronic View Finder (EVF), as none of the other ones I've seen have this, but rather have a "tunnel type" Optical View Finder (OVF), as per the review on this website on page: http://www.dpreview.com/reviews/pentax750z/page3.asp , near the bottom of the page. Those non-through-the-lens OVF's are very usable, but not EVF's. Another model number maybe? The only Pentax cameras of which I am aware that have EVF's have been the "super-zooms" as in the X70 and X90, but these EVF's really aren't very good, being low resolution and slow to update. I haven't tried them in the sun, but would imagine their limited Dynamic Range would put some limits on their use.

I had a Kodak P880 as my first digital camera. It had an EVF and LCD. I didn't really ever use the LCD because it was difficult to see in daylight. Everything was available via the EVF, so this wasn't an issue. So why not a camera without an LCD to reduce the size, if size is really that important to the market as people seem to think it is. Not to mention the savings in weight.

Articulating LCD, really, now that there is a HDMI port on cameras? Integrate an external LCD unit with remote camera control and call it a day. Integrate an articulating LCD into a battery grip for the people that can't live without it. This would be like just like external EVFs.

Think of all that free time you'll have now that you don't have to spend your day cleaning nose grease off the LCD.

Thank you
Russell

So people will have to use EVF to review images on the camera?

Sorry won't sell.

I think that new Sony EVF has a higher resolution than the best LCDs on any camera. I have to wonder what the apparent screens size is for each option is as well. You have to consider you are looking at a 3 inch screen at least twelve inches away, probably more, from your eye, versus a one inch screen at an inch or two.

Depends on the price, I would think. If leaving off an LCD provides for a smaller, lighter, and more robust camera, and drops a DSLR into the P&S price range, it might be pretty interesting. It might be pretty interesting for the manufacturer as a way to sell lenses to a whole new market as well.

Thank you
Russell

Gordon,

It's more than two years since I touched it last time, so my senile brain assumed it's the EVF simply because of its quality inferior OVF of K10D or K5.

I guess the rest of my theories about Pentax EVF quality may be safely ignored. The only correct point was that the viewfinder of my 750z saved battery compared to 750's LCD. I hope this is still indisputable fact :).

Many thanks for the correction.

I'm already carrying a high quality OLED, in my phone. Cable, Android/iOS app, done. Heck, make it wireless.

So is it reasonable to guess that K-mount lenses will have slower AF on an EVIL K-r successor than they do on a natively-mounting DSLR?

I think so. There is major difference betwee lenses designed for PDAF vs CDAF

(1) PD-AF lenses are designed to move quickly a certain distance.

(2) The lenses optimized for CDAF can do very small steps in quick succession. The built-in motor in these lenses is also able to do quick small steps.
