Just speculations on mirrorless and Pentax

This is only my opinion, no one has to agree with it, but trust me I am an engineer. ;)

I think the future is mirrorless, it just has better properties then the DSLRs, we just can't use them all now with current tech.
The mirrorless has at least these advantages:
  • No need for separate AF and AE sensors, the main sensor can do all of this.

  • No need for AF adjustment, the main sensor always can check it with contrast detection.

  • It's lighter, the prism is big and heavy.

  • Shorter flange distances are possible, so more tech can be added in place of the mirror or thinner body can be created.

  • Shutter lag can be totally eliminated. If the (future) sensor captures continuously, then the camera can save the image taken when you pushed the button or even before you pushed the shutter button.

  • Any custom overlay can be added to the viewfinder image. Focus peaking, histogram, under/overexposure warnings...

  • Exposeur can be simulated. (I like it when I half press the shutter button)

  • Low light manual focus is easier with "correct exposure" viewfinder image


Thanks to the VR madness small high quality, low latency, HDR monitors are advancing very quickly, so the viewfinders gets better while the research costs goes to other segments, because these are mandatory for VR headsets. I think EVFs will catch up in the next few years.

While I'am a Pentax shooter and I really like my KP and the OVF, I think the future is the mirrorless with EVF, we are only waiting for faster readout speeds and lower power consumption. (Lower consumption is also mandatory for the sensor cooling, we need a continuously running FF sensor for these!)

So where is the mirrorless future proof Pentax camera (or at least development)? I think there are some technologies they are trying: The K-70 has on sensor PDAF, so we seen the first version and I think the LiveView is good in the KP.
Altough Pentax does not have their own sensor development like Canon and Nikon has according to the fresh news, they really depending on Sony and we don't know how many alternatives are there. Sony may be prohibiting for Pentax to make mirorrless in change for the access to the relative new sensors. I trust in the engineers at Ricoh, they have a much more information about the market and the opportunities, so I hope they choose the right tactics.
Maybe we will see some tech in the GRIII which confirmed to be coming.

Of course there is another factor: the K mount which keeps many of us at Pentax. A mirrorless needs a new mount, with new technology. While there is the option to make "designed for mirrorless" KAF4 lenses, I think we would loose too much by keeping the mount. Although getting to a new mount would split the not so fast lens development team too, so I think they currently does not have the resources for a mirrorless system.

I have the silver KP. It's painted over black material, I have some abraison on it. I think it's still looks better than the black, but I agree with E-man, It's easier to keep the black one looking nice.

I think there were some discounts for long time pros which ended now, but new subscribers only has the one year $49.99 option. I've payed it two times now and I don't see any change in my future pricing.

Straightening would help, but you would need a shift lens on film for it... I would choose an emulsion with more contrast for buildings or use some filter for the scene.
Anyway it's a great composition I like the image!

I think the you should keep the foreground, it adds some interest. The contrast and exposure is fine too. I would darken the forground just a little bit with one-one gradient filter on each side. I would turn them in approximetly 30 dgree in this direction: /
