Dont tell my dog he has his own castle

No 3 gets my vote.....possibly overprocessed but that is why it stands out. Nice

2 and 4 for me.

I know no more idea about what Pentax has up their sleeve than you do. But look at these quotes......

"When you take a picture with a single lens reflex (SLR) camera, the light passes through the lens, and in turn the optical viewfinder. You view the image directly with your eyes, and feel it with your heart."

"The intuitive shooting process made possible by the SLR mechanism — the lens, mirror and prism viewfinder — can best be described as a pure joy."

"With an SLR, photography is more like painting a picture than operating a mechanical device"

"Light passing through the lens is reflected by the mirror to the pentaprism, which in turn directs it to the viewfinder’s eyepiece"

"PENTAX showed its commitment to the development of the optical viewfinder by incorporating a glass pentaprism, which allows the light captured by lens to be viewed directly with the naked eye."

"the optical viewfinder captures subtle nuances of the subject’s lighting conditions, colors and shades."

These are taken from the latest statement of Pentax core values published within the last month. These suggest your idea is not likely.

Further, although I am no camera design engineer, I would think it highly unlikely that a camera with the design philosophy of a hybrid viewfinder could be suddenly switched to being a simple old SLR instead.

I love that image Chris. Beautiful

Agree. I used my K10D for 8 years and it was still going strong. I have been using a K1 since 2016 and still havn't used all the features. No requirement for me to get a new camera anytime soon

Good glass is good glass and will stand the test of time. There a number of us on this forum who regularly shoot with older film-era lenses.

If you intend to print your pictures very large there may come a point where the resolving power of an old lens will not match a modern one. But it will depend.... a great old lens will probably beat an average modern one so it is difficult to generalise. The latest 24" x 16" print hanging on my wall was shot a couple of months ago with a Pentax-M 85mm f2.0

One area where there is a difference is flare control. Older lenses do not have the improved coatings that modern lenses today use. So always use a hood and in tricky lighting scenes be extra vigilant you dont get the sun in the picture. Digital sensors are also more susceptible to stray scattered light than a film camera is, so another reason to use a hood.

The M 50mm 1.7 is a classic. I still use the one I bought 40 years ago.

Quite scary

I like the first one....very delicate

That number 7 is interesting. Looks like a piece of graffiti art by Miro !
