Yes, the sensor of the K1 seems to have a pixel density similar to K5, I hope that the next full frame does not put more megapixels.

I find the K3II a very demanding camera with some lenses, it works very well (but very well) with my tamron 70-200, with the 90 macro, even with modern compromise lenses like the 18-200 sigma contemporary works well. But some slightly older lenses look as if they are not up to this 24 mpx sensor.
It's a pity that some modern lenses from manufacturers like Sigma and Tamron are not available ....

With the Pentax Ks2 and the sigma 120-400, I get a little more sharpness than with the K3II (Or so I think)

I would like to see an APSC camera with 10-12 megapixels but with the current image processors. Sometimes, less is more.
It's been a few years since I sold my Pentax Kr, but sometimes I miss it. These photos are all with the Tamron 70-300 300mm and f5.6

New from Spain

Hi all. I am an amateur photographer of nature, mainly wildlife, a little landscape, some macro and occasionally also some urban photography or architecture. I've also done some concert photos.
Most of my photos are taken near my place of residence, in the south of Spain, between the Sierras de Cazorla and Sierra Morena.

Currently the cameras that I have are Pentax K3II, Pentax KS2, and Nikon D7200.

As fixed lenses I have a Pentax 35 2.4, Pentax 50 1.8 and a tamron 90 macro.
Zooms used a Sigma 18-200 contemporary, Sigma 10-20 f3.5, Tamron 70-300, Sigma 120-400 non OS and Tamron 70-200.
In the Nikon system I use Tamron 150-600 G2, tokina 11-16 and Sigma 18-200 contemporary.
I use photography mainly as terapaia and to evade everyday problems and stress.
My photos I publish in 500px and Flickr, I'm also printing some paper albums.

The reason for registering in this PentaxForums is simply to make public my thanks for all the consultations I have done in recent years and for all the doubts that I have been able to clarify.
Thanks to everyone who makes this forum possible.
Greetings.
