Pretty much what the title says...
For me, a couple of desired features would be:
---Articulating Screen
I find myself using the live view now and then on my K5ii, so this would be nice to have. I had the opportunity to use a Sony A6000 before upgrading to K5ii, and I found this to be a useful feature.
--Smaller size, lighter
I think my camera is the only "gadget" where it has actually gotten heavier, and bulkier over the years. My previous dSLR was the *istDL2, which in size/weight comparison to the K5ii, looks like a mirrorless now
I understand the newer bodies are all magnesium, the sensor shifts, ISO is better, etc., but I would like to see these packaged in a lighter body.
--Better Video
I know most people do not care about video on their DLSR, but I do
I think 4K will not happen any time soon for Pentax, but I would at least like autofocus. Then again, with an old AF lens, you are likely to be hearing the motor of the lens in the video... But I don't know... It would be nice to have more choices re. video shooting, such as compression options.
--More megapixels, more body colours?
...because you know, more is better... Sorry, I could not resist an ill-fated humour attempt
--I would also like builtin GPS and Wifi, but I know these are not happening, since Ricoh has gone down the route of "modularising" these with out of the camera accessories.
What are the features/improvements you would like to see in a high end upcoming model?
Cheerio,
Mike
