You might be able to track down a Kx at a reasonable price... and it's a very similar camera to the Kr under the skin.

Well if you want to dump the Chinon 50mm, please dump it in my direction!

Houses are OK, but the same view everyday gets a bit boring... and you don't get kingfishers flying past the window!

I don't miss rolling Calor gas bottles for 1/4 mile along the towpath, or getting stuck in ice miles from the nearest pump-out though!

A number of people will value the fact it has an extremely useful range on both 135 format film and APSC digital, and is full-frame future proof. This niche market probably exceeds supply. The 18-55mm on the other hand is oversupplied, and can even be bought new for under £50

I think it's pretty cool... you can really appreciate what a complex piece of kit that camera really is.

Is it art? Dunno. Don't care!

The MTF graphs look very similar at f4. The problem is, the Tamron 17-50mm has them both beat!

If the MF offers something better than a FF DSLR, doesn't it follow that a FF DLSR would also offer something better than an APSC DSLR? Do I detect a hint of 'sour grapes' John?

I know but we are deliberately excluding lenses, after all you can use a Pentax lens on a non-Pentax camera...

I was meaning the in camera settings: Vibrant. Portrait. Muted. I suspect that if you play with these settings you can replicate other brands, especially ones that share a sensor. However I think John's probably correct that there's some pre-processing applied even to RAW shots, and AWB / preset WB values can obviously vary (my K7 'daylight' setting is rather yellow for example).

Presumably that just depends on the in-camera processing option you select, rather than the brand? Shooting RAW should level the playing field, at which point the sensor is the deciding factor.

A picture of the lens (or flash etc) actually on a Pentax DSLR could help reassure bidders who may be unsure whether it will work on their Pentax... I also include the names of popular Pentax DSLRs in the listing in the hope of attracting newbies who search for 'lens for Pentax KR' etc!
