I've noticed that magenta cast too using certain old M series lenses with various bodies when an otherwise identical photo taken with another lens did not show that cast. No idea what causes it but it wasn't the camera. I believe I note that you too use several M series lenses and they could well be the cause of your magenta cast.

I still dislike the colour rendering of the K-5's, with their tendency to a magenta cast. That must be a peculiarity of the Sony sensor since the K-3 is the same.

Looking at some actual facts from DXOmark we get the following:-

In order of K3 K5iis K5 K30
Landscape Dynamic Range(Evs) 13.4 14.1 14.1 13.0

Sports (Low LightISO) 1216 1208 1162 1129

Portrait colour depth was virtually identical for all models.
Now I don't know how good, how accurate or how meaningful these results are. But to me they look like in the real world you would need some very stressed conditions to see a difference. You would have to decide for yourselves whether the 24mp and other features are worth it for virtually the same spec in the above areas.
It will be easy for me to move up from the K30 for my predominantly wildlife shooting.
Apart from the small improvements in all of the above I will get:-
1. Much quieter shutter
2. Faster burst
3. More cropping ability
4. Greater resolution with no AA filter
5. Faster more accurate AF (Most users say this)
6. Better tracking of moving subjects (Most users say this)
7. IR remote on the back

plus other useful features not on the K30, so easy for me

The K-5 and the K-5ii have the same resolving capabilities as they both have the AA filter.
