questions on the K30 as a system:
What lenses are (or are not) weather sealed ?
It would seem you could look this up? However, the 18-55 WR kit lens (that does not come as part of the kit with the 18-55 kit lens option in the US) is available as well as the 18-135 WR which can be included as a kit. Other than kit lenses, there is the 100 mm. macro WR and most (all?) of the DA* lenses, including the 16-50 f/2.8, the 50-135 f/2.8, the 60-250 f/4, the 200 f/2.8, and the 300 f/4. The rest of the lens that can be fit to a Pentax mount are not Weather Resistant (WR).
Are there two lenses which will cover FF 24mm to 400mm reasonably fast ie start at least sub f3
Two zoom lenses? Weather Resistant (WR)? I don't think any company builds a telephoto zoom lens that goes to a real 400 mm. and is f/2.8 at the telephoto end, and if they did it would be extremely expensive and heavy. If you accept a 400 mm. equivlalent zoom range for APS-C sensors such as the K-30 (about 270 mm., then Sigma make several different 120-300 f/2.8 zoom lenses but they aren't WR, weigh about 2.6 kg., and cost well over $2000. If you were to accept f/4 at the long end, you could use the 16-50 DA* f/2.8 and the 60-250 DA* f/4 or (almost overlapping) with not quite the equivalent telephoto range or for quite a bit less could find third party lenses such as the Tamron 17-50 f/2.8 (equivalent to 25.5-75, not as wide as 24 mm.) and a third party 100-300 f/4 lens, but you still wouldn't be covered between 50-100 mm. and would need a third lens.
Does Pentax K-30 have in built wireless flash detonation and decent autobracketing ?
Yes, it does.
Is battery life an issue relative to other DSLRs?
Yes, the capacity of the Lithium Ion battery that comes with the K-30 is considerably less than other DSLR's and may be less than even mirror-less cameras such as the Olympus OM-D EM-5, meaning that you may want to use rechargeable Low Discharge NiMH batteries such as Sanyo Eneloops or keep a spare battery on hand.
Any other foibles anticipated?
The reviews on this website or at www.imaging-resource.com cover pretty much all the "foibles" between them.
killer price with the kit lens in Europe, but I am wieghing this as a system change, against an OMD EM5, or an E 5 with used 12-60 f2.8 and 50-200 f2.8 (24-400 range) as a system.
This is one of the advantages of the smaller four thirds sensors: good quality longer range zoom lenses can have wider open apertures and still be smaller and lighter, although that is a trade-off against the superior high ISO capability of the full Sony APS-C sensor cameras such as the K-30. You'll have to decide for yourself which is most important to you.
