I'd save those for Pentax lenses, too good to make holes in. Just destroy one from the opposition!

I'm not seeing a colour cast here with 1 and 2 being fine. The subject of #3 looks a tad overexposed (looks like fill in flash was used) with the whites and the skin tone merging. Photoshop or rescanning may well sort it out.
I'm a great advocate of cheap OOD film! If only I could still use and get processed several rolls of Kodachrome.

Sorry you're so uptight about its non appearance. It must be really frustrating having to wait a couple more months.

I'm not sure you need to buy any kit. I didn't. A short extension tube with some silver foil over the end with a small pin hole in it and voila.

There's a similar example How To on WikiHow here using an old lens cap.

According to Rice High Ricoh have recently filed a patent to improve AF sensitivity in the dark. Incorporating new research will naturally incur a delay but hopefully work better than what is out there now. I reckon that should be worth waiting for?

Pentax usually get the designs right but are sometimes let down by component issues such as the sensor stains and issues with the flash components failing on the K-5. Perhaps they have learnt and are making sure quality is #1. If components have to be rejected it will of course delay things. I suspect they want to make sure that no issues will affect the FF model and the new lenses designed to go with it.

Just for the record, Barrie's images were APSC (from a K-01) ; mine was on 'full frame' (36x24) 35mm transparency film. The definition on both seems to be much the same. As John's Q image was through a lens (albeit a very basic one) rather than a pinhole one would expect it to appear somewhat sharper providing it is in the focus range as John pointed out. There is no focussing required with an actual pinhole lens, but moving it it nearer or further away from the film/sensor plane changes it's field of view (or in other words, its focal length.)

As it's designed for the K-S2 it might well be a good option. They say it can be used with USB Powerbanks, My cameras use the D-Li90 which only has 3 contacts. That Freeloader one may struggle with four (but maybe not!)
What Freeloader do sell that may prove useful is their Supercharger solar panel which is quite a bit larger than most that come with powerbanks.

There are reviews of other variants of the Lemix on Amazon, some give it five stars. If you get one, let us know how you find it.

The Freeloader Pro Professional Solar Charger link comes with a 7.9v CamCaddy.

There's some monkey business going on with that one John !
