What is Pentax's obsession with slow lenses. Seriously. They really, really, really like slow lenses a lot.
I don't like to dis the new products, especially before they are released, but I just don't see the point of this lens. Or, to be more specific, I don't see why on earth they would release this physically larger, slower lens prior to releasing something with potential for better performance on the wide end, like a fast wide lens or a faster wide zoom.
It's like the people who design these products have never been in a low-light situation with a camera and wanted to take a photograph.
IMO, its exactly that they do consider what a photographer usually does that the Pentax lenses make sense.
UWA, is about taking in large expanse of a view.
Usually its not about shallow DOF, nor shooting poor IQ images hand held.
Its about using low ISO and steady shooting (be it on a tripod or bracing enough) for most cases where a UWA is concerned.
Of course that does not mean ppl don't shoot UWA hand held in low light.
Just that the thinking behind the lens is a set of compromises and thats how it was chosen to be.
But this thing at f3.7-f4 has plenty DOF and not too slow f4, so ISO can be at a push of ISO800 with a brace/support (not that hard since the camera is so small), maybe 1/30; 1/15; 1s at a push.
I've done the same with the toy fisheye which is 1 stop slower at f5.6.
Q7; ISO3200; 1/60; f5.6 Toy Fisheye
If I was willing to trade shutter speed to 1/30; f4, ISO would be a better quality ISO800.
My few cents.
