I am enjoying the perspective of the 8mm but its reach is less than my kit lens and I find that I have to keep changing to the kit lens for a lot of pictures. The DA is great in this regard with some overlap with the kit lens but it cannot do 8-12mm.
As for the dilemma, I had to face up to this when I chose my ultra-wide path. The 8-16 was pending release then and I couldn't stop drooling over it (still can't), but some weird pragmatism swayed me to buy a 10-20 instead for the Rectilinear part, plus, for this Plan B I later picked up a ProOptic (aka Samyang) Fisheye from Adorama for the 8mm size, and some extra creative W.A touch.
Both have worked out fab for me
, got 8-20 UWA covered incl. 2 perspective~aspects, with total cost approx same as the 8-16 would have been.
And I can see your point about the overlap, that definitely was a serious consideration here too, but I had the upper range covered down to 17mm and with faster 2.8 speed there anyway. So again, it was a decision thing. YMMV.
Another choice that's gone toward helping the lens swap hassle is that I'd initially planned to upgrade to a fancier body, and again changed that strategy and bought a second camera. Reasoning being that 2 cheap but v.good cams is handier and more useful/versatile than one expensive one.
I only seek to take good pics really, not obsessed with getting hung up on bells & whistles of hardware, so that part of the "image" equation was a no-dramas choice.
Let's face it, a K-x costs less than 1/2 of many lenses these days and can take ripper pix. Which allows me to almost dedicate that to wide lens stuff, and the other body to normal/tele work. Convenience and minimal lens swaps!
Yeah OK it's extravagance but don't we all succumb to that in some way with our own kinky reasoning behind it?
Good luck with your decision on which to keep. It'll work out easy, trust your wisdom.
