I totally understand the logic of swapping the 18-55 for the 16-45 but I live in NW England where WR gets a lot of use. Locally we have thirty words for rain. It is something I will keep in mind though as it would be an improvement in quality.
I have also been looking at the Samyang 8mm because I fancy something fishy. The Samyang is 3/4 of the way to the price of the Pentax but doesn’t have the flexibility. I am pretty much sold on the 10-17, unless a sigma 10-20 or a Tamron fall into my lap.
Thanks again for all your input. This has been an interesting thread :0)
I have both the DA16-45 and the DA18-55WR - living in Manchester I appreciate your point about having WR, but your alternatives aren't WR either.
There have been many threads about the DA10-17 vs the Samyang 8mm. I also have both. The Samyang is a better fisheye, but of course it does not have the flexibility of zoom and AF. It does however have a better projection and a wider field of view. For example, if you want to do 360 degree panoramas then with the Samyang you only need 6 shots (4 directions + zenith and nadir). The Pentax needs 8 (6+2).
There have also been many threads on defishing fish-eyes. It is not hard, but you lose image quality in the stretched image corners. And framing gets a bit more tricky, since you have to visualise what your shot will look like when defished.
