Maybe I could get a Zeiss 21 (though large...fine performer) and use that as my 35mm equiv???
Douglas_of_Sweden - thanks for reminding me about the weatherproofing. I assumed that all the newer Pentax's were but I guess not. So it needs to be a DA* or WR designation to tell me it is suitable for those conditions? I'm not up to speed on the Pentax terminology yet
In regards to flash, I do like the Nikon system but seldom use it. I'm assuming Pentax has a wireless system similar to Nikon??? If not, I will look, but is it compatible with a radiopoppers setup?
Maybe selling off one or two Nikon items and trying the K5 with a lens or two will be the best way to test it. I don't have any Pentax dealers around in my area so it is hard to get a hands on with this system.
Thanks for the comments all....keep them coming
By the way, I have found the DA Ltd/FA Ltd/DA 15 threads and they are amazing
Fast and wide and in production does not give you much alternatives. The Sigma 20/1.8 is a good lens. But if you want away from big and heavy, it may not be to your taste. Also, it does not have the build quality of the Pentax lenses. I'm currently trying the DA21/3.2 for tasks that I've previously used the Sigma 20/1.8 for and with the high iso performance of the K-5 I can't say that I miss the speed. You are not likely to seek razor thin DOF at such a wide angle anyway, are you? The DA14/2.8 could be a compromise. It has it's own thread somewhere on the forum.
Yes, only DA* or WR lenses are weatherproof. I suspect it would be impossible to build the compact DA ltds weatherproof without loosing that special feeling they offer. On the other hand, I've never had any problem with water getting into them even in moderate rain. After all, they don't expose much surface to the weather since they are so small
Pentax has a wireless flashfunction. But overall, Nikon is supposed to have the best flash system of all DSLR systems. But as you indicate you don't use flash that much the difference may not matter too much.
As you probably notice, the fanboyism isn't that heavy on this forum...a majority of the responses to your questions appears to try to talk you out of changing, not because they don't like Pentax, but because of respect to the Nikon gear. Somehow they miss that you appear to know already why you want to change, but that you want advice on the Pentax options.
Also, notice that most of those that keep saying that you wont get as good autofocus with the Pentax system does not have the K-5 on their list. It appears that Pentax have finally bothered to invest enough to catch up with a large part of the difference to Canon/Nikon. I'm not saying that they yet have an autofocus that match the pro-models of Canikon... they don't have (yet) a pro-model, and you don't pay that price for a K-5 either, but the difference between the K-5 autofocus and that of comparable Canon/Nikon models appears to be small.
Good luck!
