My other half is likely to pick up a K5 shortly for a business trip she'll be on for 12 mths. It'll be a fairly harsh environment (both temperature extremes, and abrasives etc...), so she is pretty sold on the K5's WR properties.
Plan most likely is to grab a twin-lens pack with the 18-55/50-200 WR's... she wont be in a position to play with primes so its an adequate compromise...
However - since having picked up my 18-50 Sigma 2.8-4.5 , I've been wondering.. would this be a better option over the 18-55?
I realize its not WR, however it may as well be given its all internal zoom/focus and solid build.. the electronics might not like swimming too much I guess..however water shouldn't be an issue compared to the other environmental issues mentioned... But the Sigma seems a lot sharper and more flexible than my 18-55 kit-lens I have (from the K10D bundles)...
What do people think ? Grab the 18-50 sigma, or stick with the WR benefits of the 18-55 but lower IQ ? Its more a harsh environment than a wet one.. but it might be an issue...
