I agree with that ,in my experience I use aperture f/8 0r f/10 when using this lens at 16mm and it is very sharp.I compared it with my DA 12-24 mm at 16mm ,it does the good job.

Probably not. I was disappointed at first, this is my second copy and it is an improvement on the first. Over time and usage I have come appreciate it's colour, contrast and sharpness (all be it at a more limited aperture range than I would like). I was hoping it would be the Oly ED 12-60 SWD of the Pentax range but it isn't, never-the-less I still think it is a good if not great lens.

Will the 16-50 be a worthwhile upgrade from a 16-45?
How do the 16-50 and 16-45 compare in terms of image quality? I know the 16-50 is better built, the 16-45 doesn't have the highest build quality I have seen.

Sure Aiki,
this is a gas chromatograph/mass spectrometer combination. I don't work with this but in our department (Marine Chemistry) it is used to measure pollutants in sediment and water samples.

Oh no, now the secret is outDon't be taken in Aiki, it is Ralf's secret lair where he is planning world domination.
It might not be a big secret, though. Isn't it what all Germans plan?

I think that Ralf set up a 'sleeper cell' in Southampton some years ago
