I've just got a new SMC Pentax-DA 12-24mm lens, so I thought I'd like to share a picture:
It's Brothers Water in the Lake District.

Nice photo (leads the eye through very nicely), and I've not heard of that lake before. Shows you how good my geography is, considering I lived in Cumbria for ages. Is it true that after a certain focal length, lens begin to give spherical distortion a bit? Can't get my facts right in my head on that one.
Ceci n'est pas une signature.

The wider a lens is, the more difficult it is to design it so that straight lines remain straight lines. At the extreme, the fish-eye lens doesn't bother to try and you end up with some wild and wacky results.
This 12-24mm is "rectilinear" so straight lines should remain so, but at the extreme wide end it does start to bend a little.
The other thing you might be thinking of is "spherical abberation" which causes colour fringing in telephoto lenses. I am not going to attempt to explain that one!

I like the effect
I like the effect of the clarity of light as it hits the rippling water and the different textures in the composition. The sharpness and colour quality enhance the experience.

Thank you for that, but wouldn't Granny wonder why you sent her a picture of the Lake District from Madeira?
You need to be careful of Grannies - I sent mine a nice little tale of Haggis Hunting in the Highlands and she was quite cross. She wanted to know what the weather was like.
So my favourite postcard phrase now is "The sky is bluer than even this picture postcard can depict". Sometimes this, too, does not go down well.
