seriously though, I have been a regular member on a number of forums in my time, and this is probably the friendliest of the lot. Certain characters have managed to try our collective patience over the years but generally you have to try pretty hard to annoy us.

An f/1.0 50mm just has to have an entrance pupil 50mm across, the size of the rear element only scales relative to this if you are just taking the same design and scaling up. My 300mm F2.8 has an entrance pupil diameter in excess of 100mm.
I don't know, I'm not a lens designer, but it seems to me that enough R&D ought to be able to sort out the light path to make a 50mm f/1.0 possible.

This feature, while it doesn't seem likely to be the reason I WANT to buy a K-7, may well be the reason I am ALLOWED to buy a K-7/8/9 in a few years time when babys start comming along.....

I've read plenty of contradictory views regarding the image quality. Some say the Sigma's bokeh is horribly distracting, others tend to think it has the edge on the Tamron. All three seem to have their fans - making it difficult to choose!

yes, cartwheeling towards your opponent and getting smacked in the head, I can see how that would be an effective fighting style....
