Don't like number 4, sorry
But I love number 1 !!
I don't like the fisheye effect in pretty much everything I've seen. It just doesn't do anything for me and detracts from the quality of the image. (IMHO)

If C&C is asked for then it should be accepted..good and bad.
As long as it is constructive criticism we shouldn't be afraid to hear it. The quid pro quo is that when giving C&C it should always be respectful and constructive.
If we all agree to that, then there is no need for another way of doing things.
IMHO..of course

This still is a reasonably friendly place and as Darkmunk says, friends can argue..I'd rather use the term "Debate". Here's hoping that after the debate we can shake hands, agree to differ and all go home happier for the sport.

It emphasises the symmetry between the grille and the lens of the light.

Sorry
To explain decentering, when lenses are made up of many elements these elements need to be in the correct locations and their centres lined up perfectly. Decentering can be measured and shows how far out of line some of the elements are. The higher the figure, the worse the lens.
I'm now going to take that list and add a second % figure - this is the 40 lpm MTF figure and indicates the detailed resolution performance two stops down.
Sorry if this should be common knowledge
