To beat an L ? That's a tough concept which has some shaky underpinnings.
One needs to understand first and foremost what an L stands for. Then, one needs to appreciate that there are many L's......just about the only thing common to all of them is a red ring.....otherwise, they are all different.
Sure like heck the L lenses are not photography magic wands, we know as much, right ?
In the end, experience and application counts for a lot. Tool quality helps but seldom decisively so.
I do understand that...but almost daily there are threads on "what lens should I buy" and invariably the L contingent (and don't get me wrong I own/use several so I'm not against them by any means) chimes in with "if you want really good photos....buy this L" I'd just like to see someone prove that non-L's can take darn fine photos when one knows what one is doing. (That often the failure of the photo isn't the glass...though, I realize CA & softness is the glass, but most of the time it's inexperience or poor technique.) Since this "contest" has got some publicity behind it (if you ever go into marketing Petkal, you'll make a fortune
) I think it will be a good example of many things....well, maybe "good" is too strong a word 

This isn't SSim and CDS
