so theoretically you can compare a leica m8 with a 5d mkII
ok!
I do agree to compare by price range. If the manufacturer dare to label such price, meaning there must be something to make to worth the price. eg "brand", build etc. To me, it's not right to make something look great by puting something worse beside it, without judging it's value.
And for your comparison, it's easy to make. Those like big thing go to C. Those care about size go to L. Both quality and size come with a price.
