Jed is really joking
German lenses are not necessarily better than others. I think I already wrote in other thread quoting Jed's question.
But that's depend on how you define the term "good", which is subjective, and may be different for each photographers.
MTF test by photodo.com, show that german lenses are not always superior to japanese one. In fact, the highest rated lens in their tests so far, is a Canon EF 200/1.8L, not a german lens.
But why most of people believe that german lenses are better?
Some because of mind thinking that the more expensive equipment must be better than the cheaper one, which is not always true.
Some because they know european products are well known for well engineered quality, then they assume everything is the same.
But some understand the reality:
- German lens makers always maintain their standard of quality, they don't chase the low-end market. In the other side, Japanese lens maker chasing for all market, from hi-end to low-end. As the result, their products' quality vary widely. Some are excellent, better than german lenses, but some are unacceptably poor.
I personally like japanese lenses for their sharp and crisp image (and also lower price
), but I prefer german lenses (or german optical design) for portraiture. Both the german and japanese have different philosophy in designing a lens.
The one said; It is the object's image which is in focus that is important, not the out of focus area where the photographer doesn't want.
But the other one said: Our eyes perceive the whole photo as an image, it can't be separated between the object in focus and the out of focus portion. All share the same importance.
Neither one is right or wrong, all depend on what we need and what we want to achieve.
Some japanese lenses actually use german optical design (... they 'copy' .... ), while the german never use japanese optical design.
