    Apart from the floating front element, it seems the MTF charts both are close and are divided into some thing better on the OLD lens and some things better on the NEW!
    I guess it’s similar really, and one really need to compare real photos to see the difference! I don’t think there going to much in it, except for being new!

    That’s crazy. It is basically the same lens, just with a floating rear group. Yet the price has doubled. Unbelievable. It’s Voigtlander and Zeiss for me all the way now, I can’t believe this nonsense from Leica.

    yawn………news lens?

    Oh guess what ? I bet you Steve Puff is going to say this lens IS WAY MUCH BETTER lens than the “old” lux ….probably even before he review it.

    What an interesting floating “element”! I cannot believe Leica introduces such a misconception in their technical data:

    Elements/groups: 9/5

    So, there are 9 elements in the lens, but there are also 5 pieces of glass that are called a “floating element”. What is an element?

    Element is in this case a section that moves on a floating basis. This improvement solves (theoritically) the focus shift problem of the old 35 lux. The old 35 lux, depending on adjustment, may have given you spot-on focuse at f/2.0, but may have shift problems at f/1.4, or vice versa. With the old lux, you had to adjust the lends to optimize whichever aperture you shoot the most, and basically “sacrificed” the other apertures. Mine was adjusted for f/1.4 since I shot it wide open all the time, but I had problems at f/2.0. The idea of using a floating element, similar to the technology behind the f/0.95 Noctilux, is that you don’t have to be forced into a tradeoff. In this sense, this lens is worth twice as much as the old lens because, well, you don’t have to own more than one of these lens 🙂 But, in all honesty, the Sum 50mm f/1.4 is a much better bargain and does not have the focus shift problem to begin with.
