对于Vario Elmar设计师的采访，第一个问题，是设计的五项原则
Q: In the case of the Leica X Vario’s lens, what five disciplines did you look at?A: Sure, here are the five things we really strived to achieve with this lens:
1、Imaging quality equal to that of the best Leica M-Lenses
2、Constant imaging quality from the minimum focusing distance to infinity
3、The best conditions for fast autofocus
4、A compact construction
5、The familiar rugged and resilient construction of a Leica M-Lens.

第二个问题回答了对标镜头Q: Although all five criteria are important, is there one of these that really stands out as a must-have feature for this lens?
A: Naturally, image quality was the most important feature of its design. The Apo-Summicron-M 50 mm f/2 ASPH., the newest and one of the sharpest lenses of the M-System, set the standard to be met. The declared objective in the case of the Vario-Elmar was to guarantee a comparable contrast transmission from corner-to-corner of the image frame. It must be said that the Leica X Vario is equipped with an APS-C sensor. Therefore, achieving imaging performance comparable to a full-frame system increases the technical demands by 50%.

第三个问题，回答了为了质量舍弃的光圈，当然，能做到近3倍变焦保证锐度和成像已很不容易。
Q: What were some of the challenges faced with designing the lens for the Leica X Vario?
A: The spec sheet for the Vario-Elmar was a sporting challenge – contrast transmission that has no need to hide behind that of the best M-Lenses. Even though this performance had to be achieved with a much smaller APS-C format sensor in a compact camera, and this throughout the entire almost 3× zoom range and from the closest focusing distance to infinity.
We could only satisfy these demands by lowering the bar somewhere else. This explains why the maximum aperture of the Vario-Elmar is relatively slow, between f/3.5 and f/6.4.

总而言之，X Vario产品初心是小M，虽然小底，但不妥协画质。为了画质和整体紧凑，牺牲了光圈确保锐度。

理论上这个产品定位非常精准，高素质变焦随身机。
