What does "the smell of virtue and poison" often mentioned in photography mean?

There are not many lens brands in Germany, but the optical quality is excellent, which is related to the German habit of attaching importance to quality.

At present, Carl Zeiss, Leica and Schneider are the main brands of camera lens production. Lulai also produced excellent quality lenses, but later withdrew from this field due to business problems. RODENSTOCK mainly designs large-field lenses.

German products have always been famous for their preciseness and exquisite workmanship, and even the faultfinders can only keep silent about German cameras. I read a lens evaluation post, and compared the clarity and imaging stereoscopic impression of Canon's top lens and Lycra lens under the same conditions, Lycra lens far exceeds Canon lens.

In order to pursue impeccable quality, some German lenses are handmade or semi-handmade, such as Lycra lenses. It is also the case that German lens production is not high and the price is expensive.

When it comes to lenses, I have to mention Carl Zeiss brand, which has strong technical research and development capabilities and has always been the leader of new technologies, and is the leader of other brands from lens coating to internal structure design.

As long as you cooperate with Carl Zeiss, you can gain a foothold in the camera market. Hasselblad and Lu Lai used Zeiss lens to sit in the top two in the Jianghu. If Sony, an optical amateur, doesn't use Carl Zeiss lenses, few people will buy them.

After using the lens made in Germany, I will have a new understanding of photography. It turns out that light and shadow art is so charming.
