I feel it is impossible to create something excellent if you shoot only the things you can see.
Even hardships will turn into wonderful memories when you look back later.
seemed to regard it as unavoidable.
With digital cameras, however, once dust attaches to an optical filter or image sensor, it is captured in all frames.
The biggest advantage of having an image stabilizer built into the camera body is that camera shake can be compensated for with any lens, from fisheye to super-telephoto.
And another advantage of this design is that it facilitates implementation of compact, high-performance lenses because it does not impose restrictions on the lens design.
the advantage of the linear system lies in its high accuracy
the lens is useless if it stops working when it is used in a harsh environment
Since lenses are in service for five, ten or even twenty years, their design needs to deliver high performance today, while taking into account the future improvements in camera performance
