Why are Pentax lenses much more expensive than in previous years? And many good quality heads have been discontinued.

The problems that most photographers with oriental style encounter when choosing Pentax lenses are: either the focal length is too narrow, or the maximum aperture is too small or unstable, or the price is too high, even the focal length of the classic fixed focus that Germans think is so awkward. We just like data like 35mm, 85mm, F 1.2, 1.4, 1.8, 2.8, 70-200.

In fact, the root cause of this situation is that in the post-SLR era, we are deeply impressed by Japanese style. Company C is really good at being the second in the market, and they have lowered the invisible cost. Let me give you an example. For example, the shutter of Pentax's entry machine can be used 10w times. You can check how many times 450D-600D can be used. If it is not used at high speed, it may be impossible to control the lights and must be replaced. Elsewhere, I won't say much about the lens, including the dispersion control of the lens, as well as those problems of power supply and focusing speed. Of course, the Japanese did conquer many European and American journalists. So I can only say that each has his own strengths.

Do you know the story of Germans building parks in South Africa? You can search. We orientals think they are stubborn, they are not as flexible as we are. Do you think they still stop producing high-quality lenses and the lens group is not perfect? In fact, it is not surprising that similar problems happen to them. They find information that others can't see and go to work silently, but if you read the story of South Africa Park, you may change your mind. You can look at Hasselblad's lens, which is also the product of the Germanic nation. Are those data hard to accept at the moment? The price is certainly bloodier.

I can only answer your question from this angle. It seems that many photographic equipment in Europe have been transformed by old photographers, such as Li. You can look at their works.
