Ohtake-san:
Forever is too much time. A lens is like love: must be eternal while it lasts.

Another nail in DSLR's coffin. Don't be so cruel, Sony!

Frank_BR: This is a camera for those who want to shoot sports and do sports, all at the same time.

Or from another point of view, it is a camera to spend money on and make money from.

I don't have the figures, but I believe that APS-C cameras like the Canon 7D, are more popular than the 1D, especially for birding.

Olympus and Leica cameras are yin. Nikon, Canon and Panasonic are yang. Some Sony models are yin, others are yang. Pentax? (thinking...) ... sincerely, I don't know.

The volume of Sony cameras sold in 2015 may have decreased 5%, but the number of posts on Sony cameras has increased more than 100%...

Ridiculous! Nikon announced price increases the day before the Japanese government announced negative interest rate!

Nikon is heading to be the Ikon of twenty-first century.

Frank_BR: Instead of wasting time with products of dubious utility like this ceramic filter, an optical company as Sigma should think about launching more useful products. For example, a complete collection of high-quality achromatic close-up lens like the Leica Elpros, but at low cost. I believe that such type of product with a fair price would have a huge market, which begins with compact cameras, goes through 1", m43, APS-C, FF, MF and ends at professional video.

Yes, I know there are already manufacturers of achromatic close-up lenses on the market, such as Canon and Marumi, However, their close-up lenses are more expensive than they should. For achromatic close-up lenses to become really popular, it is crucial they are cheap, what is only possible with production scale.

I found the sample #4 with only half cat as much intriguing. Can we conclude that for the full-length photo of a cat one needs a full-frame camera? Or perhaps a photo stitching with the PEN-F?

Paper capacitors have become obsolete since the 1960s. They were largely replaced by metallized polyester and high-capacity ceramic capacitors.

Well, we went off topic so far that I want to say it was a pleasure talking with you, and want to say sayonara through a music played by "Os Incríveis" (The Incredibles). The lyrics have parts in Japanese and Portuguese. The song was record just after the tour of the band in Japan in the late 1960s. Os Incríveis was inspired by The Shadows and was the best Brazilian band of the 1960s.

I never lived in Japan and cannot speak Japanese, but I have been living/working for years with many Japanese or Japanese-descent people. I think I know reasonably well the values ​​and ethics of the Japanese. I admire the Japanese people, but my trust in Japanese corporations began to erode when I had a bad experience with Canon, who never acknowledged that their video cameras, particularly the L1 and L2, which were Canon's Hi8 camcorder flagships in the first half of the 1990s, were destroying themselves due to leakage of electrolytic capacitors.

About R&D, design, manufacturing, oh yes, I had my fair share of them, but I wouldn't call myself an "expert" in any of them, let alone in photography. I have interest in technology in general, and in photography, in particular . I'm an electronic engineer, and I have a background in digital signal processing and communications. Certainly I am not talking nonsense when I say that digital photography has something to do with my profession.

It is not a matter of technology but of the production and distribution scale. It is not a task for an independent entrepreneur or a small business. Large US corporations are extremely conservative and bureaucratic. Japanese corporations are an order of magnitude worse. Believe me, I've had direct experience with those people. If you have a good idea, this is not enough for them to pay attention to you. Remember, even Steve Jobs was expelled once from Apple. And Tesla, a true genius of electrical engineering, was humiliated and fired by Thomas Alva Edison.

"There you are, a perfect opportunity for you to start a business. When can the photography community expect your product at the same or better design / quality at 70% or cheaper than the current market price?"
---------------------------------------------------------------------------
I really love that kind of reasoning... I think I made it clear that it was a task for a big lens manufacturer with a global distribution system, but I'm afraid you did not notice.

Let's talk seriously, Samyang produces a 500mm F8 mirror lens with 7 optical elements. That lens which contains a precision focusing mechanics plus a machined mount is sold for only $99 at B&H. Why Sigma could not produce on a large scale an achromatic close-up lens with no moving part for 1/5 the price?

Last but not least, any manufacturer that accepts the challenge would have to adequately promote its products. It is also necessary that manufacturers change their mentality. Since Kilfitt discovered the way with its Makro-Kilar in 1955, the overpriced dedicated macro lenses have become a way for manufacturers to milk the lens market. It is time to change the idea that quality macro-photography is only possible with dedicated macro lens. Affordable achromatic close-up lenses are the way.

The article forgot to say that people do not buy cameras based only on technical specifications. The cost can be more important than the technical aspects. For example, a typical Leica enthusiast cannot afford to buy a camera that costs less than $4,000, no matter how good it is.

In certain parts of the world a photographer can have 10 spouses, but none will question him about how many cameras he owns. :)

Mike Maier: Please check context of your last sentence, "and provides an exceptionally clear view through the Leica M viewfinder.".
Yes, Leica M viewfinder is very bright, but that has nothing to do with quality of the lens, lens shade of 28 mm lens usually just blocks part of the viewfinder.
V/r
Mike

I was just playing with the ambiguity of the word "clear" that can be interpreted as "bright" as well as "free from obstruction," among other meanings.
