This is the official Sony announcement: Sony Global - News Releases - Sony Discloses Basic Specifications of the "E-mount" for Interchangeable Single Lens Cameras without Fee.

Specs are not publicly available for download. It seems to me as if only companies can apply for the documentation but I might be wrong.

As we all know Pentax DSLR market share is very low. It's also not a secret that Pentax lacks modern full frame lenses. The last Sigma Art(50 and 20mm f/1.4) and Tamron (35, 45 and 85mm f/1.8) lenses do not come in K-mount. Most of the Pentax lenses are old or only cover crop but not full frame sensor. Yes, there is a wide variety of old film-era lenses but they are not optimized for digital cameras, most of them are manually focused and this will prevent K1 from showing its full potential.

On the other hand last week Samyang announced their first autofocus lenses - for Sony E-mount. Samyang do not produce autofocus lenses for the other brands and the reason is that only Sony E-mount is an open standard, but Nikon, Canon and Pentax K-mount are not.

And I was thinking - what is Pentax make K-mount an open standard? Then it will be very easy for Samyang to add autofocus in their current K-mount lenses (14mm f/2.8, 24, 35, 50, 85mm f/1.4, 135mm f/2). In this way Pentax systems will become far more attractive because one will be able to buy modern, good and affordable autofocus lenses. Many amateur photographers will choose Pentax over Canon or Nikon and Pentax market share will jump up drastically. Ricoh will not lose anything - the sales of current Pentax lenses will not be affected because of their very compact size and excellent image quality. So it's a win-win situation - Pentax increases its market share, Samyang sells more lenses and we the customers will have a larger choice of good autofocus lenses.

So what do you think guys? Do you consider that making K-mount an open standard will be a good move for Pentax?
