    Yes indeed. It has been true ever since digital dark rooms came into being. The later versions have become more sophisticated. The paintings were always the artist's interpretation for that matter. SuryStatistics: Posted by sury — Sun Sep 27, 2020 5:30 pm

    This reminds me of the age old discussion of whether enhancements enrich photography or detract from it. RAW files have too much capacity for one to set the camera perfectly. So we have programs like Lightroom and Capture One to provide the rest of the settings. Luminar 4 seems different. I guess the end product […]

    You can replace any element in your photo with one of your own. If you have a beautiful sky and need to replace the ho-humbeach, it can be done. It is not a preset of enhancement/adjustment. It is literally replacing the original sky with a new image.The AI portion detects where the horizon is, and […]

    Is there a stock beach that you could use as well? Is the stock sky a preset of enhancements to your original or is it a replacement?Thanks,JTStatistics: Posted by jbtaylor — Sat Sep 26, 2020 2:36 pm

Sigma launch mount switching service

SIGMA is going to start a new “Mount Conversion Service” which will enable Sigma to convert the mount of customers’ Sigma Art, Sports and Contemporary lenses from one camera fitting to another.

120-300mm-f2.8

The ranges convertible include the new Sports models such as the 120-300mm f/2.8

“We believe that a lens is not only such a key device for photographic expression, but also an important resource for photographers”, they say. “It has been our hope to develop the lens system that is genuinely photographer-centered, and you can enjoy it for a longer period of time. As an experienced lens manufacturer that has been creating a diverse range of interchangeable lenses, our desire and know-how is crystalized in this unique service. With this service, the mount of your SIGMA lenses can be converted to another mount system, depending on the specification of camera bodies. This service will be available from September, 2013.”

Editor’s comment – this feature of the new Sigma lens designs was not even mentioned at photokina 2012. They have kept something under wraps which must have been planned from a very early date. The main lens unit of all Sigmas in these series has to be effectively independent of the mount, with electronic protocol conversion chips to handle aperture and focus operation while different rear assemblies change the bayonet.

“Interchangeable lens camera systems appear to be superior in offering photographers more options, allowing them to change lenses freely and have more flexible photographic expression”, states the Sigma release. “Nevertheless, each interchangeable lens is limited with the specification of different camera systems. In other words, you can’t use those lenses if you change it from one type to another. Although lenses are the key devices to create photographic expression, it is a shame that there is no system that purely sets the standard based on the functions and individual qualities of interchangeable lenses.

“In this circumstance, SIGMA is going to start the “Mount Conversion Service” from 2nd September 2013. Our goal is to provide more freedom for photographers so that they can select new camera bodies without worrying about the conventional limitation around the mount system of cameras, and keep on using their current lenses by adjusting them to fit with a new mechanism.”

For the details, please check the Sigma website //www.sigma-global.com/en/lenses/cas/service/mcs/index.html * This “Mount Conversion Service” is different from a normal repair. In order to apply for the service, please contact your nearest authorized subsidiary / distributor of SIGMA.
