Canon patent for a lens with two mounts, can be reverse mounted for macro

jpa_428206568_000002

We may soon see Canon lenses with mounts on both ends. Such a lens could easily be “reverse mounted” on a DSLR, something you usually do with adapters. By reverse mounting a lens you get a strong macro lens.

However, when using reverse mount adapters, you loose all connectivity and hence all electronic settings like AF or automatic aperture and exposure settings are not working. Canon’s patent shows a lens with electric contacts on both ends and that can be mounted in two ways. One lens could thus be used as standard lens and as a very powerful macro lens. Pretty cool, I think. Really hope this patent goes into production soon.

Adobe Lightroom CC 2015.8 released, adds EOS M5 support and tethering for EOS 5D Mark IV

Above: an overview on “Reference View” in Lightroom CC 2015.8 by LoriGraceAz

From Adobe Lightroom Journal:

Today Lightroom CC(2015.8) / 6.8, Adobe Camera Raw 9.8 and updates to Lightroom for mobile are now available.  Please click here to read the Camera Raw release notes and click here to read all the Lightroom for mobile news.

Introducing Reference View

Reference View is a new view mode available in the Develop Module that allows you to compare 2 different images in order to make them visually consistent.  This is helpful when making a group of images from a single event look similar or setting the white balance appropriately in mixed lighting conditions.

To get started,

  1. Go to the Develop Module
  2. Click on Reference View.  Its on the Toolbar, and you may need to show the Toolbar if hidden
  3. Drag and Drop your Reference Photo onto the left pane.  You can change your Reference Photo by either dragging a different image onto the left pane or using the “Set as Reference Photo” context menu in the Library Module.
  4. Edit the active photo. Use the Reference Photo to guide your editing decisions.

Click here for more information on Reference View.

Performance Improvements

Lightroom CC (2015.8) / 6.8 includes ‘under-the-hood’ changes designed to improve the responsiveness of your Lightroom experience.  You should notice improvements in image editing responsiveness when background tasks (such as Preview Generation) are running, moving files between folders, running catalog backups.

Fit/Fill Improvements

You can now zoom to fit and zoom to fill.  Particularly when using ultra high-resolution (i.e. 4K and 5K) monitors, prior versions of Lightroom would not completely fill the Loupe window.

Additional Features

  • Ability to filter or create a Smart Collection for images that have Snapshots associated with them.
  • Export a Collection Set as a new catalog.
