Trainspotting with the 40mm M-Rokkor and Sony A7r

sony a7r 40mm m-rokkor leica

Here are some test shots with the Minolta 40mm f/2 M-Rokkor for the Minolta CLE. This is the multicoated version of the Leica 40mm Summicron-C. We used the very compact 40mm M-Rokkor walking around a local train museum with the Sony A7r via a Leica M lens adapter. The shots up to the handcart are all done at maximum aperture of f/2. Manual focus was very easy with using the viewfinder magnification of the A7r even in the mid-day sun. The mid-day sun also guaranteed high shutter speeds at ISO 100 and f/2. All the shots are handheld.

The shots below are at f/5.6 up to f/11. We need to test this lens more but the sweet spot is definitely at f/5.6.

The CSX 152 (GE AC4400CW diesel-electric locomotive) and the CSX 7305 (GE C40-8 [Dash 8]) was shot during the afternoon sun.

The lens has been great on the Minolta CLE and NEX-7 and it performs well on the full-frame A7r. The lightweight and compact 40mm M-Rokkor with a fairly fast f/2 aperture should always be considered for the A7 if you want to try Leica M lenses.

How To Install OpenMemories AppStore

Image
OpenMemories App Shown on Camera's Application Tab DHI Enterprises shows us how to install a third party application for Sony Cameras which support the PlayMemories Camera Apps. The third party OpenMemories AppStore can now be installed using the same method shown. WARNING from the OpenMemories AppStore developer: Is it safe? This is an experiment in a very early stage. All information has been found through reverse engineering. Even though everything worked fine for our developers, it could cause harm to your hardware. If you break your camera, you get to keep both pieces. We won't take any responsibility. However, this seems to be safer than tampering with your camera firmware directly. We're just interacting with the isolated Android subsystem. Apps you install this way can be uninstalled in the applications manager. In the worst case, a factory reset of the camera clears all data on the Android partitions. How To Install OpenMemories AppStore on your Sony C...
