How can i use Nikon D 7100 and Panasonic Lumix DMC-LF1 with Photoshop CS 5 Camera Raw?
The one needs 7.4 (or better), the other 8.1 (or better), so Photoshop CS5 with ACR6 is not up to the task.
The free DNG Converter could be used to convert the RAW images to DNG which your version of ACR should be able to process.
