Hi I have tried to connect my Canon EOS Ra with Maxim DL 6.3. The camera was not found even linked with an USB Cabel. Will an up-date to Maxim DL 6.4. solve this problem?
The Canon EOS Ra is not compatible with MaxIm DL Pro - none of the mirrorless cameras will work as Canon changed all software tools, file formats, and was late getting documentation and tools available. It will not be supported in future. You might look for ASCOM drivers and try them.
