Thank you! I don't own any EF lenses so haven't tried any. From what I have seen from others, there is no loss of quality from EF lenses, they act and render the same way as they would on a DSLR.
At first I hit the overheating warning a couple of times but since the updated firmware, I have not run into issues. I also shoot in small B-roll Burts so I'm not running the camera for long interviews etc.
I live in Australia and we're going into summer here so I can't test that. I don't see why not though, it's weather sealed and I think it's rated to handle pretty cold weather. Majority of cameras, especially modern ones don't have any problems in the cold.
Ich hab letzte Woche eine bei Kleinanzeigen gekauft. Neu. Mit Rechnung. 6500€ mit 24-70. laut sendungsverfolgung kommt sie noch diese Woche an. Bei Interesse geb ich gern ein Update wenn sie da ist ob alles gut lief und wo ich sie her habe.
I am using the LUTs Canon provide for C-LOG conversion on the R5 footage. They are free to download and then I do my own colour corrections and grades.
