Congratulations on the new camera, u/aefjor! Yes, 17mm is an excellent focal length for micro 4/3.
If you want an autofocusing 17mm and budget permits, I recommend the Oly 17mm f/1.8 for its superior low light performance.
If you don't mind focusing manually and the Voigtlander 17.5mm f/0.95 is too expensive, you might also want to look at the $339 SLR Magic 17mm T1.6 [Referral Link], which comes with a variable neutral density filter.
Here are a few examples shot with this lens and micro 4/3 cameras:
Hope this is helpful and Godspeed with your new G7.
