To my opinion, this is the best landscape picture I ever took. A couple years ago, I was hiking across the French Haute Savoie with my girlfriend, when this thick fog/cloud surrended us and framed the peak of this mountain (the Dent d'Oche)
Back then, I was still using my old A7II and 24-70 F4 (I might also have used a 70-200, I don't really remember, I just know that I had to zoom). The picture was then edited on Adobe LR and I added the birds on PS.
