I invested into the M system this October during their massive refurbished sale. I'm extremely pleased that I went with the M5, as it's a great travel camera. The 15-45 lens is ultra compact and light, which is great news, but the aperture is slow - I get the compromise. My biggest reason for buying this lens was it's 24mm equivalent FOV. It's my favorite wide angle focal length. My plan is to swap to the 22mm f/2, adapted 50mm STM (looks very cool mounted) and a manual 35mm lens for low light stuff. So if this lens comes out...I may be first in line to get it! An f/1.8 or f/2 15mm would be sick. However, I'd take another pancake lens too. The 22mm is lovely.
