So I have room for bringing to complimentary systems with me in my new Lowepro Nova Sport 35L. I always try to keep things simple and practical. I am most certainly bringing my Sony A7 as one system. *Probably* with the following lenses (advice welcome--cf. the lenses in my signiture): Sony A7: Voigtlander 12mm f/5.6 Canon FDn 20-35mm f/3.5L Voigtlander 35mm f/1.2 Canon FDn 85mm f/1.2L The second camera is the main question, however. Taking up roughly the same amount of space in the bag, I could either bring: Olympus OM-D E-M5: Olympus 9-18mm f/4-5.6 (comparing the 9-18mm to the 20-35mm has been on the to-do list for a while) Panasonic Leica 25mm f/1.4 Olympus 75mm f/1.8 OR Mamiya M645 1000s: Mamiya Sekor C 80mm f/1.9 So digital micro four thirds vs. medium format film (Fuji Neopan). One slows me down even further from the manual focus on digital one provides me with much more convenience. One is very practical, compact and lightweight and the other is, well, heavy and awesome. I really can't decide and I leave on Wednesday. Opinions anyone?
