I currently have the Olympus OM-D E-M1. My main lens is the 12-40 f/2.8 ad I absolutely love it. The only drawback is the size at times. I have been considering getting the Olympus 17mm f/1.8 for a more compact form factor when I want/need it. I had the 17 for a while but returned it when I decided on the 12-40. I have also thought about getting the Fuji X100. Small form factor, good IQ and it has the focal length I am looking for. If I am patient I think I could get it for around $500-550. That is only a bit more expensive than the 17. Which direction should I go? Thoughts?
