Hey y'all. I just picked up an Oly EM-5 but I've been shooting with a Panny GX1 for close to a year now. On that camera I've been using the Oly 17mm f/2.8. I want something in the same focal length but a bit faster since a lot of my shooting is done in low-light situations. Below are some examples of what I shoot. So, as you can see I shoot with mostly available light and long exposures. Now, one thing I will say about the Oly 17mm f/2.8 on my Panny GX1 is that it takes some amazing detail/macro-like photos and I'll be keeping this oft maligned lens. On my Nikon D5100 I use a 12-24mm f/4 lens--which I like a lot (that'd be 18-36mm range). So if I could find something in that range, but faster, for the Panny and Oly, I'd be very happy. TIA!
