I'm thinking over my current gear this year, definitely still a fan of the 35mm FOV, and since the Olympus 17mm f1.8 is too expensive for my taste, I will stick with the f2.8, which I still quite like anyway. But then I have this Sigma 30mm, which always impresses with its sharpness and overall image quality, but I can't seem to get to be friends with the focal length. I've always enjoyed images shot with the 50mm focal length, even though I'm more of a 35mm guy myself, and I'm wondering if the Olympus 25mm "looks" significantly different from the 30mm, enough to justify the purchase (I'd probably sell the Sigma). 1. I want a little more in the frame than the 30mm lets me get, and 2. I know I could use f1.8 to my advantage over the Sigma. But it really comes down to whether the focal length feels different enough to justify the upgrade. I've been debating upgrading body this year instead, but will probably only do so if I see the GX7 at that nice low $399 price point it was on eBay a little while back (wish I hadn't missed it).
