I like small, light cameras and wide angle photos. I've been enjoying the Olympus 9mm body cap fisheye lens on my GM5. It's the first time I've had a camera with a lens wider than 24mm equivalent. The 9mm BCL is the perfect starter lens in this category for me. However I usually de-fish the images which is not so good for image quality, especially in the corners. So I've started to look around for the next step up in wide angle rectilinear image quality without sacrificing small size and light weight. If I stay with MFT there's the Olympus 9-18 ƒ4-ƒ5.6. Image quality is good and the images are already rectilinear. It's light for a MFT wide zoom, but still a bit more bulky than I would like. The new Nikon DL 18-50 makes an interesting comparison with the GM5 with O9-18. Weight is about the same, only a 3 gram difference. As for the size, you can take a look here: Compact Camera Meter For the Nikon Smaller size, easier to fit in a coat pocket I like the 3:2 aspect ratio for wide angle Larger aperture Smaller sensor is better for maximum depth of field, which I like 20MP good for cropping, although maybe not so good when stopped down I think not having to unlock and extend the lens would be helpful. Longer zoom range, but I don't expect to shoot between 36 and 50mm equivalent that often The Olympus / GM5 combination My GM 5 has an EVF, which I use a lot. I think I would miss that with the Nikon. Larger sensor, which may help with IQ Not having to learn new menus and settings, although I am already familiar with the Coolpix A The Olympus is about half the price of the new Nikon, but I can be patient. I expect the Nikon price to fall quite a bit eventually. Being patient is how I picked up my Coolpix A.
