So, I am an avid Pentax guy but carrying around all the DSLR stuff has just gotten to be too much of a chore, to be honest. So, I have purchased an M10. Initial impressions: this is going to be a lot of fun and has injected some spontaneity in shooting again. Not having to lug around a bunch of stuff is oh so nice. So nice that I am debating selling my APS-C stuff (I still shoot film). I have downloaded the Supercharging book and will begin playing around to find my desired settings. Here are a couple questions I have: - The kit lens is really quite good but I am looking to purchase a portrait length lens. In APS-C, 85mm is pretty much the right length giving no barrel distortion at all. What is the equivalent of that in M4/3? I am happy, for now, with the kit zoom, but the portrait/ telephoto is a must (I have a 5 month old). Also looking for a ~20mm wide angle. - The touchscreen being so large and proud of the body makes me nervous. I am a careful person but my wife is not. I have a feeling that it will get cracked or something. Is there a screen protector or something I can slap on there? Like what you can put on a cell phone?
