A used em-5 right now in my part of the world is around 450usd, body only, which is cheaper than the e-em10 which was my cheaper alternative to the gx7 that I now realize is a bit over my price range. Initially I wasn't interested in buying a used body but budget limitations has made it quite an attractive little package for me. Now I'm considering it as a serious option, I do have a few questions since I've been into m4/3 for a few years now (epl-3, gx-1 and currently own gf-3), I haven't really been paying attention or keeping up with what's going. Firstly, I know enough to know the e-m5 was and still is a big deal in the mirrorless world so I'm a little skeptical on the price drop. I've only had a quick look but it does seem 450usd is about the norm for a body which seems like quite a steep drop for such an advanced body, even if it has already been out for around 2 years or so. Second, I will be giving it a thorough check but are there common issues with this model I should know about, perhaps a certain batch with issues that I can identify through the serial or date of manufacture? I already know about the cracked LCD's but I'm not familiar enough with to know if there's anything I should be paying attention to. Next, from users of the body, if given the option should I go for ones with the hand grip? I've had the epl-3, gx-1 and gf-3 and I've never felt like I needed anything more to help me with the grip on any of them. I use my gf-3 regularly with the old 14-140 and never have problems with the weight. I don't know if I'll need the extra ergonomics on the e-m5 which is already a larger body to what I'm used to working with. Additionally, is there any way to check the weather sealing, or if it's been tampered with without opening it up? Thanks in advance, I'll be doing my own research on this but additional info and opinions are always welcome.
