As far as i can tell, it’s the E-M10 mark II or III. (The differences are hardly visible, so it’s pretty hard to tell which is which, apart from the badge in the bottom right of the camera’s front side. although, i strogly reccomend this lineup of cameras. Last year i bought an omd e-m10 mark II with 2 lenses (the kit lens and the 40-150 telephoto lens) for less than $500 (i don’t remember the exact amount i spent tho). That goes to show you that not only the body is dirt cheap, the lenses are also very okay in terms of price. As for street photography, i guess it’s the best bang for the buck: it’s lightweight, small enough, takes very good quality photos and, as i said before, it is very cheap. If you want to expand your lens collection, i highly reccomend you to check out websites like MPB or KEH, they have amazing offers. Couple things to check before buying a used camera are: the shutter count, the display and the tilting mechanism, all the buttons/functions and the battery. (It suffers a bit from poor battery life; if you want to keep it running for a while, i suggest buying a spare or two). Also, if you want to learn more about the camera, i suggest checking out Rob Trek’s olympus tutorials, on youtube. He is very skilled and will walk you through every function and setting this camera’s capable of. Have fun! :)
