>>3627788Olympus sounds perfect for your needs desu unless you need lots of bokeh which is completely overdone and cliched at this point).
I recommend the 25mm F1.8 lens by Olympus as a good starter prime.
>>3627762Crop sensors are amazing if you actually want things in focus. Look at the range you get at F8: everything fro 1.5 metres to infinity and with a great focal length of ~42mm. Full frame is a meme.
