Olympus epl6, Samsung nx3000 or Sony a5000, which is better? Give me a reason.

Among these machines, A5000 is unable to stand out because A6000/A5 100 is too excellent; E-PL6 is a consistent EPL series, with good reputation, high cost performance and appearance in line with most people's ideas, so it sells well; NX3000 may not have the low-end line difference of Samsung, but it is not necessarily the best choice.

To sum up, EPL6 and A5000 are both acceptable, preferring the former; Also look at A5 100 or Canon EOS M or M2. Although the focus is really poor, the price is reasonable and the accessories are suitable, which is actually quite good.
