About Nikon V 1, Panasonic GX 1 and Olympus EPL3.

As far as micro-orders are concerned, Nikon's system is the most fragmented and can be ruled out first.

Compared with EPL3, GX 1 has better fuselage performance and image quality than EPL3 ~ ~ but the price you asked is very suspicious. 1750 it's good to get the fuselage. 1442 lens only 1750. I think it's the color difference. When you trade,

In terms of lens, a zoom of 1442 and an Olympus 17/2.8 can basically meet the shooting needs of most occasions. If you have a high demand for image quality, you can choose Panasonic's "God Cake"-20/1.7 fixed focus (both humanities and tourism) or Olympus 45 (bust) according to your own shooting preferences.

It is recommended to visit the second-hand trading area in Jule.com where the old ID has been mixed in the forum for a long time (the original "4/3.com" should be the Chinese website with the most concentrated users of Oji and Panasonic's 4/3 system), and the character is relatively guaranteed in all aspects, and the transaction is also guaranteed. Taobao can also be considered. You can find a shop called Dongdong Liangbao, which is an old shop that has been making Olympus and Panasonic 4/3 system products for many years. A lot of old O powder "smuggled drugs" from him, hehe ~ ~
