Just would like to share my experience of my family buying used camera and lenses in Japan for future buyers.

My parents were the one who bought my gear while I stay at our home country. My parents have 0 knowledge when it comes to camera so the fear of buying the wrong model or a damaged unit is there. Fortunately, the staff at Map Camera were helpful and patient and were able to provide all the camera list I provided for my parents for ease of transaction. I used mapcamera.com as a reference for the availability and price and it was quite accurate to the physical shop. I manage to buy a used Sony A7RII and Sigma 35mm F2 and a brand new Sony 85mm F1.8. Yes the camera body is in Japanese but there is work around it if you search on the internet. After almost a month of usage, no hidden problems from body and lenses and they are all working well.

I hope this would help your research and confidence on buying used camera in Map Camera.

Feel free to ask questions!
