Ebay listings for this model is filled with lensless camera bodies and defective units. It is also filled with nonfunctioning lenses for sale. I regard this as a case of poor production design or poor quality control. I think later models have solved these problems, but I recommend staying away from this and the 1V1 which has the same lens problems.
The problem is with the lens itself. Modern lenses require good electrical connections since mechanical ones are a thing of the past. I tested the camera with lens that work and performance is excellent. I’m sending off two lens for repair despite receiving no communication from Nikon. I’m sure they’re very busy. I’ll have more if and when this is resolved.
If you test your camera with a lens that is known to function properly you should find that the defect is in the lenses. I have the identical problem with a 10-30mm and 30-110mm lens I purchased used. I contact acted Nikon about a remedy and I have yet to receive a reply. That was two weeks ago and I am not holding my breath. This represents terrible production and quality control.
