Although it is expensive in the catalog ninap, it is functional satisfactorily. The overview is also minimally cheap. Although there are many choices of design and size, we will not limit the users, but weak points are a weak point of net sales that we can not try on. Also, since there is no particular problem as it is not used, one of the functions "angle adjustment of the lens" can not be done absolutely. There are usage methods and diagrams inside the outer box, but I do not know even if I see it. Although it seems that a part of the frame seems to be bent, it was impossible to bend at all either side even if putting strength (I tried many times). Although it seems likely to be damaged even if putting much effort, I stopped, but I think that it is not necessary function. I also requested, but I'd like you to update photos such as mirror type as soon as possible.
