eTone 8X Foucsing Loupe Lupe Toyo Linhof Tachihara Ebony 4x5 8x10 Large Format Camera

So happy to find this. Easy to set up adjusting the optics because I wear glasses and is sharp and bright edge to edge. Also very affordable in fact I thinking about buying another just incase I ever lose his one.

Feels well built and works well.Optics are nice and clear

Dim optics, with terrible distortion that makes focusing difficult. No actual way to make diopter adjustments. The answer above doesn't work because the barrels unscrew from the grip, and the viewfinder doesn't have any lenses in it so adjusting that doesnt make sense.
