Generally the Industar lenses are of Tessar construction, not so bright but quite good resolution and contrast. I don't know this particular one but it seems suitable for macro work (manual aperture and recessed multicoated lens). However F=16 might be not enough to get reasonable DOF in some cases. IMO every lens supplied with bellows or tubes can work as a macro, especially when reversing ring is used (slightly improves resolution over 1:1). Zbig.
