The User's Review: Elicar V-HQ Macro MC 90 mm f/2.5 Macro Lens

I believe, this lens is one of the best macro lenses for manual focus, because of its 1:1 magnification scale, f2.5 maximum aperture, and smaller size. My copy has a KA mount, meaning that I can set aperture size on Pentax DSLR camers when using the A gear on the aperture ring on this lens (it has the A position, but no A-lock commonly seen on Pentax KA lenses).
