These are semi-apo objectives with better correction and higher NA (resolution) than Achromats. Excellent choice for finite microscope systems, but also works great as macro - bellows lens for studio macrophotography / stacking, producing high-resolution, high-contrast image with very good color correction.
Resolution wise, it is virtually on par with the Mitutoyo 5/0.14. Bear in mind though that just like the vast majority of high-resolution objectives, the image circle is not big enough to cover large sensors. On APS-C coverage is not perfect, but good and more than usable, at higher than nominal magnification coverage improves.
Perfect for m4/3 or smaller sensor cameras. Comes with RMS-M42 adapter, ready to be mounted on virtually any bellows or extension tubes via simple and cheap M42 adapter or directly if you use M42 system. Body shows normal signs of wear and age as shown, nothing major though. 100% tested, clean optics, no scratches, delamination or haze.Comes in plastic canister + RMS-M42 adapter.
