As expected, very good image quality. With 1 OLYMPUS EX-25 Extension Tube (25 mm) image full format lengths realized from approx 13 mm. In this setting, there is the risk of touching the object with the lens. As a lens protector, I recommend to use immediately an appropriate UV filter (52 mm) as a permanent lens protector. In good light conditions, reducing blur freehand shots to Aperture 5.6 are quite possible with a smaller aperture or a tripod of suitable lightning are recommended. In close vicinity of the autofocus often works several times over the full adjustment range. If successful, razor-sharp images, but here is the manual adjustment often faster (ED lens!). Lens is also combined with 2x teleconverter and teleconverter and above intermediate ring or vice versa. Conclusion: Very good, not repentant purchase!
