This is an Original Olympus-Zuiko 300mm f/4.5 that i have used for Sun Eclypse photo, and for wide field Astro Imaging.
The quality of Zuiko lens is well known; this particular lens has been carefully selected for sharpness, flat focus, colour correction and stability. I have used if for eclypse chasing, but my health is now precluding those exotic trips for me...
It comes with a matching original 2x Teleconverter, giving a further option: 600 mm f/5.6 theoretic, f/8 to be more honest.
I have used it, either full open or slightly stopped, on wide field starfields, and there is no blame at all on the superb quality of this optical combination.
The front and the back lenses are absolutely clean, fungus exempt, and there are no scratches at all. A few cosmetic scuffs (no dents!) are showing on the outside of the (included) sun shade and on the body, as for every honest workhorse.
