Canon FDn 85-300 / 4.5 Zoom Lens, mint condition, huge 77mm front end. Very sturdy construction / very heavy, which I like to minimize movement. Initial arrival function & IQ test shots for color rendition, detail capture, and bokeh look very good. Everything functions as it should. Very impressed with this lens so far...seems to be in the same class as the Canon FDn 300/4.0-L and 400/4.5 If nothing creeps out of the woodwork I think I just got one heck of a lens Will be wringing it out the next couple days, including testing it with the FD 2x-A Extender. Then weather permitting, plan to use it for the next Full Moon over the upcoming weekend in January...hoping the utility of the Zoom will help frame / get some moonscapes at a local lake. Anyhow...a few quick common backyard shots so far...the Cardinal is a bit soft but that's not the fault of the lens, LOL...I kept it as an example of another test of a different color.
