Sony E 55-210mm + Raynox dcr-250
Canon FD 100-300mm is an old manual focus lenses, over 20+ years old. It is big and heavy, but when nail the focus, the result images are very good. The photos below are using Canon FD 100-300mm + raynox 250 filter.
I have purchased couple of used lens over this holiday. The Samyang 12mm and Song E 30mm Macro. The 12mm has arrived first. I took several pictures using it, initially, it looks promising.
