Canon EF 70-300 f/4 to 5.6 L IS USM Lens $600 Two ULD elements to reduce color fringing and chromatic aberrations This is a EF mount lens that can be used with APS-C bodies to get a 112-480mm equivalent focal length To use this with the Canon R series bodies it will need an adapter. No loss of light or optics Optical Image Stabilization of up to 4 stops Fast, precise and quiet autofocus performance with manual focus override Fluorine coating on front and rear elements to resist fingerprints This is part of the Canon L series UV front protective filter has always been on the lens Comes with a Sigma 2X APO teleconverter is included with this lens. The DG series is the best performance they make. Works for about 140mm to 300mm to give you a 280-600mm lens. See photos for examples Contact me to meet up locally here in the Portland metro area.
