I haven’t had great luck with the used Canon EF 100-300mm f4.5-5.6 USM lens I bought a few months ago. Though, a lot of the problems so far are from not having enough light to try smaller apertures hand held. On this photo outing I was able to get out in the field early enough and brought along a tripod plus a wired cable release. The YouTube video you can see visuals of the photo outing. Get the Viltrox Speedbooster on B&H or Amazon . Get the Canon EOS M5 on eBay , B&H or Amazon . Get the Canon EOS M50 on B&H or Amazon . Look for the Canon 100-300mm on eBay here .

I was using the Canon EOS M5 for photos and the M50 for video. I walk around a snow covered state park to try out this combo so that I could better learn what the lens is capable of along with just enjoying photograph...
