This is my first time using a Lensbaby product and honestly just off first impressions I am blown away by the incredible build quality. It features a good amount of heft to it at 18.7oz. Which is far from the heaviest 85mm out there, but still provides excellent usability. The construction is solid metal down to the lens cap and has held up nicely despite being tossed around in my camera bag or bumped when carrying my 5D IV. Honestly, the only gripe I have about the build is the mount portion.
