I've tried several lenses, including the expensive and popular moment lens. I was totally unimpressed the lens flare was incredible. I do real estate photography for a living, hundreds of listings a year. And I need a dependable lens, and when I found Sandmarc I was cooking.My photography is better, my clients are happier. It's a win-win win win. Pick up a Sandmarc Lens ASAP. Best yet made in the good old US of A! Keep up the good fight ! Thanks Sandmarc! Best Devin S.
