I bought this lens at Moler's Camera in Wichita on the way to sit hospice with Bill, my second purchase from them (the first being the Sigma Mini-Wide II 28mm f/2.8). Given the circumstances which followed, its no wonder I never wrote about this lens. You can get one on Amazon for about $80, what this one set me back, which is really exceptional given its f/1.4 aperture. That's really what this one is all about - low light shooting and deep depth of field. That said, it can be tricky even using your camera's live view, but I almost always bring it out at least once during a shoot to highlight the subject, although its usually just quicker (and sharper) to use the auto-focus of the Canon EF 50mm f/1.8 STM. But then that's not why I use this one. Like with most lenses, its sharper > f/2.0 but I almost exclusively use it for its wide aperture. In that vein, its a bit of specialty lens, albeit one I use more often than some of my other 50mm primes. But not nearly as much as my Helios' for example.
