This is a better lens than the comparable one made by Minolta
5 August 2014
Summary: The reason I bought the Sony SAL50M28 lens was to get clearer magnification of small objects indoors with the assistance of two photo lamps from a light box kit. This lens is just somewhat sharper than the comparative Minolta Maxxum 50mm F2.8 lens. Overall it's a better lens than the Minolta with the same specs, but I don't think it's worth twice as much as some dealers want. I was still dissatisfied with it and bought their lighter less expensive 30mm Macro DT lens.
Summary: I'm still learning how to use this, but it is a lot of fun. It arrived ontime and in perfect condition. The lens was in plastic in the box with the instruction manual. I'm still having trouble using it as manual focus....I'm sure it is user error!
Summary: This lens does one thing very, very well at the expense of being a good general 50mm prime 2.8. If you are purchasing this lens for macro applications, I would recommend a solid tripod with intricate height adjustments and bright lights. If you are looking for a 50mm prime, opt for the f1.7 instead, it is lighter, smaller and faster on the focus.
