The Minolta 50mm 2.8 Macro. This oldie doesn’t have a nickname but it doesn’t need to. Here’s what it does have though…1:1 magnification. Many of today’s zoom lenses have the word “macro” written somewhere on the lens. It’s somewhat misleading and in best case scenario gets you as close as 1:4. Moreover much of today’s dedicated macro lenses have a maximum magnification of 1:2. Serious macro photography requires 1:1 magnification.
The most popular focal distance is 100mm. The smaller the focal distance, the closer you must be, which essentially means there is less natural light to work with. This is one reason why the 100mm is usually preferred over the 50. However, if you put a 50mm on an aps-c sized sensor, such as the Sony a77, that gives a FOV equivalent of 75mm. This is a nifty tradeoff since this lens fits in your pocket. Minolta did make a 100mm 2.8 Macro lens that some considered to be THE best macro lens period.
The biggest plus is you can find this lens going on ebay for half the price of either the Sony equivalent, which is the same optically, or the 100mm Macro. As a bonus, the 50mm macro can double up as a medium portrait lens good for 1/4 body shots.
