There are three versions of this lens, the basic design remained the same, but the STM version has a closer MFD.

Additional information (I): From Canon Camera Museum
This is one of the most popular lenses, having a long history as a standard lens. Compact and lightweight lens with orthodox 6 elements in 5 groups. High image quality with a good balance of aberration correction is obtained throughout the entire focusing range from the closest focusing distance of 0.45m to infinity. Micro-motor operated AF system. This lens was improved to become the model II by simplifying the focusing distance window and manual focus ring.


Additional information (II): From Canon Camera Museum
This is the lightest EF lens of all at a mere 130 g. Compact and high-performance, standard lens. Its Gaussian optics provide sharp delineation from near to far focusing distances. The color balance is excellent for a standard lens.


Additional information (STM): From Canon Camera Museum
The Canon compact, lightweight EF50mm f/1.8 STM offers a fast f/1.8 maximum aperture and a standard 50 mm angle of view, which is comparable to that of the human eye. In addition to maintaining the proven optical design of its predecessor, the new prime lens employs a lens coating that is optimized for shooting with digital cameras to minimize the occurrence of ghosting and flare. Furthermore, it includes a 7-bladed apertureóan improvement over the previous modelís 5-bladed apertureómaking possible impressive circular background blur that accentuates the subject.

Equipped with a gear-type stepping-motor (STM) drive, the new EF50mm f/1.8 STM achieves autofocusing that is quieter than that realized by its predecessor. In addition, a full-time manual focusing function* allows users to focus manually after autofocusing, even when the lens is in AF Mode. Delivering enhanced operability, the lens offers a minimum focusing distance of 35 cm and a maximum magnification of 0.21x, allowing users to get even closer to their subjects to make possible a wider range of imaging possibilities.

The EF50mm f/1.8 STM features a sophisticated exterior design with a premium satin-like finish, a distinctive black ring around the lens barrel and a metal mount.

Some people think the Canon 50/1.8 is better then the Minolta equivalent - it isn't. This picture shows this - even if it still is a pleasant picture.
