Design and Features
The updated version of incredibly popular Canon EF 50 mm F/1.8 II (1990). The optical formula, however, remains the same. Compared to the previous version, the lens has the following advantages:
- better overall build quality (metal mount, convenient focusing ring),
- smaller closest focusing distance (0.35m compared to 0.45m),
- the number of aperture blades was increased from 5 to 7,
- more efficient and reliable STM with FTM (older version has MM without FTM).
The lens barrel is compact, of moderate weight, made of high-quality plastic. The lens mount is metallic. The distance and depth of field scales are still missing compared to the previous version.
The focusing ring is not physically coupled with the focusing mechanism and works electronically (focus-by-wire) - turning of the ring actuates an electric motor that moves the focusing group of the lens to the proper position to achieve sharp focus.
The lens features AF/MF focus mode switch.
|AF||Autofocus mode with Full-Time Manual Focus.|
|MF||Manual focus mode.|
Full-Time Manual Focus with lenses equipped with stepping or linear motor is performed in the following way - half-press the shutter button, wait until the camera has finished the autofocusing and then focus manually without releasing the shutter button using the focusing ring.
The lens uses front filters with standard size of 49 mm which are easy to find. They are also inexpensive.
The filter thread does not rotate during focusing which allows convenient use of different types of filters (including but not limited to polarizing and gradient).
The lens is equipped with gear type stepping motor, the autofocus is quiet, smooth and fast, which is especially important during video recording. For more information on Canon’s stepping motor, refer to the article dedicated to Canon EF 40mm F/2.8 STM (2012).
The quality of the background blur of the lens is essentially the same due to the unaltered optical formula. With closing of the aperture out-of-focus highlights are now circular due to the lens diaphragm construction (seven curved blades).
