Design and Features
Sony 100mm F/2.8 Macro is one of the lenses from the Minolta era. Of course it was redesigned to match the modern Sony Alpha cameras, but optically it remains the same as older Minolta 100mm F/2.8 Macro.
The lens barrel is of moderate weight, made of metal. The lens mount is metallic.
The lens lacks focusing mode switch, therefore you have to set the automatic or manual focus mode from the camera. Direct Manual Focus is available.
During autofocus operation, you can press the AF Stop button of the lens to temporarily pause autofocus. This lets you stop autofocus whenever any unwanted obstacle comes closer to the camera than the moving subject you are tracking. If the shutter button is still pressed halfway when the AF Stop button is released, autofocusing will continue as before. The AF Stop function also works in continuous autofocus mode. You can change the functions of the AF Stop button using the camera's custom functions menu.
The lens features focusing distance range limiter which allows to choose between the following focusing distance ranges:
|FULL||Full range of focusing distances.|
|0.35 m - 0.54 m||Range of focusing distances suitable for shooting nearby subjects.|
|0.59 m - ∞||Range of focusing distances suitable for shooting distant subjects.|
By setting the suitable focusing distance range, the actual autofocusing time can be shorter.
The lens uses front filters with standard size of 55 mm which are easy to find. They are also inexpensive. It should be noted that most lenses of the system have such diameter of the filter thread, that is why if you will purchase additional lens with similar focal length and/or speed, you probably will be able to share filters between them.
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 incorporates a floating system that provides correction of aberrations and ensures constantly high image quality at the entire range of focusing distances from infinity down to the closest focusing distance. Learn more
