What is a nano lens?
Nano USM lenses use a motor system that combines the benefits of a ring ultrasonic motor (USM) with a lead-screw type STM (stepping motor). Compared to the previous Canon 18-135mm lens, this new one has faster autofocus speeds — up to 4.3x faster on the telephoto end and 2.5x faster for wide-angle.
Is Nano USM lens?
Nano USM (ultrasonic motor) is Canon’s latest generation of lens motors, combining the speed of USM motors with the silent action of their STM motors.
What is Nikon Nano?
Nano Crystal Coat is an anti reflective coating that originated in the development of NSR-series (Nikon Step and Repeat) semiconductor manufacturing devices. Nikon now proudly marks a world first by applying this coating technology to a wide range of lenses for use in consumer optical products.
IS USM Nano vs STM?
Nano USM addresses the shortcomings of STM, provides the speed of USM, and has the smoothness of STM. The performance of Nano USM is based on the similar ultrasonic vibration converted into movement methodology that USM has employed for some time.
What does 18 135mm lens mean?
Zoom lenses have these two numbers, this simply indicates the lens’ range of focal length, with 18mm representing its widest angle of view and 55mm (or 135mm) representing its narrowest angle of view. The 18-135 will give you many options, but 135mm will not be enough zoom for some wildlife photos.
What is a Nano USM lens?
Nano USM (ultrasonic motor) is Canon’s latest generation of lens motors, combining the speed of USM motors with the silent action of their STM motors. If you’ve heard news of a new Nano USM lens and I haven’t listed it, please let me know below.
What are nano crystal coat microscope lenses?
Lenses that require light from an oblique angle allow observation of a subject with a brighter view, which made the coating sought-after in this new field as well. Nano Crystal Coat technology was applied to microscope lenses. The result was objective lenses with excellent light transmission across a wide range, from ultraviolet to infrared.
Is nano-optics the new microelectronics for Photonics?
To keep up, photonics must match this breadth of application and ease of use. Now a relatively new optical technology, nano-optics, is bringing photonics the optical alchemy it needs to complement microelectronics. Nano-optics addresses every shortcoming of bulk optics mentioned above and shares the key strengths of microelectronics.
What are nano usmfocusing Motors?
0 Canon’s Nano USMfocusing motors have so far been used in the EF 18-135mm f/3.5-5.6 IS USM and EF 70-300mm f/4-5.6 IS II USM lenses. It is a type of AF motor that, like Ring USM, uses micro-piezo vibrations to move the lens focus elements.
