What does HSM lens mean?
Hyper Sonic Motor
HSM – Hyper Sonic Motor. This feature allows for silent, fast autofocusing. It is similar to Canon’s Ultra Sonic Motor and Nikons’ Silent Wave Motor. IF – Internal Focusing. Here, the front elements inside the lens move to focus instead of all the parts.
What is the difference between DC motor and USM?
Micro USM – used in low-end consumer zooms – a bit quicker & quieter than the DC motor, no full-time manual focusing. Ring USM – used in better consumer lenses and L lenses – FAST & QUIET, has full-time manual focusing. There is a huge difference between a Ring USM and a Micro USM.
Why are Zeiss lenses so expensive?
At least part of the reason why Zeiss lenses are expensive has to do with their willingness to use the best optical glass. These glasses are expensive but if your quest is to have outstanding wide open aberration correction, then these must be used.
WHAT is STM focusing?
When you see a Canon lens with STM in the name, it means that it features Canon’s Stepper Motor technology. Canon introduced this motor design to be a quieter and smoother focus system that allows for near-silent focusing during video recording.
Are USM lenses Canon?
If you notice your Canon digital SLR camera lens has the letters USM written on the side, it means the lens has a small motor built into the body. Hence, USM is short for Ultra Sonic Motor. What this means is that your lens will autofocus faster than standard models.
What does GM stand for in Sony lenses?
Sony has created a new lineup of lenses for its full-frame cameras known as G Master (GM). These are the company’s high-end lenses that sit above its ‘G-series’ lenses and, as you might imagine, command a premium price. The first three GM lenses include FE 24-70mm F2. 8, FE 85mm F1. 4 and FE 70-200mm F2.
What is the difference between USM and HSM?
USM (Ultra-sonic motor) = Canon, HSM (Hyper-sonic motor) = Sigma, USD (Ultra-sonic drive) = Tamron. IS = Canon, OS = Sigma, VC = Tamron.
What does USM stand for?
AF: USM (Ultra-sonic motor) = Canon, HSM (Hyper-sonic motor) = Sigma, USD (Ultra-sonic drive) = Tamron. Stabilization: IS = Canon, OS = Sigma, VC = Tamron.
What is the difference between USM and USD?
USM (Ultra-sonic motor) = Canon, HSM (Hyper-sonic motor) = Sigma, USD (Ultra-sonic drive) = Tamron. IS = Canon, OS = Sigma, VC = Tamron. I realized my error after I hit send. Here in the east we just had a mild earthquake. I was a little distracted. Thanks for pointing my error out
Is there a difference between canon USM and Sigma lenses?
Some Canon USM lenses seem markedly peppier and smooth than others. Same with Sigma. (Tamron only has one USD lens so far, so hard to say there) I have Canon lenses with USM and Sigma lenses with HSM. The Canon lenses are a little faster, but you have to compare them directly to notice a difference.
