What does II USM mean on Canon lenses?

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 does Canon II mean?

The only difference in the name of the lenses is the “II” designation of the second lens, which means it is the newer, updated version. Both are professional, tough L-grade lenses, but with different optics and price.


Within the micro USM sub-family there are two types: The Micro USM motor, and the Micro II USM motor. The “II” is the newer design, and is smaller (shorter). Note that this “II” does not appear in lens designations (nothing that tells the type of USM motor appears in lens deignations).

Is II vs IS STM?

STM is generally considered better if you do a lot of video recording. The II is the second version of the particular lens. If everything else is the same but the II (some have III and if I recall there may be a few with a IV) it means it is a later model of that lens. STM is a type of focus motor.

What is the difference between Canon USM and STM lenses?

USM lenses are more professional-grade and better for shooting photos, while STM lenses are geared more towards amateurs and better for video. The STM lenses really are almost silent, as they were built with video in mind.

Is a 35mm lens worth it?

35mm is arguably the most versatile focal length The question then becomes why the 35mm over any other single focal length, though. The answer is its versatility. Roughly speaking, lenses 28mm and wider might be too wide to be a real multi-purpose option that you could use to capture everything you’d want to on a trip.

Are Canon L lenses worth the money?

L-series lenses generally have better optical quality than non-L lenses. There are one or two examples of some non-L prime lenses having similarly good optics, but across the board and in like-for-like comparisons, L lenses win handily.
