What’s 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. Their focus speed, while a tiny bit slower, is also better suited for video as it is smoother and less “jarring”.
Is USM better than STM?
USM vs STM USM lenses are much faster than STM lenses, which makes USM a better choice for action photographers, street photographers, and wildlife photographers. USM lenses also offer smoother manual focusing, given the mechanical connection between the focus ring and the focusing mechanism.

Which lens hood should I buy?
A Cylindrical Lens Hood will generally work well and get the job done. These are often used with a prime or telephoto lens and will completely block stray light. Even more popular are Petal Lens Hoods (sometimes called a Tulip Lens Hood). These are shorter lens hoods that have curved notches.
Are Canon USM lenses focus by wire?
Canon changed the name of the game when they created the Nano USM. It has a new type of mechanism that combines the speed of a Ring USM with the silent focus of a lead-screw type STM lens. However, like the STM motor, it requires focus-by-wire (the manual focus ring is not connected to the lens focus system).
Is the canon 18-135mm STM a good lens?
The Canon 18-135mm STM is a great do-everything lens with effortlessly silent and extremely fast autofocusing. The older 18-135mm EF-S IS lens was the only lens I needed to shoot everything for two weeks in Maui in 2010.
What is the distortion on the 18-135 STM lens?
Distortion results are similar for the 18-135 IS and 18-135 IS STM lenses. The 18-135 STM shows nearly no flare over the entire focal length range (except at around 35mm) with a wide open aperture. Only slightly more flare is apparent at f/8 and slightly more at f/11 and f/16.
How good is the EF-S is 18-135mm?
Another huge improvement from the older 18-135mm EF-S IS is that the zoom range from 24mm to 18mm has been spread-out on the zoom ring, so it’s much easier to set precise wide-angle framing. On the old lens, it was very cramped at the wide end.
What is the maximum magnification of the 18-135 STM?
Maximum magnification specs, as usual, increase with extension tubes. The 18-135 STM’s magnification range numbers for the Canon EF 12mm Extension Tube II are 0.43-0.09x and 0.61-0.21x for the Canon EF 25mm Extension Tube II . This lens is not compatible with Canon Extenders.
