15/6/2012 · If you’re a using a USM lens in video with AF, when the camera tries to refocus, you will experience a sudden jump, which will make this part completely useless. The thread you mentioned is really helpful. And I have another question, does STM use focus-by-wire?

25/8/2013 · Keep in mind, it’s not perfect: as one Redditor pointed out, the 40mm f/2.8 STM used in the video has a greater depth of field wide open than the 50mm f/1.4 USM, meaning it needed to focus a lot

Canon autofocus lenses have long focused on speed and not so much on the smooth and quiet operation. This is what we know today as USM (Ultrasonic motor). As usage of DSLRs for video became more popular, Canon introduced STM (Stepping motor) lenses that provided a smoother experience; albeit at a slight disadvantage on the speed side.

Canon is improving day by day with all the new technologies used by the company. There are three focusing motor technologies, in which USM and STM are highly popular. If you want to know exact difference between Canon STM vs USM lens, then you should

USM stands for Ultrasonic Motor, while STM stands for Stepper Motor. Both are autofocus motors built into different lenses you’ll find in Canon’s lineup. General opinion seems to be that USM lenses are more professional-grade and better for shooti

4/1/2018 · I just watched a video by Canon on their STM technology in their lens. Is the plan to put STM in the L lens because it is quieter for video as well as does a nicer job locking into focus in a changing environment? I am looking for an explanation into the logic of USM

Nano USM is Canon’s latest innovation in focusing technology. Announced in early 2016 it combines the speed of Ring-type USM with the quietness and smoothness of STM. The features of this type of motor make it ideally suited for capturing fast action and movies where quiet and smooth focus are the ideal characteristics for focus.

Das sind STM, USM und der eher konventionelle DC Motor. Sehen wir uns die Unterschiede zum Verständnis genauer an, damit Sie das ideale Objektiv für Ihren Bedarf finden können. STM STM Objektive sind hervorragend für Fotos geeignet, aber noch besser

19/4/2014 · As you can see, STM lenses are, as I originally pointed out, aimed at video users. There are no benefits to STM over USM for those who do not shoot video (except possibly when using liveview on the latest bodies) and there are some downsides (slower AF in

What do the letters USM vs STM on Canon Lenses mean, USM vs STM Which is better. USM stand for Ultra Sonic Motor. Canon introduced this motor design to be a quieter and smoother focus system that allows for near silent focus during video recording.

STM is meer geschikt voor video, onder andere omdat de lichte tik van USM niet aanwezig is en omdat scherpstellen (in combinatie met contrastdetectie) makkelijker is. Wanneer er sprake is van snelle actie, zoals sportfotografie, is een ultrasone motor (zoals USM) superieur aan een stappenmotor.

8/9/2017 · It really works in practice too with the EF-S 18-135mm IS USM feeling much snappier than the previous EF-S 18-135mm IS STM model for sports, but remaining smooth and inaudible for video work. The EF-S 18-135mm IS USM also features rack gearing on the

Another huge factor in video shooting is that the AF operation is nearly silent — very important if a microphone is attached to the camera, and vital if using the camera’s built-in microphone. Nano USM matches the relative silence of previous STM designs when

I’m purchasing a Canon 6D Mark II and am thinking about getting an EF 24-105mm lens for it, but I am unsure of whether to get the L lens that is USM or the other one, which is STM. I’m likely going to be shooting video more often than using it for photography– I

Canon’s STM lenses are aimed at videographers. The Stepper Motor (that’s the STM) promises quiet operation while shooting video. But how do the produced noise and the speed compare to Canon’s USM (Ultra Sonic Motor) lenses?That’s what YouTube user marconilanna tries to find out in the video
