Both lenses have image stabilization (IS). The EF 24–105mm f/4L IS USM and IS II USM version use a ring type ultrasonic motor, whereas the new EF 24-105mm f/3.5-5.6 IS STM uses Canon's STM stepper motor, which is quieter during video usage. The new EF 24-105mm f/3.5-5.6 IS STM weighs slightly less (525 g / 18.52 oz versus 670 g / 23.6 oz) and Canon. EF 24-105mm f/3.5-5.6 IS STM.

The EF24-105mm f/3.5-5.6 IS STM is the first EF lens to come equipped with a lead-screw type stepping motor (STM). It also features a full-time manual focus mechanism that allows for manual, minute focus adjustments. The motor is highly responsive, allowing for quick and smooth AF. It is also silent, making it ideal for movie capturing Focal Length & Maximum Aperture: 24–105mm 1:3.5-5.6. Lens Construction: 17 elements in 13 groups. Diagonal Angle of View: 84° - 23° 20'.

The lead-screw-type is super-quick and super-silent, whilst the gear-type is designed for compactness, to work in much smaller lenses. The gear-type does still produce a low level of residual noise, as a result of the gears which are doing the work. ABOVE: Gear-type STM. Težak svega 525 g, EF 24-105mm f/3.5-5.6 IS STM sjajan je suputnik. Fleksibilan raspon zumiranja – od širokokutnog do telefoto – omogućava obuhvaćanje većeg raspona objekata, bez prekida radi zamjene objektiva. Pruža dobre značajke i pri slabom osvjetljenju, a stabilizator slike s kompenzacijom od 4 koraka smanjuje efekt zamućivanja nnebH.
