IS stands for Image Stabilisation i.e. you get a sharper more clearer photograph while handling your camera without an external stabilizer such as tripods. Lenses which come with this feature are very handy but are not quite silent in their focussing and shot snapping. STM is an abbreviation for Stepping Motor.
Which lens IS better IS or STM?
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 and STM lens?
Popular STM lenses:
Canon EF 50mm f/1.8 STM.Canon EF-S 18-135mm f/2.8 f/2.8 Macro IS STM. Canon EF-S 10-18mm f/4.5-5.6 IS STM. Canon EF 40mm f/2.8 STM.
IS STM and IS ii difference?
STM is the new version of 18-55mm which stands for “STepper Motor” technology for focusing, which is more silent compared to previous IS & IS II versions, and this helps while shooting videos, it won’t have focusing sound. The STM lens has a metal mount, and other versions have plastic mount.
What IS a STM lens used for?
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.
What does EF stand for Canon?
Electro-Focus
The EF lens mount is the standard lens mount on the Canon EOS family of SLR film and digital cameras. EF stands for “Electro-Focus“: automatic focusing on EF lenses is handled by a dedicated electric motor built into the lens.
What is a Canon is lens?
IS stands for Image Stabilizer. A lens with IS in its title has some form of image stabilisation built into it. Canon lenses do not offer image stabilisation for images as standard in their bodies although they are starting to offer digital image stabilisation for video so this is a desirable feature.
What is EF-S camera?
EF-S stands for Electro-focus short back focus. This Canon lens mount was launched alongside the EOS 300D (EOS digital Rebel) camera in 2003. EF-S lenses have an image circle which just covers the sensor of APS-C cameras, meaning that the image circle is smaller in size than in EF lenses.
What are EF and RF lenses?
RF mount lenses employ a 12-pin connection between the camera and lens for comparison, the EF-mount uses 8 pins.Faster data transfer, which means lightning-fast autofocus, enhanced image stabilisation thanks to better communication between the camera and lens, and also provides general optimisation of image quality.
What do you use a 50mm lens for?
50mm lenses are fast lenses with a fast maximum aperture. The most basic 50mm lenses are typically F1. 8 – a very wide aperture. This means they are great for low-light photography (e.g. low-light portraiture or indoor shooting) as they allow more light into the camera’s sensor.
Is II a lens?
The EF-S 18-55mm f/3.5-5.6 IS II is a high-quality, standard zoom lens that will appeal to photographers who prefer to travel light. With a focal length equivalent of 29-88mm in 35mm format, the lens’ wide zoom range is suitable for most general photography.
Is 55 250mm a good lens?
The Canon 55-250mm IS II is optically superb and handles very well for a mostly plastic lens. The biggest negative is that the focus ring and filter thread rotate during autofocus. It’s a kit lens sold with many less expensive Canons, and it’s excellent.
| On APS-C at 10′ (3m) | Correction factor |

| 250mm | -1.0 |
What is a HSM lens?
For those unfamiliar with the numerous lens acronyms, HSM stands for Hyper Sonic Motor, (also known as Ultrasonic motor, Silent Wave Motor or even Sonic Direct-drive Motor) and is a faster, quieter and often more compact motor system for lenses. Essentially this should mean quieter and faster focusing.
What is a DC lens?
“DC” stands for Defocus Control. DC allows the photographer to change the distortion characteristics of the lens so the “look” of the out-of-focus elements in the foreground or background can be changed to produce more pleasing photos, particularly portraits.
Why are USM lenses more expensive?
USM signifies the lens has an UltraSonic Motor for autofocus. That means AF is faster and quieter then the less expensive lens, which uses a conventional motor.The more expensive lens is 0.5 stops faster at 17mm (f/2.8 vs f/3.5) and a full 2 stops faster at 55mm (f/2.8 vs. f/5.6).
What is an 18 55mm lens good for?
The best thing about the 18-55mm lens is its versatility. At 18mm, it is fairly wide-angled and is great for landscapes. In the middle of its range, around 35mm, it is perfect for street, travel, and documentary photography, while the short telephoto zoom of 55mm works wonders for portraits.
What does RF mount stand for?
2018: RF Mount (R Focus) was introduced with the EOS R, Canon’s first MILC (Mirrorless Inter-Changeable Lens) Camera.
Is Canon EF dead?
Over the past two years, we’ve been focused on building out our range of RF lenses to expand the creative possibilities of our R-System consumers, however, our commitment to supporting our EF lens range is unwavering. It’s true, Canon has recently discontinued select EF lenses in our range.
Why do some Canon lenses have a red ring?
If the lens has a red line, the lens is part of Canon’s L series. The L stands for luxury and these are the cr?me de la cr?me of Canon lenses. L series lenses feature top of the line optics and build quality making the most coveted and expensive of the Canon lenses.
Can any lens fit on Canon?
APS-C cameras, which are the bulk of the DSLRs that Canon offers, can use virtually all modern lenses: both EF and EF-S. Meanwhile, full frame and APS-H size sensor cameras are a bit more limited, to EF lenses only. There are also many third party lenses made in the EF mount.
WHAT is STM on Canon lens?
STM Stepper Motor designed to minimize autofocus vibrations and noise during video recording, this autofocus motor has been gradually making its way into budget Canon lenses.
