Is 18 135mm a good lens?

Is 18 135mm a good lens?

The EF-S 18-135mm f/3.5-5.6 IS USM Lens is attractive on many fronts, including its wide (7.5x) focal length range, its relatively small size and light weight, its fast, smooth and accurate autofocusing, its great functionality including image stabilization and its modest price.

What does EF stand for Canon?

A lens mount is the standard or pattern that is used to connect the lens to the camera. Canon uses a standard lens mount called EF. EF lenses were introduced in 1987 for Canon SLR cameras, and EF stands for “Electro-Focus” because it has a built-in motor in the lens for automatic focusing.

WHAT IS STM?

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 the i stand for in Canon cameras?

More recently, Canon described the letters EOS as meaning 'Electro-Optical System', of which they have copy-write. Canon first made reference to the term EOS in the late 1980's when they produced their first auto focus SLR camera.

What does Canon EOS mean?

Canon EOS (Electro-Optical System) is an autofocus single-lens reflex camera (SLR) and mirrorless camera series produced by Canon Inc. Introduced in 1987 with the Canon EOS 650, all EOS cameras used 35 mm film until October 1996 when the EOS IX was released using the new and short-lived APS film.

Do all Canon lenses fit all Canon bodies?

Much older lenses didn't have internal electronics & used another mount. No, crop sensor cameras (all Rebel cameras, 40/50/60D, and the 7D) can take EF or EF-S lenses. Full frame cameras (all 1D, 5D and 6D) only take EF lenses. The mirrorless camera (EOS-M) use EF-M lenses, but can use EF and EF-S with an adapter.

What are telephoto lenses good for?

Telephoto Lenses. A telephoto lens is one designed for photographing distant subjects like wildlife and sports events. They are also used in portrait photography. A telephoto lens is a type of camera lens designed for taking photographs of subjects at moderate to far distances.

What does the red ring on Canon lenses mean?

Red. 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 crème de la crème 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.

What is the difference between Canon EF and EF S lenses?

Put simply, Canon EF-S lenses are designed solely for use on Canon APS-C DSLRs. Canon EF lenses are designed to work with full frame and APS-C DSLRs from Canon. Canon EF-S lenses have a smaller image circle that is only big enough to cover the smaller sensor found on Canon APS-C cameras.

What is a prime lens in photography?

In film and photography, a prime lens is a fixed focal length photographic lens (as opposed to a zoom lens), typically with a maximum aperture from f2.8 to f1.2.

Why are Canon lenses white?

A number of Canon's professional L series lenses — all super-telephoto lenses — are “white” with the distinctive red ring. … “But large lenses contain large elements and here expansion can bring a lens close to the limits of its design tolerances. A white surface reflects sunlight, helping to keep the lens cooler.”

What is Nano USM lens?

The new lens is the first Canon lens that features a new type of focusing motor called Nano USM. Nano USM lenses use a motor system that combines the benefits of a ring ultrasonic motor (USM) with a lead-screw type STM (stepping motor).

Is Canon 18 135 A wide angle lens?

Compact wide-to-tele zoom is designed for APS-C-format Canon EF-S-mount DSLRs, and offers a 28.8-216mm equivalent focal length range. One ultra-low dispersion element reduces color fringing and chromatic aberrations for high clarity and color fidelity.

What does F 4l mean?

Yes. The f4 is the smallest f number (largest aperture). In general f2.8 is "better" than the f4 though it all depends on the lens. The f2.8 lenses tend to be heavier and bulkier than their f4 counterparts. The 24-105/4L IS is the only full frame standard L zoom with IS.

Can you use an EF lens on an EFS camera?

The short answer to your question is yes, an EF lens can be used on a crop-sensor (EF-S) Canon camera. … Some of the EF-S lenses protrude into the body and so for full frame cameras that would cause the mirror to come into contact and get damaged, but even if they do not, they can't be used.

What do numbers on a lens mean?

Focal length is expressed in mm and a higher number means a bigger zoom, while a lower number mean the lens can be used for wider shots. … If the lens has a focal length range with two numbers (say 24-80 mm) this means it's a zoom lens and is capable of zooming and being used at any point across that range.

What are the different Canon lens mounts?

There are three distinct families of Canon lenses. They include the EF mount, for use with Canon's full-frame (24 x 36mm) and APS-C (22.3 x 14.9mm) format DSLRs, the EF-S mount for use exclusively with Canon's APS-C format DSLRs, and the EF-M mount, designed for use exclusively with Canon EOS M mirrorless cameras.

What does USM mean in text?

USM. Unstoppable Sex Machine (band) USM.

What does ultrasonic focus mean?

An ultrasonic focus motor is much quieter (almost near-silent) and also moves the focus lens or ring faster when compared to a standard motor. A USM is able to hold the lens in place with precision and accuracy at the exact instant the lens arrives at the correct focus when using the camera's auto focus (AF) feature.

What do the numbers on a Canon lens mean?

The first number or pair of numbers indicates the range of available focal lengths in millimeters. From this you can tell what angles of view the particular lens can handle. Lower numbers mean a wider angle. So an ordinary, basic 18-55 DSLR lens can “zoom” from medium-wide views out to the beginning of telephoto range.

What does mirrorless camera mean?

A digital camera that accepts different lenses. Also called a "mirrorless interchangeable-lens camera" (MILC), "hybrid camera" and "compact system camera" (CSC), the body is thinner than a digital SLR (DSLR) because it does not use a mechanical mirror to switch the scene between the optical viewfinder and image sensor.

How do ultrasonic motors work?

The modification amplifies and spreads with stator metal, and generates a traveling wave on the surface of stator metal. Here, the stator metal touches the rotor only at each peak of a traveling wave, and each of that peak carries out elliptical movement.
