What lenses can I use with my canon T3i?

Lens Compatibility. Like other Canon DSLRs with sub-frame sensors (currently, the Canon Rebel XS, Rebel XSi, Rebel T1i, T2i, T3, EOS 50D, 60D, and EOS 7D), the Canon Rebel T3i will work with pretty much any EF-mount lens ever made, as well as with the special EF-S lenses designed for cameras with APS-C size sensors.

What does the subframe sensor mean on the canon T3i?

The sub-frame sensor on the Canon Rebel T3i means that it has a smaller angle of view (by a factor of 1/1.6) than a full-frame camera with any given lens. While most properly called a crop factor, the 1.6x ratio is more commonly referred to as the focal length multiplier since that's how it works in practice. Helpful?

What is the zoom of the Canon EOS Rebel T3i?

The Canon EOS Rebel T3i is available bundled with the EF-S 18-135mm f/3.5-5.6 IS lens. This lens has a generous (for a kit lens) and versatile optical zoom ratio of 7.5x with a 35mm equivalent range is about 29-216mm, because of the T3i's ~1.6x crop factor.

How accurate is the canon T3i's optical viewfinder?

Canon's EOS Utility software allows correction data for lenses (including models as-yet unreleased) to be uploaded to the Canon T3i. Fair accuracy from the optical viewfinder, excellent accuracy from the LCD in Live View mode. The Canon EOS Rebel T3i's optical viewfinder was a little tight, showing just under 94% coverage.

How does peripheral illumination correction work?

Peripheral Illumination Correction works with over 85 different Canon lens models, in both RAW and JPEG workflows. For JPEG shooting, the correction is made at capture time, while RAW shooters can access the function in Canon's Digital Photo Professional software, although Canon shooters should note that the latter approach offers the highest degree of correction. In-camera correction of JPEGs operates with somewhat reduced strength, especially when shooting at higher ISO sensitivities, given that the correction can make image noise more pronounced. From the factory, the T3i body ships with correction data for about 25 lens models. Canon's EOS Utility software allows correction data for lenses (including models as-yet unreleased) to be uploaded to the Canon T3i.

How soft is the Canon Rebel T3i?

Corner Softness. The Canon Rebel T3i and 18-135mm lens produced some slightly soft corners in a few shots. At full wide-angle, corners on the right side of our test targets were somewhat softer than the center, but the blurring didn't extend very far into the frame. The left side, however, showed slightly less softening in the corners. The center of the image was quite sharp. At full telephoto, all four corners were only slightly soft with the top right being the softest. The image was pretty sharp in the center. Corner sharpness in general was pretty good for the type of lens, and somewhat better than expected compared to far-field (house) results.

How big is the Canon T3i macro lens?

The Canon EOS Rebel T3i's macro performance will of course depend entirely on the lens in use. With the 18-135mm IS lens set to 135mm, the Canon Rebel T3i captured a fairly large (even for an SLR lens) minimum area measuring 3.64 x 2.43 inches (93 x 62 millimeters). Details were somewhat soft in the center of the frame, and softer still in the corners and edges. (Most lenses have some softening in the corners at macro distances.) Some noticeable vignetting (corner shading) was also present. Both the softness and vignetting would likely improve by stopping down a bit more, though. (The above macro shots were taken at f/5.6.) The Canon T3i''s flash throttled down for the macro area very well. There was no detectable shadow from the lens barrel, only the same vignetting as in the non-flash exposure.

What lens does the Rebel T3i use?

The Rebel T3i kit is available with two lens choices. One is an updated variant of a lens first introduced with the Rebel XS, now known as the EF-S 18-55mm f/3.5-5.6 IS II, which also ships with the Rebel T3 and T2i. Compared to the earlier EF-S 18-55mm f/3.5-5.6 IS version, that lens has cosmetic changes and uprated stabilization algorithms said to be good for a four stop improvement, but we believe it to be optically similar to the earlier model. The lens has a 3.1x zoom ratio, and a 35mm equivalent focal range of 29-88mm due to the T3i's 1.6x "focal length crop" (see below). This lens is constructed of 11 elements in 9 groups, and extends during both focus and zoom operation. The EF-S 18-55mm II uses a micro DC motor for autofocus, instead of the ultra-sonic motor found on models with the USM designation, and includes both an AF/MF switch and a Stabilizer On/Off switch on the lens barrel. Other specifications include a 6-bladed (rounded) diaphragm, minimum aperture of f/22-f/32, maximum magnification ration of 0.28x (or 1:3.6), and 58mm filter threads. Dimensions are 84.5mm long with a 68.5mm diameter (3.3 x 2.7 inches), and weight is 200g (7.1 ounces). The lens has a MSRP of US$199.99 if bought separately, but costs significantly less when purchased bundled with the camera. A lens hood and soft case are optional accessories. While we've yet to run this newer version through our testing process over at SLRgear.com, the preceding lens was quite impressive when compared to those bundled with Rebel cameras preceding the XS, yielding improved sharpness and reduced chromatic aberration.

What is the difference between 18-55 and 18-135?

This means that the 18-55mm kit lens for the T3i has a coverage roughly equivalent to that of a 29-88mm lens on a 35mm camera, while the alternate 18-135mm kit lens has a coverage roughly equivalent to a 29-216mm lens on a 35mm camera.

What is the subframe sensor on a Canon Rebel T3i?

The sub-frame sensor on the Canon Rebel T3i means that it has a smaller angle of view (by a factor of 1/1.6) than a full-frame camera with any given lens. While most properly called a "crop factor," the 1.6x ratio is more commonly referred to as the "focal length multiplier" since that's how it works in practice.

How much distortion does a Canon 18-135mm have?

The Canon EF-S 18-135mm IS lens produced images with about 1.1 percent barrel distortion at wide-angle, which is higher than average and noticeable in some shots. At the telephoto end, there was about 0.4% pincushion distortion, which is also higher than average though not quite as noticeable.

Is the Canon 60D overpriced?

If you didn't think the 60D was overpriced when it shipped, you will now. The Canon EOS Rebel T3i (aka the EOS 600D), the 60D's younger and cheaper sibling, offers the same basic camera with some corners cut--most notably a slightly less well-constructed body and a (purposely?) stunted burst shooting speed.

Is 400 ISO good for a T3i?

The T3i fared pretty well under these conditions. Overall, I consider shots at this setting good enough to use, but I still wish I would have been able to shoot raw to clean them up.

Is the T3i the same as the T2i?

With a few exceptions, the T3i's body and interface are almost identical to the T2i's. It's slightly heavier (but not larger) thanks to the bright, flip-and-twist LCD. It feels sturdy, and though the texture rubberized grip feels kind of cheap, the camera is comfortable to hold and shoot single-handed, and can stand up to the weight of a good lens. I've never been a huge fan of the Rebel series' viewfinder, and this one is actually a slightly lower magnification than previous models. I don't know that I noticed the difference, but there are better ones out there. Also, I don't like the tiny, too-briefly-flashing AF points.

What Wide Angle Lens for Canon T3i?

Those who want to add a Canon Rebel T3i wide angle lens to their photography gear kit can consider the Canon EF-S 10-18mm f/4.5-5.6 IS STM. This model attracted lots of photographers since it is the first wide-angle lens that combines exceptional image quality, first-class optical performance, and affordability. The EF-S 10-18mm f/4.5-5.6 has an ultra-wide angle of view, which isn't inferior to more expensive models. It features large-diameter aspherical lens elements in 4 groups and UD lens elements to produce high-resolution images with boosted contrast and reduced glare and aberration. Also, the Canon EF-S 10-18mm f/4.5-5.6 has a circular aperture with seven blades to create beautifully blurred backgrounds and highlight the subject.

What is the difference between Canon Rebel T3i and USM?

Canon Rebel T3i compatible lenses differ depending on the motors used. USM and STM are the most typical types of motors. The models created based on the USM technology boast the ideal combination of speed and durability. That is why many photographers choose them for shooting fast-paced sports, action, and outdoor photos. Even though STM lenses work slower than USM ones, they ensure smoother and more silent operation. Such lenses are suitable for common photography ventures and shooting crisp footage.

What is a Canon T3i?

Canon T3i is a DSLR camera suitable for entry-level photographers. Compared to its predecessor, T2i/550D, it is considerably improved with new features.

What is a Canon 75-300mm?

The Canon EF 75-300mm is a compact and lightweight 4x telephoto zoom. The combination of broad focal length coverage and silent autofocus motor makes it a perfect option for taking portraits or documenting sports events.

Why do we use nano coating?

Multi-layer Nano coating is applied to some lens elements to prevent surface reflection and reduce lens flare and ghosting. This allows you to take spectacular images with enhanced contrast, even if you shoot in a bright and backlit environment.

How many stops does a lens have?

The majority of lenses with image stabilization can give you 2-4 stops (exposures 4–16 times longer), which allows avoiding blurry photos. Lens-based optical stabilization will come especially in handy if you zoom in subjects when shooting in poorly-lit conditions.

What is the aperture of a lens?

The aperture of a lens defines the amount of light that can be transmitted to the image sensor. The larger the aperture opening is, the lower f-number the lens has. If you want to get right in action photography and capture fast-paced scenes without blur, it is better to use the lens with a wide aperture since it allows you to use a higher shutter speed.
