Rebel Xti Eos Lenses: Compatible Cameras For You

The Canon EOS Rebel XTi is a camera model that is compatible with a variety of lenses. It is important to understand lens compatibility with your camera to elevate your photography experience. The Canon EOS Rebel XTi is compatible with EF-mount lenses and EF-S lenses designed for cameras with APS-C size sensors. The EF-S lenses are smaller and lighter than full-frame models with similar specifications. The Canon EOS Rebel XTi also has a sub-frame sensor, which means it has a smaller angle of view than a full-frame camera with any given lens. This is also referred to as the focal length multiplier.

Canon EOS Rebel XTi compatible lenses

The Canon EOS Rebel XTi is a digital, single-lens reflex camera that is compatible with a variety of lenses. It uses the EF and EF-S lens mount, which means that it is compatible with Canon EF and EF-S lenses. This includes lenses with image stabilisation, tilt-shift lenses, and lenses with a maximum aperture of f/2.8.

The Rebel XTi is compatible with a range of wide-angle, telephoto, and macro lenses, as well as superzoom and super telephoto lenses. Some specific lenses that are compatible with the Rebel XTi include:

• Canon EF-S 18-55mm f/3.5-5.6 II
• Canon EF 50mm f/1.8 STM
• Canon EF 70-210mm f/4
• Canon EF 85mm f/1.8 USM

It's important to note that while some older EF and EF-S lenses can be physically adapted to fit the Rebel XTi, they may not have full compatibility with the camera's features, particularly autofocus performance. Lenses manufactured before 2008 may not support DPAF (Dual Pixel Autofocus) and may have slower autofocus motors.

Additionally, third-party lenses adapted to the Rebel XTi may have hit-or-miss compatibility. For the best experience and full feature compatibility, it is recommended to use lenses released in 2009 or newer.

Canon EF mount lenses

The Canon EOS system has a wide range of compatible lenses, with over 200 EF lenses available. The EF lens mount was introduced in 1987 with the launch of the EOS system, and it remains the standard lens mount for Canon EOS cameras. EF stands for "Electro-Focus", with automatic focusing on EF lenses handled by an electric motor built into the lens. The EF mount is a bayonet-style mount, and all communication between the camera and lens takes place through electrical contacts.

EF-mount lenses are somewhat compatible with newer Canon bodies, but not the other way around. Here is a list of compatible camera bodies and whether they require an adapter:

• EF-S lens mount cameras: These can mount EF lenses without an adapter.
• EF-M lens mount cameras: These can mount EF lenses with an EF-EOS M adapter.
• RF lens mount cameras: These can mount EF lenses with a variety of adapters.

Canon also offers an accessory for mounting EF lenses to R series bodies, but this may not result in full functionality.

Third-party manufacturers also produce compatible lenses with the EF lens mount, including Yongnuo, Samyang, Schneider, Sigma, Tamron, Tokina, Cosina, and Carl Zeiss. However, these lenses are not supported by Canon, and sometimes compatibility issues arise.

Canon EF-S mount lenses

The Canon EF-S lens mount is used for Canon digital single-lens reflex cameras with APS-C-sized image sensors. The EF-S mount is a derivative of the EF lens mount and was released in 2003. Cameras with the EF-S mount are backward compatible with EF lenses and have a flange focal distance of 44.0 mm.

The "S" in EF-S stands for "Small image circle" or "Short back focus". The small image circle refers to the lens projecting a smaller image circle than normal EF lenses to match the sensor. The short back focus refers to the smaller mirror used in APS-C cameras, which allows optical elements to protrude further into the camera body, reducing the minimum distance between the sensor and the back element of the lens.

The combination of a smaller sensor and shorter back focal length distance enhances the possibilities for wide-angle and very wide-angle lenses. Such lenses designed for the EF-S mount can be made smaller, lighter (as they contain less glass), faster (larger aperture), and less expensive.

Cameras that can use the EF-S mount include:

• EOS 300D/Digital Rebel
• EOS 350D/Digital Rebel XT
• EOS 400D/Digital Rebel XTi
• EOS 4000D/Rebel T100
• Blackmagic Pocket Cinema Camera 6K
• Blackmagic Studio Camera 6K Pro

EF-S lenses are designed solely for use on Canon APS-C DSLRs. Canon EF lenses, on the other hand, are designed to work with both full-frame and APS-C DSLRs from Canon. EF-S lenses have a smaller image circle, which is only large enough to cover the smaller sensor found on Canon APS-C cameras. If an EF-S lens is used on a full-frame DSLR, heavy vignetting will occur (the corners of the image will be black) because the image circle produced by the lens is too small to cover the larger sensor.

EF-S lenses are generally smaller and lighter than EF lenses, and they are also more affordable. Canon does not produce "professional" EF-S lenses like the "pro" "L" lenses found on the EF mount. Canon uses lower-grade materials for its EF-S line of lenses while still producing solid results.

Canon EOS R100 compatibility

The Canon EOS R100 is a lightweight, compact, and easy-to-carry camera. It is compatible with Canon's RF and RF-S lenses, and the kit lens is RF-S 18-45mm. The camera features a 24.1-megapixel APS-C CMOS sensor, a DIGIC 8 processor, and Dual Pixel CMOS AF with human and animal eye-detect AF. It can record Full HD video at up to 60 frames per second and 4K video at 24 frames per second.

The EOS R100 is not directly compatible with EF or EF-S mount lenses, which were used on previous Canon cameras like the Rebel XTi. However, these lenses can be adapted to the EOS R100 using a third-party or Canon's EF-RF mount adapter. It is important to note that older EF and EF-S lenses may not have full compatibility with the EOS R100, as they lack the necessary hardware for certain features, such as Dual Pixel Autofocus (DPAF).

Overall, the Canon EOS R100 is a versatile and affordable camera that is suitable for beginners and experienced photographers alike. It offers good image and video quality, a range of compatible lenses, and a compact form factor, making it a great option for travel and everyday photography.

Canon EOS R series compatibility

The Canon EOS R Series of cameras is compatible with Canon RF Series lenses. However, Canon EF and EF-S Series lenses can also be used with the EOS R Series by utilising one of the optional Canon EF-EOS R Mount Adapters. It is important to note that the EF-EOS R Mount Adapters are not compatible with Canon EF-M Series lenses.

While it is possible to adapt EOS Rebel XTi lenses to the EOS R100 via an EF-RF Mount adapter, it is not recommended as these older lenses may not function properly with the R series body. Lenses manufactured before 2008 do not support DPAF and have slower motors, which may hinder the performance of your camera.

The Canon EF-EOS R Mount Adapters come in three varieties: the Mount Adapter EF-EOS R, the Control Ring Mount Adapter EF-EOS R, and the Drop-In Filter Mount Adapter EF-EOS R. The Control Ring Mount Adapter EF-EOS R adds a customisable control ring, similar to those found on RF lenses, allowing for easy adjustment of settings such as ISO and aperture. The Drop-In Filter Mount Adapter EF-EOS R includes drop-in filter capability for use with circular polarising filters or variable ND filters.

The Canon EOS R Series is designed to be future-proof and backward compatible, offering a versatile system that can accommodate both new and old lenses.
