About This CameraThe EOS Rebel T100, sold as the 4000D in some regions, is a straightforward beginner DSLR from 2018. It combines an 18-megapixel APS-C sensor with the EF-S mount and an optical viewfinder, the classic DSLR layout for learning the craft. Its pace suits unhurried photography: portraits, landscapes, travel snaps and family records. Anyone chasing sports or fast-moving wildlife will find little margin here, because the camera shoots at up to 3 fps and autofocus uses nine points, favouring subjects that hold still. Carrying it is easy at 475 g, and built-in WiFi plus Bluetooth give it wireless connectivity. There is no weather sealing, so it needs shelter in rain and dust. | |

About the OpticsThe 18-megapixel APS-C CMOS sensor, paired with the Digic 4+ processor, gives enough resolution for prints and web use, though the figure is modest. The Optics score of 39 reflects a limited specification overall. Continuous shooting reaches 3 fps and autofocus uses nine points, so the camera rewards deliberate framing. Portraits, landscapes and static scenes work well; fast sports or erratic wildlife will test its pace. The ISO range of 100 to 6400 and a top shutter speed of 1/4000 second provide standard exposure control, but dim conditions push you toward that ceiling quickly. There is no in-body stabilisation, so at slower shutter speeds you will want steady support or a faster lens. Framing through the optical pentamirror viewfinder is immediate, and the EF-S mount accepts Canon's DSLR lenses. Overall it sits in the bottom 4% of cameras in our database for Optics, which fits its role as a basic model. | |
Megapixels ⓘThe higher the number of megapixels, the more detail the cameras sensor can capture. | 18 MP050 |
Image resolution ⓘImage resolution is measured in pixels and megapixels, width by height. The higher the number, the higher its resolution. | 5184 x 3456 |
Sensor type ⓘThe camera sensor captures light and records the image. Sensors vary in physical size, the number of pixels, and quality. | CMOS |
Sensor size ⓘThe sensor size contributes to the overall quality as well as the dynamic and tonal range a camera can capture. As a rule of thumb, the more surface there is to read the light, the more information it will capture. | 14.9 x 22.3 |

Image processor ⓘThe image processor in the camera converts the information collected on the sensor for digital storage on the memory card. | Digic 4+ |
Aspect ratio ⓘThe aspect ratio refers to the proportional difference between width and height. The most popular aspect ratios are 3:2 and 4:3. | |
Min ISO ⓘRefers to the lowest native (or 'base') ISO setting. Lower ISO are less sensitive to light but make a cleaner image. | 10030200 |
Max ISO ⓘRefers to the highest native (or 'base') ISO setting. Higher ISO is necessary for low-light situations or night photography, but higher ISOs often introduce grain or noise. | 64003003280000 |
Min ISO (expanded) ⓘExpanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary. | 10030200 |
Max ISO (expanded) ⓘExpanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary. | 128003003280000 |
Minimum shutter speed ⓘThe minimum shutter speed will tell you the longest exposure your camera can take without using an external accessory. | 3044080 |
Max shutter speed ⓘThe maximum shutter speed tells you the length inside 1 second the camera will capture. These can sometimes be extended with accessories such as extra external batteries. | 400080032000 |
Autofocus points ⓘAutofocus points show where the camera is focusing graphically as squares or brackets in Live View or on an electronic viewfinder. These points are also used for light meter readings. | 90300 |
In-body stabilisation ⓘIn-body Stabilization means the camera has a certain technology embedded that counteracts camera shake. | No |
Viewfinder type ⓘThe viewfinder type is either electronic or optical. Electronic viewfinders will have a small screen in the viewfinder. Optical viewfinders will use prisms and mirrors to look through the lens. | Optical (pentamirror) |

Video43/100 | |
About the VideoRecording tops out at Full HD resolution, with frame rates reaching 30 fps, and clips save as MOV files. This covers casual family movies, simple online videos and learning projects, where the aim is usable footage rather than production polish. The modest Video score of 43 reflects this basic capability set. Full HD output looks fine on phones and computers, but anyone wanting 4K detail or slow-motion footage will not find it here. There is no built-in timelapse function, so interval projects need an external timer or the manual effort of shooting frame by frame and assembling the results afterwards. Clips save as MOV files on the same SD, SDHC or SDXC cards used for stills, so one card carries everything from a shoot. | |
Video ⓘIndicates if this camera is capable of recording video. | |
Max video resolution ⓘThe best resolution this camera can capture video in. Modern cameras can capture up to 8K video. | |
Max video format ⓘVideo resolution measured by the greatest number of pixels possible in each frame, width by height. A higher resolution means more detail or clarity in your video. | 1920 x 1080 |
Max video frame rate ⓘHow many frames per second your video will capture. Most cameras have options for multiple frame rates, depending on the resolution you shoot in. For a general video, 24p or 30p is the standard, but more serious filmmakers may need a higher frame rate for creative effect. | 30 fps |
Timelapse built in ⓘA built in time-lapse mode will allow continuous shooting throughout a prolonged period of time to be compressed into a sped up video. | No |
Video file format ⓘDifferent cameras can record in various video file formats. The File format you record in can impact how you edit and use the files. | MOV |
Features47/100 | |
About the FeaturesThe 2.7-inch LCD is small, fixed in place and not touch-sensitive. Its 230,000 dots make checking fine focus less precise than on sharper screens, and live view, while available, is the only alternative to the optical viewfinder. Wireless connectivity is the bright spot, with both WiFi and Bluetooth built in. Neither GPS nor weather sealing is present, so the camera records no location data by itself and needs shelter from rain and dust. A built-in flash handles dim indoor snapshots, and support for an external flash adds a stronger light when you need one. The Features score of 47 is modest, reflecting the small fixed screen, its low dot count and the absence of touch control and weather sealing. | |
Builtin flash ⓘA built-in flash will often be positioned right above the lens. This will automatically pop up when you activate it. | |
External flash ⓘExternal flashes are often connected through a hot shoe at the top of a camera, or a cable at the side of the camera. | |
GPS ⓘGPS features in a camera will include location metadata to each of your photographs. | No |
Weather sealing ⓘWeather sealing capabilities will give you more confidence when shooting in unfavourable conditions. | No |
| Screen type | LCD |
Touch screen ⓘTouchscreen allows you to change camera settings and access menus with a swipe of your finger, instead of using buttons. | No |

Storage & Battery27/100 | |
About the Storage & BatteryImages record to a single SD, SDHC or SDXC card. With one slot there is no in-camera backup, so a failed card takes the whole shoot with it, and carrying a spare card is wise. The LP-E10 battery carries a rating of 500 shots per charge. How long that lasts in practice depends on shooting habits, so the figure is a guide rather than a guarantee. There is no USB charging, so the camera cannot top its battery up from a laptop or power bank over USB. Instead you rely on charged spares, which makes a second LP-E10 sensible for longer outings. The limited Storage and Battery score of 27 reflects the single card slot, the 500-shot rating and the absence of USB charging. | |
