The Olympus E420 receives a score of 37/100 in our evaluation. Launched in 2008 at a price of $520, this DSLR camera features dimensions of 130 x 91 x 53mm and weighs 426g (0.94lbs). Although it was a decent option in its release year, the E420 now faces tough competition in today’s market. Its specifications are no longer cutting-edge, making it less attractive to modern photographers. However, the camera still has some merit for those seeking a basic, budget-friendly DSLR.

Olympus E420 Overview and Optics

The Olympus E420 receives a score of 37/100 for its optics. This camera features 10 megapixels, a shooting speed of 3.5, and an NMOS sensor. Equipped with a TruePic III processor and a DXOMARK score of 56 for its sensor, the E420 falls behind in today’s competitive market. The camera has a Micro Four Thirds sensor size and uses a Micro 4/3 lens mount. It lacks image stabilization and has an aspect ratio of 4:3.

Comparing the Olympus E420 to modern cameras, it becomes evident that its optics are outdated. Current models offer higher megapixel counts, faster shooting speeds, and better sensor technology. Additionally, the absence of image stabilization in the E420 is a notable disadvantage. Thus, the Olympus E420’s optics do not hold up well in today’s market.

The higher the number of megapixels, the more detail the cameras sensor can capture.

Image Resolution
Image resolution is measured in pixels and megapixels, width by height. The higher the number, the higher its resolution.
3648 x 2736 px
Sensor Type
The camera sensor captures light and records the image. Sensors vary in physical size, the number of pixels, and quality.
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.

Sensor Format
Refers to the most commonly used sensor sizes.
Micro Four Thirds
Frame Rate
The number of sequential frames per second the camera can write to the memory card when shooting in burst or continuous mode.
3.5 fps
Lens Mount
The lens mount will tell you what type of lens range you can fit onto the camera body. Often the same camera company will have different lens ranges for different cameras.
Micro 4/3
Image Processor
The image processor in the camera converts the information collected on the sensor for digital storage on the memory card.
TruePic III
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.
Minimum ISO (Native)
Refers to the lowest native (or 'base') ISO setting. Lower ISO are less sensitive to light but make a cleaner image.
Maximum ISO (Native)
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.
Minimum 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.
Maximum 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.
Minimum Shutter Speed
The minimum shutter speed will tell you the longest exposure your camera can take without using an external accessory.
60 s
Maximum 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.
1/ 4000 s
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.
In-body Stabilization
In-body Stabilization means the camera has a certain technology embedded that counteracts camera shake.
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.

Olympus E420 Features and Benefits

The Olympus E420 features score is 34/100, which is not particularly high when compared to other cameras in today’s market. The camera has a 2.7-inch screen with a resolution of 230,000 dots. However, it lacks a touchscreen, flip screen, GPS, WIFI, and Bluetooth connectivity.

When considering the competition, the E420’s specifications are not outstanding. Many modern cameras have larger screens with higher resolutions, touch capabilities, and various connectivity options. The absence of these features in the Olympus E420 makes it less versatile and appealing to potential buyers.

The Olympus E420 may not be the best choice for those seeking advanced features and connectivity options. However, it might still be suitable for those who prefer a simple, straightforward camera without the need for additional bells and whistles.

Olympus E420 Storage and Battery

The Olympus E420 receives a storage and battery score of 60/100. It has two memory card slots, accepting Compact Flash (Type I or II) and xD Picture Cards. In today’s market, however, many cameras use more common SD cards, which could be a disadvantage for some users.

The camera’s battery life allows for 500 shots, utilizing a BLS-1 battery type. USB charging is not available, which may be inconvenient for some users who prefer to charge their devices on the go. Comparing to other cameras in the market, the Olympus E420’s battery life and storage options may not be the most competitive.

Taking these factors into account, the Olympus E420’s storage and battery performance are satisfactory, but not outstanding. Potential buyers should consider their specific needs and preferences when evaluating this camera.
