The Phase One P45 Plus receives a score of 51 out of 100 in our evaluation. This medium format camera, announced on January 1, 2007, and released the same year, originally cost $32,990. Measuring 156 x 128 x 184mm and weighing 1800g, or 3.97lbs, the P45 Plus is a substantial camera. However, considering the advancements in technology since 2007, this camera’s specifications are now less competitive in today’s market.

Phase One P45 Plus Overview and Optics

The Phase One P45 Plus receives an optics score of 66/100. With 39 megapixels and a shooting speed of 0.67 frames per second, this camera has a CCD sensor and a Phase-One processor. The DXOMARK score for the sensor is 77, and it features a medium format sensor size. The lens mount used is Mamiya 645 AF, but it lacks image stabilization. The aspect ratio is 4:3.

In today’s market, the Phase One P45 Plus has decent specifications. However, it faces competition from cameras with better optics and image stabilization. The medium format sensor size is still relevant, but the shooting speed of 0.67 frames per second is slow compared to modern cameras. The lack of image stabilization is a drawback for photographers who require steady shots.

The Phase One P45 Plus has adequate optics for specific photography needs but does not excel in all aspects. It may not be the best choice for photographers seeking top-of-the-line optics and image stabilization.

The higher the number of megapixels, the more detail the cameras sensor can capture.
39 MP
Image Resolution
Image resolution is measured in pixels and megapixels, width by height. The higher the number, the higher its resolution.
7246 x 5444 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.
37 x 49 mm
Sensor Format
Refers to the most commonly used sensor sizes.
Medium Format
Frame Rate
The number of sequential frames per second the camera can write to the memory card when shooting in burst or continuous mode.
0.67 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.
Mamiya 645 AF
Image Processor
The image processor in the camera converts the information collected on the sensor for digital storage on the memory card.
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.
3600 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/ 10000 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.

Phase One P45 Plus Features and Benefits

The Phase One P45 Plus achieves a feature score of 14/100. Its specifications include a screen size of 2.2 inches, screen resolution of 230400 dots, and the absence of a touchscreen, flip screen, GPS, and Bluetooth. The camera only comes with WIFI connectivity.

Comparing these features to current market standards, the P45 Plus falls behind in several aspects. A 2.2-inch screen is smaller than most modern cameras, and the lack of touchscreen and flip screen functionality limits user experience. The absence of GPS and Bluetooth further reduces its compatibility with contemporary devices and applications.

Despite its lower feature score, the Phase One P45 Plus still has some redeeming qualities, such as its image quality and optics. However, the outdated features make it less competitive in today’s market, where cameras with more advanced features are available.

Built-in Flash

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 features in a camera will include location metadata to each of your photographs.
Weather Sealing
Weather sealing capabilities will give you more confidence when shooting in unfavourable conditions.
Screen Type
Touch Screen

Phase One P45 Plus Storage and Battery

The Phase One P45 Plus receives a storage and battery score of 51/100. This camera has one memory card slot, accepting Compact Flash cards. Although Compact Flash cards provide sufficient storage capacity, they are not as common as SD cards in the current market, which may be a drawback for some users.

The P45 Plus is equipped with a BP-915 battery, allowing for 2500 shots per charge. This battery life is impressive and surpasses many competitors in the market. However, the camera lacks USB charging capabilities, which could be inconvenient for on-the-go photographers.

Considering the storage and battery specifications, the Phase One P45 Plus offers a reliable battery life but falls short in terms of storage flexibility and charging options.
