About the OpticsThe Phase One P45 Plus receives a score of 51 out of 100 in our evaluation. 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 OpticsThe 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. | |

Features14/100 | |
About the FeaturesThe 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 However, the outdated features make it less competitive in today’s market, where cameras with more advanced features are available. | |

Storage & Battery51/100 | |
About the Storage & BatteryThe 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. | |
