Pentax 645D Review | 108 Data compared

The ePHOTOzine review of the Pentax 645D identifies it as a portable, ruggedly built 40-megapixel medium-format DSLR suitable for professionals, featuring excellent ergonomics and a robust, weather-sealed magnesium alloy chassis. It excels in landscape photography, offering a large glass viewfinder and a supersonic dust removal system, while supporting legacy 645 film lenses. Pros include superior handling, a competitive price point relative to rivals, and excellent image quality. However, constraints include a limited native ISO range of 200–1000 and a noticeably thick, bulky body compared to standard DSLRs.

The Trusted Reviews analysis of the 40-megapixel Pentax 645D positions it as a robust, weather-sealed field camera designed for landscape photography, featuring a durable magnesium alloy chassis and a comfortable, ergonomic design. Key advantages include its 98% viewfinder, a clear 3-inch LCD, a native vertical/horizontal tripod mounting system, and 77-segment metering that preserves highlights. Conversely, the review notes significant limitations, such as slow, 1.1fps continuous shooting and sluggish write times that take up to 11 seconds for RAW+JPEG files. Further cons include an autofocus system that struggles in low light and a complete lack of tethered shooting capability for studio workflows.

The What Digital Camera review identifies the Pentax 645D as a rugged, weather-sealed medium format camera designed for field use, offering an intuitive handling experience similar to the Pentax K-7 DSLR. Key pros include a high-resolution 40-megapixel sensor delivering exceptional image quality, excellent ergonomics for DSLR users, and a large, clear viewfinder. Conversely, the review notes drawbacks, including sluggish image write speeds to the SD cards, a viewfinder with only 98% field of view coverage, and limited flash sync speeds. Additionally, the camera lacks out-of-the-box tethered shooting and is positioned at a high price point, rendering it more suitable for dedicated landscape professionals than general users.

Ashwin Rao’s review details his transition from a Leica rangefinder to digital medium format landscape photography after discovering a pristine, used Pentax 645D at Glazer's Camera in Seattle. Intrigued by the prospect of affordable medium format entry, he traded his Pentax K5 kit to acquire the system, specifically using it during a 24-hour photographic expedition to the rolling, pastoral sand dunes of the Palouse region in Eastern Washington. Rao underscores that heritage, manually focused, and autofocus Pentax 645 lenses—acquired for under $3,000 USD total—performed exceptionally well on the camera's 40-megapixel, 44 x 33 mm Kodak CCD sensor, which lacks an anti-aliasing filter. Despite industry buzz surrounding the highly resolving 36-megapixel Nikon D800/E at the time, Rao chose the Pentax 645D for its unique medium-format rendering, shallower depth of field, and significantly lower heritage lens costs compared to high-end Nikon or Zeiss glass. The review highlights several distinct pros and cons of operating the Pentax 645D system. On the positive side, the camera boasts massive sensor real estate capable of rendering immense detail, a highly intuitive SLR-like user interface with a...

The Pentax 645D is a unique, professional-grade medium-format SLR camera that offers an outstanding handling experience tailored for landscape and portrait photographers, rather than action or sports. The reviewer praises its exceptionally deep, comfortable grip and an intuitive layout packed with dedicated physical controls—such as a dedicated mirror lock knob—which saves valuable time otherwise spent digging through menus. Additionally, it features an enormous, well-lit viewfinder that dwarfs standard DSLR viewfinders and accommodates a highly customizable, comprehensive menu system. Despite its bulky appearance, the camera body is surprisingly manageable in weight, scaling similarly to professional flagship DSLRs. The core selling point of the camera is its massive 44 x 33mm sensor, which completely lacks an anti-aliasing filter to produce exquisite, unmatched image sharpness and micro-details at lower ISO settings. However, this emphasis on image resolution highlights several key performance limitations. On the negative side, the camera is restricted to a very slow continuous shooting speed of just 1 frame per second, its high-ISO performance is below average, and the autofocus system functions adequately but quite slowly. The menu interface, while highly...

The Pentax 645D is highlighted as a practical, highly capable entry point into digital medium format photography, serving effectively as a digital counterpart to the vintage 645N film camera. Built with a 40-megapixel Kodak CCD sensor, the camera delivers a distinct "medium format look" characterized by film-like color rendering, deep gradations, and impressive subject isolation at a distance. It functions seamlessly as a modern walkabout device by offering familiar DSLR ergonomics, excellent battery compatibility across the Pentax line, dual SD card slots, and an accurate 11-point phase-detect autofocus system. Furthermore, its native compatibility with affordable, legacy film-era lenses and full integration with modern Godox/Flashpoint TTL flash systems make it an exceptionally high-value package for stills-focused photographers. However, embracing this vintage digital setup requires accepting several distinct technological sacrifices inherited from its older CCD architecture. The camera is limited to a slow continuous shooting speed of just 1 frame per second and suffers from humorously long memory card write speeds. It completely lacks modern conveniences such as video recording and Live View capabilities, meaning photographers must rely entirely on the optical...

In his review on 35mmc, Eric L. Woods highlights the Pentax 645N (analog) and Pentax 645D (digital) as complementary medium format cameras rather than competitors. The core strength of this system is Pentax's dedication to lens mount compatibility, allowing older manual and autofocus film lenses to be used seamlessly across both bodies. The pros of both cameras include their excellent, sturdily built DSLR-like ergonomics, highly accurate TTL flash automation, and dual tripod mount points for seamless portrait shooting. Furthermore, the system offers exceptional value on the used market, where high-quality legacy lenses are highly abundant and much more affordable than modern digital medium format glass. However, the reviewer notes several distinct cons and trade-offs between the two bodies. The Pentax 645D suffers from slow memory card writing speeds, and its older CCD sensor means you completely lose modern features like Live View, video capabilities, and an articulating screen. Additionally, its 40MP sensor has a 0.79× crop factor, making it smaller than the 0.62× crop of true 645 film. Control layouts also diverge; the 645N relies on analog shutter speed and...

The Digital Journal of Photography review highlights the Pentax 645D as a durable, magnesium-alloy medium format camera offering an intuitive, DSLR-like interface for improved usability. It is highly praised for features like its 921k-pixel rear screen and the inclusion of a sensor-vibration cleaning system. digitaljournalofphotography.com Conversely, the review criticizes the reliance on slow dual SD slots for large raw files and an 11-point autofocus system with points concentrated solely in the center. Additional drawbacks include potential image softening from shutter vibrations and a fixed body design that limits modular flexibility.
