Conclusion: It is cheaper than the medium format competition, but perhaps still not quite within easy grasp of the average pro photographer. On the other hand, if only medium format will do and you can stretch your budget, it's the best value package around.
Excerpt: Ringing in at a lofty 10 grand your first thought might be “for a Pentax?” but the 645D is nothing to scoff at. The 40-megapixel medium format camera will feature a massive 44x33mm CCD sensor, 3.0″ 931k dot LCD display, to capture ultra sharp high-resolution images. The traditionally shaped, weather-resistant, ruggedized steel-alloy body will be compatible with existing lenses and features in-camera HDR (a feat at this resolution), shutter/aperture/ISO exposure modes,...
Summary: The 645D will no doubt attract a niche audience, though its almost-£10k price tag is firmly out of reach for the majority. The experience of using a medium format digital camera is very different from a DSLR and has many advantages, especially for landscape photographers. To be clear: the 645D is less of a studio camera than its competition, but its weather-sealed single body design firmly fixes it as one to use in the field or where large, resolute files are a must.
Excerpt: In this article we review the flagship model from Pentax, the Pentax 645D medium format camera. We contrast it to Nikon's top model, the Nikon D3x , and discuss which areas of photography the two cameras excel in. The Pentax is a medium format camera with a 33 x 44 mm sensor with 40 megapixels, and the Nikon has a 24 x 36 mm sensor with 24.5 megapixels.
[Review] Pentax 645D, the other way of shooting photos
11 June 2010
Summary: I am truly sorry if you were expecting a “Professional” review on the 645D. I have to admit that the camera’s capabilities are really exceeding my skills and knowledge here, but what I can tell you is that the 645D is an impressive piece of technology and incredible camera.
Summary: The 645D will no doubt attract a niche audience, as the almost £10,000 price tag is firmly out of reach of most amateur users. Interestingly, though, many of the features seem to be catering for a more consumer-level user, with its DSLR-styled additions and a host of auto modes. It’s not perfect, but it does have benefits and is bound to prove popular with landscape and wedding photographers alike.
Excerpt: As the manufacturer's first foray into the digital medium format arena, the Pentax 645D brings plenty of appealing features to the game, including a 40MP, 44 x 33mm, Kodak-developed CCD sensor that's designed to deliver professional image quality exceeding that of a 35mm full-frame DSLR.
Excerpt: Pentax has put a fairly aggressive cat in amongst the digital medium format pigeons and made 40 MP resolution extremely affordable, but does it have everything it needs to operate in this sector? Report by Paul Burrows. Digital medium format has been a bit of a graveyard for a number of brands over the last decade and you’d have to describe the current market as “challenging” so what makes Pentax think it can be profitable?
Conclusion: You certainly step up to a new world of image detail with this camera, and you will experience a level not found on a DSLR. The downside is that the camera is a lot bigger, slower and more expensive. We can see this camera being the start of a new generation of digital models, especially if the price comes down enough to challenge the top end of the pro DSLR market.
