Argote Posted March 10, 2010 Share Posted March 10, 2010 Five years after announcing its development, and following a month-long online campaign trailing the launch, Pentax has finally unveiled its much anticipated 645D medium format digital camera. The first digital version of the company's 645 medium format camera system, it features a 40MP, 44 x 33 CCD sensor, 921k dot 3.0" LCD and is compatible with the existing 645 system lenses. The camera will initially be available only in the Japanese market at a suggested retail price of ?850,000 (~ US $9,400) from May 2010. http://www.dpreview.com/news/1003/10031002pentax645d.asp It seems like an interesting development to have a medium format body under $10k Link to comment https://www.neowin.net/forum/topic/882228-pentax-unveils-40mp-645d-medium-format-dslr/ Share on other sites More sharing options...

crazzy88ss Posted March 10, 2010 Share Posted March 10, 2010 why do medium formats always have such low flash sync speed?

Yea I honestly don't see a reason for non-pro cameras to go over 12MP. Even pros are pretty happy w/ 12MP.

carmatic Posted March 10, 2010 Share Posted March 10, 2010 is there a specific reason for the megapixel count on this camera? or are we still in the age of the megapixel myth...

Draconian Guppy Posted March 10, 2010 Share Posted March 10, 2010 carmatic: The PENTAX 645D incorporates a high-performance CCD image sensor produced by Kodak. It measures 44mm by 33mm, and is approximately 1.7 times larger than its 35mm-format Link to comment https://www.neowin.net/forum/topic/882228-pentax-unveils-40mp-645d-medium-format-dslr/#findComment-592332230 Share on other sites More sharing options...
crazzy88ss Posted March 10, 2010 Share Posted March 10, 2010 is there a specific reason for the megapixel count on this camera? or are we still in the age of the megapixel myth... Megapixel myth really only applies to consumer point and shoot cameras. You can't use 12MP camera to make a giant bill board; that's when you call in the medium format cameras. They've been doing this since the days of film. The larger the piece of film the bigger you can enlarge the image. The more megapixels you have, the bigger you can enlarge the image. Check out Hasselblad: http://www.hasselbladusa.com/ They currently go up to 50MP.

carmatic Posted March 10, 2010 Share Posted March 10, 2010 Traduced on more detailed pictures :) they'll need the optics to back that up, wouldnt they? its no point having pixels which are always only slightly different in colour from its neighbours... you'd get a really smooth fuzzy picture Link to comment https://www.neowin.net/forum/topic/882228-pentax-unveils-40mp-645d-medium-format-dslr/#findComment-592332336 Share on other sites More sharing options...
Draconian Guppy Posted March 10, 2010 Share Posted March 10, 2010 on the MF topic, why is it that their max ISO is 800? You'd think that with such a massive sensor it should be able to take night shots and make them look like broad daylight!

You'd think that with such a massive sensor it should be able to take night shots and make them look like broad daylight! Not really. There are other cameras that do that and believe me, this camera is like a disposable one compared to them. Just wait for the FOVEON sensors to become mainstream.

Draconian Guppy Posted March 10, 2010 Share Posted March 10, 2010 Just wait for the FOVEON sensors to become mainstream. Sigmas sensor offering? In answer to what? High ISO on mainstream cameras or medium formats? I've read little on Foveon, since CCD and CMOS is what the Canikon duopoly is about. Though I do recall reading on dpreview, years ago when it the first sigma with FOVEON came, it wasn't on par with performance with any Canikon had to offer.

Argote Posted March 10, 2010 Author Share Posted March 10, 2010 why do medium formats always have such low flash sync speed???(1/125 on this one) The lower sync speed is because the shutter needs to travel a longer distance (due to the bigger sensor). From what I read in Wikipedia, it seems that digital medium format sensors are not the 6 x 4.5 size of the film but usually smaller (something like the size mentioned here).

You'd think that with such a massive sensor it should be able to take night shots and make them look like broad daylight! Medium formats are usually used mostly in the studio or landscape type of things. So they probably won't even need to go over ISO 400 because the lighting is controlled.

carmatic Posted March 10, 2010 Share Posted March 10, 2010 The lower sync speed is because the shutter needs to travel a longer distance (due to the bigger sensor). or maybe it is because the physical pixels on this camera's sensor is smaller than what it is in the other cameras which can do higher ISO ratings?
