Here, the DX-sized image sensor is exposed. Comparison of image sensor sizes, including Nikon DX. The Nikon DX format is an alternative name used by Nikon corporation for APS-C image sensor format being approximately 24x16 mm. Its dimensions are about 2â3 (29 mm vs 43 mm diagonal, approx.) those of the 35mm format. The format was created by Nikon for its digital SLR cameras, many of which are equipped with DX-sized sensors. DX format is very similar in size to sensors from Pentax, Sony and other camera manufacturers.
In terms of height and width, the Pentax 645Z differs little from typical full-frame cameras like the Canon EOS 5D Mark III or Nikon D800. It's actually a little bit narrower and a fair bit shorter than professional cameras like the Canon EOS 1D X or Nikon D4S, in large part because it doesn't have a portrait grip.hen I published part I of my Pentax 645Z Field Test a little before the Photokina tradeshow, I promised that another report was on the way that would look at Ricoh's mighty medium-format camera in more challenging conditions.
