Best Memory Cards for Pentax 645Z

Looking for the best SD memory cards for Pentax 645Z? Here are our top recommended & fastest SD cards for Pentax 645Z Medium Format DSLR camera.

The Pentax 645Z has dual SD memory card slots that both support the UHS-I SD cards. Designed to meet the needs of a wide range of professional photographers, whether in a commercial setting or on the side of a mountain, the Pentax 645Z (Amazon, B&H, Adorama) features a 43.8 x 32.8 mm CMOS sensor with 51.4 effective megapixels and offers class leading speed and response with 3 frames per second continuous shooting and fast image review and transfer. With the size of approximately 1.7-times larger than a 35mm full-frame format, a higher degree of the sharpness and atmosphere of the scene can be captured. Also, because the depth of field is shallow, the blurring effects can be controlled freely. The sensor is designed without an anti-aliasing filter to maximize sharpness and details. RAW files can be recorded at 14-bit and saved using either the proprietary PEF format or Adobe’s DNG format. An ISO range from 100-204,800 and high S/N ratio provides low noise, low light capability, and the Prime III image processor lends itself to fast image capture with a maximum of 3 fps continuous shooting. Full HD 1080 60i/30p/24p video capture is supported in the H.264 format with a dedicated button for instant switchover from stills to video. A 3.2″, 1037k-dot, tilting, air-gapless, LCD monitor enables live view composition and playback viewing from a various angles and a trapezoid-shaped glass prism viewfinder with Kepler telescope-type eyepiece unit provides traditional eye-level composition. Together with the optical performance of PENTAX 645 lenses, the Pentax 645Z produces unsurpassed resolution and smooth gradation representations and the three-dimensional feeling and atmosphere that will overwhelm the viewers.

As we mentioned above, the Pentax 645Z has two SD card slots that are limited to UHS-I speeds. That means it can’t get any extra write speed benefit from the fast UHS-II cards, but it can still take advantage of the fast read speeds of UHS-II cards, which enables you to transfer files to your computer quicker. So, in order to get the best out of your camera, here we list the top recommended SD cards for Pentax 645Z DSLR camera based on the speed and price. Just choose the one you like!
