2nd page with modifs:

An appointment was taken at Pentax to discover ( too briefly ) the last medium format 645 Z featuring a new 50 megapixel CMOS sensor .

The new SLR MF is very similar to the previous model, but the grip has been redesigned and is more pleasant and reassuring. Finish " all weather " is also reassuring with the presence of joints with different sensitive areas of the device : trap for memory cards , battery cover, for ...

One of the most interesting news with the CMOS sensor is of course the possibility of a focusing on screen. It is like the body : built to resist. Small problem , however , the transmission cable is in our opinion too visible and not protected enough . This is probably a point of vulnerability. The display is fluid , even with a fairly standard interior light (200-300 lux) . Of course, you can display different grids as assistants to aid composition , a histogram display (with alerts for overexposed areas ) and an electronic level 2 axes. One complaint : the screen is not touch sensitive . Too bad, because with practise , we can select the area of ​​focus on the screen.

The new autofocus seemed really responsive ( the 645Z was equipped with a motorized lens SDM , the 55 mm f / 2,8 ) , the focus is primarily limited by the movement of the optic. Live View screen , the autofocus is " surprisingly " performance . Good, medium format SLR still very far from the reactivity of a Micro 4/3 as GX7 Panasonic or Olympus E -M1 , but do not wait two seconds before trigger . Be expected to make a final lap times , but it is promising. Of course, you can achieve focus at hand and 645Z Pentax offers an effective focus peaking , even if it is flashing .

Direct target associated with the swivel screen offers opportunities to unknown users formats means. The CMOS sensor also opens a new field of exploration : Video

Naturally, the optical viewfinder is a delight with a wide and fairly bright viewfinder , but the framing is limited to 98%. For shooting on the fly , it will be the perfect companion .

Reflex still offers a nice LCD screen reminder. It is large and legible. The dial to choose the autofocus mode is now dedicated to the picture / video pass. There are many shortcuts on the housing and the dashboard is impressive, but found very quickly its brands. The case now has three customizable configurations. An excellent point.

At the connection still two SD cards (no support for UHS- II or UHS- III standards) , but now it will be possible to plug in USB 3 . We especially expect the solution to work in online mode studio. It is scheduled for July.

These first contact with the Pentax 645Z really convinced us : the device is responsive, focusing screen is well done and offers new horizons. Construction is up to the reputation of the brand. It remains only to see the images and that's the main thing. We could not resist to shoot the 645Z in at 204 ISO 800 . Even if the body was not the final one , the pictures are really noisy , but it is primarily a marketing argument. What the photographer is waiting for , it is easy to use images 3200/6400 ISO . For this point, it will have to wait a few weeks .........
