Amazing Camera

By

from Richland, WA

I'm mainly a landscape shooter. This is my first digital medium format camera and I couldn't be happier. Dynamic range is excellent and weather sealing makes it a go anytime camera. For those rare times I'm not on a tripod, the high ISO performance means I can easily stay at shutter speeds that eliminate shake. With an adapter I can use my 67 lenses, which are still pretty inexpensive.

Great camera, bet purchase ever.

By

from Alexandria, VA

The quality and build of this camera is amazing, the resolution and dynamic range are also something incredible. The only thing I have to complain about is the auto gain on the live view that can not be turned off, hopefully they will fix that in a firmware update

I took this camera to Vancouver

By

from Los Angeles, California

I bought the Pentax 645Z on Adorama about 18 days ago. And I took the camera to Vancouver this past weekend to shoot the Seaplanes on the Bay downtown. I have also owned the Pentax 645D. The biggest improvement over the 645D is that the 645Z reads to the card much faster. After you take a photo with the 645Z, you can see the image on the screen on the back of the camera a lot quicker than you could with the 645D. This gives you quick feedback to let you know if you need to make adjustments before you take your next shots. In this regard, the 645D was slow to show you the image. And the new 645Z shows you the image fast. The image quality on the 645Z is amazing with a strong 3D look that you only get from a large medium format sensor. I can see the difference in image quality and the 3D look on the 645Z verses the 645D. The new 645Z takes a better quality photo. The larger sensor really shows a difference. I would recommend setting the 645Z (and the 645D) to autofocus just usually the AF button on the back of the camera and not using the shutter button for the autofocus. You can change this easily. See the manual. This allows you to set the focus on what you want and then compose the photo. And when you hit the shutter button, it does not reset the focus. It leaves the focus set on the object that you set it on when you earlier hit the AF button on the back of the camera. I love my new 645Z. It is a big improvement over the 645D that I used to own. On both the 645Z and the 645D, I used the 55MM weather sealed lens. The 645D is still a good camera. It is just slow to show you the image on the back of the camera after you take a shot. But the new low $4995 price is a bargain for the quality images the 645D can produce. The 645D is good. But the 645Z is great.
