Pentax 645Z PDF User Manual

Did you lose or misplace the instruction manual that came with your Pentax 645Z? It happens all too easily, but fortunately Pentax makes a soft copy available that you can browse through online, print out, or download (see the pdf file below). It is certainly good practice to carefully familiarize oneself with the many different functionalities and options that the 645Z offers, and the official user manual is without doubt an authoritative and comprehensive source of respective information.

That said, the instruction booklet can be a dry read, so that a dedicated camera guide book from a professional photographer that illustrates the camera's core functions in a real life photography context can be a very helpful complement. Yes, getting one of these camera guides (see here at amazon) would involve an additional expense, but if that book helps to exploit the camera's potential to the full, the (small) additional investment may well be worth it.

Also, you might want to check out the video tutorial on the Pentax 645Z below.

In any case, the 645Z is an advanced imaging tool, whose many features merit serious attention. This DSLR (Digital Single Lens Reflex) camera was revealed to the public on April 15th, 2014, which means that, as of today, the camera is 3085 days old (young?). Given that the 645Z is a relatively recent model, it forms part of the current Pentax product line-up.

Pentax 645Z FAQ

Below are some additional questions and answers concerning some particular features of the 645Z.

What technology is the imaging sensor in the 645Z based on?

The camera features a CMOS (Complementary Metal–Oxide–Semiconductor) sensor.

Which image processing chip is used to convert the raw signal into an image file and perform noise reduction and image sharpening?

Pentax equipped the 645Z with the PRIME III image processor.

What is the ISO sensitivity range of the 645Z?

The camera has a native sensitivity range from ISO 100 to ISO 204800.

What is the life expectancy of the shutter in the Pentax 645Z?

Pentax mentions a shutter rating of 100 000 actuations for the 645Z. This number represents a Mean Time before Failure, that is an average value. The shutter might fail earlier, or it might last longer. Anyway, in order to exhaust the expected shutter life of the 645Z over, say, three years, one would have to take about 100 pictures each and every day.

How do I find the shutter count on my 645Z?

Pentax embeds the number of shutter actuations in image metadata. You can check the number of shots that your 645Z has taken up to now by uploading a recent image to the free online shutter count finder app.

Do I need to purchase an external camera trigger to shoot time-lapse sequences?

No, the Pentax 645Z has an intervalometer built-in, so that low frequency shooting (for example, flower blooming, sunset, moon rise) can be undertaken without the need to purchase a separate external intervalometer and related software.

Is it difficult to use manual focus lenses with the Pentax 645Z?

The 645Z offers focus peaking as a manual focus aid. This feature works by placing a colored highlight on in-focus zones within the image.

What is the fastest shutter speed that can be used with flash?

The 645Z's flash sync speed is 1/125 sec.

Does the Pentax 645Z support the Ultra High Speed (UHS) bus interface for SD cards?

Yes, the camera can indeed use UHS-I cards (data transfer speed of up to 104 MB/s).

Which battery does the 645Z use?

The camera gets its power from the D-LI90 (here at amazon), which is a rechargeable Lithium-Ion power pack.
