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.

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.
