<p>The simple way to understand what part of FOV will be cutted -- just cut from black paper a square of 70x55mm size and than cut off inside it another square of 55x41.5mm and put this frame into Pentax 67 screen. That will be FOV of any 67 lens mounted on 645 camera. I made some examples on <a href="http://skrasnov.com/pentax-67/lens-adapter-pentax-645/">my article about it</a>. Just scroll to the "Crop" section. There re two examples available.</p>

<p>Hello!<br> Answering on Q3 I did the post about Pentax 67 Auto Extension Tubes and exposure compensation: <a href="http://skrasnov.com/pentax-67/extension-tubes-exposure-compensation/">http://skrasnov.com/pentax-67/extension-tubes-exposure-compensation/</a><br> Also it contains a simple calculator that helps in this equations.</p>

<p>Here is <a href="http://skrasnov.com/pentax-67/stuck-mirror-repair/">http://skrasnov.com/pentax-67/stuck-mirror-repair/</a> my little contribution to the solution of the problem. Feel free to contact me.</p>
