Re: Pentax 6x7 eyeglass saver

[Pat White]

You can buy an actual Pentax eyecup for the 6x7.  It's only $5.99Cdn, and is 
retained by the metal eyepiece ring.  The eyecup is a big rubber item that 
looks the right size for the 6x7.  It protects eyeglasses just fine, but you 
have to be careful when closing the camera back, as the big round eyecup can 
easily get caught by the back.
