<p>Hello Frank,</p>
<p>Thank you for your response. Unfortunately Nikon Canada told me that the F6 is no longer serviceable when I asked them about it back in January.</p>
<p>Here is the response from Nikon Canada, retrieved from their online communication history:</p>
<p><em>Thank you for contacting Nikon Canada.</em><br /><br /><em>Unfortunately, Nikon Japan has discontinued the parts for this product and we no longer offer repair or maintenance services for this product.</em><br /><br /><em>For a complete list of products that we can service, please see the link below:</em><br /><em>Answer Title: List of repairable Nikon products at Nikon Factory Service Centre</em><br /><em>Answer Link: <a href="https://help.nikon.ca/app/answers/detail/a_id/19313" target="_blank">https://help.nikon.ca/app/answers/detail/a_id/19313</a></em><br /><br /><em>Please contact us at <a href="http://www.nikon.ca" target="_blank">http://www.nikon.ca</a> for more sales information and application assistance. Nikon Canada Inc. would like to be of further service to you.</em><br /><br /><em>Again, thank you for your interest in Nikon Canada Inc.</em><br /><br /><em>The Nikon Team</em><br /> <br /> <em><br /></em>Indeed the F6 is not listed in the link provided.</p>
<p>The problem with my F6 is an observed inconsistent film advance. There are gaps of various widths on the film. This means I can only get 34 or 35 exposures from a nominally 36-exposure (or 37 if I'm lucky) roll.</p>
<p>In addition, during film advance, there is a strong vibration in the camera back, accompanied by a "fluttering" noise. Something akin to a helicopter rotor or a truck's jake-brakes. Not as loud, of course.</p>
