Hi thanks for being able to join this group I have a lovely R5 which has a broken internal depth of field stop down mechanism , I really need a parts diagram and possible spare parts , I really like this camera and want to make it my main camera 

Can anyone please help

Spare parts are unobtainable. Better buy another body.

My R7 has the same problem. I was using it one day and the d-o-f preview became stiff; stupidly carried on trying with greater force and it snapped internally. This isn't the plastic lever breaking by the way (as is reported elsewhere) but something became disconnected internally. I had it serviced recently (to fix a couple other issues) and was told this could not be repaired as it needs parts that aren't available. 

I use it now without being able to stop-down and it's no big deal as I don't often feel the need to use it. Having said that, I'll watch this thread with interest...

To any R5/R7 owner I would advise that you get some lighter fluid and go over all the Depth of field linkages and degunge them all. I had exactly the same on an R5 that wouldn't stop down properly and since cleaning it all, it now is working fine. Lighter fluid is excellent for cleaning camera parts as it dissolves dried up lubricants and evaporates really quickly. Use it sparingly with a Q Tip - it works really well.

Too late for my R7, sadly :o(  and by the sound of it, the OP's R5, too. I won't ever try to force one again.
