Yesterday the N6006 I inherited form my dad broke the latch that holds the door closed. I ordered a few things from KEH and got 3 AS IS N6006's at 2.49 each. Hopefully one of them will have a film door in good condition and I can put it on my dad's. Is it easy to get the door off?
You should be able to swap the back by removing the bottom cover, there's no electronics involved.
The battery cover's going to be loose and the RW switch shouldn't be a problem if it's not moved when the bottom's off.
Nope, no reflection on the final picture quality apart under or over-exposure.
The "performance" of the meter depends on your "own performance" to see if the meter is telling you nice things or porkies.
The meter in the F601 is a Matrix meter with AF lenses. The same as the F801 for all effects.
Otherwise you have the standard 60/40 centre-weight meter and a nice spot meter with all lenses.
I discovered to my chagrin that the back of the camera has enough inertia when just allowed to fall closed to snap the latching hook on an N4004. I've been really careful about that since with my N6006.
The door on this camera was a known problem, it has a very cheap plastic hook under pressure from a metal lock. I left two in drawer for a few years, and when I came to use them both had broken their latch under the pressure of being closed!
For some years a company offered replacement metal hooks on ebay, but if you opted to fit your own it was a fiddly job involving tiny screws which had to be on precise alignment. The N6006/F601 was a nice camera let down by a Christmas cracker rear door.
Nikon lenses of the N6006 era were Nikon AF, pre-D and G. The IQ was excellent, though like nearly all autofocus lenses, nowhere close to the build quality of the manual Nikkors. The Nikkormat is in a completely different league of structural integrity to the N6006. The first is Olympian, the second wouldn't make it off the starting blocks at a school sports day.
