Contacts

[Andrew]

Thinking about adapting rings-PN-11, PK or others to E lenses-on example 200-500/5.6.
Questions: lens has 10 contacts, bodies-8, TC-14-new one 10 female and 8 male, older TC-14-ten on both ends. Which contacts are responsible for closing aperture?

I presume Dr. Lens will know the answer...

Thank you in advance, Erik!

Here is a page with all of your answers, almost,,,

But basically you need all of them to make it work,,,

Coincidentally I just today handed over an extension tube for Bjørn made out of a TC14E mark II so it can be used with AFS and the AFS E Type lenses,,,

So within The next days I'm sure Bjørn will try it out on our travels and report how it works

Please note: the linked page might not load! Just see the data in later reply.

Nikonhacker page doesn't work!

Any other solution?

Andrew, it worked for me about 10 hours ago, and now it is also dead for me.  Maybe try again in a few hours, just in case the site has been temporarily taken down.

I can tell you that in the link Pins 9 and 10 were not identified, whereas the rest were.

I'll be patient...

Thanx!

Yes aparently there is an issue with that page,,,

Anyway
The contacts are identified in Nikon service manuals (and on the circuit boards of cameras and lenses) as "A" through "J". "A" is the leftmost contact as you gaze lovingly into the lens mount of the camera. The names of the contacts vary depending on what manual you read. E and F are the "gap" contacts in older cameras.

My best guess is I or J is the new [E] Aperture,,,

The first F3-AF interface:
 

number	F3AF
A	VCC
B	Limit switch
C	Near to Far
D	Far to Near
E
F	Relative Distance
G	GND

The second AF interface, as used in 5 contact screwdriver lenses:
 

number	N50	patent
A	VCC	LCVV
B	RW1	RW1
C	SCK	LCK
D	SIO	LIO
E
F
G	DGND	PGND

The third AF interface, as used in cameras that support AF-S lenses:
 

number	N90, N70	F5	patent
A	LCVV	VCC	LCVV
B	RW1	R/W1	RW1
C	LCK	SCK	LCK
D	LIO	SI/O	LIO
E	RW2	R/W2	RW2
F	LBAT	LBAT	LBAT
G	PGND	GND	PGND

The full 10 pins from the 300mm f2.8 AF-I service manual:
 

number	300mm	protection
A	VCC	cap to PGND
B	R/W1	pull up and series
C	Clock	series
D	DATA	pull up
E	Hotline, Pulse	pull up and series
F	Power for Motor
G	Motor GND
H	Hotline, Pulse	pull up and series
I	Reserve
J	Reserve
Mount	GND
