Using analog lens on DSLR?

[480sparky]

Lenses send no 0's or 1's to the camera nor does the camera send 0's or 1's to the lens. Those are electric impulses. The Digital in DSLR is because of the Sensor that records the projected image in the binary form of 0's and 1's. No Sensor, no DSLR. Sensor in the camera then you have a DSLR as you have a camera built upon the Single Lens Reflex system containing a Digital Sensor.

I'm confused. "Electric impulses" are not 'digital'? Then how does the camera know, for instance, I have a 70-200 Version I attached to it? Does the lens not send a string of 1's and 0's to the camera? Does the camera not send a string of 1's and 0's to the focus motor in the lens?

What about aperture.......especially with Nikon's new E lenses? Does the "E" stand for "Eh, you don't get it"?

Lens Serial Interface - Nikon Hacker

Simple answer: NO

So using bits & bytes isn't 'digital'? The 'chips' in lenses aren't digital?

Data is always sent one byte (8 bits) at a time, least significant bit first.

1600μs communicating with 96 KBps and 100μs for 156 KBps baudrate

E and PC-E lenses opt for purely electronic control,

This is NOT digital?

1. VCC (power)
2. RW or H/S (read/write) (becomes RW1 if teleconverter is used)
3. LCLK (serial clock) (becomes LCLK1 if teleconverter is used)
4. LIO (serial data) (becomes LIO1 if teleconverter is used)
5. (teleconverter use) RW2
6. (AF-S use) LBAT
7. PGND (ground)
8. (AF-S use) PGND (ground)
9. (teleconverter use) LCLK2 (serial clock)
10. (teleconverter use) LIO2 (serial data)
    

Nor any of this?
