BEFORE USING THE TC-16

(Read the following carefully and get the most out of your new AF

teleconverter TC-16 now and in the many years to come.)

Like Nikon cameras and lenses, your new teleconverter is a high-precision

instrument. Mounted between the Nikon F3AF camera body with the DX-1 AF

Finder installed, the only camera assembly the TC-16 can work

with,

it in-

creases the prime lens's effective focal length to 1.6X with but a 1-1/3 f/stop

loss in effective aperture.

You'll find your TC-16 able to work with a large number of lenses, providing

autofocus operation only

(i.e.,

focus-aid function not available) with Nikkor and

Nikon Series E lenses. A built-in micromotor enables the teleconverter lens

elements to

move,

assuring virtually instantaneous focus detection and pinpoint

subject focus.

An advanced, multiple-element lens construction ensures your teleconverter

will deliver optimum optical performance with but negligible decrease in image

quality. As with most Nikon optics, the TC-16 benefits from Nikon Integrated

Coating (NIC), applied to all air-to-glass surfaces to reduce ghost images and

flare and to make color rendition more natural-looking.

Important!

'1.

You can distinguish Al-S from Al lenses through the color of the minimum

aperture indication on the aperture-direct-readout (ADR) scales—the Al-S's

scale is engraved in orange, that of Al in white.

2.

It is impossible to attach the TC-16 to any prime lens on which another tele-

converter has been mounted.

3. If the prime lens is the 300mm f/2 IF-ED, make sure you don't use its

dedi-

cated teleconverter TC-14C at the same time.

4.

Non-AI-type lenses cannot be used with the TC-16.

5. Do not attempt to mount any lens other than those listed in the table above

(especially any Al-modified lens or other manufacturers' lenses) on the

TC-16—this will damage both lens and teleconverter.

15

CONNECTING LENS AND TELECONVERTER A„ A

2

Position the lens in the TC-16's bayonet mount with its aperture index aligned

with the TC-16's lens mounting index ®;

then,

grasping the lens aperture

ring,

turn the lens counterclockwise until it click-stops into position- (With either the

300mm f/2 IF-ED or 200mm f/2 IF-ED, you turn the TC-16 clockwise until it

click-stops into position.)

To remove: Depress the lens release button ® on the TC-16 while grasping the

lens aperture

ring,

and turn the lens clockwise until the lens aperture index is

aligned with the TC-16's lens mounting index. (As for the 300mm f/2 IF-ED or

200mm f/2 IF-ED, turn the TC-16 counterclockwise until the lens aperture index

is aligned with the TC-16's Sens mounting index.)

MOUNTING ON THE CAMERA BODY— —

B„B

2

Position the lens/teleconverter assembly in the camera's bayonet mount so

that the TC-16's camera mounting index ® is aligned with the camera's lens

mounting index. Then, grasp the aperture ring of the lens or the TC-16 and turn

the lens/teleconverter assembly counterclockwise until it click-stops into

position.

(In case of the 300mm f/2 IF-ED or 200mm f/2 IF-ED. you turn the

F3AF camera body clockwise until it clickstops into place.)

Note:

• When mounting the lens/teleconverter assembly on the F3AF camera body,

make sure with your finger that the camera's meter coupling lever is locked

in the "down" position. For further information, refer to the F3AF's instruction

manual.

To remove: Depress the tens release button on the camera body while grasp-

ing the aperture ring of the lens or the TC-16, and turn the lens/teleconverter

assembly clockwise until it comes off. (In case of the 300mm f/2 IF-ED or

200mm f/2 IF-ED, you turn the F3AF camera body counterclockwise until it

comes off.)

INITIAL PROCEDURES FOR AUTOFOCUS

PHOTOGRAPHY —C

1.

First attach the lens to the TC-16, then mount the lens/teieconverter

assembly onto the F3AF/DX-1 assembly.

2.

Slide the TC-16's ON/OF switch ® to the "ON" position as far as it wilt go-

do not slide it only part of the way,

3. Set the lens distance scale to the infinity (•») mark.

• At infinity, the focus detection range varies in accordance with the lens

in use—see following table.

4.

Lightly touching the F3AF's shutter release button will activate the micro-

motor built into the TC-16; simultaneously, the LED in-focus (••*) or focus-

impossible warning indicator f x) inside the viewfinder will tight up.

16

5. Press the shutter release button all the way to release the shutter when both

LED in-focus indicators 04) light up to indicate subject in-focus condition.

For further information on viewfinder information, etc., refer to the F3AF

camera body's instruction manual.

Notes:

1.

All focus detection operating ranges are approximate.

2.

If your subject is outside the focus detection range, the LED focus-impossible

warning indicator f x)or far-focus indicator

(-4)

will light up inside the DX-1

AF Finder. In this case, turn the prime lens's focusing ring to less than

infinity

(<*>);

the distance set now becomes the maximum shooting distance

ot the prime fens' focus detection range, so its focus detection range from

maximum to minimum is correspondingly decreased. You can then focus on

the subject even if it falls outside the range tabled.

For example, when using

50mm f/1.8 as the prime gj

m

lens,

its focus detection

(2.3

ft)

range changes as in the

following diagram.

17

3. When the distance scale of the prime lens is set to minimum or around there,

you can focus on your subject even if it is beyond the original closest shoot-

ing

distance.

Note, however, that picture quality may somewhat be impaired.

4.

If the prime lens is the 135mm f/2, make sure you set the distance scale

between infinity (») and 2m (6.6 ft) in order to obtain precise in-focus indica-

tion.

You should set it at closer than 2m (6.6

ft),

or the precise in-focus indica-

tion may not occur.

5. it takes around 0.5 sec. to automatically focus on a subject from the maxi-

mum to the minimum shooting distance.

SECONDARY PROCEDURES FOR AUTOFOCUS

PHOTOGRAPHY

As shown in the focus detection range chart (p. 17), the longer the focal length

of the lens in use, the narrower its focus detection range. To shoot a subject

that is in motion, you will need a wide autofocus operation range that covers the

distance between you and the moving subject. If you set the prime lens's dis-

tance scale at infinity, the approaching subject may fall short of the minimum

shooting distance for the focus detection range indicated.

For example, when taking a picture of a subject with a TC-16-mounted 300mm

f/2 lens within a range of 70m (229,7 ft) to 10m (32.8

ft),

which is the prime lens's

minimum focusing distance, you won't be able to shoot the subject if it comes

closer than 35m (114.5 ft) if you've set the distance scale to infinity because the

minimum shooting distance required for autofocus detection to work at this

distance is 35mm

(114.5

ft).

It is thus best to reset the prime lens's distance scale by observing the following

procedures.

1.

Detach the prime lens in use from the TC-16 and attach it to the F3AF/DX-1

assembly.

2.

Focus on the subject at its maximum shooting distance; then lock this

read-

ing on the prime lens's distance scale. (With the 300mm f/2 IF-ED, use the

lens's convenient presettable focusing ring locking screw.)

3. Remove the lens in use from the F3AF camera body and insert the TC-16

between the prime lens and the F3AF/DX-1 assembly; then set the TC-16's

ON/OFF switch to "ON".

4.

Focus on the subject at its minimum shooting distance. If both LED in-focus

indicators (X) light up, this means the distance scale preset in Step 2

enables continuous autofocus operation, But if the LED focus-impossible

warning indicator (x)* or the LED far-focus indicator (•*) lights up, this

means the subject is closer than the preset minimum shooting distance.

So,

in this case, reset the distance scale by observing the following proce-

dures.

18

(1) Turn the focusing ring of the prime lens clockwise

(i.e.,

while maintain-

ing shooting position) until both LED in-focus indicators (••^i light up.

(2) Confirm the position of the distance scale set in Step 2 and the

position reset at Step (1).

(3) During autofocus operation, move the distance scale slightly between

these two positions in accordance with the camera-to-subject dis-

tance,

and make the final adjustment with the TC-16 until both LED

in-focus indicators {••<) light up.

* fit is also possible for the LED in-focus-impossible warning indicator^ x)

to light up as a result of low subject contrast. For further information, refer

to the F3AF camera body's instruction manual.]

FOCUS LOCK BUTTON— —D

Your TC-16 is equipped with a focus lock button (T). Depressing this button

during autofocus operation will automatically lock or fix the distance in focus.

Autofocus restarts the instant you release the button. To take pictures with the

main subject off-center, follow these procedures:

1.

First, center the main subject within the viewfinder's central focusing frame.

2.

Lightly touch the shutter release button of the F3AF camera body and make

sure both LED in-focus indicators (•^O light up; then depress the locus lock

button.

3. While holding the focus lock button, recompose the picture, and depress

the shutter release button to take the picture.'

Notes:

1.

When the focus lock button is depressed, the F3AF camera body's meter

and the

DX-1

AF Finder's autofocus detecting system are automatically shut

off to save power; you have to lightly touch the camera's shutter release

button once more to activate

both;

even if at times the LED in-focus

indi-

cators (••*) do not light up, focus stays locked.

2.

Sometimes, the LED indication may change after the mirror returns to its

original position upon shutter release while the focus lock button is de-

pressed;

the focus stays locked.

3. The focus stays locked as long as you keep the focus lock button de-

pressed;

autofocus operation automatically restarts the instant you take

your finger off the button.

EXPOSURE DETERMINATION

Using the TC-16 not only increases the effective focal length by 1.6X, but also

decreases the effective aperture by a

1 -1

/3 f/stop.

Thus,

when the TC-16 teleconverter is in use, you should disregard the prime

lens's engraved aperture scale.

If the TC-16 is attached to lenses with a maximum aperture larger than f/1.8

(e.g.,

50mm f/1.2, 50mm f/1,4, 35mm f/1.4, etc.), the effective aperture becomes

f/2.9 even if the aperture is larger than f/1.8. Thus, when using fast lenses, be

sure to set the aperture to f/1.8 or smaller; otherwise, incorrect exposure will

result.

In addition, some exposure compensation will be required with lenses that have

maximum apertures larger than f/1.8. For exposure compensation based on

ASA/ISO film speed adjustment, refer to the fallowing table:

Lens Max. Aperture

f/1.2

f/1.4

Compensation Required

(at ASA/ISO 100)

2/3 f/stop underexposure

(set to ASA/ISO 160 position)

1/3 f/stop underexposure

(set to ASA/ISO 125 position)

NOTES ON THE USE OF THE TC-16

1.

The AF Teleconverter

TC-16

cannot be used with any camera other than

the Nikon F3AF with the DX-1 AF Finder attached. It provides only auto-

focus—not focus-aid—operation.

2.

When you're not using the TC-16, set its ON/OFF switch to the "OFF"

position;

otherwise the batteries of the DX-1 which power the TC-16 may

be drained.

3. During autofocus operation, hold the TC-16 properly because inadvertent

touching of the focus lock button will prevent the teleconverter's lens

elements from moving.

4.

When it is

cold,

use the optional accessory Anti-Cold Battery Holder DB-4

to stabilize the DX-1 AF Finder's battery power; if the batteries powering

the DX-1 are adversely affected by the low temperature, this will likewise

affect the TC-16's autofocus response.

TIPS ON TELECONVERTER CARE

Always keep in mind that your TC-16 is a high-precision optical accessory and

that rough, careless handling may damage it. Observe the following tips, and

the TC-16 will always work as perfectly as the day you bought it.

• Keep clean and protect the surface of the electrical contacts ® of the TC-16

from dust and dirt; otherwise, electrical malfunction may occur.

20

•

Do not

subject

the

TC-16

to

shocks—especially avoid dropping

or

banging

it on anything

hard.

•

If

condensation forms

on the

TC-16 body, wipe

it

with

a dry

soft cloth.

If it

forms on the lens itself, observe the following—

use

a

blower brush

to

clean all glass surfaces;

as

much as possible avoid

using lens tissue. Gently wipe dirt, smudges

or

fingerprints with soft cotton

moistened with

a

small amount

of

absolute alcohol, using

a

spiral motion

from center to periphery. Make sure you leave no wiping traces.

If you use ether in cleaning the lens surface, smudges may appear on

the

surface; should this happen, wipe

the

smudges with

a

cotton cloth mois-

tened with absolute alcohol.

• Altach both front and rear lens caps

BF-1

and

LF-1

to your TC-16 when stor-

ing

11

separately, preferably inside the optional lens pouch No.

61;

also, avoid

storage in a high-temperature and high-humidity place.
