 Instructions for Use 

(1) General photography when an auto extension 
tube is not used 

Photography Distance: ~ - about 2.5 ft (75 cm) (from film 
plane to subject) 
1. 

Align the 

 

mark (red) on the floating ring with the central 

index mark on the lens barrel (Fig. 2). 

2. 

Focus the camera. 

3. 

Read the bellows extension amount (mm) from the distance 
scale on the side of the camera (Fig. 3) and align it with the 
scale on the floating ring. (In this case, the white scale 
beginning with   is used. In this scale, one stop is equivalent 
to an extension of 5 mm.). 

4. 

Adjust the focus once more. 

In photographing faraway subjects, adequately sharp images 
can be obtained if the floating ring is aligned to 

 When the 

floating ring has been operated, always readjust the focus. 

(2) When using the auto extension tube No. 1 

Photography Distance: About 2.5 ft -1.9 ft (76 cm - 59 cm) 
(from film plane to subject) 

1. 

Align the red spot on the yellow No. 1 scale on the floating ring 
with the central index mark lens barrel (Fig. 4). 

2. 

Focus the camera. 

3. 

Read the bellows extension amount (mm) from the distance 
scale on the side of the camera (Fig. 3) and align it with the 
scale on the floating ring. (In this case, one stop is equivalent 
to an extension of 5 mm.). 

4.  Adjust the focus once more. 
*  If the picture is taken after step 2, an adequately sharp image can 

be obtained. When you want maximum sharpness to the outer 
edges, carry out steps 3 and 4. In this case, always readjust the 
focus. 

(3) When using the auto extension tube No-2 

Photography Distance: About 2 ft - 1.9 ft (60 cm - 56 cm) (from film 
plane to subject) 
1. 

Align the red spot on the white No. 2 scale with the central 
index mark on the lens barrel (Fig. 5). 

2. 

Focus the camera. 

3. 

Read the bellows extension amount (mm) from the distance 
scale on the side of the camera and align it with the scale on 
the floating ring. (In this case, one stop is equivalent to an 
extension of 10 mm.). 

4. 

Adjust the focus once more. 

If the picture is taken after step 2, an adequately sharp image 
can be obtained. When you want maximum sharpness to the
