T-Mount

You must adjust the position of the T-mount to adjust the position of the lens. Remove the T-mount to attach rear filters to the lens.
Use the following procedure to adjust the position of the T-mount or remove the T-mount:

* The shape of the T-mount varies among the different camera brands.

9. Outer screw (three locations)
10. Outer ring
11. Inner ring

Note:
If the outer screws (9) are loosened too much, the innerring may come off.

If the distance scale indicator mark (5) ( in Fig. 1 ) doesn't align at the top center of the lens when it is attached to the camera, make an adjustment with the following procedure:

1. Slightly loosen the outer screws (9) (three locations) as shown in Fig. 2.

• Do not loosen the screws too much, because they may cause the inner ring of the T-mount (11) ( in Fig. 2) to come off.
• Use a commercially available precision screwdriver to loosen the screws.

2. Turn the lens until the distance scale indicator comes to the center top, and then securely tighten the outer screws (9) (three locations) as shown in Fig. 2.

Use the following procedure to remove the T-mount from the lens:

1. Take the lens off the camera first.
2. Remove the T-mount from the lens by turning the T-mount counterclockwise while holding the lens with the other hand.

Setting Up the Camera

The lens has no electrical contacts, so signals aren't exchanged between camera and lens. Therefore, you will need to turn 'release shutter without lens' ON in your camera settings. For further details, please refer to your camera manual.

Lens Hood

A lens hood is designed to prevent flares and ghost images caused by strong side rays that strike the front of the lens. We recommend that you use a lens good to ensure clear photographs, and to protect the lens.

• How to attach the lens hood
  The lens hood is a screw type hood. To set the hood securely, screw it according to the arrows shown in the diagram. To remove the hood, turn it the opposite way.
  

Taking Photographs

• Preventing Blurry Images
  This lens is small and light but still has a long focal length. Telephoto lenses like this product are associated with small angle of views, and higher probabilities of blurry images due to magnification of camera shake. It is recommended that you set your camera to high sensitivity, increase shutter speed, and use a stable tripod or monopod.
  Tip:
  You can prevent blurry images by using a cable release or self-timer function. In this case, be sure to use a stable, sturdy tripod. If your camera has a mirror-up function, use the function to further reduce the possibility of blurring.
• Photographing Conditions with a Telephoto Lens
  When a telephoto lens is used, the magnification factor increases and therefore dust, water vapor and other matter suspended in the air will affect the image quality. To capture sharp images, ideally photographs should be taken on a fine day with minimum wind following several consecutive clear days, in a location not subject to exhaust gases, smoke from chimneys, etc.
  Tip:
  It is difficult to capture sharp images in mountains and coastal areas during the summer, because the air contains a considerable amount of gas and water vapor. However, your photography can be more enjoyable if you take advantage of unfavorable conditions to create works of your own, such as capturing the sea through vibrating air or shooting the ridgelines of mountains veiled in haze.
• Adjusting the Exposure
  • This lens employs reflective optics, so the aperture is fixed. The amount of light must be adjusted by changing the shutter speed (if you are using a digital camera, you can achieve this by changing ISO sensitivity). A slower shutter speed tends to cause blurry images, so it is recommended that you set your camera to high sensitivity, and use a high-sensitivity film (ISO400 or better).
  • Auto exposure is possible on nearly any camera that offers an AE function with aperture priority (except for certain Nikon and Sony models) (program AE and shutter priority AE are not possible). Set the camera without lens to the aperture priority AE mode, and then try taking photographs in a bright area and a dark area. If you notice that the shutter speed differs from one condition to the next, auto exposure is enabled.

Tip:
This lens has no electrical contacts, so signals aren't exchanged electrically between the camera and lens. The camera's finder display or LCD screen may not come on, but this will not affect the camera or lens function.

• Adjusting the Focus

  • This lens isn't linked to the auto focus function, so the focus must be adjusted manually. To bring the subject into focus, simply turn the focus ring.
  • With a telephoto lens, the depth of field (the range in which the subject can be brought into focus) becomes shallow (focus range is small), so it's difficult to adjust the focus. Use a stable tripod or monopod to adjust the focus carefully.

Tip:
Generally, a super-telephoto lens with a range of 300 mm or more will have some allowance in the position of the infinitely symbol ∞. This is because the refractive index of light in air changes as the temperature in the mirror cylinder changes, and the focus position may shift slightly as a result. Be sure to adjust the focus carefully by checking the image on the finder screen, even when capturing distant objects.

Tip:
If you're using a digital camera with a live view feature, you can use the zoom-in function to fine-tune the focus.

Performance Table

* Before attaching a filter to the front of the lens, be sure the filter won't touch the reflective part (black circle) at the center of the front surface of the lens. Specifications and exterior views are subject to change without notice for the purpose of product improvement.
