Attaching the Lens to the Camera
Please refer to your camera’s manual for further information on attaching and removing. Check that the lens is attached securely.
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.
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.
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.
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.
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.
If you’re using a digital camera with a live view feature, you can use the zoom-in function to fine-tune the focus.

Troubleshooting
Taking photographs
Condition| Cause| Remedial action
The shutter doesn’t release.| 1. The shooting mode doesn’t support the
attached lens.
2. The camera isn’t set correctly, or the camera is set to disable the
shutter release when a lens without electrical contacts is used.
3. The camera’s focus mode is set to “AF” (auto focus). In the AF mode the
camera may not be able to detect the focus position of this lens, in which
case the shutter doesn’t release.| 01.2. Set the necessary items beforehand by
referring to 3, “Setting Up the Camera”, and your camera’s manual
1. Set the camera’s focus mode to “MF” (manual focus).
The camera’s finder display or LCD screen doesn’t come on.| 1. This lens has
no electrical contacts. so it doesn’t send or receive electrical signals
to/from the camera.| 1. Neither the camera nor the lens function is affected.
Images become blurry.| 1. The hand shakes when photo- graphs are taken.
2. The distance to the subject is too close.
3. Effects of dust and water vapor in the air.
4. The lens is dirty.| 1. Firmly secure the camera when taking photographs.
- The use of a tripod or monopod is recommended.
1. Increase the distance from the subject.
2. Take photographs in a place with less airbome dust, water vapor, exhaust gases, etc.
3. Wipe clean the lens using a soft cloth.
[Refer to 5, “Taking Photographs.”)
The camera doesn’t zoom in.| This lens is a mono-focal lens.|
Auto focus doesn’t work.| 1. This lens is a manual focus lens.| 1. Tum the focus ring and manually adjust the focus. Meter to 5, “Taking Photographs.”)
The aperture can’t be adjusted.| 1. This lens has a fixed aperture.| 1. Adjust the exposure by changing the shutter speed. Hofer to 5. “Taking Photographs.”)
What appears to be a black cap at the center of the object lens (lens on the subject side) doesn’t come off.| 1. This is the part of the lens structure that is used to reflect images.| 1. Do not remove the black object. It’s okay to take a photograph as is.
Photographs are all white or all black.| 1. The exposure is significantly off.| 1. On cameras with aperture priority mode, this problem can be compensated to some extent by correcting the exposure. On models that only have the “M (manual)” mode, the lens is linked neither to the AE function nor to the exposure meter in the camera.
When using such a camera, refer to the instruction manual for information on the appropriate shutter speed.
