In contrast to conventional digiscoping, where the image produced by the spotting scope eyepiece is photographed. The TSN-PA7 connects your D-SLR directly to the body of the scope via a T2 mount. Creating a high powered, yet lightweight and compact telephoto lens, when compared to traditional telephoto lenses.
Designed to be used with the Kowa TE-11WZTE-10Z zoom eyepieces and Kowa TSN-880/770 series spotting scopes. The design allows for the full use of the zoom eyepiece range giving an amazing focal length reach of up to 2570mm when using the TE-11WZ eyepiece or 2750mm with the TE-10Z.

The TSN PZ connects your D-SLR directly to the body of the scope via a T2 mount. This makes for a high powered, yet lightweight and compact telephoto lens, when compared to traditional telephoto lenses.

The TSN PZ has a variable focal length range of 680mm – 1000mm (based on 35mm), which gives you the added flexibility when composing your image. It also makes finding your subject matter easier – by zooming out to the wider angle of 680mm to locate the subject and then zooming into 1000mm for maximum telephoto power.

The pros

  • huge telephoto power
  • can keep a respectful distance from the subject
  • compact and lightweight
  • no need to carry additional gear
  • requires skill therefore more rewarding and sense of ownership

The cons

  • locating subject matter
  • missed opportunities
  • risk of motion blur
  • moving subject matter
  • small apertures

The challenges: 

  • Bright cliff face with a black coloured bird.

Set the camera to AE mode and under expose so to avoid highlights blowing. Lighten the subject in post processing as required.

  • Windy conditions

Set the tripod low to the ground and set a higher iso on the camera to achieve faster shutter speeds to minimise motion blur.

  • Fluctuating lighting conditions

Continuously monitor shutter speeds and adjust settings to suit.
Check image playback to monitor sharpness of image and histogram.
Check focus and fine tune if required.
