Saturday evening was cold and clear and a perfect time to go back to Chester Hill Lookout and take some photos.
The photos below were shot using a Sigma 150-600mm super zoom and a 1.4 teleconverter that extends the zoom to 840mm. It does a remarkable job considering that the CN Tower is located 4.75 km away.
Getting sharp images from that far away is a challenge and requires more than just a good camera and lens. It requires the right conditions, and measures to keep the camera as still as possible. Even a very slight breeze will cause the camera to move which translates into blurry images. A sturdy tripod is a must.
In addition, you can delay the shutter release. On a DSLR camera, an internal mirror flips up when the shutter releases and that movement can cause a small vibration that blurs the image. To avoid this, I set the camera to wait 3 seconds after the mirror flips before the shutter releases to provide time for the camera to settle down. It may seem crazy, but at that focal length simply breathing on the camera can cause a blurry image.
