Kenmore Camera had a used Canon 2x III teleconverter for sale, so Tuesday afternoon (
7-24-18) I traded in my 2x II TC for it. I was never happy with the 2x II TC as photos taken appeared "soft." Therefore, I seldom used it. I had heard the 2x III TC produced much sharper photos, so I thought I would give it a try.
Later that evening after it had cooled down a little, I went to the Pt. Edwards eagle nest to test it out in conjunction with the 7DII + 500L telephoto lens. With the 7DII's crop factor of 1.6, the combo is equivalent to a 1600mm telephoto lens. While that may sound impressive, it is only 32x magnification. Many of the new mirrorless cameras have 60x lenses, the same as high end bird spottng scopes.
I couldn't find any eagles. The eaglet must have been hunkered down in the nest while its parent were out. I went down to the marsh, where I found one eagle in a tree by Willow Creek on the south side of the marsh. It may have been bathing before I arrived because it shook itself off.
Its mate flew in from the vicinity of the marina and perched on the family tree at the top of Pine St.
The eagle by the creek swooped down and flew to a nearby pole. It had caught something, possibly a pigeon.
A passing train scared the eagle and it flew away with its prey toward the nest. I'll try to get more photos using the 2x III TC at a location where heat waves will not be a factor.
