A 2x TC Example

[Loupey]

Reflecting on some recent posts regarding teleconverters, I shot this heron last night and I thought it might make a good illustration of what I'm getting with the Canon 2x TC and the 300mm f/4L IS.

The first image is full-frame. The second is a crop of the same image. I did perform an initial adjustment to the Levels and Curves. But I purposefully did NOT perform any sharpening.

Specs:

Canon 300mm f/4L with 2x II TC
ISO 200
f/11
1/350s
Shooting distance: ~250 yards
Platform: monopod (didn't want to hand-hold this example)
IS: on
Air quality: humid (a couple showers just passed)

I think the 2x performed admirably. I was happy to see the eye detail and the veins on the leaves behind the heron.

Keep in mind I am working with an APS-C sized sensor and do not have a lot of pixels to work with (6.3mp Canon 10D).
