A happy family… with stacked teleconverters

In my post about nesting Least Grebes I said I would be showing photos of the distant birds taken with my 300mm lens and stacked 1.4X and 2.0X teleconverters. Here is a photo of one of the parents is about to feed a piece of crayfish to the chicks.

Vibration is a problem with such long focal lengths so you want to employ the fastest shutter speed you dare and any way to minimize shutter curtain or mirror slap. I used the camera’s electronic shutter for this.

Least Grebe family eating a piece of crayfish. Photo by Eduardo Libby Nikon 300mm f/2.8 and stacked TC-14EII and TC-20EIII teleconverters. Processed to taste in Lightroom and Topaz Denoise A. I. (the original was captured at ISO 1800 because you need to close one stop the lens when using stacked TC’s).

In the second photo I was lucky to get a nice reflection of the blue sky. This was taken using only the 2.0X teleconverter. Both photos are cropped to about 6 MP from a 20 MP file. More than enough for printing on a magazine or book page.

Have you tried stacked teleconverters? It gets a bit technical but sometimes you just need the magnification!
