I decided to post these images because of recent discussions about whether or not people should use 2x extenders. I know these are birds, but putting them in the bird subsection will prevent the converter discussion.
The photos are taken with a Nikon 400f2.8s lens. The built in 1.4 converter is being used and coupled with a 2x converter. The wren also has a 5mm extension tube for closer focus.
So, the question is are these photos sharp enough, or should people not use the converters and attempt to gain the extra reach by cropping. I believe that any loss of image quality from using the converter is more than offset by the additional reach and the ability to come closer to filling the frame, but I thought it would be interesting to see where any discussion would go. Those of you who believe that no one should use teleconverters, go ahead and have your say. The photos will be posted in the first reply.

Heavy rain, clearing, sunshine. A typical March day!

UHH Photo Gallery guidelines follow the same curious logic:

"Try to include the specifications of your gear and settings in the post accompanying the pictures. Stating aperture, shutter speed, ISO would be great. Even better would be to also include your body and lens specs. This really helps others learn what settings work in various scenarios."

In the periodic main photography discussion topics about inclusion of exif in comments, there are many who want and who feel there's value. I am not one of those
