There are several test done on the canon forum with TC by Sheely & bobn2 with tc and even with a good tc on a cheap zoom you will still see an improvement. One of the biggest problems when people using tc is they never modify their technique when using a tc, what they will do is use a 2 Xconv on a 300mm 2.8 lens and still use that lens as if it was 300mm 2.8 and not change their methods of shooting to a 600mm F5.6 lens. I have some test with the D800 and a zoom with a 1.7 tc if you would like to see.

I don’t see that there would be any difference with a sensor W/o filters as both images are being shot with the same camera but at 2 different pixel density, I feel the more pixels you can put on a subject is always better, more data to work with for NR and other software adjustments. But then there is always the argument that a cropped 24mp image is good enough for most people’s uses.

The hardest part about capturing wildlife is not the photographing portion; it’s getting them to sign a model release
