 In my experience most teleconverters don't give as sharp a print as an equilivant crop from the same lens.

Tests with the Tamron 150-600 and teleconverters and filters using a lens chart showed immage degration in all cases using D610 - 24Mg. pixils

What I did for birding was buy a Nikon D5100 DX body, which gives 24Mg and 225-900mm eq. better than a crop even from a D800.
