The title should explain my question to some degree, as I try to decide whether or not to buy a TC-14E of some description for my 300mm f/4 AFS lens.
I did mean Telephoto though - not zoom - my bad
Below is a crop showing around 20% of an original from a handheld photo at Kangaroo Island last week.
Taken with a D610, I could have alternatively used the D7000 and cropped less albeit with less resolution.
Given the ratings for the TC-14s suggest a 5% reduction in sharpness, how does this number for the D610 shot, relate qualitatively to the decrease in detail I would have had from the D7000 on its own?
Has anyone seen or done the math / numbers / comparisons for this kind of question?
