Imatest score differences for 300mm F4 with TC 1.4E II -- Who is right?
7 months ago

I have been thinking about upgrading to the Nikkor AF-S 300mm f/4D IF-ED with the TC-14E II, so I did some research on the internet on how sharp that combination would be.

According to the Imatest done by Photographylife.com, this combination gets a 2550 line score in the center @ F/5.6. See here.

But according to the Imatest done by Photozone.de, this combination gets a 1847 line score in the center @ F/5.6. See here.

That is quite a difference!

My question is: Which one of these tests yields the (most) correct score for sharpness in the center @ F/5.6 for this lens with TC combination?
