<p class="">Dear Photozone,

<p class=""> 

<p class="">I have both 70-200’s the F4 and the F2.8.

<p class="">I did some tests on the D800e and Surely the F2.8 is sharper.

<p class="">However when I added the TC1.4 on these lenses the F4 clearly won. somewhat surprising don’t you think.

<p class="">This is done with the TC1.4II,.. not sure how it will go with the new TC1.4III.

<p class=""> 

<p class="">Is this something that could be interesting to investigate for your site?

<p class=""> 

<p class="">I am a bit torn as I don’t want to take both on my shoots.

<p class="">So a good scientific test of these 2 with tc's would help me and probably also others.

<p class=""> 

<p class="">I also tested the 1.7 TC and this one is now sold! upsizing the 1.4 TC shots was clearly better in terms of resolution

<p class=""> 

<p class="">Best regards,

<p class="">Mark den Hartog
