<p>I would buy a Nikon version of the A7R, assuming it had the following:</p>
<ul>
<li>nice selection of light weight slower prime lenses from wide to short tele 24mm, 35mm, 50mm, 85mm f/2.8 type lenses that are excellent wide open,</li>
<li>it has an adapter to use the existing F mount lenses,</li>
<li>a very fast EVF with excellent manual focus capability,</li>
<li>buffer at least as good as the D800E</li>
</ul>
