<p>I would describe the Elmar 50/3.5 as a Tessar descendant; the Heliar would, consequently, be a Tessar improvement in center sharpness.</p>
<p>Here are an Elmar versus an Heliar example. The photos were taken within moments of one another, i.e. same camera, same setting, same conditions.</p>
<p>Your can decide for yourself.</p>
<p>(BTW: they are ONLY jpegs...)</p>

<p>Photos will be uploaded... 1by1...</p>
