65mm lens

[tom_kat]

<p>I just bought a 65mm lens for a Mamiya super 23 press camera. It came with the grey viewfinder. Does anyone know how I'm supposed to focus? It's a clear viewfinder. Thanks</p>

<p>While you wait for someone who has a 65mm to respond, Robb Smith's book "Mamiya; Professional Systems Handbook" (1974)  specification of the lens says: </p>

<ul>

<li>Viewfinder field determinaion: optical viewfinder attaches to the accessory shoe.</li>

<li>Parallax correction: moveable finder eyepiece.</li>

</ul>

Which to me indicates that the 65mm is couple to the camera rangefinder allowing you to determine correct focussed distance with the rangefinder and then transferring the indicated distance on the lense to the attached viewfinder for parallax compensation much like the 75mm.</span><br /> <span style="color: #333333; font-family: georgia; font-size: 13px; line-height: 20px;">- Børre</span></p>

<p>I have a Universal with 2 lenses, (but, not the 65). It looks as if you first focus as with any other lens, then, you use the grey viewfinder to get the area that the lens covers.</p>
