Which type 35mm Summicron do I have?

My Summicron has no front ring. It is missing.<br />The lens is chrome, and it is made in Canada. There are no goggles.<br />Disrance scales: black for meter, and red for feet.<br />Where would I find the serial number if the front label is missing?<br />It seems to have an infinity lock.<br />f stops go from 2 to 16.<br /><br />Help?<br /><br />While we are on this topic, does anyone have a 'spare front ring" from a smashed Summicron?

If it's chrome it might be the famous v1 8-element summicron. Is the infinity lock the wide thumb support?

<p>Hi Huub,<br>

It is a wide thumb support like stop.<br>

Once I get home I can post a pic of the lens.</p>

 

<p>I now think that this is a V1 Cron.</p>

<p>Only the v1 Summicron had an infinity lock.</p>

<p>The serial number is on the (missing) front ring. Check with DAG for a replacement.</p>

<p>Bill,<br>

DAG has no more replacement front rings.</p>

 

<p>You can also check with Sherry at Golden Touch for the missing part.</p>

<p>This is a good tip, Elijah. I will look for her email address.</p>

<p>Can you show us some images of the lens?</p>

<p>Will do. I will get the camera.</p>

<p>Hi Raid<br>

Check your email for Golden Touch address.<br>

<p>I just need the front ring for the Cron. The glass looks to be very clean.</p>

<p>It appears your lens is the first version M mount, (1958-1969). Some of the first version were manufactured in Canada, as this lens obviously was. Perhaps you can find a parts lens on eBay. </p>

<p>It is impossible to tell from your photos but some screwmount versions of this lens were factory fitted and sold new with an M mount adapter which is held in place by a single screw. If you happen to have a lens like that, it is very rare.</p>
