Which Rodenstock Lens is my Sinaron WS 210/5.6?

[Mark Stahlke]

I have a Sinar Sinaron WS 210mm f/5.6 lens in Copal 3 shutter made by Rodenstock. The multicoated lens covers 80 degrees and takes 105mm filters. There are no stripes on the front cell.

It's either a Sironar, an APO-Sironar or an APO-Sironar-W.

Can anyone clue me in to what I have?

Thanks.

Since it does not have a stripe it is the Apo Sironar. If it had a stripe then it would be the Apo Sironar W. They are the same lens just that the one without the stripe is older. When the Apo Sironar S was introduced Rodenstock began using the stripes to differentiate between the different lens series.

Thanks Bob. I was hoping you would chime in.

True but not exclusively.

I have a Sinar Sinaron WS 210mm f/5.6 lens in Copal 3 shutter [that] takes 105mm filters.

There were APO-Sironar W lenses released without the stripe and without the W being engraved on the lens barrel.

I found references to it online when I was compiling my lens database.
That lens is the only 210/5.6 in my database that uses a 105mm filter. I own one of those lenses.

It's listed in my database as an APO-Sironar (W) since the W was not engraved.
I've not seen any reference to an APO-Sironar WS. That might indicate "Wide for Sinar".

The 105/5.6 APO with the W properly engraved is a different lens, taking a 100mm filter.

Leigh, you are complicating things.
When Rodenstock introduced the Apo Sironar it had no stripe. Neither did any of the other Rodenstock lenses.
When Rodenstock introduced the Apo Sironar S line it then started to add a stripe to each lens barrel, depending on the series. And, at that time they also changed the name of the Apo Sironar to conform to the other Sironar lenses and added the S. The last lenses to have the stripe added were the Apo Ronars which were a slower sale. Once existing factory stocks of the Apo Ronar were sold a stripe was added to the newer productions.

Obviously there were stocks on Apo Sironar N and Apo Sironar lenses in distributor and dealer inventories that had not been sold by the time the stripes were added, same with Grandagon N lenses. So while at the start of the stripes some lenses were still being sold as current models without the stripes until thos inventories were sold.

I have the same lens without the yellow stripe, this is an older version but in same lens construction.

Leigh, there were only 3 lenses in the Apo Sironar/Apo Sironar W series: the 150, the 210 and the 300mm. There was never a 105mm.

That reference to a 105mm APO was a brain-fade, occasioned by the discussion of filter sizes.

The sentence should read:
The 210/5.6 APO with the W properly engraved is a different lens, taking a 100mm filter.

Sorry for the confusion.

I have the same 210mm APO that Jesse showed just before my post, lacking the colored stripe.
