Pinkham and Smith P&S Soft Focus Mystery Lens

Pinkham and Smith aka P&S Visual Quality #1 Series IV B Soft Focus Lens

American made from the early 1900's to about 1930, Pinkham and Smith aka P&S lenses are among the most famous and prized large format soft focus lenses.

This particular lens is unusual and so far has its own mysteries.

Probably 95% or more P&S lenses were large format produced for 8x10 or larger film formats -- which made for very large lenses.

In P&S terminology this is a comparatively small #1 lens for 4x5 with 9" focal length (as opposed to the larger format #2, #3 and
#4 Visual Quality lenses). The diameter at both ends is 2 1/8," with a length of 3 1/2" including the mounted shutter.

# 3000 is a very high P&S serial number, perhaps the highest number known.

The meaning of the B classification is unknown in my Google research.

You can find out more about Soft Focus P&S lenses here at Antique & Classic Cameras.

Here is a list of P&S lenses and serial numbers.

It will be fun shooting this lens. Please let me know if you can help solve its mysteries.
 
The currently still available Cooke PS945 is a modern reissue of the Pinkham Smith Visual Quality IV Series II which is also a 9” lens with specs covering 4x5. It’s not the same lens as yours based on the late serial number but is it a late issue? You need to shoot with it to be sure.

I own the Cooke and can say from experience of shooting over 200 sheets of 5x7 with this lens it can cover the format with movements to infinity. It will also cover 8x10 in near portrait range. This lens out Noctilux the Noctilux. You are right the coverage not being a 8x10 lens makes it more than likely a late version of this godly piece of glass. Your P&S is a real beauty a holy grail for me!

Wanting to keep the lens as original as possible, I left the non functioning Optimo shutter attached, adding a Hasselblad 55mm extension tube

plus another Hasselblad variable 63.5mm to 85mm extension tube. Focusing range is from infinity to about 10 feet.

Adding another extension tube provides closer focusing.

Pinkham Smith fan Jim Galli helped fill in some of the blanks. P&S lenses are known for their many, often inconsistent variations.

Apparently the factory had a very creative way of inventing often obscure and mysterious P&S designations.



For some reason B said to indicate an uncatalogued lens .. hmm uncataloged focal length or f/stop or both?

This particular lens seems to be unusual in several ways, including having the highest reported P&S number at 3000.

The Series IV WITHOUT a # to indicate focal length is another oddity

# 1 = 9" # 2 = 12" # 3 = 14 # 4 = 16"

Yet another oddity are the bright white numbers which may indicate a B&J aka Burke & James refurb with lens coating from the 1950's.

At least for the shorter P&S lenses, Hasselblad 200 Series or 2000 series focal plane shutter bodies can make for easy quick and convenient Pinkham Smith shooting.
