Quick Acting Portrait Petzval 300mm F3 'Optimus' 3B

€1100.00 Sold Out

History: Perken, Son & Rayment was an early photographiy supplier based in London. They were retailers mostly, rebranding cameras and lenses with the name. Later on they also made cameras and lenses themselves. This lens is that its the top of their line 'Optimus' Quick Acting Portrait lens they offered. The most interesting part though is that is really resembles a Dallmeyer made 3B lens from that time. I had many 3Bs in my hands, and even right now, i have two here, to which i can compare the lens. The size, they barells layout, the glass size, everything has same or similar size to the Dallmeyer counterpart. Im not sure if its a rebranded Dallmeyer or a Dallmeyer clone made by Perken. I would say there are chances for both theories.

The last two pictures show a brief comparison to the 3B i have here right now. You can surely spot the similarities.



Condition: The outer housing looks good with some minimal signs of wear.  The rack & pinion mechanism is complete and workinge. The glass has some ups and downs, first thing you will see is a quite long crack in the front element of the achromat, and also quite some scratching on the glass. Still, this covers only some percentage of the front group, so it will not affect the image to a large degree. Actually i had a petzval with a similar crack and it offered the best bokeh you can ever imagine, even better then a superb looking Voigtländer or Dallmeyer. Whats more important, besides the obvious damage, the glass is clear and doesnt show any haze or fog.

The lens features a waterhouse slot (no stops included).

The lens has the same specs as a Dallmeyer 3B with a focal lenght of around 290mm (11") at a speed of F3. It will cover 5x7 format but probably the best work it does on portraits with the 8x10 format.There it shows a fantastic petzval bokeh in the out of focus area. It is very very sharp in the center, considering the nice falloff its the perfect tool for portraits in those formats.


Lens comes with the original flange (which is solidly fixed to the lens).
