MS Optical Super Triplet Perar 3.5/35 Mark II

We are pleased to announce the availability of a second run of this popular lens. It is available for order now in our web shop.

The MS Optical Super Triplet Perar 3.5/35 Mark II is optically identical to first version. In this revision, some minor changes were made:

  • Native Leica M mount, not LTM with adapter
  • More robust, thicker focussing lever
  • Minor changes of markings on barrel, aperture scale marks


As you well know, on Friday, March 11th 2011, a strong earthquake and tsunami struck the eastern coast of Japan. Apart from the shocking damages and casualties caused by these natural disasters, the Fukushima Dai-Ichi nuclear power station suffered a severe accident spreading radioactive materials over a vast area, a crisis which is still ongoing. Incidentally, the earthquake also caused some disruption to the production process of the Perar, spoiling a lot of about 50 optical lenses.

Following suggestions from our customers, we have therefore added a voluntary option to donate a modest amount to the Japanese Red Cross (or other charitable organisation) as part of your purchase. The initial amount is set to ¥5000 which you can increase or reduce as you see fit. Thank you.

The simplest optical design that is capable of correcting all of the seven Seidel aberrations over a wide field of view is the Cooke triplet, developed by H. Dennis Taylor in 1893. It is named after the optical company in York, England, for which Taylor worked at the time, Cooke and Sons (later to become Cooke, Troughton and Sims). Taylor’s designs, despite their antiquity, are close to optimum for the aperture and field he intended, given the glass types available in his day.

However, at around 1925 with the rise of the Tessar lens designed by Paul Rudolph of Zeiss the Cooke triplet was starting to be relegated to cheaper lenses such as those in compact cameras, due to its simple design affording low cost manufacturing.

Mr Miyazaki of MS Optical, a small independent manufacturer of lenses and camera accessories, believes that a well-designed triplet is superior to the Tessar. Only very few lenses in history exploited the full power of the formula, such as an early version of the Leitz Elmar 90/4 with three elements. He started researching and designing his own ideal triplet lens at the highest level possible, using 21st century materials and manufacturing techniques. The result is the MS Super Triplet Perar 3.5/35, which has just been released. (For those wondering about the origin of the lens name, in Japanese pera-pera means thin or flimsy.)

Despite it’s deceptively simple construction of three lens elements Miyazaki was able to design a lens of not only outstanding performance, but also with a very interesting form factor and at comparatively low cost.

Here are its key features:

  • Very high optical quality triplet formula lens
  • Ultra compact design, weight 75g, collapsible (4.2mm height when collapsed)
  • Premium quality Tantalum glass, superior to Trium and Lanthanum glass with best refractive qualities
  • Refined triplet design with two double thickness positive lenses, superior to Tessar design
  • Round aperture for smooth and pleasing bokeh (Edmund Optics, Made in USA)
  • Minimum focus distance 0.8m
  • ALL glass surfaces multicoated, 97% light transmission
  • Vivid, real and beautiful color reproduction, high contrast high resolution images
  • Second lot of 200 lenses (serial 201-400), designed, manufactured and hand-assembled in Japan by Mr Sadoyasu Miyazaki

The MS Optical Super Triplet Perar 3.5/35 Mark II is available now in our web shop.

Just like MS Optical’s lens conversions, please be aware that this lens is slightly different in operation from “normal” mass-manufactured lenses. For example, the aperture scale rotates with the whole lens barrel when the lens is focussed and there are no aperture click stops. This is not a lens for photographers who want all their lenses to function in the same way and cannot adjust to a different way of working. This is a design for the connoisseur with an appreciation for optics and their history.

I did quite some shooting yesterday with the lens [on the Leica M9 and MP] and had it compete with a 35mm Summilux aspherical lens. Obviously there are significant differences, but am quite impressed with what this little lens does. First of all the focus is perfect on the M9 and the view field is good. Bokeh is pleasant. The focussing is very smooth! I liked the hood and front and rear covers – nice detail and execution!

There is no other independent maker of Leica M mount lenses that offers the same level of quality and creativity as MS Optical in the world today. The Perar is not just a lens, it is a celebration of the spirit of photography.
