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.

Note: we sell the MS Optical Super Triplet Perar 3.5/35 in M mount. Actually, at the core the lens is screw mount, however its use on LTM bodies requires some additional technical calibration with the camera. Unless you send us your camera, for customers outside of Japan we only offer the M mount version. The L-M ring is semi-permanently fixed and could be removed if you really wanted to, but doing so may create focussing and other issues so it is not recommended.

UPDATE: We have created a stand-alone Automator application that sets the lens name, focal length and maximum aperture of your image to MS Super Triplet Perar 35mm f/3.5 in the file’s EXIF data. (Mac OS X only). [Download]

MS Optical Micro Four-Thirds (M4/3) T mount/C mount lens connector S (Slim)

Cosmicar 12.5mm/1.4 Television lens adapted for Micro 4/3

We are pleased to announce the addition of Micro Four-Thirds (M4/3) T mount/C mount lens connector S in addition to last year’s Micro Four-Thirds (M4/3) T mount/C mount lens connector L, both made by MS Optical.

Using C mount lenses on Micro Four-Thirds digital camera bodies has become widespread and an enjoyable exploration of lens history. Adapters like these are widely available but MS Optical’s connector kit is somewhat unique – a smartly designed device, not just a piece of metal.

Not only is it made to usual MADE IN JAPAN precision, also unlike other cheaper adapters available it consists of two finely machined parts: an outer ring with a T-Mount (M42, 0.75) screw mount hole, and a smaller removable step-down ring to C-Mount.

The two-part design of this adapter is helpful in cases where, for some reason, a lens cannot be screwed into the adapter as-is or where the aperture or depth of field scales may end up in the place where you cannot see them. The screws can be loosened and the assembly turned to a position you like.

The new S version is a very slim adapter without a surrounding rim to accommodate lenses with larger diameter. However do take care not to overload this adapter. Click on the image to see side-by-side large. Price for each adapter is ¥10,900 plus shipping.

Please pay particular attention to the instructions and warnings accompanying this device as improper use may damage your lens or camera. As in the case of the Cosmicar above, we are happy to accept your C mount lens and have it fitted to the adapter professionally by Mr Miyazaki. Please contact us for details.

Important note: Note that no matter what adapter you use, the image circle of the large majority of C-mount lenses (including the Cosmicar shown here) isn’t large enough to cover the full micro Four-Thirds frame. Instead, there’ll be more or less vignetting.

Neither Japan Exposures nor MS Optical can give you advice on which lens to use. Please research this carefully on the web and note too that manufacturers often put out very different lenses with the same brand name, focal length and aperture; these may have different image circles.) (Thanks Peter)

MS-MAG x1.15 Leica M viewfinder magnifier back in stock

As we announced previously the popular MS-MAG 1.15x magnifier (announced as discontinued and sold out) is back in stock. This magnifier is of great value as on cameras with 0.85 magnification (e.g. Leica M3, Leica M6) it will result in natural view allowing shooting with both eyes open.

Thank you for your patience and those who have placed pre-orders, which will be fulfilled today.

MS-MAG x1.15 magnifier for Leica M sold out

As we noted a while ago, the production of this magnifier by MS Optical has been discontinued and it is now sold out. A lucky gentleman from Australia will receive the last item we had in stock (too bad, as I wanted to keep one of those for myself :).

There is still hope for a re-release as MS Optical indicated to me that they are contemplating manufacturing it again.
