Canon Serenar 100mm f/2

The Canon 100mm f/2  Serenar lens is an “S” Mount lens, designed for the Canon Rangefinder cameras of the late 1940 and 1950s.  These lenses are compatible with the Leica Thread Mount (LTM) and, using a suitable adapter, can be mounted on many modern cameras like the Ricoh GXR.  They  were marketed by Canon starting January 1959 at the price of 33,000 yen.  According to the Canon Camera Museum, this series of lenses were named “Serenar” by a Canon employee in an in-house naming contest. The word “Serenar” was coined from “Serene”, the name of the sea on the moon (the Sea of Serenity) and an adjective meaning “tranquil”.

This lens is a “Planar” design – Planar being a registered Carl-Zeiss trademark for some of their lenses as well as a general term used to describe classic anastigmatic lenses design.  This particular Canon lens boasts 6 elements in 4 groups.  The iris is made up of 13 blades, with a minimum aperture of f/22.  Aperture stops are full stops f/2, f/2.8 etc.  The aperture ring has a very firm detent and clicks in place solidly.  The lens takes 58mm filters.  It is a large lens, especially by rangefinder standards with a length of 91 mm and a very solid heft to it – as one would expect from a lens made in the late ’50s, it’s a very solid lens – all metal construction that weighs in at 515 g.  The focusing throw is long – going from the closest focus distance of 1m to infinity is a few degrees shy of a full rotation.   It’s a single helicoid design, so the Aperture ring turns as one focuses.  The focusing scale has distances in both feet and meters, engraved into the metal of the lens barrel.  The meter markings are in a bright orange color.  In addition, the lens has depth of field scale too.

It’s a lovely lens with a beautiful rendering.  I’ll have more to say about that soon.   Here’s an image that illustrates the out of focus (oof) rendering at it’s closest focusing distance of 1 m.  As you can see, it’s a brutally sharp lens – the white knight I focused on is rendered with extreme sharpness.  The foreground and background oof areas are pleasantly rendered.  Color rendition is excellent with good saturation.  Image was shot with the lens mounted on a Ricoh GXR M-mount module via a CV LTM-to-M-mount adapter.

The lens also renders expressive portraits.  This one was shot at about 1m, so it’s at the lens’ close focus limit.  It is very sharp though, to may not be the best for the soft, glamor-look portrait.

It’s a wonderful lens and definitely one that I’d love to use on my M9.  The challenge is that with an optical RF, I find that focusing lenses longer than 75mm is not very easy to do.  The central patch is too small and focusing fast lenses with critical accuracy is well nigh impossible  with any sort of reliability – for me, it’s a hit-or-miss effort, with more misses than hits.  The Ricoh GXR, with live-view and focus-peaking with magnification, offers a much better platform for fast rangefinder telephoto lenses like this Canon.

Untitled, A Miksang Moment

Every once in a while, an object of every day acquaintance pops into one’s visual awareness in a very moving way – the combination of light and shadow, color and texture suddenly pierces the constant mental chatter in a moment of pure awareness, untainted by labels and critical examination.   This was one such moment, a “Miksang” moment.

Reluctant Healer

I had the privilege of spending some time today with my friend, Susana, the Reluctant Healer.  She’s a wonderful, caring, warm human being who graces us with her friendship and her love.   I was glad to be able to shoot a series of portraits of her this afternoon, as we engaged in animated conversation.  Shot with the Ricoh GXR + A12 mount (M-mount module) + the Canon 100mm f/2 Leica LTM lens.
