I have spent quite a bit of this week researching lenses for possible use with the Ricoh A12 M-mount. With my penchant for Zeiss lenses, and the qualities they bring to photographic images, those were an obvious target.
With the A12 M-mount one has to remember that there is a 1.5 crop factor, which means a really wide-angle lens is needed to achieve the 35mm equivalent of a moderate 28mm wide-angle lense.
With Zeiss, the choice is the Distagon T* 18mm f/4, not the fastest of lenses but its rendition is quite wonderful and it would certainly enhance any landscape shots. The only drawback is that it is somewhat pricey.
I also looked at the Biogon T* 35mm f/2, a lens famed for its sharpness at the corners. While looking at the 35mm focal length I came across the Voigtlander Nokton Aspherical 35mm f/1.2. A second version of this lens is due in the stores in January. It is slightly lighter than the original version, which is highly sought after in the second-hand market for the qualities so eloquently admired by a Canadian photographer, known to the world only as Peter, who posts under the nom de plume of Prosophos and has a web site of the same name.
Peter aka Prosophos is a talented photographer. His people shots are something quite special. He has the knack of capturing the perfect expression in his subjects.
His field report on the original version of the Voigtlander Nokton Aspherical 35mm f/1.2 is well worth checking out.
A third focal length I have been looking at is 50mm, which would translate into a 35mm equivalent of 75mm on the GXR A12 M-mount and ideally suited to portraits. Zeiss offers two 50mm ZM lenses – the C Sonnar T* 50mm f/1.5, the ‘C’ denotes compact and classic, and the Planar T* 50mm f/2 .
The C Sonnar T* does have issues with focus shift, which Zeiss acknowledges, and involves a little more care and attention when focusing but the results can be quite sublime, as Mikael Törnwall attests on Luminous Landscape.
Törnwall reports that Zeiss recommends the C Sonnar T* is best used for “emotional, artistic, narrative images, portraits or atmospheric landscapes. For documentation or technical subjects, Zeiss recommends to stop down the lens at least to f/5.6 or to use the Planar T* 2/50 ZM lens”.
Those three focal lengths – 15mm; 35mm and 50mm – would make for an ideal three-lens outfit for the GXR A12 Mount. If I were to add one more it would be the Biogon T* 28mm f/2.8 to give me the 35mm equivalent of a 40mm lens. Remember the classic Minolta CLE film camera had a three-lens kit comprising 28mm, 40mm and 90mm lenses. The Biogon T* 28mm would help fit in with that tradition.
In doing my research, I was thankful that I am not in a position to buy at the moment. Why? None of the above mentioned lenses are in stock anywhere. They seemingly cannot be had for love nor money. The same goes for Leica M-mount lenses. With the advent of the Sony NEX cameras and the A12 M-mount is it a case of the demand for these lenses has grown to where it outstrips supply? Previously the only market for these lenses was people owning Leica, Zeiss or Voigtlander rangefinder cameras and out of those three brands, only Leica offers a digital version.
As much as the Ricoh GXR camera with the A12 M-mount holds considerable appeal in terms of size and weight — the three Zeiss lenses in my proposed three-lens kit have a combined weight just 18g heavier than my Canon 40D body – I still have reservations about using an electronic viewfinder.
I am old school and for me a camera is all about lining up a shot staring through an optical viewfinder. It is what I have been used to for more than 30 years and old habits die hard.
It may be that I am worrying unnecessarily about the EVF. If people would like to share their experiences of using a camera that relies on an EVF, I would be most grateful.
It just remains for me to wish everyone a Happy New Year and all the best for 2012.
