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)
