This is a record of using the standard lens for Leica R, SUMMILUX-R 50mm F1.4 II model with a digital camera.

Table of contents


Standard lens for Leica R. Released in 1998 at the end of Leica R’s life, this is a rare lens with only about 2,700 pieces manufactured. It appears on Yahoo! Auctions and eBay from time to time, but the price is quite aggressive. The one I own is 382xxxx, made in 1998, when this lens was made in the largest quantity.
As shown in the lens comparison photo, this lens is the largest and feels heavier and more massive than other 50mm lenses due to the large number of lens elements.
The hood does not extend very far and seems to be an extra, but this is hardly a problem due to the lens’s own good backlight resistance.
The gallery shows the results of shooting with DMR (LEICA R8 +Digital Module R). Due to the sensor size, the image is cropped to about 68mm, but you can see the sharpness and softness of the lens.
With the R8’s standard split viewfinder, it is possible to focus on the subject without any problems, even with the aperture wide open.
This lens can also be used with the EOS-1DsMKIII without any problems.


Lens specification
It was released with a design change from 6 elements in 5 groups of Type I to 8 elements in 7 groups to improve image quality.
Aspherical lenses should not have been used, and we have not seen anything other than R-CAM and ROM-CAM, and from the time of production, 3CAM is not thought to have existed.
This lens has a 5-group 6-element rear lens configuration with two additional lenses, which appears to be a lens design similar to the aspherical surface of the M-type SUMMILUX released in 2006.
Since it was released later than the M-type spherical SUMMILUX, this is the last spherical SUMMILUX 50mm.
