Engraving Styles and Fonts
Subtle shifts in the font used for lens markings (e.g., focal length, aperture values, serial number) or variations in the depth and sharpness of engravings can indicate different manufacturing periods. Changes in the style or placement of the “Leica” logo itself may also be present. Examination of these engraving details, compared against known samples, aids in refining the date estimate.
-
Finish and Coating Textures
Minor alterations in the surface finish of the lens barrel or focusing ring can occur due to changes in manufacturing processes or materials. The type of black anodization, the texture of the knurling on focusing and aperture rings, or the reflectivity of the lens coating can exhibit subtle differences. These textural variations, while often minimal, can correlate with specific production timelines.
-
Material Composition of Components
In some cases, subtle changes in the materials used for smaller components, such as screws, aperture blades, or internal spacers, may be observable. These alterations might reflect sourcing adjustments or cost-optimization measures introduced during the lens’s production. Documentation of such material variations contributes to a more comprehensive understanding of the lens’s manufacturing history.
-
Color Variations in Markings
The color of the paint used for filling engraved markings on the lens can vary slightly between production batches. For example, the shade of white or yellow used for aperture markings might exhibit subtle differences. These color variations, when compared across multiple samples, can assist in distinguishing between lenses produced at different times.
In summation, cosmetic variations, though often subtle, offer valuable supplementary information for determining the production year of the Leica R 35mm Summicron V2.

Understanding these performance nuances is vital for assessing a particular lens’s suitability for specific photographic applications.
-
Sharpness and Resolution
Sharpness, the lens’s ability to render fine details distinctly, and resolution, its capacity to resolve closely spaced lines, are critical performance indicators. The V2’s optical formula and lens coatings directly influence its sharpness, particularly at wider apertures. Older lenses may exhibit softer corners or lower overall resolution compared to later iterations. These factors play a significant role in its appeal for landscape or architectural photography.
-
Contrast and Color Rendition
A lens’s ability to accurately reproduce contrast and colors contributes significantly to the overall aesthetic of an image. The V2’s lens coatings affect light transmission and flare reduction, impacting contrast levels. Different coating technologies employed in varying production years influence color neutrality and saturation. Some photographers seek the unique color signature or contrast profile of a specific era of lens production.
-
Distortion and Aberrations
Distortion (straight lines appearing curved) and aberrations (optical imperfections causing image blurring or color fringing) are inherent to lens design. The V2’s design aims to minimize these issues, but the degree of correction can vary. Evaluating these characteristics helps determine the lens’s suitability for applications demanding precise image geometry, such as architectural or technical photography.
-
Bokeh and Depth of Field
Bokeh, the aesthetic quality of out-of-focus areas, and depth of field, the range of distances that appear acceptably sharp, are important considerations for portrait and close-up photography. The V2’s aperture design and optical characteristics influence bokeh smoothness and depth-of-field control. Preferences for specific bokeh styles often guide lens selection.
In conclusion, the performance characteristics of a Leica R 35mm Summicron, particularly sharpness, contrast, distortion, and bokeh, are intricately linked to its production year and version.

6. Market Value
The market value of a Leica R 35mm Summicron lens is directly influenced by the year of its manufacture and its version number, particularly when considering the V2 variant. Scarcity, optical performance, and condition collectively dictate the price a specific lens commands in the secondary market. Lenses manufactured during specific, shorter production runs generally achieve higher values due to their relative rarity. Furthermore, if the V2 exhibits demonstrable improvements in optical characteristics compared to its predecessor, such as enhanced sharpness or reduced distortion, its desirability and, consequently, its market value increase. Excellent cosmetic and mechanical condition further elevates its price point.
Understanding the interplay between production year, version, and market value has practical implications for both buyers and sellers. For instance, a V2 lens confirmed to be from an early production batch, exhibiting pristine condition, may fetch a premium price among collectors. Conversely, identifying a lens as a later production V2 allows for a more accurate assessment of its value, potentially preventing overpayment. Real-world examples of online auctions and camera marketplaces illustrate this dynamic; lenses with clearly documented production years and demonstrable optical superiority consistently achieve higher sale prices. The condition of the lens, indicated through the presence of scratches, dust, or fungus, has a significant impact on the final market value.
In summary, the market value of the Leica R 35mm Summicron V2 is not merely a matter of subjective appreciation but is grounded in tangible factors such as production year, verifiable optical performance, and objectively assessed condition. A thorough understanding of these elements enables informed transactions and accurate valuation of this lens in the collector and photography communities. Challenges persist in consistently authenticating production dates and assessing internal optical condition; professional appraisals may be warranted for high-value transactions.
