i bought my summilux 50mm version 2 about a month ago. and im always very pleased with the results. but im wondering if there any differences between different types of summilux 50mm?
does the current asph version produce harsh oval bokeh as well?
apart from the sharpness & contrast, is there still any advantages over it's previous version?
thank you very much.
One range for 50mm Summicrons, another range for 35mm Summilux, etc. And one range for M2, another for M3. All like items within a given block may not have been made at the same time. I haven't seen a serial number list that breaks lenses down by type; only by the date on which the block of numbers was assigned. Serial numbers are a rough guide. Jan 17, 2011 - And another update on the serial numbers after 2004: 4 000 000-4. Leica 50mm f/1.4 Summilux-M Aspherical Manual Focus Lens (11891). This was the favourite design of Mandler himself, based on the design of the second version Summilux-M 50mm. Leica 75mm F1.4 Summilux-M Serial Numbers Overview.
I'm new to the group--awaiting my newly acquired Summilux (type 3). This lens has had the same optical formula through its first three types. The big change between type 2 and 3, imo, is the closest focusing distance from 1m to .7m. Another notable change is improved coatings over the years.
But note that the closest focusing distance for type 3 is incorrect.
type 2 - 1,844,001- ? optics changed E43
type 3 - Same optics as Type 2, but built in hood and closer focus, also E46 (known as Pre ASPH)
ASPH - E46
maybe someone can inform of missing serial numbers..
A black enameled 'old style' focusing ring, collapsible lenshood, E46 thread, produced with a black enameled range of M6 bodies.
Is it ASPH or not ? (no engraving).
Second version has new optical formula and different lens coating.
Third version has same optical formula as second version but with improved coating ( maybe cannot confirm ) and different cosmetics.
