Overmyhead Posted February 1, 2013 Share #1 Â Posted February 1, 2013 Advertisement (gone after registration) Hello everyone! Â I'm new to the world of Leica and could really use some assistance in identifying a lens. It came to me from a family member who past away some time ago, and, unfortunately, I need to sell it to pay off some tuition. Â I've Googled the name 35 1.4 Summilux but it's different than most of the ones I see on Google. It's either smaller, or the same size but it has an extra button on the side that the others lack. The button stops the mechanism from rotating unless pressed. I've attached some pictures so that someone with more experience can hopefully identity the lens. I can spend my own time to investigate a fair price once I know the model name, but if you would be willing to hazard a guess I'd really appreciate that too. Â Thank you!

Erik Gunst Lund Posted February 1, 2013 Share #2  Posted February 1, 2013 Use the WIKI on the top of the page on this site and you get the lens serial # and year  35mm 1.4 Summilux II Link to post Share on other sites More sharing options...
01af Posted February 1, 2013 Share #3 Â Posted February 1, 2013 The official name of the lens is: Â Leitz Summilux 35 mm 1:1.4 (for Leica M) Â It was made ca. from 1967 to 1995. Judging from the serial number, your sample probably was made in the late '60s. Link to post Share on other sites More sharing options...
Overmyhead Posted February 1, 2013 Author Share #4 Â Posted February 1, 2013 Thank you both, and thanks for the link to the Wiki. If I'm in a similar position in the future I'll be sure to use it first. Â Just two final questions, is there a way to differentiate between models with the locking mechanism and those without? And does the colour matter? Â Â I ask because even when viewing an article on 1960's-1950's 35 1.4 Summiluxs they do not have the lock (example), and the only other model that lock I've seen was silver, while this one is bronze/gold.

farnz Posted February 1, 2013 Share #5 Â Posted February 1, 2013 Welcome to the forum, Overmyhead! Â I suspect that the reason that the infinity lock on yours is a goldy colour is that the silver plating has worn off through use and is showing the brass base metal underneath. Â The lens is quite well thought of because of its diminutive style but tends to flare badly when shot against the light giving a bright glow to some subjects. Those who prefer the 'softer' images produced prior to the introduction of aspherical lens elements and particularly those seeking the fabled 'Leica glow' often look for this lens. Â Pete.

pgk Posted February 1, 2013 Share #6 Â Posted February 1, 2013 I can spend my own time to investigate a fair price once I know the model name, but if you would be willing to hazard a guess I'd really appreciate that too. Value/price depends on a number of factors. 35mm pre-aspheric Summilux lenses are quite sought after but to obtain a good price must be fully working with smooth, accurate focusing, correctly operating aperture blades (which should be examined for both wear and oil contamination), no damage (scratches, cleaning marks, fungus, etc) to the glass, minimal internal dust, good cosmetic condition, and so on. If any of the above are less than perfect then the value has to be adjusted accordingly. Â It might be worth getting a local expert (a Leica dealer) to check the lens over, and many dealers offer a commission sale system whereby they will sell a lens for you for a commission (between 15~25% typically). If you are not very conversant with camera lenses then this may be a good route to take because a reliable dealer will obtain a good market value based on the actual condition of your lens, and will advertise it, or may even have lists of customers looking for this lens.

RoySmith Posted February 1, 2013 Share #8 Â Posted February 1, 2013 One way to get some historic sales prices is to search eBay to find the asking prices are for that lens. You can also click on <Advanced > beside the Search button and search for completed listings to see the prices that they actually sold for. Link to post Share on other sites More sharing options...
luigi bertolotti Posted February 3, 2013 Share #9 Â Posted February 3, 2013 In general, is a valuable lens, not uncommon, so you can find many evaluations on ebay and dealers on the Net; being a collectible, value is a lot depending on conditions (cosmetics, mechanics, glass... and even lens cap, hood, box can make the difference) and can span a wide range.
