ironringer Posted December 8, 2013 Share #1 Posted December 8, 2013 Advertisement (gone after registration) Hello screwmount users: Is the front ring outside diameter of a 1950s screwmount 5cm Summitar f2, the same as the front ring outside diameter of the mid-1950s screwmount 5cm Summicron f2 lens? If so, will the interesting IROOA lens shade fit the 5cm Summitar? I understand that the typical lens shade for a screwmount 5cm Summitar f2 is the "barn doors" SOOPD but I was hoping Leica made another shade that would fit. I will wait for CLA service before using my recently purchased IIIf - the shutter is draggy and sounds very dry. I just bought a nice-looking 5cm Summitar f2 to use with it, and will need a lens shade. Regards from Montreal Link to post Share on other sites More sharing options...
Advertisement Posted December 8, 2013 Posted December 8, 2013 Hi ironringer, Take a look here shades for screwmount 5cm Summitar and Summicron?. I'm sure you'll find what you were looking for!
madNbad Posted December 8, 2013 Share #2 Posted December 8, 2013 I'm sure many others will correct me but I believe the Summitar is a 36 mm thread (good luck finding one) which is why it is difficult to find hoods and filters which will fit. I have a Summitar and have tried a couple of different adapters with no success. Good luck... Link to post Share on other sites More sharing options...
erl Posted December 8, 2013 Share #3 Posted December 8, 2013 Search HeavyStar Photo Gears web pages. I got an adapter to fit the conical front filter mount of the Summitar to convert to standard Leica 39mm. Now all my filters fit and a cheap lenshood from the same place is great. From memory it was all just a few dollars including shipping. Link to post Share on other sites More sharing options...
UliWer Posted December 8, 2013 Share #4 Posted December 8, 2013 The IROOA -or its precedessor ITDOO with the narrow chrome ridge - does fit the Summitar. On the lenses post-war version the clips fit into the slit, on the earlier version (uncoated) it is not fixed and might easily go loose. But: Those shades cover a large part of the IIIf-viewfinder. To avoid this, the barn-door shades are much more convenient. Link to post Share on other sites More sharing options...
ironringer Posted December 10, 2013 Author Share #5 Posted December 10, 2013 Thank you erl for suggesting the replica SNHOO filter adapter for the 1950s screwmount Summitar 5 cm f2 lens (36mm type L to E39mm) that is sold by "heavystar" on eBay. It could form the base for an easier-to-find 39mm lens hood. Thank you also UliWer for confirming that the (expensive!) IROOA lens hood would fit on the Summitar. I bought a SOOFM "barndoor" lens hood on eBay at a reasonable price, and its marking (Summitar u. Summicron) indicates it should work with the Summitar as well as the later screwmount Summicron lens. Has anyone tried the SOOFM with a 1950s Summitar 5 cm f2 lens? Regards from snowy Montreal Link to post Share on other sites More sharing options...
payasam Posted December 10, 2013 Share #6 Posted December 10, 2013 The SOOFM works with Summitars and is so marked. The earlier SOOPD came in three variations and was for Summitars alone. Link to post Share on other sites More sharing options...

Regards from snowy Montreal it works... even if i admit I have never liked to USE it... frankly, it's an interesting and finely engineered collectible but not so practical in usage - carrying etc... Give a look at the two discussions linked in our Wiki page : http://www.l-camera-forum.com/leica-wiki.en/index.php/SOOFM Link to post Share on other sites More sharing options...
payasam Posted December 11, 2013 Share #8 Posted December 11, 2013 It folds flat, so carrying is not a problem. In use it is a little unwieldy, but that should be balanced against its unsurpassed efficiency as a lens hood. Link to post Share on other sites More sharing options...
luigi bertolotti Posted December 11, 2013 Share #9 Posted December 11, 2013 It folds flat, so carrying is not a problem..... ... a problem with a std. leather case... but agree that is probably the most efficient 50mm hood ever made Link to post Share on other sites More sharing options...

pico Posted December 11, 2013 Share #12 Posted December 11, 2013 Ah yes, Pico. That is exactly the one I have. I agree, it is very good. I searched long for a post-WWII Summitar and found one. It is super clean, with a round aperture, and possibly coated (I cannot be sure), but I am happy with it for the rest of life. Link to post Share on other sites More sharing options...

250swb Posted December 12, 2013 Share #14 Posted December 12, 2013 A good Summitar is a great lens on any camera. I have the Heavystar adapter and it makes the whole filter and hood thing so much easier. I think a worthwhile modification is to paint the inside face matt black like the Leica original (mask the threads and outside and spray with an aerosol paint). The increased depth of the adapter starts to act as a hood in its own right, but I also use a Heavystar metal hood and lens cap that fits it.

erl Posted December 12, 2013 Share #15 Posted December 12, 2013 Indeed Steve, the adapter and even the addition of a filter when desirable extends the hood to be more effective. The one thing Leica lenses are mostly lacking is decent shading. Link to post Share on other sites More sharing options...

It is super clean, with a round aperture, and possibly coated (I cannot be sure), but I am happy with it for the rest of life. For IIIa syn I chose a Summicron 50 coll among other things because of the E 39 filter thread to avoid adapters. Do you think a coated Summitar from the postwar period as a direct precursor of the Summicron would be better? Link to post Share on other sites More sharing options...
madNbad Posted December 17, 2013 Share #17 Posted December 17, 2013 Just received a Heavy Star Summitar adapter and the lens hood. The adapter works well but have not been able to line up any of the vent cutouts with the viewfinder on my IIIc. Painted the interior of the adapter flat black and moved the hood to an M mount 50 Summicron. The hood provides better protection than the built in and It has a cap.

Painted the interior of the adapter flat black and moved the hood to an M mount 50 Summicron. The hood provides better protection than the built in and It has a cap. On my 111f I solved multiple problems by using the auxillary finder for the 5cm Summitar. I use aux finders for all lenses on the 111f. That totally solves the VF obscurement problem. I agree about the M50mm built in lens shade. It is crap. I also transfer the HeavyStar hood to it when in use. All Leica built in hoods are ineffectual. That is my only complaint with them. They are, I know , designed for compactness. Funny, I always thought they were meant for flare control. Link to post Share on other sites More sharing options...
madNbad Posted December 17, 2013 Share #19 Posted December 17, 2013 I would love to say I have always so careful as to never let my camera bump into anything but then there is reality. I just acquired the 50 (almost new at a very good price) and the only mark on it is a tiny nick in the built in hood. If a screw in hood can serve the dual purpose of flare control and keep any further damage at bay, then it's cheap insurance. Link to post Share on other sites More sharing options...
erl Posted December 17, 2013 Share #20 Posted December 17, 2013 It's more than cheap insurance, it is also a great 'ímage improver' in many flare situations, especially with the Summitar. The Cron also benefits greatly. Link to post Share on other sites More sharing options...
