Keith (M) Posted January 25, 2013 Author Share #61 Posted January 25, 2013 Advertisement (gone after registration) Very happy to hear the lens is coming so soon Keith. Like you, I only have one adapter, in my case a Voigtländer 50, which I use for all my LTM focal lengths, from 2,8cm to 13,5, on the Ms. The fact that wrong framelines come up doesn't bother me since I'm a fan of the preview lever. Looking forward to some test shots! I have to admit the collapsible is a lens I have considered a while. Cheers Well, it arrived a very short while ago. Lacking my IIIg and proper adaptor I have nevertheless fitted it to my M9 (with 90mm adaptor) for initial test purposes. The trouble is that today is a uniformly dull grey overcast day (and cold too!). First view of the combo, the lens's multi-leg journey and first test shot (M9 set to 50/f2 11819/11825/11826/11816) taken at f2, hand-held 1/90sec, ISO 500. An encouraging first result for centre-sharpness (with expected edge softness). Any further imagines from the lens, either from the M9 or IIIg will be uploaded to the 'View through older glass" thread. Of course, I now need to find a suitable lenshood - IROOA. Definitely not the SOOFM - I was not aware that Heath-Robinson had spent time in Wetzlar! Welcome, dear visitor!

wlaidlaw Posted January 25, 2013 Share #62 Posted January 25, 2013 Keith, I think Heavystar is now doing a hood which will fit the Summitar and maybe also the Summicron. New Metal Hood for Leica Summitar 50mm f/2.0. I am about to order one for my Summitar. I agree that the barn door should be left in the barn!

wizard Posted January 25, 2013 Share #63 Posted January 25, 2013 ...Of course, I now need to find a suitable lenshood - IROOA. Definitely not the SOOFM -... Keith, speaking of a suitable lenshood for your 'new' Summicron, the most practical solution may be the chrome Elmar-M lenshood (the one that screws into the filter thread). It is short, has the same diameter as the lens barrel and is very effective, due to its small diameter. I use this setup together with a screw in filter, and there is a tiny amount of vignetting in the far corners which, however, doesn't bother me as I am doing slides and the far corners get masked anyway once the slides are mounted. Another advantage of such a setup is that you can use the Summicron's regular Leica slip-on slip-off lens cover (as e.g. supplied with the Elmar-M 2.8/50 lens). Much easier than having to take off the lens cover, mount the lenshood, shoot, dismount the lenshood and put on the lens cover. Enjoy your new toy, Andy Link to post Share on other sites More sharing options...
Keith (M) Posted January 25, 2013 Author Share #64 Posted January 25, 2013 I take your point about the sequence, Andy as that is what I have to do with my Summaron 35mm f2.8 - not ideal. However, that did jolt me into trying the Summaron's hood (12585H) on the Summicron. Blush - it fits (and that might just reveal me as a relative newbie to the world of Leica). Will have to try it out in daylight to see if it vignettes but the markings on hood include a 1:2/50. I live and learn... Welcome, dear visitor!

If a lenshood is designed for inter alia a 35mm lens, then it simply cannot vignette on longer focal lengths (as it is designed to not cause vignetting even with the wider viewing angle of a 35mm lens). This lenshood is entirely fine for your Summicron, I have one, too, but as explained try to avoid the hassle involved in using it. Andy Link to post Share on other sites More sharing options...

hektor Posted January 31, 2013 Share #67 Posted January 31, 2013 Advertisement (gone after registration) Keith, if you aren't worried about dimension/weight, and want to do a significant leap in term of aperture, my advice is to search for a fine Summarit 1,5 (MUST be fine... but fine items are not rarer than fine collapsible Summicrons imho). Summarit is a BEAUTIFUL lens, fully usable at 1,5 / 2 without flare at with a very pleasant contrast... and at the apertures of an Elmar (3,5 / 4 / 5,6...) it is a very sharp lens. Better to find a late item, with good coating and std E41 filter mount ; also the hood is a slightly complicated issue... but, believe me, is one of the best lenses one can still use on a LTM camera. Dear Keith, People forget that all these lenses are over fifty years old, and even when the optics look OK to the naked eye, they are not "nagel neu". I sent my Elmar f = 5cm 1:2.8 to Solms for a complete CLA and it was worth every Euro. The results are stunning when f/2.8 is enough. I also agree with Mr Bertolotti, the Summarit is special, however it is a big lens rather out of keeping with a screw-thread camera. I use mine on an M3. When in doubt buy both, but do have them cleaned and collimated. Have fun. Justin Scott Link to post Share on other sites More sharing options...

Andy There were a number of lenshoods for the collapsible Summicron f=5cm 1:2. The first was the folding SOOFM (1954), however the subsequent ITDOO (1956) is more convenient. I use the IROOA (1959) which may not be period correct, but is easy to transfer to the eight element Summicron 1:2/35 when required. Link to post Share on other sites More sharing options...

250swb Posted February 1, 2013 Share #71 Posted February 1, 2013 Does anyone have experience with the Summitar 5cm f2 (SOORE)? The Summitar is a fine lens stopped down, but like the others shows weaknesses wide open. But that means the 'good' apertures start at f/2.8 which is an improvement over the Elmar. It is also more ergonomic compared with an early Elmar, and takes 39mm filters with an easily available adapter. Having disrespected f/2 it does produce a really nice glow so it isn't a total waste of an f/stop. The only problem I can see with a Summitar is that it seems to be the new 'sexy' lens in many quarters, and the prices have risen steeply in the last year or two.

wlaidlaw Posted February 1, 2013 Share #72 Posted February 1, 2013 A word of warning to anyone considering a Summitar and looking at one of the later hex diaphragm models. Make sure the diaphragm is working faultlessly and is rust free. Apparently the mechanism for this diaphragm is fiendishly complicated, expensive and difficult to repair, as it bulges forward when you close it down, for some obscure optical reason. Look at the leaves and make sure they all move evenly synchronised. If it has not been used for some time or the lens is cold, it is quite normal for the aperture adjustment to be quite stiff. This is particularly if the lens has never been CLA'd, like mine, as the more volatile elements of the original lubricant will have evaporated and left a more viscous remnant. However, as you warm the lens in your hand and work the aperture, it should free off and be very smooth. Given the complexity of the diaphragm mechanism, I would only use Sherry, Don, Will or Malcolm to service. I don't know if Leica Solms do them in house or out-source them to someone else (maybe Will van Manen). Leica UK, when they were at Milton Keynes, used to send their older lenses to Malcolm Taylor for any work. Wilson Link to post Share on other sites More sharing options...
hektor Posted February 2, 2013 Share #73 Posted February 2, 2013 What did they do for the lens? "They" took it apart and cleaned every component. I was told that the fine lubricant from aperture blades tends to gather on the internal glass elements each side. That is why it is recommended that lenses are left wide open when not in use, and particularly when being transported. After the aperture blades and focusing mount were relubricated, the lens was reassembled and collimated. The results were apparent. I have this done to nearly all my lenses every ten years or so, and am always surprised at the deterioration over that period even though they are well cared for in the mean time.
