judybabinski Posted July 8, 2007 Share #1 Posted July 8, 2007 Advertisement (gone after registration) Maybe this should go in the Customer forum, but the M8 forum seems to have all the action. Has anyone else had the following problem? I've had my 28mm f2 Summicron for about 3.5 years. It is the 11604 model. This winter after I got my M8, I suddenly could not fit the lens hood on the lens. (I don't think the two events are related, but I am trying to make this appropriate to the M8 forum.) It just won't go on no matter how hard I try. I also had the same problem with an old (circa 1986) 50mm f2 Summicron. In fact, I messed up the f stop ring on the 50mm lens trying to force the lens hood on, that is, turning the f stop ring does not effect the aperture opening anymore. So I am reluctant to try and force the hood on the 28mm lens since it is such a great lens on the M8. Any help would be appreciated.

carstenw Posted July 8, 2007 Share #2 Posted July 8, 2007 The hood is a very tight fit, even on a brand-new, perfect lens. Are you sure that you are pushing the little buttons hard enough to get the tabs out of the way, and then sliding it on very straight, while making little left-and-right twists?

judybabinski Posted July 8, 2007 Author Share #3 Posted July 8, 2007 I am pushing really hard and lining it up carefully. I don't think I have done the left and right twists. Will try that. Is it possible to put a small amount of grease on the tabs to make them go in further or would the grease work its way into the lens and damage it somehow?

gravastar Posted July 8, 2007 Share #4 Posted July 8, 2007 Although this won't help you with your immediate problem the information may be useful. When the lens is on the M8 I gave up using the original hood supplied with the 2/28. Instead I use the one intended for the 35mm ASPH Summilux, hood part number 12589. The lens field of view is reduced by 1.3x on the M8 so the 35mm hood doesn't vignette. It obstructs less of the viewfinder and is much smaller and more convenient. Only downside is like the original it's a tight fit on the lens barrel and the locking mechanism is a bit fiddley. Bob. Link to post Share on other sites More sharing options...
colorflow Posted July 9, 2007 Share #5 Posted July 9, 2007 I assume you are lining up the white dot on the hood with the white dot on the lens and not trying to mount the hood up-side-down? Alan Link to post Share on other sites More sharing options...
carstenw Posted July 9, 2007 Share #6 Posted July 9, 2007 I wouldn't use any grease, since yeah, it could work its way into the lens. Perhaps a tiny little bit, if you were really careful not to get it near any openings, and then immediately wiped it all away once the hood was on... The 35 Lux ASPH hood advice is good advice, the 28 Cron hood is rather large. Link to post Share on other sites More sharing options...
judybabinski Posted July 9, 2007 Author Share #7 Posted July 9, 2007 Advertisement (gone after registration) Thanks. I may try the 35Lux hood depending on how much it will cost. I am lining up the white mark. I don't understand why it suddenly stopped working. I had taken the hood off various times in the past and was able to get it back on. The lens was not dropped or banged against something. Maybe I will try cleaning the hood in case there is any build up of crud on it. Anyway, thanks for your comments.

gravastar Posted July 9, 2007 Share #8 Posted July 9, 2007 Just a random thought. You haven't added a filter to the lens have you? I have a 21/2.8 ASPH whose hood is a very tight fit (almost impossible) unless I unscrew the filter a fraction of a turn so it's loose. I can see no reason why this should be so, the filter outside diameter is less than the inside of the hood. Bob. Link to post Share on other sites More sharing options...
ho_co Posted July 10, 2007 Share #9 Posted July 10, 2007 Bob has a good point, Judy. I think some have remarked previously that some hoods simply won't fit over non-Leica brand filters, but will work fine with the Leica versions. Only other possible problem I can think of would be that the hood somehow got bent. Someone already mentioned being sure that the locking teeth are retracting all the way when you press the locking tabs. Lubrication is a bad idea IMHO, because it would just attract gunk that would make the problem worse next time. Anyway, good luck! --HC Link to post Share on other sites More sharing options...
Speenth Posted July 10, 2007 Share #10 Posted July 10, 2007 I have this problem - a solution that works with hard plastic stuff generally, is to apply a good quality, non-abrasive car polish! I use 'Autoglym'. It leaves a powdery residue which must be thoroughly polished off, but afterwards the hood slides on much better. Link to post Share on other sites More sharing options...
stunsworth Posted July 10, 2007 Share #11 Posted July 10, 2007 Are you using a b&w slim filter? The lens hood on my 24mm won't fit if I use a slim filter as the diameter of the filter ring is slightly wider than the standard filter. So although the filter fits the lens ok, the lens hood can't fit over the filter. No problem with the standard filter, the fit is tight but that's all.

I stopped using mine on my 35 Lux and replaced it with a Contax (GG-2) screw-in hood, because it was blocking too much of the framelines. I cut a vent in the Contax hood and it barely intrudes on the viewfinder. Given that the 28 has an even wider field of view than the Lux, it could be a problem for you. Check the hood for your 28 and make sure it isn't warped. Sometimes the plastic can deform if you leave it in the sun. Link to post Share on other sites More sharing options...
judybabinski Posted July 10, 2007 Author Share #13 Posted July 10, 2007 Thanks for all the suggestions. Re the filter, I took the filter ( a Leica supplied IR) off and still had the problem. Maybe the plastic is warped as I do photograph in the sun a lot in hot climates, Mexico. And I had the same problem with the hood on the older 50mm Summicron. I will try the Contax screw in hood.

clayh Posted July 10, 2007 Share #14 Posted July 10, 2007 I use the hood from the 35 lux on my 28 cron with the M8. It is smaller, and when using a smaller-than-35mm digital sensor, it blocks more unneeded light from the periphery, plus it fits better. Leica really ought to think about a line of smaller M8 hoods for all their lenses. It would reduce flare and knowing Leica's pricing policy, be a pretty profitable item for them.

thrid Posted July 10, 2007 Share #15 Posted July 10, 2007 I will try the Contax screw in hood. Thanks Judy Make sure the thread size is the same. The 35 Lux ASPH is E46, not sure what the 28 uses. Also take a look at ebay. There's a fellow called 'heavystar' who sells a lot of screw in hoods. Good stuff, I've bought two from him for my 50 and they are very nice. Cheap too.

Bill W Posted July 10, 2007 Share #16 Posted July 10, 2007 Just a thought but is the lens hood a warranty item? If you have not had it for many years, it possibly could be replaced by Leica. Link to post Share on other sites More sharing options...
lct Posted July 10, 2007 Share #17 Posted July 10, 2007 The 35Lux shade (pic 1) is more protective in case of drop or bump but screw-in ones (pic 2) make easier to rotate the aperture ring i feel. A shorter hood than the latter could be advisable for the M8 though. Link to post Share on other sites More sharing options...
judybabinski Posted July 11, 2007 Author Share #18 Posted July 11, 2007 Just a thought but is the lens hood a warranty item? If you have not had it for many years, it possibly could be replaced by Leica. Bill Thanks for the warranty idea. The lens does have a Passport warranty until April 2008. And the lens needs the coding anyway. So maybe its off to NJ! Judy Link to post Share on other sites More sharing options...
