Lens Hood Question

The lens hood (12526) on my 35mm ASPH has problm staying engaged to the lens body since Day One. For the life of me I can't figure out why the two mounting tabs on the hood do not seat all the way into the recepticles/sockets in the lens body. I would like to fix it if I can before buying a new one. All advices are greatly appreciated.

Matter of tastes of course. I don't have the 35/2 asph but the 12526 and the almost identical 12524 are my favourite hoods on 35/2 IV and 28/2.8 asph lenses.

What do you mean exactly by "the two mounting tabs on the hood do not seat all the way into the recepticles/sockets"?.

Could you show a pic of your lens with the hood on?

Is it the same both ways up? The similar square hood on my Summicron 35/2 (iv) seats snugly if i put it with the serial number/part number facing up, but if put it with the brand name facing up, then it's loose. The similar hood on my Elmarit ASPH 28/2.8 works in the same way -- only fits snugly/securely one way up.

 

Might this be the case with yours too?

Alf,

 

Is there a filter on the lens that may be impeding the hood from being seated properly? I am using the same hood (actually a 12524 - practically the same) with a Leica UV/IR cut-off filter with no problems. I am sure that there must be something in the way - the hood should seat correctly unless something is wrong.

 

As Luigi mentions above, the IROOA is one option for replacement, other ones are round metal clip-in hoods nos. 12504 or, my favourite - 12585. Both have cut-out so that you can look through them when sighting through the finder.

Thanks to all for your kind replies.

 

This is a summicron. I tried to mount the hood both with the serial number facing up or down but didn't make any difference. The hood just wouldn't go all the way. There is no filter mounted on the lens.

 

By "tabs" I meant the two "fingers" on the hood, positioned at 12 and 6 o'clock. By "sockets" I meant the two holes on the lens barrel. Sorry for the confusion.

 

I will try to post a photo once I figure out how =).

Alf, it looks like it's on properly. I have that hood on mine which is also a brass lens and it doesn't push down to the beginning of the barrel proper. You need that extra little space to see the aperture index mark. Pic of mine below.

Thanks Peter for the photo. Makes sense now the index mark should be visible.

I guess the problem lies in that the spring "fingers" do not stay in the recessd groove for some reason.

I will take Jeff and LCT's suggestion to get a 12528.

 

Cheers.

Can this also be used on the summicron 50mm? the 79-94 version?

The 79-94 Summicrons 50/2 (black 11819 and silver 11825) have no stop pin preventing the 12526 or 12524 hood to rotate so given that both of the latters are square i would say it's a no no.

For 11819 and 11825 Summicrons, the regular hoods are the metal 12585 and plastic 12538 vented hoods. Both can be reversed on the lens and provide a good protection.

Purchase a Heavystars screw on hood and you will never have to worry about your hood, period. If worried about your front element, mount the correct Leica Uv filter, it won't make the slightest difference in your pictures.

My 35mm ASPH 'Lux hood has the same problem and i have a Heavystars hood mounted. No problems, no cap to remove, no hood to reverse.-Dick
