12504 shape hoods: 2-piece / 1-piece variations & opening tips.

Hello

I’ve gathered a little collection of these nice hoods. Although of the 4 pictured, I can only unscrew 2 of them into 2 pieces (black 12504 and one of the Titans).  
 

I suspect (although am not 100% sure) that the silver one just happens to be the same shape as a 12504 but is not 2 piece and not unscrew-able.  Can anyone confirm ? I think it’s originally from a Safari set. 
 

For the Titans: considering they have the same part number (12453), and that one of them is easily unscrewed ... I assume the other one is just stuck.  But stuck very well. Any tips on opening would be appreciated ! 
 

Alternatively, is it possible that one of the Titans is just one piece like the silver chrome ?   In Leica’s online store I have seen some black 12504’s (with usual 12504 part number on) that state “this hood is one piece and doesn’t hold a filter”.  So, perhaps it’s not completely unfeasible .  
 

All 4 finishes look identical around the “join” when closed. 

Thanks for any help 

Graham

To try opening your second example of the 12453 you might try to use some means for loosening filters which are stuck on lenses:

I am rather sure the silver one doesn't belong to the Summilux, since the chrome version had a completely different hood (OLLUX) and the newer version never appeared in silver chrome before the recent "Retro"-Summilux. So it seems that it either belongs to a different lens - or it's of "third party" origin (to put it mildly).

No idea but this silver one have two halves. Don't ask me more, it is not mine. To check yours, you may wish to put the hood upside down on a rubber surface (eg a rubber sole) and turn the hood anti clockwise while pressing it gently onto the rubber. May work perfectly... or not .

Thanks !   I’ll try some of the options in the thread, and fingers crossed. 
 

The silver chrome 12504-shaped hood is in brass and originates from the M-P 240 Safari Set (Originally paired with a 35:2 ASPH).  So yes, not for summilux v2’s.   I think it’s safe to assume it’s one piece and I’ll stop trying on that one

Thanks LCT.   I just read this after my previous reply just now. Ok I’ll keep going with the silver also just in case.  

Had  read your rubber trick in other posts so have tried it, no luck so far but will keep going 👍

Well, if the silver one was meant for the 35mm Summicron, it does not need to be unscrewed to take a filter, as the Summicron - other than the Summilux - has its own filter thread. Though there is the photo posted in #3 ...

Hoods are full of mysteries ...

They are indeed ! 😂

Since you started a 12504 hood thread I hope you don't mind if I ask a related question. I bought a NOS Tamron serie VII neutral density filter for mine but I can't get it to fit. As far as I can tell, with the hood separated the filter should drop in and be secured when the hood is screwed back together. But my filter diameter seems too big to allow this to happen. Any advice appreciated.

Tell us what diameter so that we can check.

Thanks. Outer diameter 57.5 mm. This is measured with a ruler so may not be absolutely accurate. 

[lct]

Too large sorry.

[sinjun]

OK thanks for checking. I thought the Serie(s) VII designation defined the size. Is this not the case?

Yes it should but 57.5mm is way too large. 50.8mm here.

[UliWer]

Usually Serie VII stands for a certain diameter. Perhaps Tamron uses this with another meaning.

You might try Serie VII filters from Heliopan, or perhaps look in the second hand market for Leica items. There are plenty of them, though perhaps neutral desity not so often to find.

Yes it looks like Tamron had another meaning for Series VII. Caveat emptor.

Sorry for highjacking the thread.

E49 B&W nano 3 stop ND filter fits in the 12504 without issues.  Right side up or upside down, usually one orientation works better than the other with E49’s.

Same for Leica E49 filters.

I'm here to piggyback on this thread.  Anyone know what lens this hood might be for?  It came with a 35 lux pre asph that I bought, and while it fits just fine, it is not the correct hood for that lens.  

It appears to be a newer 12504 type hood that doesnt separate to accommodate a filter.  The writing however is in black (instead of white) that simply says Leica Camera Germany.  All other similar hoods I've seen have white writing on them.

Hallo,

Look here: Leica M

[lct]

Looks like a 12504 hood where a previous owner would erase the white paint the same way as i sometimes do. As for the stuck halves, you may wish to try the tip above just in case.

Hello Sinjun,

What you have there might be a Series VII.5 filter. This is the filter size, for example, for a 180mm f3.4 Apo Telyt-R lens. The Series VII.5 filter on a 180mm f3.4 Apo Telyt-R uses screw on retaining ring 14222, which is 59mm X 0.75mm.

Best Regards,

Michael
