How to stop clip-on round hood from rotating?

I have a 35mm summicron v4 and a 12504 clip-on round lens hood, they work pretty well together, but the hood cannot be fixed in a position, it sometimes rotates, it's not a big deal but this will potentially scratch the barrel which will affect the resale value a lot. The original square doesn't have this problem it can be fixed tightly, but I really like the look of 12504.

 

Is there any way to stop it from rotating? Thanks!!!

It is super unlikely that your lens will be collectible in your lifetime.

Just touch it up with a black marker.

 

It is already collectible, my copy is the German made silver version,  the current price of the similar condition lens is at around $3000 dollars at ebay which is even more expensive than the brand new ASPH version.

Chicken feed.

The simple answer is "no". The round hood doesn't have the tab that the rectangular hood has which fits into the recess on the lens to stop it from rotating. My experience is that taking the hood on and off causes more wear than the actual rotation of which you seem concerned; the visible wear is the patina of use of which you should be proud. In my opinion, a Leica is a high quality tool that is meant to be used and enjoyed for what it is --- just my two cents --- :)

So sell it and buy something cheaper that you don't mind scratching.

get a cheap threaded hood? The Leica hoods look nice- but they are not that great if you ask me. Recently I was shooting with a 135 and 90 elmar at a job. I went to put on my 135 hood- only to find it had got dented in my camera bag and would not mount. My 90 has the same hood- so I thought no problem- I will use that- I grabbed it- and Lo and Behold- it had also gotten dented and would not mount. I managed to massage both of them back to usability with a wooden spoon and a mallet when I got home... but I was surprised at just how soft the alloy is. The two lenses must have bumped against each other in my bag causing the dents. I had the hoods mounted backwards for storage...

both of these are lolder pre-asph lenses- so it may be that more modern hoods are stiffer- I don't have any so don't know.

Which is as it should be. The hoods have, besides the obvious function of cutting out light, the same function as a crumple zone on a car. If they were too stiff and if you should drop the camera on one of them they would not absorb the force, but transmit it to the lens and the mount, causing damage.

I happened to drop my Monochrom yesterday -stupidly- and it flattened the hood on my C-Biogon 35. But that was the only damage sustained. Not even the RF was out.

What did you do with that camera bag btw to dent the contents? A Margaret Thatcher?

I will offer a related experience. In regard to the loosely attached lens hood cap, I lost mine several times when it just fell off while I was walking (each time I was able to retrace my steps and find it).

 

The remedy: run very hot tap water over the locking edges of the rectangular cover then bend and hold the ends with the small tabs  towards the center until the cap cools. It will now be noticably tighter on the hood and, in my case, xone never falls off. Regards, Ron

You can keep the shade from turning by rolling three tiny bits of gaffers tape into a little cylinder shapes and pushing then into the lens groove. Place them properly, get into the habit of mounting the shade properly, or leave the shade on and use a lens cap over the shade when storing.

Line up the hood the way you want it, mark the rim opposite the notch in the lens.  Remove the hood, cut a small notch with dovetail in the rim of the hood.  Put a thin layer of vaseline on the lens notch and surrounding area.  Replace the hood in the proper orientation.  Use 5-minute epoxy or quick-cure polymethyl metacrylate resin to fashion a tab into the lens notch and hood notch/dovetail.  When set, remove the hood and wipe the vaseline off the lens with a Q-tip and lens cleaner.  Trim any excess/flash from the DIY tab. 

 

That said, all my lenses are scractched enough I don't care.  And I use the OEM hood on my V4.

I did something very similar by borrowing my wife's hairdryer and heating up the catch lugs and then holding in until they cooled. I expect the blisters on my fingers to heal soon  :o

I am not sure if it has been mentioned already but the best upgrade to a 12504 is the later square plastic lens hood as provided with 35/2 lenses.

This hood has a small indicator detail which will lock into a notch in the lens barrel, fixing it in place.

It also does provide a much better flare protection than the 12504.

 

Only downside: you cannot use drop in filters as with the 12504 if that's a concern.

 

Another tip: leave the square rubber cover for the hood at home where it is not as easily lost as on the lens hood, walking about.

TBH, it is not the best solution for me, I found it rather insecure, for instance doing something foolish like picking up the camera by the hood can easily result in a dropped camera. I have a 12585H hood and it is very secure and solid.
