Adjusting lens hood thread

[David Hughes]

Elderly filter holders used to have a spring grip on the lens side. The springs looked like this () and you pushed the ends of them to expand them and then they sprung tight around the lens. You see them on ebay from time to time. They usually took what was the old standard filter of about 1¼ to 1½" dia.

Ideal as they will fit a lot of cameras. I had one for an elderly Leica years ago and it could be used on much smaller lenses.

It's quite possible, Joao, that those are not filter threads, but the threads for the lens elements retainers. That can explain why your hood is so loose, and there is not enough thread for the hood to get a good purchase.

A Series filter holder would solve the issue. Here is an article with a chart for the Series filters and adapters sizes. Your camera would take a Series VI filter. http://throughavintagelens.com/2013/09/vintage-filter-systems/

Yes, that is a good point. The threaded part is quite short (as is the threaded ring of the hood. I'm grateful for the link,

Now the good news: the Teflon tape solved the problem. The hood does not wobble and stays in place when pulled and when I take the camera from the bag. That's what I wanted.

Thank you all

That would have been my first suggestion but view range beat me to it. Glad it worked for you. A series adapter will come in handy for when you want to use filters, and you can get a hood in the same series size.

A thought occurs! It used to be possible to buy from auto parts stores metallic tape of the sort used for pin striping cars. I had a roll of this stuff once and the stuff I had (which was chrome) was thin but very robust - stronger than normal plastic tape. Anyway it is available on eBay - I checked. Wrap it around the male threads of the hood to add thickness.

Thought two. Maybe some double sided tape applied near the inner edge of the thread so that when the hood is cinched up tight it is held in place by the tape. Again it's readily available in hardware stores and on eBay. I find the 3M stuff robust and good for lots of uses.

Thought three. Fit your hood to the lens, then using a thin strip of black tape (assuming hood and lens are black) wrap a thin strip of the tape around the joint so it straddles the hood side and the lens side of the joint. This will hold it in place though there could still be some play.

Thank you Peter M but the teflon tape solved the problem. I shot a complete roll last Sunday, camera in and out of the bag many times and the hood was always in place.
I will not explore other options for now.
