Hello,

If you do not have a special wrench : 85mm dia. try using a large rubber band around the kurnled part of the filter, this will help the grip and do not apply to much strengh with your fingers, because it can bend the ring and block this one against the threads

good luck

...had a similar problems year ago onto a telyt 280 (or was it a 200 f4?): extensible hood didn't allow to act on the external face of the filter ring... I put a rubber band in the INTERNAL face on the ring, used a tool ... blah, cannot describe it well in english... :confused: a hand tool to act making force with 2 pins around the internal face (blah !... how damn can you name it in english...) and i succeeded...

Hello,

The hood must go deeper than this point,

may be the hood is bended, try to check if everything is coaxial, if not, try to apply force on the hood to return circular and pass the fiter ring.

Think about the fact that this filter is not born in this place, so it must be removed.

Next step will be to go to a repair center.

Again good luck.

Looks like this:

 

 

It looks like the filter may have been too big and the previous owner took off the trim ring to get the filter on. On some Leica lenses, the hoods just make it past the Leica brand filter and other brands don't clear.

 

This is the ring on the front of the hood. It prevents the hood from going in too far and just falling off the back of the lens. If you take this ring off, try not to let the hood go back too far that it comes off the piece of felt that is used to give it some friction. They can be hard to get back on if this happens.

Hmm, try to push the filter on the sole of your shoe (prefferably a rubber sole, it has to be a bit 'sticky'), and then turn the lens, while maintaining pressure on the lens.

This way the edge of the filter should stay gripped on the rubber, so it remains stationary, while you unscrew the lens from the filter.

if you can't reach the edge of the filter with a shoo because the edge of the hood is too high, try gluing a circle of rubber on a pringles can or something like that, something with the diameter of the filter

 

I hope you understand what i'm trying to explain here.

I believe there is a serated threaded ring on the front of the hood. If this ring is removed, the hood will slide down further. I use an old inner tire tube for this, which I have cut into strips. Wrap it around the ring and turn while applying even pressure along the perimeter of the ring.

 

The trick is to apply even pressure, so that the threads do not bind while unscrewing.

 

Good luck,

 

Jan
