I bought it and put it on a sigma 70-300 f/4 5.6 dg macro telephoto zoom lens,it goes on but won't tighten up?

As long as it stays on the lens and doesn't drop off you are probably OK. A polarizing filter needs to turn, that's how you adjust it to the maximum effect.

I've never personally used the filter on a sigma lens, but I'd assume it works the same as on a Canon lens. You will notice that the filter has two moving parts and that the front ring spins continually. The the back ring that is attached to the glass should tighten onto your lens and become secure, while the front ring will continue to spin even after the rear ring has been tightened.

I use mine on my 50mm and have the same thing but I haven't had any problems with it.

One of mine became stuck on the lens and I worked it loose using slow but firm pressure. With the lens still attached to the adapter, you might have a little more leverage. A camera repair person might anchor the camera in a vice and dislodge the adapter with a screw driver and hammer...but VERY, VERY carefully. It's not something I would try unless you are really comfortable around tools. Wish I could be of more help.

thats wierd, it shouldn be tha way... depends what you are mounting i think, ive used it with the BMCC and rokinon lenses no problem... maybe check your setpup

I am not familiar with your camera but I did google it too get an idea... I think it should as once you screw the lense into place on the adapter it actually adjusts by pressing the two parts you can see that extend which makes it clip onto the front of your lense... I have found it to be a good cheap alternative to a macro lense until I can afford a proper one... Hope this helps a little? Karen

I have this one and a friend of mine bought the Canon brand one and neither of them have tightening screws. They twist onto the front of the lens and stay on firmly, never had any problems. I prefer this one because not only is it cheaper, but it also is the same size as the end of the lens where as the Canon one is larger and looks very awkward.

Its a macro lens. Try getting as close as posible , you almost have to be touching the object with the lens for it to focus

I have a Sony HX 300 The lens hood will not fit tightly to the the lens and is prone to fall off

It shouldnt. You can put the elastic band where you want. I put mine on the rubber grip of the lens. This is the part where you twist to zoom, not the inner portion that moves when auto focusing.

I thought the same thing... after looking at it closely, you have to unscrew the wide angle lens off the bottom piece, which then becomes your macro lens. Hope that helps !

I just put it on my new manfotto tripod - it fits, but is hard to tighten the thumbscrew because the manfrotto base is large and this head is small. Not sure I am going to keep it. It tightens, but then my camera droops so maybe not tight enough or maybe the particular zoom lens I am using is too heavy.

The little black ring fell out of the wide angle lens. I put it back in and now I cannot get the macro to attach. Any ideas?

You must look at the thread size of your lens and not just what lens it is. These are two different things.

The problem is the ring interferes with the lens barrel when it's fully retracted. Zoom it out, attach the ring, then when it retracts it will not quite go in as far but will still work. I hope this helps you out altho I dont know if there is much of a loss in focal length, decide for yourself.

Is the cannon macro/telephoto? That could be a factor. Im not sure. I dont have this lens yet. Though it will be my next lens once I get this return issue with the Sigma resolved.

HI Marie. It was hard at the beginning, but it worked at the end. I too thought something was wrong! Keep trying to screw it to the end of your lens, eventually it will connect and screw properly to the lens.

Hello hello Rmauma...! The Little push-button on the side... is working... like the release-button... on your camera... Push it In... and turn the lens... same way... as your normal lenses. If the button... or the adapter is stuck... Perhaps try... to twist the adapter... just a fraction... in both directions... while pressing... on the button. This can give the Little locking pin... enough room... to Work. Now take the lens... with the adapter... one hand on each... close your eyes... and let your hands Work... Hope this will help... Greetings... Jakob.
