Hy all,
I just bought my housing from bs kinetics it has a standard M67mm front . The question is i just bought the INON WIDE ANGLE LENS uwl-100 67MM. AND WHEN I WANT TO SCREW IT ON IT DOESNT SCREW ON THE THREAD. Do i need a adapter for this as i tought lens and front are same mm it should screw on. Any help welcome guys:confused :

That wide angle lens comes in two different threads: 67mm type 1 and 67mm type 2.

You may need to change it out to the other type.

I too am still trying to find out what they mean by type 1 and type 2.

Metric threads are metric threads, there should not be a type difference.

Ahhha you would think so, but there are different pitch threads for metric. Same thing happens in the US, we have for example a #10 24th thread as well as a #10 32nd thread. Both machine screws would be the same size, but the number of threads per inch is different.

Now I can't explain why they would do this with a lens!?!?

At least with SAE threads a thread count per inch is specified! If metric threads have similar diameters but different thread pitches, they at least ought to call it out in the spec.
