FarpointBahtinov Masks for Camera Lenses (52mm)

In order to even use this you need to buy a SEPARATE PRODUCT that it fits into. This is not mentioned ANYWHERE on the page as far as I can see. On it's own, it will not fit into a 52mm lens whatsoever.Do not buy this thinking it'll just slip into your camera lens. I wish the product page was more clear.

I have a few other bahtinov masks and they all seem to do the trick with the three star flares you align. This one has 5 that radiate out from the star like the traditional 5 pointed star we’ve seen hundreds of times in our life. The lines are pretty thick on this compared to the larger size masks and I suspect this is what causes the issue. Worked ok but not pinpoint on the prime lenses I used with it. You may want to skip this one a d just set your lens to infinity and zoom in on your cameras display to see how sharp it is.

At least the one I received did not fit my threaded filter as it was slightly too wide for 52mm filter. Pushed in but soon after it pops out and fall. Simply refused to stay in the filter. It will very clear I will lose it soon or later. I can not provide how useful for focusing as I returned it before using it. As it failed before use, I only give a single star.
