Question about filters

Hi Everyone,

I am wondering if this is a good deal and if it is compatible for Pentax lenses? A 52mm filter should fit any 52mm lens diameter shouldn't it? Also, is this a good deal?

Thanks,

Filters are sized by the size of the filter threads on the front of the lens. So these will fit any lens with 52mm filter threads. So whether it works or not depends on which lens you have, not all Pentax lenses are 52mm.

As to value? Who knows. Hoya has a fair reputation in that market, but like most manufacturers they offer a range of products both premium and value. These are certainly not the Hoya top of the line. Their higher end lines cost as much or more just for the CPL. Depends on your use and budget whether it is appropriate for you.

I would not count on these being too high-quality. The UV is essentially useless except in conditions such a tractor pulls where you are in the line of flying debris.

The ND8 can be used if you like smooth water effects. CPL may be useful, but I don't use any of them and particularly dislike unnaturally dark sky,

the UV filter is the cheaper one UV(C) instead of UV(0) but will work just fine.

and yes, the threading is always the same, so all 52mm filters will fit a 52mm filter thread on your lens.

CPL is very useful when shooting in sunlit conditions and don't want the glare from water. Or when you don't want reflections from glass etc. same reasons you would wear polarized sunglasses in other words but since the camera will compensate and gather more light, you will not get darker pictures but you will get a few other changes like: boosts colors, greener grass, bluer sky. It is very useful to get higher contrast between sky and clouds when shooting B/W. Reflections from metallic surfaces will remain the same since that is not polarized reflections.

The ND8 filter will reduce the amount of light with 3 F-stops. That means to get the same exposure as F2.8 and 1/1200 shutter you would need F2.8 and 1/150 second. The info stated above regarding smooth water effetcs is usually achieved with more light reduction than 3 F-stops. you usually want exposures at a few seconds.

And in a pinch, a CPL can do double duty as a (mild) ND filter.

That is very true, your average CPL filter will reduce the light with something between 1 and 2 stops.
