Yes
I've used the search function but just way to many threads rear there ugly head.

I'm about to pick up a circular polarising filter for my camera & I've seen the 'normal' Hoya filters but also I've seen a HRT polariser is there any real advantage with these (I have UV filters on both lenses already)?

Thanks.

Not for a CPL its not.

Any decent brand will do the job well, I havent heard much about the HRT, I believe they let a bit more light through.
I'd just get the best Hoya you can afford. I used the PRO-1 which was nice.
Take the UV's off before you use it though.
 
Agree with Tom. I have Hoya Pro 1 77mm Cir.Pol. which I use which has the 'thin frame' to cut down vignetting on ultra wide angles, and don't stack with a UV filter already on.

I also use Lee Filter Foundation kit for the grads and 10 stopper, but haven't yet felt the need to have a slot-in polariser at the moment.

If you go for a screw in filter....think about buying the biggest size you are going to use. Typically this will be a 77mm size, so even if you don't have such a lens right now consider if it will be a future purchase. You can also buy stepup rings to attach this bigger filter to your 'smaller' lenses.
 
I wouldnt. It'll vignette like a b****r and probably cause all sorts of flare.
If it were me I'd bin the UV's altogether, buts thats a whole diferent subject.

Why is this chaps please?

And what about a plain protector, can you stack a CPL with one of those?

Every filter on the end of the lens is an extended tube for the lens to look down. Especially with wide angle end of lenses, you'll find that the corners of the frame become darkened -"Vignetting"

Also every layer of glass on the front of the lens has the potential to reflect some light about - so you can get double images or lens flare.
 
Although I suggested going for a 77mm filter, they are more expensive than smaller diameter ones. If you only have 2 52mm lenses.....it could be worthwhile just going for that. If you have any inclinations of another lens sometime soon, just consider buying for the biggest filter size then stepup. Its your call of course, you could have a filter on each lens if you had the cash.

There a few threads on UV filters and Protector filters. Definately don't stack as mentioned earlier. They will physically stack, but don't bother - or try it and see for yourself.

Should you ditch UV filters? I hate to point out searching for that answer, but this is often asked, the opinions are divided and the thread usually ends up with multiple points of view and you won't really be any wiser. Only your personal experience can actually convince you, you may scratch the lens, you may believe the image degredation caused by filter is too much or neither may happen.

Regarding the filter kit, I haven't used it myself. On a similar note, if you ever go for a wide angle, sometimes used to great effect in landscapes the Z-Pro might be a better future proof purchase. Bigger filters and more expensive again I think.

Sorry these answer skip around a bit, but I started off with 58mm lenses and now have 77mm filters and 77mmSlotIn Filter adaptor rings.
 
Don't bother with uv filters unless u wanna protect the lens they don't do a great deal for the image

Decided to pick up a Hoya CPL filter but now find there are several types, the Hoya 52mm HD Digital Multi-Coated Circular polarising Filter or the Hoya 52mm Pro 1 Digital Multi-Coated Circular Polarising Filter.

Is there a big difference between these two?

Also has anyone used the store in the above links, I ask as there prices just seem unbelievably low compared to other stores.

Yes, there is a big difference between those two. The HD is the better filter, being about half a stop lighter in overall density and having better water-resistant coatings, amongst other smaller details. They both polarise the same, both good.
