UV Filter Differences? Hoya / Tiffen / B+W

O.K. I've searched and read what I can, but I'm still totally confused.

I purchased a Tiffen 72uvp filter when I bought my camera. It's a $27 filter.

After reading around it seems that everyone (or a lot of you) are using the Hoya Pro 1 (S-HMC) Super Multi-Coated Glass UV filter. This thing sells for $80

What is "super Multi-Coated", do I need it? I shoot 90% out doors live action, and will be going to Kauai for two weeks to film lots of nature scenes.

I've also noticed that some of them (B+W [never heard of em til today]) get very expensive.

Should I upgrade to the Hoya? and of course WHY?

Thanks a bunch guys, I'm trying to get dialed in before my trip in ten days.

The Glass has coats of UV protection on both sides.  It acts as a lens protector and also reduces UV light.  It is highly reccomended.

I have the HMC82SKY and paid $44.00

The Sky gives a little warmth to the bluish cast on EXT shooting.   (You don't have to get the Sky of course)

Hi!
I have the HOYA Skylight 1B Both sides coated. It costs 29 Euros. As I said in post the other day I'm not sure if it's good enough, especially when shooting against a light because it seems to get diffused.
Don't you also hace problems when ataching the lens cap? Don't you think the cap touches the lens?

I know that it protects and reduces UV....

I have a cheapy Tiffen on there right now. I'm curious as to what the real difference is between the Pro1 and the Tiffen I have.

Is there a real performance difference??? Or is it just hype??? I was always under the impression that a UV filter was a UV filter.

Keep in mind I'm a total rookie and used to have a DCRPC100 with a set of $10 filters.

Thanks for the info? I definately don't want a filter/lens where the cap doesn't fit well
 
Re: UV Filter Differences? Hoya / Tiffen / B+W

The most relevant difference between protective filters is the type of coating that is applied to the surfaces of the filters (other differences could include the type of glass used and the construction of the filter ring). The coatings on the filters reduce reflections and therefore increase light transmission. Straight glass reflects about 4% of the light per surface (i.e. 8% for a piece of glass), and these AR coatings reduce that. You can see the difference by looking at the reflection of a light source in filters with and without coatings. All of the lens elements inside your DVX are coated to reduce these unwanted reflections as much as possible.

Filters can be purchased that have no coatings, a single layer coating, and multi-layer coatings. Multi-layer coatings reduce reflections the most and are also the most expensive. They are also more sensitive to damage than the bare glass. Different companies have different techniques for reducing reflections and thus you have the variety of choices and costs.

What you stick in front of your lens is entirely up to you, but if protection is your aim, you probably want it to affect the image as little as possible, and thus a good multi-coated (MC) filter is best. In my experience Hoya's S-HMC filters are among the best, particularly for the cost. B+W and Heliopan are also excellent, but you pay more for the brass rings and German engineering. Some camera manufacturer filters (e.g. Nikon, Pentax) are also worth considering, though there is usually a premium for the brand. I'm not familiar with the Tiffen line, but I suspect that for the price you mentioned they are not multicoated. I think it's worth it to have a good MC filter in front of my DVX, but only you can make the decision for your needs.

EXCELLENT INFO!

Thank you for taking the time to clear that up for me. I think I'm going to go with the B+W as I've heard several people complain about the Hoya and lens caps.

Thanks again!
 
Re: UV Filter Differences? Hoya / Tiffen / B+W

B+W is great. They tend to have thicker rings than most, so you'll need to check vignetting or spend even more on a thinner version. I would guess that the regular version should be fine, but have no direct experience on a DVX.

For what it's worth, I use a Hoya S-HMC on mine and have no problem with the lens cap. Is it possible that you are getting info on the Hoya polarizing filers? The S-HMC version of those don't have front filter threads and so you need a different style of lens cap.

Quite possibly, I believe the filter that I read about was the "sky" filter.

I asked a local guy that I trust and he uses the Hoya SHMC Pro1 on his VX, he said it works great and for the money it really can't be beat, so with that along with all the positive things I've read I went for it... there just seems to be one guy that's unhappy with the "sky" filter (I couldn't find it anyway).
