Re: UV protective lens
you betcha.. get multi-coated.. must be multi-coated. Hoya, B+W makes some good ones. Tiffen doesnt make a multi-coated lens (even though they say they do) so if its tiffen its not multi-coated.

Re: UV protective lens
I saw a very interesting study at dpreview.com where they analyzed image quality based on having a clear filter on your lens vs. nothing at all. Very surprisingly, even the best clear/uv filter affected the image sharpness. This was in regards to digital SLR photography but I think it probably holds true for digital video.
Based on this, I have stopped shooting with clear filters, even good ones, on my lenses... I keep them on for traveling, etc but then take them off when it is time to shoot.
We'll see...

Re: UV protective lens
Hmmm, I'm looking at this Canadian site and I see 3 different UV filters.
http://www.cameracanada.com/eNet-cart/Default.asp?cat=FIL&type=2&mkt=&brand=Hoya
UV Guard Filter
UV Multicoated Filter
UV SUPER Multicoated Filter
I guess the first one isn't multicoated?
Also, I think (by looking at the prices) the B+W are better. Anyone have any comments?
I ask because, I'm thinking of sticking with a specific company for all my filter solutions.

Re: UV protective lens
If it doesnt say MC or multicoated it probally isnt
And B+W may be fractioaly better than Hoya.

Ditto. I view the UV filter as primarily a transparent lens cap, and remove it when shooting something that has to look good, unless it's a dangerous/wet situation, etc. In other words, the UV filter stays on about 90% of the time, and comes off for the 10% that the camera is actually shooting.

Re: UV protective lens
If you want 16:9, you definitely want the anamorphic adapter, its benefits far outweigh any minuses. If your budget can afford it, the anamorphic will let you get the best 16:9 footage possible from an under-$10,000 camera.

Re: UV protective lens
I'll ask another question on this thread about filters.
Let's say that I buy a circular filter (or serveral), then what happens to the factory matte box that came with the camera? Can I attach it on top of the installed filter? Assuming that the all of the circular filters are threaded in the front so that multiple filters can be attached on top of each other.
Better yet, what about the Panasonic 16:9 anamorphic adapter. If I use that, then the wouldn't the order of lens/filter arangement would have to be:
anamorphic adapter -> filter(s) -> DVX lens -> CCD
Does this cause problems? Shouldn't the light rays hit the filters BEFORE the anamorphic adapter?

Re: UV protective lens
the screw in filters dont affect the bayonet mattebox that comes with the camera, they mount on two different mounts.
As for filters, you cannot put anything between the ana adapter and the lens, the distance has to be perfect. To use filters with the ana adapter you need to put them in front of the ana adapter.

Re: UV protective lens
I'm puzzled.
I thought that the whole problem of the Pansonic anamorphic adapter was the mini matte box in front that prevent it from attaching any other filters/matte boxes on it.
I guess from what you are saying, filters can be attached in front of the anamorphic adapter.

Re: UV protective lens
Not circular filters. You could fit 4x4 or 6x6 filters (with an appropriate filter holder or matte box that works around the anamorphic adapter).

Re: UV protective lens
Woah,
I'm was almost screwed there. I was about to buy some circular filters.
So, if I'd have bought them, I could not have been able to use them with the Anamorphic adapter.
But, the other problem I guess is that there arn't any Matte box that will fit onto the anamorphic adapter -- say, for the $1200 system by chroziel.
Does anyone have a clue why Pansonic "superglued" the mini matte box on top of their anamorphic adapter? It sure puzzles me that a company that make a pro minded product like the DVX would append their product with a consumer type of adapter.

Re: UV protective lens
chroziel isnt the only one.. we used an arri 6x6 that worked well infront of the anamorphic adapter. Problem with that is it gets really expensive.. as your paying 500 bucks for each filter you put in front of it (6x6's)
And the adapter I can't agree with you more. The actual entire thing is plastic.. and we actually cracked it the first day we used it. Total piece of garbage... but it does take nice images.

Re: UV protective lens
I guess the next question is...
Weather Century Optics, or some other Lens company, is going to release a proper anamorphic adapter.
Is this a more of a question of when than would?
I would love it if they released a version by next month, but something tells me I shouldn't hold my breath.
Adam Wilt talks about Optex adapter here:
http://www.adamwilt.com/24p/index.html#16x9
He mentions that you get vignettes in the widest shots, but my question would be weather you could attach circular filters/matte boxes in front of them?

Re: UV protective lens
Century is developing an adapter. At one point quite a while ago, they mentioned that the price may be in the $2,000 range. I don't know if that's still accurate.
A proper mattebox is the way to go. Other filtering solutions have been demonstrated as well -- some people clip 4x4 filters into the inside edge of the adapter's lens shade, someone else adapted a Cokin X-Pro filter holder to the anamorphic (but that means you have to use Cokin filters...) and someone posted pictures and instructions on this board about how to cut a slit in the adapter's lens shade, so you can slide 4x4 filters right into it at no additional expense. So there are low/no-cost options, but the proper way to do it would be to get a matte box that's designed to support the anamorphic adapter.

Re: UV protective lens
dont do the cokin route... cokin filters really arn't the best, and as barry said its best to do it right, your gonna be payng some money. Slit in the anamophic works, but only gives you a single stage option, and leaves the front of the element open to all sorts of flares.
Cinetactics matteblox's flags work on the anamorpic adapter, you just put velcro on your anamorphic lens, and it works rather well. They tell me they are producing an entire filter/matteblox system for the anamorphic that will be under $200.

Re: UV protective lens
For me, the timing is really key. I need the adapter in the next month or two at the latest.
However, being a Canadian $2000 would mean that I'd be paying upwards of 3k in Canadian, which is more than half the cost of the camera. That's pretty scary, so I am leaning against the Pansonic solution, albeit an expensive plastic.
But what is really wrong with cokin? I know some people actually recommend them.
In any event, if I am to go the Pansonic anamorphic rout, I guess I can't buy any of those circular filters.
To me it's logical to make a product that allow multiple threaded filters to be connected before the anamorphic adapter is connected, but I guess someone was quite drunk when they were designing it.
Does anyone have some closeups of the Pansonic Anamorphic lens? Especially the threaded portion where it connects to the front of the camera. I would like to know how exactly connect to the camera

Re: UV protective lens
If you need it that soon, the ONLY option is the Panasonic. Makes your decision pretty easy, actually! ;D
For pictures of the anamorphic adapter, check out:
http://www.biz-max.net/bizmax/ag-la2700.htm
As far as Cokin filters -- they're made of a resin that is not as optically clear as high-quality glass filters. Cokins are very inexpensive -- for a reason. If you're satisfied with the image quality, then they can be a great deal. But high-end users don't typically use Cokins, they're more of a budget system.
