Last night I was looking on Vimeo at GX7 videos to see what other people were producing. For the most part it all seemed very casual, not much good stuff in there. But then I came across this: First of all you should know that I've been shooting with my GX7 for almost a year now and I've messed around with the camera settings and resultant footage loads. So I pretty much know GX7 footage when I see it. The video above looks completely different to anything I've seen previously.I remember a phrase Andrew used in one of his videos regarding the BMPCC, "The camera has a very filmic response to mid-tones". And I guess this is the only phrase I can use to quantify what makes this footage look different. If you look at the tags on the video above you will see a mention of "Tiffen Ultra Contrast 5". So I did a little more research and it seems these things had their hayday a couple years ago around the time when the GH1/2 and Canon rebels were popular. These days some people still use them even for high end cameras like the RED. Here is the description from Tiffen itself: I quite like the look that diffuser filters give and it sounds like the Low Contrast filter will give some of that look along with the softened contrast. Does anyone here have any experience with these and can make recommendations?

I got in on the Blackmagic Pocket Cinema Camera (bmpcc) fire sale and in preperation for receiving my new camera I have been researching neutral density filters. What I would like to know is what are people's preferences between single ND filters and variable ND filters. And also your thoughts on IR filtration for the bmpcc. I already know if you go the "straight" variable ND route Tiffen seems to be a good trade off as far as quality and price. Dave Dugdale did an incredible review of "straight" variable ND filters. Honestly it is amazing it took an amateur like Dave to do such a test. I see so many posts on the internet from people who could have either saved themselves money or used a higher quality product had someone simply done what Dave did and test them out. These people are pros mind you! So the choice was simply, right? Wrong! I then came across another video showing IR (near infrared) issues with the BMCC... and other cameras including Alexa products. So there are numerous solutions. One could say the near IR pollution thing is nonsense and just get a "straight" Tiffen variable ND. Or you could go with a set of individual ND filters and skip the variable. You could also get an IR cut filter and use either single NDs or variable ND. Or you could get the Tiffen combined IRND variable filter. Or you could get the single IR ND filter sets. B&H has a strong three filter set for $164.50. Okay, that is a lot of options. The reason I posted is I want to know which one will give you the best results. I know the variable NDs have the polarization "issue." Sometimes I like using a polarizer on video so it isn't always an issue for me. Also there is a hack where by you turn the whole filter assembly en bloc to reduce or get rid of the polarization effect. I don't know how effective that is. This guy shows the "hack" to optimize the use of a variable ND filter... Here is a video showcasing the Tiffen IRND variable filter. So what should I do?

Hiya Guys! I'm new to this forum and will try to be as clear as possible. :) I'm about to buy new gear for videography pretty soon and have already chosen to go for the GH4, that i will use with these lenses : Voigtlander Nokton MF 35mm f/1.4 (77mm with crop factor), Nikkor 35mm DX (56mm with speedbooster), Nikkor 50mm FX (80mm with sb) and a Nikkor 18-55mm DX (28,8-88mm with sb). I applied a 2,2 crop factor for Voigtlander lenses and 1,6 for the Nikon ones (DX and FX). Is this correct? I keep seeing different crop factors all over the internet. The main use will be documentary and travel videography, so I'm trying to get good and sharp gear easy to travel with as I'll be shooting alone or with only one person. I've read several threads on the eoshd forum, reviews... and still have a few questions concerning ND filters. It seems like I should get a variable ND filter with a 77 or 82mm diameter. The max budget for the filters (one VND or filter system) would be 300/400 US dollars tops. - would you recommend a VND filter rather than a filter-system + ND filters for my use? - my Nokton diameter is 43mm, do you know if a step up ring 43-82 mm or 43-77mm exists? I couldn't find one over the internet. - if you faced this problem, did you find a solution? - would I get vignetting on corners with wide lenses even with the crop factor? - Reviews seem to highlight the Heliopan and Tiffen VND, are there massive pros for one rather than the other? I'm sorry for this long post! One question always seems to lead to another one... Thank you very much to those who will read and answer me :) And a huge thank you to all other posts and people in the forum for the previous topics that helped me. Woooo!

Just found this, nice demonstration. They are working on making 4K version available.

In my quest to find the perfect matte box, I have been doing some research that I will share here in the hope that someone else may benefit from it (this is a cross-post, there is also a thread on Personal-View: [url="http://www.personal-view.com/talks/discussion/2876/matte-boxes-and-filter-thickness/p1"]http://www.personal-...er-thickness/p1[/url]). Not all matte boxes on the market will take Tiffen or Schneider filters. Take for instance the DMatte from DFocus. It's a bargain for the price, but when I finally brought one home, I couldn't support my Schneider filters because they were a millimeter too thick. I've since returned it and resumed my search. It looks like these are my options at this point:[list] [*]Arri (confirmed by forum member) [*]Chrosziel (personal test) [*]LockCircle (manufacturer confirmed) [*]Lanparte (confirmed by forum member) [*]Cavision (personal test) [*]Cinematics (confirmed by forum member) [*]Cokin (website info) [*]Vocas (manufacturer confirmed) [*]Genus (manufacturer confirmed) [*]Movcam (manufacturer confirmed) [*]Century Optics ["Sunshade Filter Holder"] (confirmed by forum member) [/list] I have no confirmation, but I'd be surprised if the matte boxes from O'Connor, Bright Tangerine and TLS Raven could not hold 4mm filters. If you know of any others, please comment and I will update the list.
