Dronexpert gimbal for Phantom Vision

White, as I said in the earlier post, the gimbal will work fine with up to a 100 grams, as I sat a 100g weight on the cam, and it lifted it..the filter holder and uv filter I have on there now weigh in at 17.7 grams, and it works flawlessly. the heli has given me over 100 flights with no issues, but, I have never taken it out of "vision" mode..no reason to. if I wanted a sport quad, I would have bought one. I also feel the DE gimbal was worth the $$, as it is a nicely thought out piece, and does what its supposed to do.
 
strange, I wonder why it wont hold filter up ( I have the same one from DJI) . . . the camera just droops down when the filter is on it. I might try it the way you have it and see how it works by gluing it to the body of the FC200.
Thanks for the reply.

White, I see no speed difference either, with or without the filter..and the legs on the holder are not very heavy, as the whole thing was 12 grams..cant weigh them, as I machined them off, nothing left but aluminum shavings..
 
Great, so maybe the Dronexpert can hold a filter. However, can anyone show a difference that a filter really makes in quality? I am really suspect how much of a difference it would make using a cheap lightweight filter and offset what you would lose with quality from cheap glass vs any improvements by the filter itself? Since the camera is not really high quality, adding a lower quality glass on top of it, is suspect in improvements if any at all?
 
Only filter that would be worth putting on it would be a cpol. All other filters can be added via software with the same effects. That being said, I am not sure who makes the lens inside the camera but if you have a lot of sun glare then yes a cpol would help. Other then that, use software to do what you want.

That's not true. You cannot simulate the effect that an ND filter has on the video in post.

But fot the most part, the circular polarizer would have same effect as a ND only it can reduce glares also if set right. NDs can have too much darkening which can cause a blur effect if it is overly dark, thus the circ polarizer has a reduced darkening. Although the filters may have a benifit, it is still extra glass to reduce photo or video quality, expecially using the cheapo glasses of most filters. Would like to see a side by side comparison for real determination still. I no longer use any filters on my land camera any longer, other than special effect circumstances, to retain maximum quality. If real improvement is realized, then
I use one and mostly circ polarizer and infrequent ND, but very high quality of those. My ND actually has combo circulat polarizer and Adjustable ND strenghts.
 
I still don't understand why people in here seems to bee so hooked on filters for the PV2.

I'm also sure a lot of the people don't even know what the filters are doing, but have just read about the hype of the filters in here.

I have been writing this before but I do it again :D \

Don't think you can get a cheap noisy and blurry camera to produce better quality with a filter, it can only (in most cases) be worse.
 
I posted a very short video clip which, apart from the flaring for which I have the sticker cure coming, showed even a cheap circular polarizer produced reflection-free water and some good contrasty clouds (they "pop" nicely) even at a non-optimal angle to the sun... http://www.youtube.com/watch?v=lcCKkUy7F80 I think it shows some promise for using a CP compared to stock. Once I've got my matte sticker from http://www.signsoflife.net/phantom-bezel.php I'm going to do more testing when the sun makes a reappearance and I don't have the halo flaring going on...

Pull up please can you explain flaring, I had a short flight on Sunday and when moving forward against the sun had horizontal lines flashing across the screen?
I've just made a sticker for the lens, I have matt vinyl however it has a slight sheen so I printed it so there's no sheen at all, need to test but never seem to get the time to get out much these days.

The advantage of an ND filter for the PV2 is this:

1. Someone buys a poorly designed gimbal for their Vision
2. This gimbal mounts at the ends of the legs
3. Because it's mounted at the ends of the legs any vibrations from the motors and/or props are accentuated
4. Many people have jello aka rolling shutter issues
5. Adding an ND filter slows the shutter speed and virtually eliminates the rolling shutter
6. A side benefit is that there may be fewer blown highlights

Soryy but that is NOT correct. You are talking about Video, and the Video have a fixed frame per second like 30fps or 60fps so the filter will not change the shutter time!
And for Photography, the faster shutter you can get the better!

That's caused by prop shadows striking the lens.

Thank you for your reply Quadzilla
 
QuadZilla. I can't tell if your theory is right or not, but I have been testing this gimbal and when shooting at higher fps (60 vs 30) the jello effect is less perceptible than when doing so at 30fps. The fact is that you can choose between fps (frames per second) when shooting video, but shooter speed is performed automatic by camera when it is recording video.

Klaus, you don't know what you're going on about.

Frames per second and shutter speed are two different things. Learn here: http://www.mediacollege.com/video/camer ... s-fps.html

Again, an ND filter limits the amount of light reaching the sensor. The Vision or a GoPro are fixed aperture cameras so the shutter speed is slowed down (regardless of the FPS, see above again). The slower shutter speed limits jello.

Seeing is believing (this is a gopro but the same principle applies - and he also has his camera attached to the legs like the dronexpert setup):

Again, you're confused. Claiming that a faster shutter speed is always better is incredibly simplistic and fails to account for the relation between available light, aperture, desired depth of field, ISO, etc. etc.

For example, when I am panning and want to make a photo with motion blur "the faster the shutter you can get the better!" makes no sense.
 
Not sure about others, but got a bill from FedEx from my shipment for $18.22 for Customs Duty fees. Just making anyone aware to figure this in with the costs that may not be expected. Just making aware to insure you plan on it if ordered as well as other products also from other gimbal suppliers also if ordered from overseas.

Not real happy at this moment. I received a bill from FedEx a little bit ago for $18.28 for Duties, taxes and other fees. I ordered with shipping included and now got this bill. Will ask DronExpert about this but wondering if others got same? It's not a lot, but still, my order was shipping included, so thought this should have been included. Will await to see what they say, but kinda chas my rear that this bill came without any warning or expectation.

Hi Dastagg, I'm not sure but could it be an import tax?
I'm in Ireland and looking at maybe buying the rotorpixel gimbal because I'm not liking the jello on all the videos I've seen so far from the dronexpert gimbal.
Anyways... If I do buy the rotorpixel from Canada I'm expecting to pay their advertised price + shipping and then normally when you buy something from outside Europe I'll be expecting a bill from the shipping company for the import tax which im sure will be a lot more than what you paid. The shipping company wont give me my goods until I pay the duties.

It's not a theory let alone my theory.

There are three ways to eliminate jello in bright conditions:

1. Shoot 60fps vs. 30fps
2. Shoot 30fps with an ND or CP filter
3. Shoot 60fps with an ND or CP filter

Ok. Then If I add the filter it could help me solve my hello problem specially at 30fps?

Quadzilla, if I may, which ND filter do you suggest? ND2? ND4? ND8? Higher?

Maybe I am being unreasonable, however, shipping was supposed to be included in my final price. Bill shows customs duty. I wrote them and am going to pay the bill, but was a definate suprise and disapointment that it wasn't included or advised of such charges prior to order placement. I do understand the reason for the charges, just thought my payment for product with paid shipping included would have included this. Still like the gimbal, just a little disapointed it wasn't communicated prior to shipment.

Thanks however and not going to down Dronexpert until I get their reply and maybe I should have waited for their responce prior to posting but haven't heard others as of yet having an issue and maybe no one else has an issue with this. I will advise of a positive or negative responce from them here as I know more. So far, they have been most responsive to any messages.

Import/customs duties are levied by your government on items you import. International sellers can't add that into the cost because a) it's not applied by the government of the exporting company's country, and b) rates of import/customs duty vary country by country, and then further vary depending on the type of goods.

Most jurisdictions will apply a minimum value for goods below which they won't worry about collecting duty as the admin involved outweighs the income. I've found that state postal services are far looser at collection than the large carriers like FedEx, UPS, DHL, etc who seem to collect duties owed without fail. Given an option I try and opt for a standard postal service if possible on higher ticket items for this reason (although at this level of spend you'd probably always get hit with the duty as the value is high).

Thanks for clarification and I did some editing to my posts to be sure to negate any adverse impact to the company, as Again, I am well satisfied with gimbal and their company. Sure don't want to relay any bad rap on them for something they cannot control. Hope I didn't leave impression of any negative impact. They have been most cooperative in their services.
