What Urth doesn't say about their ND filters

- Опубликовано: 26 июл 2024
- If you need an ND filter for your camera, here's something you SHOULD know before you buy one from Urth. I also unbox the ND 64 and provide comparisons between a variable and the 'prime' filter. (Urth provided me some surprising information when I contacted them regarding the vignetting issue on one of their variable ND filters). Basically, Urth is not providing information on their website that they should about their filters, and I go over what that is and how I learned about it.

This is the product. Great product, but double-check with Urth that it suits your lens!

I don't think it's that hard to understand that they can guarantee the compatibility of the fixed ND filter with your setup because it is literally compatible with any lens ever created (with that size of filter thread), unlike a variable ND filter. That's because the working principle of a variable ND and a fixed ND are very different. Fixed NDs will always work.
It's not about understanding. It's about the statements being made. It's definitely very easy to understand that they can guarantee compatibility, particularly with a fixed ND. It's weird how they are going about explaining the compatibility or incompatibility with their products.
ciao! the topic about the noise is interesting. could you create a drive folder with the raw files?
Hey! I'll see if I can find the files!
I found the photos :) See if you can access them here - drive.google.com/drive/folders/1qaVWqZ_TyfTa9O-TUCBZA3j51sADzo1i?usp=share_link
@@NitpickersAnonymous Ciao John, thank you. I have watched the files and I noticed that all these pictures are taken with 1/320 f2.8. The problem here is that are taken with different iso values: 160 5000 8000 12800. That's the point.
Nd Filters are created to help photographers achieve creative pictures using long exposure even under the sun without close to f22 and help the videomakers to use their lenses wide open ex 1.8 - 2.8 at 1/50 or 1/60 or 1/100 or 1/120 (and more).
In your case, the noise is generated because the ISO is higher to take a good exposure with the same Exposure time and the same aperture used without ND.
I saw you are from Australia,,, try to go to the beach or near some beautiful city street where a lot of cars are moving, then set the camera with ISO 100 - F5.6-8 and if you can 20-30 seconds of exposure with the ND filter.
I hope this suggestion will help you enjoy using ND filters :).
Cheers from Milan.
That is correct! I had different ISO values to combat the ND filter values. I was already aware of the noise being caused by my ISO values 😁 I love using my ND for fun things like that! Thanks for your tip!
@@NitpickersAnonymous 😀
Was considering urth variable nd but i guess i’ll buy the peter mckinnon variable nd now 🤔
Yeah could be worth if you don’t feel like asking Urth what’ll be compatible with your lens or ‘risking’ it, so to speak
@@NitpickersAnonymous agree!
I’ve heard a lot of bad stuff with then PPPMK in terms of color shift and vinetting.
@@LCreeper575 yeah rumors of the vignetting are highly likely true that you’ve heard
Hi, just need to comment on that one. The darkened corners/ cross effect/ the vignetting in your pictures at the end of the video is the result of two polarizing filters being in a 90 degree angle to each other. Since two stacked polarizers are the way that variable ND filters are working, it’s a problem that will occur on any VND, if you turn them far enough. The effect appears way stronger on wide angle lenses, since their angle of view is often even wider than 90 degrees.
The solution to that problem can be filters with a smaller range (f.e. 2-5 stops; 6-9 stops), because they can’t be turned „too far“, but even with them a really wide lens can always lead to problems in usage with a VND.
Please just don’t let any salesman tell you, that their specific filter won’t cause these problems, since it’s physics - not quality. So in conclusion, if you got a wide lens, a fixed ND filter is always the better choice :)
6:24 Maybe that's what they have in the shop?
What are you saying?
@@NitpickersAnonymous you were wondering how Urth knew the filter would work a specific camera/lens. I just was just suggesting, maybe because that was what they had in the shop to do the test. :) Thanks for your review though, because it helped me to make a purchase w/ them.
Sorry for my late reply btw! Perhaps it was, but then why would they ask me as if they went off to check if it works (which I believe they said their techs did do). 🤔 🫤 but I’m glad it helped you in some way!
