1/4
Match the diameter (e.g. Ø49mm) on your lens to the filter size. This is different to focal length.
2/4
Align the filter with the lens and thread by rotating clockwise. Avoid overtightening.
3/4
To compensate for the 1 to 8.66 f-stop darkening of your image, slow your shutter speed for motion blur effects. Or, you can adjust for the darkening by opening up your aperture, which creates a shallower depth of field. You can also combine both exposure setting adjustments.
4/4
Use our ND2-400 to create more cinematic effects when filming. By blocking 1 to 8.66 f-stops of light, you can open your aperture for a shallower depth of field, creating stunning cinematic effects in different and changing light conditions.
Love their gear and the customer service is world class.
I love the compact design for the 3 filters. It's super easy to switch out. Works well with my Ricoh GRIII convertor.
I had a problem.....
I use an 82mm lens on my camera.
I also like to use a mini matte box for outside video.
Most adjustable NDL filters do not fit inside the matte box on the pass through ring.
But........
These awesome adjustable NDL filters from URTH do....
And.....the CPL filter will go on as well and I can leave the very nice UV filter on to protect the lens!
If all that wasnt enough, the whole stack screw together and come with two screw on caps, one for either end to protect them whilst they are in your box or bag.
This whole kit is very well thought out, well designed and well built.
Well, well, finally a solution for photo and video warriors to take with them without having to take all the extra bags. You can stick this stack in your pocket.
A UV, CPL, an adjustable NDL with hard stops and protective screw on caps?
Sold.
To me, after looking for ages across every sales platform for a solution.
The one and only Exploret Filter kits, from URTH.
Oh, and they fit on the lens in the mini matte box pro (Smallrig version with an 82mm lens).
The images are tip top too.
Not a pixel peeper but my images are awesome, I hope yours will be too.
Finally the cost. Gotta say, for the money this kit is a steal.
So if you're in the market, this is a great solution to shooting out doors in daylight.
Try it. You can thank me later. 🙂
Oh wow... I don't even have words. It is beyond fantastic, the crystal clear clarity and the hybrid features of being able to screw them into each other so you don't have 383952 lenses floating around in your camera bag. The ND filter has absolutely ZERO cross.
Cannot recommend this enough! Without a doubt worth every cent!
