Cokin P system question

I searched it up on Google and watched some YouTube videos on it but couldn't find the answer.

Currently most of my wides are on cheap lenses where the front element moves and I was wondering how this affected the system, can you turn the filters freely? or do you have to loosen something first to rotate them? (planning to use grad filters for landscape type work)

I do have one wide where it doesn't rotate(28mm 2.5), so if need be I can get by with that before upgrading lenses.

The Cokin P filter holder can be rotated to however it's needed with out need for loosening anything. So a rotating front element will not effect it at all

Thanks!

Try focusing prior to adjusting the grad. This can prove nerve-wracking if you're focusing manually.

Thanks for the tip! That's what I do now with my CPL but most of the time it ends up turning the focusing ring so I have to refocus again afterwards. Which is fine with a CPL but when I stack ND filters it wont focus because it's not getting enough light.

So hopefully the Cokin kit will the cure, focus the lens adjust the holder and drop in the filters

If you haven't purchased the filter system, you might opt for the Z Pro instead, as it supports wider lenses. Then again, it depends on which camera you're shooting with: in a cropped-factor camera you might not see the benefit, but who knows? For the record, I've gotten vignetting from the filter holder (Z Pro) when shooting @ 17mm on a full frame camera; I can only imagine what I'd get with the P version.

Consider your purchase seriously. A filter system is a very good investment. These filters are not only for landscapes, I've used them in architectural photography to reduce the intensity of ceiling lights (1-stop soft-grad ND).

I'm on a crop body, but plan on upgrading to a 6D soon. But even then I'd be happy in the 28-35mm range, don't think I'll ever need UWA on FF.

I didn't even think to use them indoors! thanks for that tip, I mostly just need ND filters for video work and the gradual ones for landscapes.

Certainly for shooting stills if you have a lens with a rotating front, using back button focus can help. Get the focus sorted and then the motor will help to lock the front in position while you are adjusting the filter angle. If you are manual focusing you can flip the switch to AF to get the same effect, and of course you can also fire the shutter with the focus fixed.

Thanks for the tips!

Got the filter holder today, I had some ND8 filters that I purchased for my camcorder and luckily they fit the P system


I also placed an order for some HiTech ND gradients(or gradual) whatever you call them.

Gradual.

Thanks for clearing that up!

The actual term for GND's is graduated. Graduated netrual density

Also I have HiTech filter and they are not "neutral". They do give a magenta color cast.

Is the cast consistent that is easy enough to adjust out through presets with something like lightroom, or is it highly variable in intensity based on what you're shooting?

ah shoot, well if I don't like them I can just return them. Do you of any who don't have any color cast?


The ones I have now don't have any but I don't know the brand, they were just generics from amazon.


If it's easily fixable in post then no real problem(I have LR and PS)

The corrector stands corrected.
