LEE Filters G4 reviews

Side Guides for 4mm Thick Filters is rated 4.2 out of 5 by 11.
Rated 3 out of 5 by from Guide pegs didn't line up with those on The lee filter holder kit rails have pegs and holes that make it easier to align multiple rails on each side. The pegs and holes on these new rails didn't quite line up with those on my existing kit. The screw holes line up, just not the guide pegs. I ended up cutting off the pegs and enlarging the holes. This adjustment wasn't difficult, but it shouldn't have been necessary.

Rated 4 out of 5 by from This is an expansion accessories This is an 'expansion' accessories; it does not come with its own end plates. You have to use back the existing end plates or stack it in addition to the existing rails. I have a standard Lee filters 2mm-rail foundation holder. I would like to replace the rails with this 4mm so that it can take Schneider glass filter, while the 2mm rails will be used for some other custom-made holder for the continual use of 2mm resin filters. However, as this rail does not come with end plates, I have to use back the existing end plates. For the custom-made holder, I stacked two 2mm rails together so that the top rail can act as the end plate but I can't practically use it as it caused vignetting to my frequent used wide angle lenses.

Rated 3 out of 5 by from Works but not a perfect fit I bought this to use with a 4mm thick ND filter. In short, it screws in and holds the filters fine but it doesn't line up 100% correctly with the 2mm filters that come with the Lee Foundation Kit. These 4mm rails are a bit shorter than the 2mm rails and so the nubs have trouble locking multiple rails in place. I found that the 4mm rails only fit if you stack it on top (the furthest rail from the lens).

Rated 5 out of 5 by from works great, excellent fit Don't listen to the other review's here. These fit perfectly without any modifications. You just have to make sure you use the existing lower spacers that came with the lee filter holder. You can mix it up have 2 x 4mm rails or a 2mm and 4mm rail. Still no vignetting with the Canon 16-35mm F2.8 L II on FF body.

Rated 5 out of 5 by from Exactly What I Needed The LEE Filters System is GREAT but, I had some existing 4mm thick filters I wanted to use with it. Bought this, popped them on, and presto. Done. Perfect.

Rated 4 out of 5 by from Well made, but slightly larger than other parts Like the whole LEE system, these are well built and hold 4mm filters nicely. Not too snug, not too loose. However, like other reviewers here I found the size to be slightly different than my other LEE filter guides. My other parts, the spacers and 2mm guides, are slightly shorter than this 4mm guide. The plastic wholes and bumps/nubs don't align well enough. Without modification there would be one end bending up. I took a razor blade and drill to my parts to make them sit happily. My guess is that the manufacture of these small parts have varied slightly over time. I bought my LEE system used and I suspect it is older. That's not an excuse, though. Such measurements shouldn't change and these tolerances are not too hard to maintain.

Rated 4 out of 5 by from They work! These spacers are required for certain thicker filters such as the Cavision glass ones. They are easily installed into the Lee filter holder. The installation info on the Lee web site is helpful. You will probably want the 4mm slot closest to the lens but other options are possible. They work very well once installed.

Rated 5 out of 5 by from Works as Advertised What can you say about filter guides from Lee except they work as promised. these are needed if you plan on adding a square polarizer to your filter armada.
