Key Features
- Drop-In Circular Polarizer Filter
- Fits Sony FE 400mm f/2.8 GM OSS Lens
- Helps to Eliminate Reflections and Glare
- Reduces Haze in Landscapes
This Sony Drop-In Circular Polarizing Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. It is made specifically to fit within the accessory filter slot of the Sony FE 400mm f/2.8 GM OSS Lens, whose front diameter is too large to accommodate a screw-on filter. With that lens, the effect of this filter occurs behind the main glass elements instead of in front of them.

How many stops of light do we lose by using this polarizer?
Like all circular polarizing filters, the loss of light varies with the angle the polarizer is applied against the angle of the light source. I do not know what the maximum light loss would be but see the other answer for a guide to this. The minimum light loss should be close to zero.

There is no variable nd filter that works the same way for this lens ?
A polarizing filter must be turned and this expensive support does that. A ND filter does not need to be turned. Therefore the clear filter that comes already in the lens can be replaced by any 40.5mm filter into the non-turning drop-in frame that comes in the lens. Just purchase a 40.5mm ND filter, screw out the clear filter and screw in the ND filter then drop the frame back into the lens. Standard 40.5mm diameter screw thread.

Does this fit in the new 300mm f2.8 Sony lens?
This filter fits all the FE super telephoto lenses. The older A-mount lenses used a larger diameter filter so are not compatible.

Re: 600mm f4, What if I don't want to use polarizer, can glass be removed and insert holder only?
No. The Sony Drop-In Circular Polarizing Filter for Sony FE 400mm f/2.8 GM OSS Lens has a non-removable glass element. The filter tray included with the Sony FE 600mm f/4 GM OSS Lens is compatible with 40.5mm filters and can be left empty, but is not compatible with circular polarizers due to it lacking the external dial.

does this filter come with any type of storage case?
It comes in a round, plastic case that just fits into the provided slot in the packing of the case of the FE 400 F28 lens.
It works and is unique but it is grossly overpriced.
