I mounted the kit on a lens with the 72 mm ring and it fits perfectly. It's easy to assemble and its operation is very simple, it doesn't require reading the instructions (I'd say it's better not to read them) just seeing the illustrations is enough. As for the quality of the product, it seems to be made with good materials and the finish is excellent; the polarizing filter holder is very effective, placing the filter well and with care and you don't touch it at all. There are two compartments for the square filters that I hope to get the most out of, I'm happy.
As for the optical quality of the filters, I can't comment because I haven't used them yet.

You can also use the hood with this adapter with NEW non-locking FD mount lenses. After attaching the lens to the adapter, if you turn the LOCK-OPEN ring on the adapter to LOCK, the aperture stop will move in accordance with the aperture ring on the lens. The same applies to FD mount lenses, which have a locking mechanism. It is therefore an adapter that can be used with aperture both for FD and NEW FD whether there is a locking mechanism or not.

Love the purple color! Easily put together! Very easy to operate and light! New toy for mom very much appreciated!

robust and efficient ring even when mounted on the machine, aesthetically very nice, with orange finish detail. Above. I restored all old quarters.

The set comes in a bag.

The filters are well made, the filter glass is immaculate and the magnetic ring is clean. The 3 filters can be changed quickly thanks to a 77mm magnetic ring, the ring can also be easily combined with an adapter so that the filters can be mounted on the lens.

The optical performance of the filters is good and there is nothing to complain about, the ND filter is essential for photography and is therefore almost always mounted on my camera.

The filters are of excellent quality, leaving the adapter ring mounted, when needed they can be inserted in a second. The filter case is also excellent. I will also purchase the ND64 filter not present in the kit, but I am waiting for a discount.

It fits perfectly. This NEW design looks great on the camera body. Beautifully engineered. Works as it should. Perfect for some Vintage Glass
