Monopods and UV protection filters, at 8 € and 25 €.
One coating layer per side, said out loud
Two in total, counted, on a 49 mm filter with a 3.4 mm frame published. That is the lowest coating count on its shelf, and a maker that publishes the low number is easier to read than one that publishes a superlative.
A thread on the front, for the next thing
A hood, a cap or a second filter all screw onto it — named explicitly, where two other pages on that shelf never mention a front thread at all. A filter without one ends the stack.
The monopod question
One leg, for the places where three are not allowed. Many venues that refuse tripods admit monopods, and that is most of the reason the shelf exists — the specifications that matter are maximum height, folded length, the lock type and what the foot does on a hard floor.
61 to 176 cm · aluminium · rubber foot · quick clamps · 3-way head for landscape, horizontal and portrait framing · non-slip rubber grip · bubble level · 665 g · 1/4 inch thread, maximum profile 26.7 mm · quick-release plate, bag with a carry strap · no section count published · no declared load published
The only monopod here that arrives with a 3-way head and a bubble level, at 28 € and 665 g — and the only one whose tube diameter is published.
Best for: Someone who wants one purchase that works out of the box, where a head, a plate, a level and a bag matter more than a spike.
Eight euros for a 49 mm colour-neutral UV filter with one coating per side, a 3.4 mm metal frame and a box — and a front thread that still takes a hood or a cap.
Thread size
49 mm, in the title — the smallest on this shelf, where the three others are 67 mm. Forty-nine millimetres is the thread of small primes and older kit lenses, and the buying advice above prefers the largest thread in the bag with step rings below it. This is the filter bought for one small lens
Glass
Optical glass in a black metal frame, in the third bullet, described as colour-neutral. No glass origin is named, where the 11 € K&F and the 13 € PROfezzion both claim Japanese optical glass
Coating description
COUNTED, and precisely: one coating layer on EACH SIDE — a two-fold coating, as the title has it. That is the lowest count on this shelf, against twelve layers on the PROfezzion and eighteen on the K&F, and it is stated plainly rather than dressed up
Frame thickness
3.4 mm, in the fifth bullet, described as a flat mount. Only two pages on this shelf publish a frame figure; the PROfezzion is 3 mm and the two others publish none. Thickness is what decides whether a wide lens sees the ring
Material
A black metal frame around a glass lens, in the third bullet. Black inside the frame is what stops light bouncing between filter and lens, and the colour is worth the mention
Front thread provision
YES, and it is the only page here that spells out what the front thread is for: the fourth bullet says further filters, a lens hood or a lens cap screw straight on. A filter without a front thread ends the stack; this one does not
Stated transmission figure
NOT PUBLISHED. The 13 € PROfezzion is the only filter on this shelf to give one, at 99.5 per cent minimum. With one coating layer per side, the loss here will be larger, and the page does not say by how much

A published 3.4 mm frame and a counted coating — one layer per side
A front thread stated to take another filter, a hood or a cap
One coating layer per side, against twelve and eighteen elsewhere on this shelf
Best for: A small 49 mm prime or an older kit lens that needs a lid over the front element, where a hood or a second filter still has to go on top.
