Amazon Basics 67 mm, no coating or thickness published
Nine euros for a 67 mm protective lid whose five bullets describe what it is for four times over, and its construction not once.
- Thread size
- 67 mm, in the title and the fourth bullet, which calls it compatible with a wide range of lenses. Sixty-seven millimetres is the thread of a great many standard zooms, and it is the size the buying advice above says to buy for and step down from
- Glass
- NOT SPECIFIED. No origin, no type, no grade — where the 11 € K&F and the 13 € PROfezzion on this shelf both name Japanese optical glass and the 8 € Hama names optical glass in a black metal frame
- Coating description
- NONE, and this is the specification whose absence costs most. An uncoated filter reflects light between its surfaces and the lens, which lowers contrast and can throw a ghost of a bright source into the frame. The hub above is blunt about it: an uncoated filter in front of a good lens is a downgrade you pay for. The other three filters here publish 2, 12 and 18 layers
- Frame thickness
- Not published. The 8 € Hama gives 3.4 mm and the 13 € PROfezzion 3 mm; on a 67 mm filter destined for a standard zoom, thickness is what decides whether the corners darken at the wide end
- Material
- Not named. Neither the frame metal nor the glass is described anywhere in five bullets
- Front thread provision
- Not mentioned. Whether a hood, a cap or a second filter screws onto the front is left unstated — the 8 € Hama names all three
- Stated transmission figure
- Not published
- Amazon reference
- B00XNMX4EG (same reference on 6 Amazon marketplaces)
- EAN
- 0848719099393
- Sixty-seven millimetres, the thread the buying advice above says to standardise on
- Nine euros, the cheapest 67 mm lid on this shelf
- No coating described at all, on glass that sits in front of every photograph
Best for: A lens that lives in a bag with sand and keys, where a 9 € replaceable lid is the point and image quality is carried by the hood instead.
