PLAUBEL makina 67 Genuine Diopter Correction Ring +1.0 This is a genuine accessory, a diopter correction lens with +1.0 diopter. It is used by replacing the standard eyepiece ring. +1.0 is a correction for farsightedness (or a plus correction for those with presbyopia), and it has the effect of making the viewfinder image clear and easy to see. Genuine products are very rare, and I think the plus-side correction rings are especially scarce. --------------------------------------------------------------------------------- - Everything in the photos is included. - Please refrain from comments or requests for price reductions if you are not serious about buying. - I will conduct transactions with the person who completes the purchase procedure first, even if negotiations are in progress or have concluded. - The item will be shipped via Nekopos. - I will use recycled packaging materials.
