Markins Q20i-RD Knob Shoe Q-Ball i-Type Ball Head

Reliable “rock-solid hold” even with heavy equipment

A professional ball head that lets you lock in composition instantly

The Markins Q20i series is the flagship model optimized for heavy-duty equipment such as large-format cameras and super-telephoto lenses.

In addition to its overwhelming load capacity of 110lb (50 kg), it offers a unique control feel: “it moves exactly as much as you intend, and stops precisely where you want.”
This precise stopping control is why Markins continues to be trusted by professionals in the field.

Do you have any of these concerns?

The equipment suddenly drops when you change composition
Even after tightening firmly, the lens gradually drifts downward
Fine adjustments are difficult with heavy gear

The Q20i solves all of these problems.

Exceptional holding power and smooth operation

As demonstrated in the video, it delivers unshakable holding power even when you take your hands off the equipment.
At the same time, it moves smoothly in proportion to the applied force, allowing you to compose safely and intuitively.

使用約半年、文句なし、色も落ちず、大満足、他社プレートは微妙に合わず、同メーカーが一番。何といつてもレバーの閉め具合、特筆物、お試しあれ、。

GT3542LS＋D800用に購入。購入前に検討したのは、マーキンス、アルカスイス、ＲＲＳの３社。ＲＲＳは、ボールのスムーズ差が他の2社に比べ、イマイチ。Ｚ１とQ20は、正直言ってどちらが優れているのか、わからないほど素晴らしい。国内で買うのであれば、Ｚ１よりQ20のほうが、2万円近く安く買えるが、海外輸入では、同じような価格で買えるので悩みました。Q20に決定した理由は、クイックシュー部分とプレート部分の接合部（シューでプレートを挟んだとき）の隙間が、マーキンス同士だと少なく、接合部分が多い。アルカスイス規格のノブシューならどのメーカーのプレートも使えますが、プレートの厚みが各メーカー微妙に違います。実験したわけではありませんが、ブレにも影響するかもしれません。マーキンスは、GITZOの三脚チューニング等も興味があり、こちらを選択しました。
