The Nikon Z 400mm is dangerous for people with pacemakers

The Nikon Z 400mm f/2.8 TC VR S was introduced recently. This lens uses a Silky Swift Voice Coil Motor. People with a pacemaker should not use this lens.

That warning comes from Nikon itself, and can be found in the lens manual.

“Do not use this product if you have a pacemaker or other medical device. The magnet or magnets in this product could cause medical devices to malfunction.”

The Silky Swift Coil Motor is an interesting name for a focusing system that uses strong magnets. As most people probably know, magnets can interfere with the operation of a pacemaker. That is why people with such medical devices are advised not to use this lens.

Whether the magnets in this lens will actually interfere with a pacemaker is of course the question. But Nikon is playing it safe and has therefore included this warning in the manual. American claims culture will certainly play a role in this as well.

Considering the price of this lens, almost 15,000 euros, there will not be many people who end up owning the Nikkor Z 400mm f/2.8 TC VR S. But I would not be surprised if this magnetic focusing system eventually appears in more lenses.

If you have a pacemaker and enough money to buy this Z 400mm, it would be wise to look at an alternative. After all, you do not want to risk something going wrong.
