Nikon FT1 Adapter: how to use Nikon F-mount lenses on a Nikon 1 camera
The Nikon FT1 adapter enables you to use conventional Nikon F-mount lenses on
a Nikon 1 compact system camera. Here’s how to do it.
Nikon 1 cameras use a different lens mount – and different lenses – to the Nikon D-SLR range, but the FT1 adapter, which sells for around £200, provides the missing link. With this gadget, you can connect any of your Nikon SLR lenses to a Nikon 1 compact system camera.
There are technical differences between these two types of camera. The Nikon 1 uses a much smaller, ‘CX’ format sensor, measuring just 13.2×8.8mm.
This gives the Nikon 1 cameras a crop factor of 2.7x, which means that you must multiply the focal length of any lens by 2.7 to arrive at its ‘effective’ focal length.
The Nikon 1 normally sells with a 10-30mm zoom, which equates to a focal range of 27-81mm, which is very similar to the 18-55mm standard kit lens you get with a Nikon DSLR (27-83mm equivalent).
When you fit one of your DSLR lenses via the FT1 adapter, its focal range effectively becomes much longer. In our walkthrough we use the Nikon 18-55mm DSLR kit lens.
On a Nikon 1 this effectively becomes a 47-149mm lens. It’s a little too long for an everyday lens, then, but it would make a very handy telephoto. Or you could fit a Nikon 70-300mm zoom and effectively get a 189-810mm super-telephoto.
For everyday or wide-angle shots, however, you’d still need dedicated Nikon 1 lenses. Nikon has announced three more lenses to arrive in 2013, one of which will be a wide angle.
The FT1 adapter is designed to allow maximum compatibility between Nikon 1 bodies and F-mount DSLR lenses. The autofocus system can’t currently operate with all focus points, though, so you’re restricted to using the centre AF point only.
In practice, this isn’t a serious limitation, and it’s possible that future firmware updates or cameras may fix this problem.
Step-by-step how to use the Nikon FT1 Adapter
Attach the FT1
The rear of the FT1 attaches to the Nikon 1 body in the same way as a Nikon 1 lens, turning and locking into position. You detach it using the normal release button.
Mount it on a tripod
The FT1 has a tripod mount built into the base. It’s there to redistribute the weight more effectively to reduce stress on the smaller Nikon 1 lens mount.
Fit the lens
Part of the adapter’s job is to position the lens at exactly the right distance from the sensor, reproducing the distance from the lens to the sensor on a Nikon DSLR.
The 18-55mm lens now effectively becomes a 47-149mm telephoto. The autofocus still works, but you’ll only be able to use the centre AF point.
