You'll need an adapter with a correction lens in it for infinity focus.
No correction lens and you'll only have an extension - so it would work for macro.

Adapters with correction lens and focus confirm start at about £40 to £45 - Pentax K to Nikon AF

I don't know if it is worth it in this case.

Correct adapter with infinity focus correction element, would let you mount non AF, non Nikon F-Mount lenses., BUT; without the electronics in the lens to talk to the camera, the D3200 will have almost all of its functionality disabled. Asides from having to manually focus, you will also not be able to use the camera in anything but full manual mode, WHERE to make matters a tad more awkward, it will also NOT provide any 'hi-lo' metering indication; you will have NO in camera metering; you will have to get meter readings from the camera using an AF lens on it, or use a hand held meter, or meter by eye, or Chimp.

As to the SFX & lenses? More research required. It was an early AF SLR and I don't know & cant discover enough to say whether the SFX was designed to allow earlier Pentax K mount lenses to be mounted I have a suspicion is may be one of those anomalous ones, with short lived mount of ts own, in which you might struggle to get an adapter, and THEN struggle with what functionality you get out of the lens, without it able to talk to the camera it was designed for.

It's not a particularly fast lens, and the zoom range isn't far off what you got with Nikon 18-55 kit, so my gut reaction is that its probably not worth the hassle all told; leave it on the camera its native to and save your money for FILM!!!!

^^^ This. Waste of time basically. Pentax SFX was Pentax K bayonet mount. Converting old lenses is a highly over-rated pastime IMHO. It's a shame, but there's a reason why old kit like this often ends up at car-boots.

The sfx and the f series were Pentaxes second attempt at AF. The 35-70 is a very good lens but the macro is only a 1:4 so OP won't have the full benefit of macro.

All k/m/a/f/fa fit lenses fit on the newest Pentax cameras, rk (Ricoh) is not recommended on AF bodies, others have limited functionality but a lens made in 1975 will fit and work on a K1.


For a D3@00 what is an inexpensive F-mount option?
