A number of places that spec could be, in the prism of the camera is one lens is another sensor another and view finder the next.
to find out if the spec is on the sensor take white paper and take a shot into the white paper and then if spec is on the paper the sensor will need cleaning.
cleaning the sensor is a delicate prosedure and I personally am not patient enough or delicate enough to undertake the task so i go to my local photography shop and get it cleaned with an hour service , I normally time this around lunch time and go have some lunch in the town, by the time i am finished with lunch it is generally ready.
this service cost me £40.00 and they do a good job.

It won't be in the lens. Any marks on the lens will be too out of focus to appear in the pictures or the viewfinder.

Sounds like it's the viewfinder. Just to be sure it's not on the sensor, take a shot of the white paper, as suggested, but set a small f-stop.

Thank you everyone I have done a white paper shot and cannot see the speck on the image - I will do a blue sky small aperture shot tomorrow (if the clouds have gone) I did swap lenses and it still shows up in viewfinder so I suppose that means viewfinder or mirror. I'll let you know how it goes Cheers
