I don't know what the real focal length is, but it is similar to other 200mm lenses. Probably in the mid 190's. Other 200mm lenses will not give you more reach, basically... so for all intends and purposes, it is 200mm.
I know that most suggest the Pro 300, because it is more expensive. But the cheaper one does perform similar. It is not like the ones who say the Pro 300 is the one to go for actually compared it with the cheaper one...
Both will do fine, basically.
Like I mentioned before, the Soligor 1.7x TC is a nice inbetween option. If you still find one, you might want to get it (very affordable), to complement the 1.4x when extra reach is wanted.
The aperture of the whole optical system goes down one stop with the 1.4x TCs (so, f2.8 -> f4), 2 stops with 2x TCs (2.8 -> 5.6) and 1.5 stops with the 1.7x TC.

Thanks again! I will look if I can find a Soligor 1.7x TC to buy.
Best regards,
