Teleconverter for Sony HDRFX1 - Advice needed

[Jonathan Betz]

I am interested in pursuing a career in wildlife cinematography, but I am currently unable to purchase my own equipment. I have access to a Sony HDRFX1, but for filming wildlife, I really need larger than a 12x zoom. Since I don't really have any other choice, I am considering shelling out some money for a teleconverter lens that screws on to the front of the FX1. I know that these converter lenses are not ideal, but I don't have interchangeable lenses and I think I might still benefit from one of these.

 

I am wondering if anyone has had experience using teleconverters, especially on HD cameras. If there are downsides, especially to cheap conversion lenses, what are they and how will I see these disadvantages in my footage? Here are links to the two I have been considering. Obviously there is a big price difference. I can probably only afford the cheaper one myself, but may be able to get some money from elsewhere to purchase something more expensive.
