After a lot of research about tele-converters for my Fuji HS 10 my first choice was going to be the Sony 1.7 lens but it is unavailable apparently, so I decided to invest in the more expensive Raynox. I have only had it a couple of days and am absolutly delighted with the quality of this lens, in my opinion the 2.2 lens quality is unbeatable at the price I paid, there is no difference in the printed 30x zoom or the 66x zoom images. I would recommend this piece of kit to any point and shoot merchant(I include myself)who likes to get some good wildlife shots
