Raynox HDP-9000EX 1.8x High-Definition Telephoto Conversion Lens

We added this lens to our existing camera we use to video our church services. No light loss with it. Does the job perfectly.

I bought this with the aim of using it with my SONY HX20V P&S camera. I am hoping that the 100mm objective lens will give more light to the small lens of the camera, and at the same time achieve a longer effective focal length. I already have the appropriate step rings and tubes etc to connect the HX20V to the converter and also a tripod collar to mount the converter to a tripod. My main interest is in taking videos of birds and I am glad that the converter is sharp even if I zoom the camera to its maximum focal length which results in an effective FL of more than 1000mm. There is no blurring at the periphery. Chromatic aberration is noticeable only in very high contrast situations like strong backlight. The main problem in this setup is in the focussing system of HX20V in video mode - there is no way to control the focus point and some sometimes, birds are not sharp whereas the background is. I also have the Raynox DCR2025Pro which give 2.2x magnification compared to the 1.8x of this lens. The DCR2025 performs similarly except that it increases the close focussing distance much more than this lens, which I do not like. Before I purchased, I searched Youtube for some example video and was confident that the item suits my need. Overall, I am happy because the lens perform as I expected in terms of letting in more light while maintaining sharpness of the P&S camera.
