I did notice when using the Raynox HD-7000PRO on the G7 that one get a small amount of vignetting. It is not at all four corners, on the combo I have it is on the top left and sometimes bottom right. I could remove it in most cases using Photoshop.
As said when I started with this article, this web site does not give ratings to products. The Raynox HD-7000PRO does have a small amount of vignetting at its widest setting. It is also true that this lens goes a bit wider than for example the Canon WA adapter. Therefore with one step forward zoom, then the combo will be very much the same as the Canon standard combo. When you decide to go a little wider setting then be prepared for some Photoshop work.
A few words on the Company Lensmate.
Lensmate was started in 1999 by Susan Doel, making lens adapters for the Kodak DC265 (with a whopping 1.6mp), which was then considered a leading edge consumer camera, but had no means of attaching filters or lenses. A year later the Canon G1 was released. It was truly a class leader with features like an articulated LCD, RAW support, fast F2. lens, and a hot shoe. As the years progressed, Canon's consumer line expanded and so did Lensmate, now making lens adapters in one or more sizes for the Canon A, G, and IS series. At Lensmate, we think PowerShot users can appreciate the effort made to create an adapter that complements the design of the camera as well as enhancing its functionality. Lensmate also tests several wide-angle and telephoto conversion lenses for the same Canon cameras. Test samples can be seen at their web site – www.lensmateonline.com. Some of these lenses are available for sale, along with filters, memory cards, batteries and other accessories.
