A85/A75/A70/A60 Wide Conversion Lens Samples

These wide-angle converter samples were taken using the LensMate 37mm and 52mm lens adapters on the Canon A85. You can expect the same performance from the Powershot A60, A70, and A75 as they all share the same lens.  We have included samples at both full wide and full tele zoom positions for each converter to give some idea how well the converter performs as a zoom lens. The images are Large/Superfine jpegs straight from the camera.

We used architecture for the sample shots to show barrel distortion clearly. This is a worst case scenario for wide angle converters. In a natural landscape setting, even the worst barrel distortion may go unnoticed. Additionally, barrel distortion can be removed via software if necessary as shown in the Raynox DCR720 sample.

*The focal length shown in the A85 EXIF is actual, ranging from 5.41mm to 16.2mm.  The 35mm film equivalent would be 35mm - 105mm, therefore the multiplier is about 6.48 when converting one to the other.   Example: 5.41mm (full wide focal length) X 6.48 = 35.05mm (35mm film equivalent).   Note that the focal lengths given below are the actual focal length of the cameras lens.  When you add a wide converter, multiply that focal length by the magnification factor of the converter.  Example:  5.41mm X .72x = 3.9mm.  For the 35mm equivalent, multiply 3.9mm X 6.48 = 25.27mm.

 Though the Tiffen .56x is less than a perfect match for the A85,  (slight vignetting, edge softness) it provides a substantially wider field of view than the other converters tested.  For smaller images, such as those typically used in online real estate, these shortcomings might be acceptable.  If your intention is to print, you might try printing the full size test image at the size you desire and base your decision on that.
