Lensmate announces the arrival of the new
Powershot G12/G11/G10 Quick-Change Filter Holder.
If you've ever wanted to add just a filter to your G10/11/12 but didn't want to deal with tube adapters, Lensmate has the answer for you.
Our new Quick-Change Filter Adapter allows you to add or remove a filter with just a quarter turn of the filter. Only the low profile receiver stays on the camera, barely noticeable when not in use and adding only about 3mm or 1/8" to the depth of the camera.
Note that this system is intended for filter use only, or the Raynox DCR250 macro lens, you still need to use our standard G10/11/12 tube style adapters for mounting conversion lenses, macro ring flashes, or square filter holders.
There is no chance of flash blockage at any focal length (with the filter holder removed), since the receiver is the same diameter as the end of the lens barrel. The receiver adds only 3mm (about 1/8") to the total depth of the G12/G11/G10 camera. It attaches to the camera using a 3M dual-sided adhesive film which holds tenaciously yet is easy to remove cleanly and safely when desired.
We designed the system so that the filter remains in the filter holder and is attached/detached as an assembly. The filter holder bayonets onto camera with less than 90° of rotation to the locked position.
The low tension locking system assures that the lens barrel won't be harmed by over-enthusiastic tightening (or loosening) of the filter. The ability to quick-change the filter in changing light conditions without having to thread/unthread should appeal to all filter users.
The G12/G11/G10 Quick-Change Filter Holder kit is comprised of the following:
- The receiver with adhesive ring (Part 1 - stays on the camera)
- The filter holder (Part 2)
- Installation guide tube.
- 52mm clip in style lens cap.
- A hinged lid container for the filter/filter holder/lens cap assembly for convenient storage.
- Safe removal device.

Macro Samples
This test was done using the Lensmate Quick-Change system. Compared to the Lensmate tube adapter setup, results were similar. The most noticeable difference was seen with the smaller diopters like the MSN 202 and 505 - the Quick-Change system shows no vignetting at maximum focal length and has a slight edge in image quality. There were also differences in working distances with some diopters.
The purpose of this test is to compare the built in macro mode of the Canon G12/G11/G10 with some of the more common macro lenses/filters available. Included are the Canon 250D, the Hoya +7 Macro set (+1, +2, +4, and +7), the Raynox DCR-250, the Hoya +10, and the Raynox MSN 202 and 505.
The focal range for the G12/G11/G10 is 6.1mm to 30.5mm, or in 35mm terms, 28mm - 140mm. Focal lengths given in the EXIF information are actual. To convert to 35mm film equivalent, multiply by 4.59. Basic camera settings are ISO100, Large/Fine JPEG, Custom white balance and the IS turned off (because the camera was mounted). We used an aperture of f6.3 to maximize depth of field, which can be paper thin with the more powerful diopters like the MSN-202.
"Distance to subject", or "working distance" means distance between the actual macro lens and subject. In this test, we give working distance range, which is the range between nearest possible working distance and most distant.
You can view a full size quarter crop (bottom left corner) which shows the corner, edges, and center of the image.
Except for the first sample showing the built in macro mode at full wide, each macro lens is shown at 14mm (about 64mm) and full telephoto – 30.5mm (140mm). The first setting is halfway into the macro range, or 5 zoom steps. This allows adequate working distance for light to reach the subject, and is also almost distortion free compared to the full wide setting. Though the full telephoto setting (12 zoom steps) is supposedly out of the macro range (0 – 10 zoom steps), it provides a little more magnification and working distance. Width of the frame is at the minimum working distance for each sample.
You might notice that all samples exhibit some degree of corner softness at full telephoto when viewed at 100%. This can be attributed to the native lens which shows slight softness as can be seen in the native macro samples.
I wanted to let you know that I added the LensMate Filter Holding Kit to my new Canon G12 last month, used with the Hoya UV 52mm filter and the lens cap, all purchased from you prior to my recent 17 day trip to Argentina and Antarctica. You were wondering whether the 3M adhesive would hold up under varying temperature extremes, so I bought an extra adhesive ring.
The 3M adhesive never came off, the Quick Change parts one and two stayed on through numerous lens cap on-and-offs in 90-100 degree humid weather in Buenos Aires and the jungle at Iguazu Falls, and in freezing 26-32 degree weather in Antarctica, out in the boats and hiking daily on the land mass during a 10 day cruise! The camera was also in and out of the warm expedition ship frequently during each cruise day with constant outside/inside temperature variation! So your products and the adhesive held up very well in these extremes of temperatures! My friend, Mr. Marc Gershwin, bough the Canon 58mm filter adaptor which he had to remove because it blocked the furthest extension of the lens when zooming out and caused vignetting. He will be ordering from you soon.
Thanks again, Peter from Fort Wayne IN
