Lensmate announces the arrival of the new
Powershot S100/S95/S90 Quick-Change Filter Holder.
Now you can add filters to your S100/S95/S90 without a bulky tripod mounted adapter.
Only the tiny receiver stays on the camera (it adds only 3mm to the depth of the camera). The filter/filter holder assembly bayonets onto the receiver for quick changes without having to thread the filter on and off. The filter holder is retained by a low tension locking system, so very little torque is applied to the lens barrel when attaching and detaching it.
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 2mm (about 1/8") to the total depth of the S100 camera and 3mm for the S95/S90. 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 filter users.
The S100/S95/S90 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.
- 37mm clip in style lens cap.
- A hinged lid container for the filter/filter holder/lens cap assembly for convenient storage.
- Safe removal device.

S100/S95/S90 Quick-change filter holder attachment directions
Use the alcohol wipe to clean the front of the lens barrel. Use just a corner of the wipe - use care not to squeeze excess fluid onto the camera.
Turn the camera on. Don't zoom the lens, just remove the battery.
Slide the cardboard tube over the lens until comes to a stop against the next section of the lens barrel.
Separate the receiver from the filter holder.
Carefully peel away the clear backing on receiver, rotate it to the desire orientation, and lower one edge into the tube keeping it angled as shown. Don't press it down just yet.
Now you can still adjust the receiver until it's rotated to your liking. Once you press it down, there's no more adjusting possible (without removing it).
When you're happy with its orientation, press the receiver down gently and remove the guide tube (keep it in the resealable bag for the next use). Replace the battery, and turn the camera off. When the lens is in the closed position, press firmly on the receiver and you're done.
Removing the Lensmate S90 Quick-change receiver from the camera
Don't turn the camera on, just remove the battery. Lay the camera on its back. Let the thread of the removal tool find the space between the receiver and the end of the lens. Loop it all the way around and pull the two rings apart slowly - it should easily separate the two.
Don't reuse the same adhesive once removed as it's probably been compromised in the removal process.
Attaching a replacement adhesive sticker.
To replace an adhesive sticker, first remove any residue from the back of the receiver. Acetone or nail polish remover works best. Find the slit in the kraft paper backing of the adhesive sticker and peel away the paper. While keeping the adhesive sticker centered over the receiver, press it down firmly. Now it's ready to reapply to the camera. Using the installation tube guide as before, remove the clear backing from the adhesive sticker and apply the receiver to the camera.
1. We recommend attaching and detaching filters from the filter holder when it's off the camera. In fact, you can't unscrew the filter from the filter holder on the camera because it will just remove the filter/ holder assembly as it was designed to do. Don't over tighten the filter - it requires little force to stay attached to the holder.
2. If you use a snug fitting bag or case, we recommend removing the filter holder/filter assembly before stowing the camera. If you do leave it on, be sure to check that the filter holder is still in the locked position when you use it again.
3. Some polarizers rotate with enough friction to remove the filter holder assembly when rotated in the direction of removal. If this happens, rotate the polarizer in the direction of attachment only.
4. If you use a wrist strap, be aware that jostling can dislodge the filter holder from the camera.
Macro Samples
This test was done using the Lensmate S95/S90 Quick-Change system with the Canon S95. Because the S95 built-in lens is slightly larger in diameter and longer in length, we will have macro samples for the S100 in the near future.
The purpose of this test is to compare the built in macro mode of the Canon S95/S90 with some of the more common macro lenses/filters available. Included are the Canon 250D, the Hoya +7 Macro set (+1, +2, +4, and combined +7), the Raynox DCR-250, the Hoya +10, and the Raynox MSN 202 and 505. We then evaluate each set of samples looking for softness and/or CA, particularly in the corners.
The focal range for the S95/S90 is 6.mm to 22.5mm, or in 35mm terms, 28mm - 105mm. Focal lengths given in the EXIF information are actual. To convert to 35mm film equivalent, multiply by 4.66. Basic camera settings are ISO100, Large JPEG, Custom white balance and the IS turned off (because the camera was mounted) and self-timed shutter release. 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 10.7mm (about 50mm equivalent) and full telephoto – 22.5mm (105mm equivalent). The first setting is halfway into the macro range, or 5 zoom steps. This allows adequate working distance for light to reach the subject. The second sample is taken at full telephoto. Width of the frame is at the minimum working distance for each sample.
