G12: Hot Shoe Cover –> No Flash

Hot shoe cover

From time to time there are reports of the G12 internal flash absolutely refusing to work in spite of (almost) every possible corrective action – including resetting – that could be imagined. Frequently the problem is related to a small micro switch located in the hot shoe, see the above image. The purpose of the micro switch is to inform the G12 that an external flash has been attached but if the micro switch has become stuck or unintentionally depressed then the G12 is misinformed. Result: no flash.

The problem is not confined to the G12; the micro switch is used on all the G series Powershots. The photos in this post are of the Powershot G9. The image above shows the G9 hot shoe with a cover designed by Richard Franiec. Notice that Richard cleverly engraved his design with “G” for “Gordon” (although some believe there were other reasons).

Knowing that the G series hot shoe has a micro switch,Hot shoe cover the Franiec cover is relieved along one side so that the micro switch is not activated when the cover is in place. There are other hot shoe covers available but all are not compatible with the Powershot micro switch. The G series internal flash will not work if an incompatible hot shoe cover is placed in the hot shoe.

I bought my G9 hot shoe cover directly from Richard and the G12 hot shoe cover from Lensmate. The same cover is used for G7 through G12.  My G3 and G6 also have the micro switch but the Franiec cover is just a bit too wide to fit.

There have also been reports of a stuck micro switch but more often the “flash doesn’t work” problem seems to be an incompatible hot shoe cover.

Dressing up the G9

I've installed four G9 accessories designed and crafted by Richard Franiec: Ring, Grip, Thumb Rest and Hotshoe Cover. The Ring is purely esthetic – a simple black metal ring to replace the original black and silver one. The Grip and Thumb Rest really do improve handling. The Hotshoe Cover is for protection and to prevent snagging. These are all simple ideas that have been very well accomplished by Richard. They fit the G9 so well that you probably don’t notice the difference in this picture. Take a closer look. You can actually see all four accessories in this photo (but the thumb rest is just barely visible on the back of the G9). Click on the image for a larger view.

The wrist strap is obviously not from Richard. For a small camera like the G9, I prefer a wrist strap to a neck strap. This one is for a Canon camcorder. I used a similar one for years with my Canon G3. However, I did not pay close attention to the mounting bar on the G9 – it is smaller than the mount on the G3. Therefore I had to add a small metal ring to the G9 mounting bar. I do like that particular wrist strap but don’t make the same mistake I did if the metal ring bothers you (I don’t like the ring).

Richard’s products were first conceived for the Canon G7. In particular, the G7 Grip has been very popular. Although the G9 is naturally somewhat more ergonomically friendly, Richard’s G9 Grip (not the same as the G7 Grip) is an improvement. I’m glad I bought it; in fact, I’m glad I bought all four accessories.

The Grip and Thumb Rest are easily installed by following Richard’s detailed instructions. Double sided adhesive tape holds the Grip and Thumb Rest in place -- just peel off the backing and press. Be sure to wipe the camera surfaces with alcohol to remove any skin oil. Also, be sure to practice installing before removing the backing!
The Ring is a simple replacement: remove the Canon ring and install Richard’s Ring. You’ll have to look closely at Richard’s Ring to get the correct orientation but this is explained in his instructions. The Canon ring has a tiny white dot that matches a tiny black depression on the body. Richard’s Ring is all black; it is oriented correctly when the shortest mounting tab is at the top. Both the Canon ring and Richard’s Ring must be removed to install the auxiliary lens adapter. Sad to admit, but both of my rings now have a white smear on the shortest tab (not visible once the ring is installed).

The Hotshoe Cover is Richard’s latest product. It simply slides into place on the hotshoe. The large engraced letter “G” (for “Gordon”, I assume!) is a very nice touch and indicative of Richard's attention to detail in all his products.
