The Canon G11 has arrived and continues the line of successful Powershot G-Series cameras. We've worked with G-Series since the G2 and they have been some of the best cameras we've ever worked with. Shown below is the evolution of Canon's G cameras.

For the first time, Canon actually pulled back on the camera's resolution, dropping the G11 to 10 megapixels from the G10's 14.7 megapixel resolution. Canon did this to give the camera better low light image quality for recreational shooting. By placing fewer sensors (pixels) on the capture chip, they were able to make each one larger and more sensitive to light. Since we are using a flash for each dental photo, this has little to no bearing on dental image quality.
Canon also brought back the "flip and twist" LCD screen which had been so popular on previous G-Series cameras. The screen shrinks slightly from the G10 (2.8" vs. 3.0") but it is worth it for the flexibility and the ability to protect the LCD when it is not being used. Shown below are the G10 and G11 for comparison.
The PhotoMed G11 Digital Dental Camera is specifically designed to allow you take all of the standard clinical views with "frame and focus" simplicity.The built-in color monitor allows you to precisely frame your subject. Focus and shoot. It's that easy.
Proper exposure and balanced even lighting are assured. By using
the camera's built-in flash, the amount of light necessary for a proper exposure is guaranteed and PhotoMed's custom closeup lighting attachment redirects the light from the camera's flash to create a balanced, even lighting across the field.
Like previous G-Series models, the G11 features two custom settings (C1 & C2) on the mode dial. These custom settings allow you to set a lens position in the zoom range and the camera will set the lens to this position each time you turn the camera to one of the custom setttings.
For dentistry, this allows you to set two specific "magnifications" and repeatedly shoot the same field size over and over. For orthodontics, you can set one custom setting for the 1:2 magnification (anterior, occlusals and buccals) and the other for full face and profile shots.
The G11 Digital Dental Camera System works with all imaging software packages - Windows or Apple operating systems.
Do you already own a Canon G11 camera (or any of the G-Series cameras)? The PhotoMed Closeup Attachment Kit is also available separately to adapt your camera.
