The Canon SX40 HS is a compact bridge camera with an extreme zoom lens. It offers focal length settings between 24mm and 840mm (35mm film camera equivalent), which allows users to shoot nice wide-angle shots to extreme telephoto images. Adjusting the zoom lens between 24mm and 300mm is easy and allows a nearly continuous setup of the desired field of view. However, zooming between 500mm and 840mm requires more work.

The Canon Rebel T6s and T6i are based on the same camera design: Both use an APS-C sized sensor (Canon's “APS-C” with 22.9 x 14.9 mm) with a resolution of 24MP. They also use the same image processor, the DIGIC 6. However, there are some design differences. While the TS6i looks like a little modified version of its forerunner T5i, the design of the T6s is more reminiscent of the mid-range SLR system EOS 70D. The illustrations provided show the differences in design and setup between the two models.

The DxO One is a pocket-sized camera module for the Apple iPhone or iPad that offers a one-inch sensor with 20MP resolution and a fixed focal length of 32mm (35mm film equivalent). The camera uses the iPhone and an app as both the control center and electronic viewfinder.

The HS30EXR has a surprisingly heavy and massive body and is nearly the size of an entry-level SLR system combined with a superzoom lens. The grip on the right-hand side fits perfectly into the photographer’s hand, while the left hand supports the lens system and is used to change focus and focal length manually with two large lens rings. The focal length ring has a nice rubber coating and is easy to handle, while the focus ring is very thin and is located near the body of the camera, which makes it a bit less easy to handle. Focal length adjustment is done via a mechanical regulation of the lens system, while the focusing ring adjusts via a servo system.
