Canon PowerShot A3100 IS Review

May 13, 2010 By Eric Reagan

The Canon PowerShot A3100 IS is an entry-level digital camera that keeps shooting functions basic, yet delivers great quality images for a camera of its size and price range.  There are no shiny bells and whistles to go along with the camera, but it makes good on its fit into the category of “point and shoot.”

To see whether the Canon A3100 IS delivers enough for your needs, read on. [Read more…]

Tamron Announces 70-300mm F4-5.6 Di VC USD Lens

March 9, 2010 By Eric Reagan

Tamron 70-300mm F4-5.6 Di VC USD

Tamron has announced the development of a new 70-300mm F4-5.6 Di VC USD for Nikon, Canon and Sony mounts. The new lens is the first from Tamron to incorporate Ultrasonic Silent Drive AF motor for faster autofocus.  Additionally, the lens will include Tamron’s Vibration Compensation (except for Sony mount) to reduce shake-induced blur in images.

Tamron will release the Nikon mount version first, and then follow on with Canon and Sony versions.  Tamron has not announced a price for the lens at this time; however, it matches up squarely against the Nikon AF-S 70-300mm f/4-5.6 VR and the Canon EF 70-300mm f/4-5.6 IS USM, both of which are in the $500 range.

More details in the press release below. [Read more…]

Canon Patent Application Shows Sensor-Based Image Stabilization

January 25, 2010 By Eric Reagan

Canon Sensor Stabilization

In addition to the dual image viewfinder system in the recently-published Canon patent applications, the Canon applications also reveal a mechanism for sensor-based image stabilization in a DSLR.  Again, the application numbers are 12/495,813 and 12/495,814, and were each filed on July 1, 2009 and published by the USPTO on January 7, 2010.

The relevant description in the patent notes the following:

“The camera performs an image capturing operation.  In this state, an image stabilization mechanism, which is connected to the stabilization control circuit, can shift and rotate the image sensor in a predetermined direction to cancel the blur of an image.  Thus, the image stabilization mechanism can prevent the image from shifting undesirably and lowering the resolution.” – USPTO App. No. 12/495,813 at ¶ [0049]

Again, these patent applications specifically deal with the functionality of a dual image viewfinder system.  This portion of the patent claims was mentioned almost in passing and does not appear to be a material part of these patent applications.

Given Canon’s past marketing claims concerning the superiority of lens-based stabilization systems, however, I found this mention in Canon’s patent worth noting separately.

As I have said before though, this does not necessarily mean that Canon is producing a camera with a sensor-based stabilization system.

4 Principles of Photography Marksmanship

December 7, 2009 By Eric Reagan

Marksmen use a handful of fundamental principles to take aim, fire and hit their target.  Many of these same principles can also be applied by other kinds of shooters – photographers.

When marksmen fail to abide by those principles, they may miss the bulls-eye.  When photographers fail to follow them, they may end up with a blurry photo. [Read more…]
