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.

Canon DSLR Dual Viewfinder

A pair of recently published Canon patents reveal a new viewfinder system for Canon DSLRs that will allow photographers to “chimp” their shots without ever taking their eye off the viewfinder.  The patent applications filed in the United States Patent and Trademark Office (“USPTO”) under application numbers 12/495,813 and 12/495,814 were each filed on July 1, 2009 and published by the USPTO on January 7, 2010.

The essence of the technology claimed under the patents is an advanced viewfinder system that uses a small backlit LCD or OLED inside of the finder to project previously captured images onto a mirror in the pentaprism, which in turn, is reflected toward the eye of the photographer.  As a result, the photographer sees two images in the viewfinder – the live optical image and the previously-captured image from the LCD.

The purpose of this invention, as stated in the patent, is to help the photographer be more efficient by keeping his or her eye in the viewfinder and not having to pull away from the action in order to check exposure, white balance, focus and so on. [click to continue…]

Impact EX100A Monolight

The Impact EX100A is a basic 100 watt monolight that’s available from B&H Photo.  The EX100A is also available in a 2 monolight kit with 24″ softboxes, an umbrella, light stands and a carry case.

The EX100A 2-light kit was my first experience with using monolights, and for the $200 I spent on it, I have been pretty pleased.  Sure, it’s not AlienBees, Elinchrom or anything fancy, but not everyone needs (or can afford) those brands. [click to continue…]

CNA, a large commercial insurance writer, has introduced a line of insurance products that are specifically tailored to photographers and videographers, including errors and omissions coverage related to client dissatisfaction, events that can damage reputations and legal expenses.

Details on the coverages are slim at the moment on CNA’s website, and look to be custom designed coverage based on the individual photographer’s needs.  You can get an overview of the new line of products offered by CNA in their press release below.  If it’s something that interests you, your best bet would be picking up the phone and talking over the details with a CNA agent.
