  • Canon patent shows curved sensor design

    A new patent suggests Canon’s engineers might be working on a curved sensor design to reduce vignetting. Japanese blog Egami reports on a patent that was released on the 24th of November and describes an image sensor design with a flat central portion, where light fall-off from the lens is not much of an issue, and curved edges, where fall-off is generally more noticeable. This approach, rather than using a sensor that's totally curved, would avoid making the whole unit much thicker.

    Such a sensor design could potentially be applied in mirrorless camera models where, due to short flange-back distances, vignetting is generally more of a problem than on conventional DSLRs. Software processing can correct for the effect but only to a certain degree, so it would not be a surprise that manufacturers are looking for hardware solutions.

    As with all patents, it's impossible to know if the technology will ever make it into a production model but it's good to know manufacturers are looking at innovative ways of improving image quality.

  • Think Tank Photo Outlet Center launches with discounted goods

    Think Tank Photo has launched a new online Outlet Center offering discounted camera bags. These items, as is sometimes the case with outlet stores, are new products that may for one reason or another lack their original packing material and/or their sales tags. The Outlet Center currently lists 16 bags, though no doubt the number will fluctuate based on inventory. Price reductions are steep, and include the Shape Shifter bag, originally priced at $264.75, for $149.75.
