    Used Canon Gear no longer for sale at LensRentals.com?

    It appears that Lensrentals.com is transitioning their used gear for sale to Lensauthority.com. I asked Lensrentals.com about this and received an e-mail saying that they were transferring their used gear slowly to lensauthority.com.

    Sandisk QC lacking?

    I have always relied on Sandisk SD cards. Other brands have let me down in not living up to the rated speeds. I have about a dozen Sandisk SD and CF cards. However, my last two Sandisk SD cards (one an Extreme 32GB and the other an Extreme Pro 32GB) have both been DOA. Neither the camera nor...

    A colleague lent me his new Nikon D800, so I shot video of my resolution chart with it to compare to my (okay, my wife's) 5D Mark III. https://vimeo.com/46242792 My take is that there are some aspects of the D800 video PQ that make it appear sharper, but on closer inspection, its true...

    Sharpening 5D Mk III - red problem and solution

    It is well known that video from the 5D3 benefits from sharpening. However, I was noticing some rather unattractive artifacts when sharpening shots with red in them. The red would pixelate or "ring" at the borders with other colors. The solution I've found (that others might already know about)...
