*UPDATE* I think we can file these images under the “fake” category without any doubt. Rumors.camera (via PetaPixel) has uncovered where the photos on the LCD screen of the camera came from. It looks like Unsplash strikes again as both images on the rear of the camera come from the site. You can see each Read more…
Professional photographer Dan Carr recently had a chance to borrow a set of ND filters by Aurora Aperture designed for the Canon EF 11-24mm f/4L and other Canon ultra-wide angle lenses. These are rear mount filters.
The set of 4 ND filters from Aurora Aperture includes a 3-stop, 6-stop, 12-stop and 16-stop filters. Dan had a level of excitement for the filters, because it seemed like an easy solution to add ND to the EF 11-24mm f/4L. While it doesn’t solve the circular polarizer challenges, it seemed to easily solve the ND issues in a nice and compact package.
However, Dan found softness issues shooting with the 12-stop and 16-stop filters. You cannot use AF or Liveview focus with ND filters this dark. It’s standard practice to focus your shot and then add the filter and shoot. The 3-stop and 6-stop filters will allow enough light through to focus the show with them equipped.
The 12-stop and 16-stop issue as explained by Dan:
It was immediately noticeable that the shot was soft. So soft that I didn’t need to zoom in on the image to see it. At first I thought that maybe I had nudged the focus ring during the lens removal procedure, but after 4 or 5 more attempts at the same routine, I couldn’t get a sharp shot. For these tests I was shooting the mountains in my local valley, with the focus being set on extremely distant features, basically at infinity.
I also tested the 16-stop filter and had the same problem, so that ruled out a single faulty filter. Read the full story
If anyone else has used these filters and experienced the same problem, please sound off in the forum.
Irvine, California, January 15th, 2018 – Aurora Aperture Inc., a Southern California company specialized in photography filters, today has introduced the world’s first variable graduated neutral density (GND) filter family, the Aurora PowerGXND.
The PowerGXND family is an hard transition GND filter with a continuous range up to 5 stops (ND 0 – 1.5). GND filters are widely used in photography and videography for balancing a high contrast scene for proper exposure.
“The Aurora PowerGXND family is the world’s first variable GND filter,” said Jeff Chen, founder and CEO of Aurora Aperture Inc. “offering a wide range of light balancing capability for both photographers and videographers. Until now users need to carry multiple fixed stop GND filters with light reduction values of one, two, and three stop with no fractional stop value. With our variable GND filters, all you need is one filter and just rotate the filter until you see the desired result, it is truly that easy.”
