Sony FE 90mm f/2.8 G OSS Resolution Test
We got a pre-release set of Sony FE 90mm f/2.8 G OSS Macro lenses in for preliminary testing last week, and I was kind of excited about this lens for a couple of reasons. First it simply gives me a nice short telephoto prime option that has been lacking in the lineup (although the Zeiss 85mm Batis…
Canon T6 Sensor Issue
NOTE: As of May 8th, Canon has issued a recall of affected units. My hat is off to them for superb Customer Care. I didn’t dream it could be done this quickly. Roger Every once in a while we notice something, because of the large quantities of cameras and lenses we buy, that we think people should…
The Best Products of NAB 2015
This past week, I had the unique opportunity to go to the National Association of Broadcasters’ trade show, more commonly known as NAB. To say NAB is massive, is a gross understatement; with over 100 thousand people in attendance, and over 1 million square feet in booths and other showrooms, NAB is…
Infrared Photography: Imaging in a Different Light
### Creative Experimentation As a photographer with an art background and an employee of a company with endless gear options, I am always looking for something to give me a fresh perspective on image making. On our recent trip to the Wedding and Portrait Photographers International Conference+Expo…
Tearing Down the Sony 24-70 f/4 ZA OSS Vario Tessar
Those of you who read our teardowns know that we commonly are tearing down Canon or Nikon mount lenses. The reasons are pretty simple and it basically comes down to the fact that we have a lot more of those lenses. If we have a lot more it’s less of a problem to take a couple out of stock for a…
Sony FE 35 Match-up: Is More, More?
### Time to trash the adapters? Sony has just released a new line of full frame FE lenses that will hopefully eliminate the need to use adapters with lenses from other systems. We just received the Sony FE 35mm F/1.4 ZA Distagon which has the largest aperture in the lineup and we couldn’t wait to…
Just the Lenses: Sigma 24 f/1.4 Art Comparison
Most of you know I’ve been very impressed with Sigma’s new Art lenses. Their 35mm f/1.4 Art I still think is the sharpest 35mm prime lens made. The 50mm f/1.4 Art is also superb. When I heard about the Sigma 24mm f/1.4 Art lens, I had some mixed emotions. I was excited that we might get a 24mm lens…
Announcing C-4 Precision Optics
## Or, What I Did Over Winter Slow Season Those of you who read my blog regularly know I’m not a huge fan of sameness. But new lens releases, lately, have tended to have a lot of sameness. Don’t get me wrong, there have been some excellent lenses released; marked improvements and refinements have…
Just the Lenses: The Great 200mm Shoot Out
For those of you who haven’t read our ‘Just the Lenses’ posts before, these take advantage of our Trioptics Imagemaster optical bench to compare lenses from different camera mounts with no camera involved. Why is that different? Because all other forms of testing (DxO, Imatest, or even photography)…

A Quick Zoom Variation Demonstration
Sometimes I put up posts basically because I find myself answering the same email over-and-over. One of the emails I get a lot is: “I want the best copy of the xxxx zoom lens.” People get irritated because my response is usually something like this: Which focal length do you want the best copy at?…
SLR Magic’s 50mm APO HyperPrime Cine T2.1 MTF Tests
* Zeiss 50mm CP.2 and SLRMagic 50mm T2.1 * About a year ago, Andrew from SLR Magic came and spent a couple of days in our lab, testing some of the SLR Magic lenses and getting input on improving the optical adjustments on their lenses. At the time Andrew made it clear their company wanted to up…
