On January 6, 2016 Olympus announced officially their new High-performance, super-telephoto lens, and it sure looks like a winner from the specifications.  I can’t wait to get my hands on this baby for a test!  For now, here’s their full press release. M.ZUIKO DIGITAL ED 300mm f4.0 IS PRO (35mm equivalent focal length: 600mm) The […]

Built in Germany by Schneider-Kreuznach, the new […]

Everyone by now has heard the sage old advice told to every young photographer without a zoom lens.  Use your feet.  Or Sneaker Zoom, as most of us old timers call it.  Sneaker Zoom means getting closer or farther away from your subject to effectively change your angle of view without having to change the lens itself. […]

When Lensrentals.com first got the first Canon 5Ds and 5D sr cameras in stock, Aaron and I immediately started screaming that we wanted to take one apart. It turns out we received enough 5Ds cameras to let us have a day with one to do just that. Of course, we don’t expect to find out anything amazing and revealing. We expect […]

Editors Note: With the rumor mill alive with speculation about a soon to be announced Sony A7R Mark II with a whopping 59MP of resolution, a discussion immediately came up with some of my professional photographer friends about where is the actual diffraction limit going to be with a Sony 59MP full frame sensor?  The limit being the […]

Rollei lenses on a Sony A7S?  Is this possible?  Yep, Rollei lenses on a Sony A7S, and the results may  surprise you as much as they did me.  Not only is the video superb, the still images are every bit as magical as their medium format counterparts.  Rollei lenses on a Sony A7S for me? You better […]

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 […]

Perspective correction, or “tilt–shift” as it is often called, encompasses two different types of movements: rotation of the lens plane relative to the image plane, called tilt, and movement of the lens parallel to the image plane, called shift. Tilt is used to control the orientation of the plane of focus (PoF), and hence the part of an image that […]

For regular all around shooting, I find the Contax Zeiss 85mm f1.4 Planar to be a bit too long for my video tastes. I have not spent nearly the time shooting this tight of a lens as I have with wider angle lenses.  On my other hybrid storyteller hand, for still portrait work the Contax Zeiss 85mm f1.4 Planar […]

Matt Granger, from ThatNikonGuy.Com digs into the difference between F Stops and T Stops in this short presentation.  Just what is that difference, and is that difference important to us, you mite ask? In the science of optics, the f-number (sometimes called focal ratio, f-ratio, f-stop, or relative aperture) of an optical system is the ratio of the lens’s focal length to the diameter of the entrance pupil at the […]

Here are some additional field test images from the Zeiss Touit 32mm f/1.8. We used the lens (loaner from Zeiss) with our X-T1. Some initial thoughts: Very good sharpness as we expected A focal length of 32mm (48mm at 35mm equivalent) proves to be good for general street photography (at least for us). AF not […]

The Optikos Bench First and foremost, if you aren’t at least a little Geeky, this post is not for you; unless you’re one of those people who thinks “just take some pictures, dammit,” when I write some article about resolution testing.  In that case, you might like this article because we’re taking pictures to test […]

What is Decentering and What Does it Do? Strictly speaking, decentering would involve one or more of the lens elements being off of the central axis of the lens. This would prevent the curved surfaces of the lens from bending the light properly. In severe cases it could result in halos or ghosting. In most […]
