Photography Fundamentals – How Shutter Speed Changes Your Photos
Last week, I spoke to you about aperture, and how it correlated with the exposure triangle, and how aperture changes your images’ depth of field. That article was just part one of a three-part series that goes over the fundamentals of the exposure triangle, and how each of these settings changes…
Photography Fundamentals – How Aperture Changes Photos
We cover a lot of things over here on the Lensrentals blog, and most of them teeter on the technically advanced edge of the scale. From measuring the flange distance on cameras down to the fraction of a millimeter to performing light tests to check the accuracy of color shift throughout power…
The Great Flange-to-Sensor Distance Article: Part 1 — Cine Cameras
## Part 1: EF and FE Mount Cine Cameras Consider, if you will, the fate of Poor Ben. Unbeknownst to Poor Ben, Aaron and I had started experimenting with measuring the flange-to-sensor distance of various video cameras, since we found that it varied more than, well, more than we had thought it…
Distinguishing the Differences in the Atomos Line of Recorders & Monitors
Atomos is an Australian company well known for its wide variety of monitors and recorders. Not only do you have the ability to record, but change the look of your shot in-monitor in Look Up Tables (or LUTs) to streamline with editing. In some instances you can stream four cameras into one monitor…

Stopping Down Some Bargain Primes and Zooms
In my last post, we looked at how the field curvature of some really excellent 35mm f/1.4 primes affected what happens when we stop down the lens. The takeaway message is that as you stop down, things change a bit differently with the different lenses, but by f/5.6 they were similar. Still slightly…
Some New Wide Angle Lens MTF Tests: Sony 24mm f1.4 GM; Sony 35mm f/1.8; Tamron 35mm f1.4 SP
Most of you MTF junkies are aware that I’ve published all of our prime lens MTF curves in a series of articles by brand, and that I said I would just add new lenses to those articles. I recently tested a series of new prime lenses, though, and thought they were also worth putting up together…
Comparing the Profoto B1X to the Profoto B10 & Profoto B10 Plus
When Profoto released the Profoto B10 back in September of last year, my initial thought was “Oh okay, that means the Profoto B2‘s are discontinued.” Profoto assured myself and others that they were going to continue support for the Profoto B2 still and that we were wrong. When Profoto announced…
A Look at the RED Ranger 8K Production Camera
The most important thing about RED’s new Ranger is that it’s rental only, not because that’s a first for RED (though it is), and not because we’re the only online rental house carrying it (though we are), but because it’s indicative of the customer it’s designed for. This isn’t a camera for…
Just the MTF Charts: Micro 4/3 Lenses
Not a lot to say specifically about the m4/3 lenses except please don’t ask why your favorite isn’t on here; this is all I’ve got. Some of the newer m4/3 have linear electronic focusing which can’t be tested on the bench without a specialized, expensive mount and we don’t have one. Even for the…
Just MTF Charts: Rokinon / Samyang Lenses
I’m going to add some qualifications to the Rokinon / Samyang MTF post. First, the results are a mixture of both brands (which are identical except for the label). Lensrentals stocks mostly Rokinon labeled because of better (the bar is low here) service in the U.S., so the website calls them…
Sony FE 135mm f1.8 GM Early MTF Results
As is sometimes the case, I got access to a couple of pre-release copies of the new Sony FE 135mm f1.8 GM lens. Of course, if I get access, it gets MTF bench tested. I mounted the first one, sipped my coffee and then lost my mind and started shouting various expletives, enough to bring Aaron…
