The Sony FE 12-24mm f/2.8 GM (Amazon, B&H) is bigger and heavier compared to the other two lenses. It also has its default manual focus as Linear MF or fly by wire.
The Sony FE 12-24mm f/4 G only opens up to f/4, whereas the other two lenses go up to f/2.8 and gives you an extra stop of light. Sigma Art 12-24mm f/4 DG DN has 11 aperture blades which should, theoretically, give you a smoother bokeh and creamier out of focus backgrounds.
Here’s a resolution comparison:
The Sony FE 12-24mm f/2.8 GM is sharper than the rest at the centre but has a steeper falloff than the Sigma 14-24mm f/2.8 DG DN. I had expected a better performance out of the Sony FE 12-24mm f/4 at f/4.
For those who need f/2.8 and GM quality, there is no doubt which is the better lens. You get what you pay for.
Features
Coverage
The Sony FE 12-24mm f/2.8 GM (Amazon, B&H) is a full frame lens. It is designed to completely cover a sensor the size of 36mm x 24mm.
If you are considering this lens for an APS-C sensor or other cinema camera, check out this article:
Focal Length
The minimum focal length is 12mm. This is considered ultra wide on a full frame 35mm sensor.
The maximum focal length is 24mm. This is considered wide on a full frame 35mm sensor.
This focal range is very useful for long shots and wide shots.
Aperture
The maximum aperture is f/2.8 and the minimum aperture is f/22.
Having f/2.8 is good enough for low light. Most people will use it at f/2.8 for the purpose of getting optimum sharpness, and to get soft out of focus backgrounds.
The Sony FE 12-24mm f/2.8 GM (Amazon, B&H) has 9 circular diaphragm blades. One expects a smooth bokeh, considering the number of blades, but it’s not always a given. To know more about bokeh:
Resolution
From Sony’s official MTF charts:
The Sony FE 12-24mm f/2.8 GM (Amazon, B&H) is as sharp enough in the center and has a steep falloff towards the end at 12mm f/2.8.
While at 24mm f/2.8 the falloff is much farther from the center.
With the variance in the Sagittal and Tangential lines, you can infer (somewhat) that the bokeh won’t be as smooth as the best prime lenses on the planet.
If you really want this lens at its sharpest you’re better off stopping down to f/2.8 or even f/3.5 for best results.
If you are curious and want to read the MTF chart for yourself. Here’s a guide on how to read them easily.
Close Focus
The closest focusing distance is 0.28 meters or 0.92 feet. That’s nice for this focal length because you can use it for close ups as well as wide shots.
Image Stabilization
The Sony FE 12-24mm f/2.8 GM (Amazon, B&H) lens doesn’t have OSS. This is a disappointment, because that would have made it a lot better than the Sigma version. Using it with the Sony Alpha 1 or the a7S III can provide it with some image stabilization.
Is it Parfocal?
The Sony FE 12-24mm f/2.8 GM is not a parfocal lens. To know what a parfocal lens is, check this out:
Control
Manual focus system
The Sony FE 12-24mm f/2.8 GM (Amazon, B&H) has an infinite turn ring for its focus ring and can turn infinitely one way or the other. Fortunately the 12-24mm f/2.8 GM does have Linear Manual focus or fly by wire focus set by default.
What is the meaning of focus by wire and fly by wire?
Focus by wire: Let’s say you turn the focus ring to change focus from point A to B. You’d expect the focus to shift accordingly. When you stop point B will be in focus. Now bring the focus point back to A and try again, but at a different speed. Slower or faster, doesn’t matter. Now, even if you precisely rotate to the exact same degree, the focus will not be on point B! The speed of rotation determines which point it is focused on. That’s just completely useless for follow focus work. If an actor or person moves at a different speed, evens lightly, you’ll never get the same focus. Avoid focus by wire lenses like the plague (for video work).
Fly by wire: The distance of focus shifted is directly proportional to the speed at which the ring is turned. This is how a manual focus ring is supposed to operate for video and cinematography.
This decision to include Linear MF in this lens by Sony makes it a great choice for videographers and cinematographers.
Autofocus system
Sony’s Autofocus is, without a doubt, one of the most revered video autofocus systems in the world. They claim that their new focus system are much better than the previous autofocusing systems. There is a switch on the side of the body to switch from autofocus to manual focus.
A total of four XD Linear Motors, two for each of the lens’s focus groups, contribute to fast, precise auto focus and tracking that augment the many advantages provided by Sony’s native lenses. This advanced system makes full use of the speed potential provided by high-performance camera bodies, making it easier to capture significant moments in the most dynamic sports or other types of action. AF operation is also quiet with minimal vibration.
Sony
Zoom Ring
The zoom ring allows you to manually change the focal length from 12mm to 24mm and anywhere in between.
There is no zoom lock, unfortunately.
Basics
Filter Thread
The Sony FE 12-24mm f/2.8 GM (Amazon, B&H) is not compatible with any filters due to its protruding front lens element. You do get a rear filter holder with a sheet filter template, but that is not the most practical way to using a filter.
Build Quality
The majority of the lens exterior is plastic, though the lens doesn’t feel cheap.
The optical design consists of 17 elements in 14 groups, including three ED (Extra-low Dispersion) glass elements, one super ED glass, two aspherical lenses and two XA (extreme aspherical) lenses.
Size and Weight
The Sony FE 12-24mm f/2.8 GM (Amazon, B&H) has a diameter of 97.6 mm and a length of 137 mm. It weighs around 847 grams. It is pretty light for its class and lens construction.
Weather resistance
Sony claims that all GM lenses are weather resistant. But again this only holds true if the camera body you will be using is also weather sealed. No camera is truly and officially weather sealed, so the best you can hope for is reliable weather resistance.
This is a G Master series lens and we can expect it to perform as such.
What’s in the box
This is what you get in the box (other than the lens):
- Lens front cap: Supplied
- Lens rear cap: ALC-R1EM
- Case: Yes (soft carrying case)
- Filter template
The hood might be useful for photography, but the shape and design makes it mostly vestigial for video work. Some people like to put it on to protect the front element in case of a fall. The hood takes the impact and shatters, but saves the lens. The hood is integrated into the lens to protect the protruding frontal element.
You also get a filter template to cut your sheet filter.
Alternatives to the Sony FE 12-24mm f/2.8 GM Lens
The Sony FE 12-24mm f/2.8 GM (Amazon, B&H) is a great wide angle lens. There only alternatives are:
- Sigma 14-24mm f/2.8 Art (B&H, Amazon) – Same aperture, more blades, cheaper, heavier and bigger, worse AF.
- Cheaper alternative: Sony 12-24mm f/4 G (Amazon, B&H) – Cheaper, Lighter, focus by wire lens with a smaller aperture.
