What does DC HSM mean?
According to Sigma, DC refers to the lenses that are designed specifically for APS-C DSLR cameras. Sigma claims that their DC DN lenses are designed specifically and exclusively for APS-C mirrorless cameras.
So while the DC HSM will work with a APS-C mirrorless photographic camera, with an adapter, a DC DN lens will communicate naturally with the camera than the DC HSM lens.
HSM refers to their band-type hypersonic autofocus motor in that lens.
Features
Coverage
The Sigma 30mm f/ane.4 DC HSM Art (Amazon, B&H) is an APS-C sensor lens. It is designed to completely cover a sensor the size of 25.1mm x xvi.7mm.
If you are considering this lens for a full frame sensor or other picture palace photographic camera, bank check out this article:
Focal Length
The focal length is 30mm for an APS-C sensor. The focal length will be 48mm on a full frame 35mm sensor. This is considered normal wide on a full frame 35mm sensor.
This focal range is very useful for wide angle shots, drone work. Being between 35mm and 24mm, this is a focal range perfect for long shots.
Discontinuity
The maximum aperture is f/1.four and the minimum aperture is f/16.
Having f/i.4 is smashing for low light. Most people will use it at f/two or f/2.8 for the purpose of getting optimum sharpness, and to get soft out of focus backgrounds.
The Sigma 30mm f/1.4 DC HSM Fine art (Amazon, B&H) has 9 diaphragm blades. One expects a polish bokeh, considering the number of blades, simply it's not always a given. To know more than about bokeh:
Resolution
From Sigma's official MTF charts:
The Sigma 30mm f/1.iv DC HSM Art (Amazon, B&H) is sharp in the center and has a gradual fall off towards the edges.
With the variance in the Sagittal and Tangential lines, you can infer (somewhat) that the bokeh should exist smooth enough.
If you actually want this lens at its sharpest you lot're ameliorate off stopping downward to f/2 or even f/ii.eight for best results.
If you lot are curious and desire to read the MTF chart for yourself. Hither'southward a guide on how to read them hands.
Close Focus
The closest focusing altitude of this lens is 30cm or 0.98 feet. That's great for this focal length because you tin too use it for close ups.
Image Stabilization
The Sigma 30mm f/1.four DC HSM Fine art (Amazon, B&H) lens doesn't have Os. This is not a huge thwarting for a broad lens. Not having prototype stabilization makes this lens a 2d pick for run and gun shoots. Using it cameras that have IBIS can provide it with some epitome stabilization.
Control
Manual focus organization
The Sigma 30mm f/i.iv DC HSM Art (Amazon, B&H) has a finite turn ring for its focus ring and tin plow 1 way or the other to a finite degree. Unfortunately for videographers and cinematographers, the Sigma 30mm f/1.4 DC HSM Art is set to focus by wire by default and has no option to switch information technology to fly past wire.
What is the meaning of focus by wire and wing by wire?
Focus past wire: Permit's say you turn the focus ring to alter focus from point A to B. Y'all'd expect the focus to shift accordingly. When y'all stop point B will exist in focus. Now bring the focus point back to A and attempt once again, but at a different speed. Slower or faster, doesn't matter. Now, even if you precisely rotate to the exact aforementioned degree, the focus will not exist on bespeak 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 unlike speed, fifty-fifty slightly, you'll never get the same focus. Avoid focus past wire lenses similar the plague (for video work).
Fly past wire: The distance of focus shifted is directly proportional to the speed at which the ring is turned. This is how a manual focus band is supposed to operate for video and cinematography.
This decision to exclude fly by wire or linear MF by Sigma volition make this lens unsuitable for professional cinematographers and videographers.
Autofocus system
Sigma's autofocus is improving solar day past day, but it is nowhere near the precision and reliability of Canon or Sony's autofocus system. Proceed in mind, that Sigma is a tertiary party lens manufacturer, i.e. they do not make native lenses. Native lenses, such as Sony's FE series and Canon'due south EF and RF series, accept always been better than third party lenses at communicating with their respective cameras.
I practice not recollect anyone will buy a Sigma lens for its autofocus performance.
Basics
Filter Thread
The Sigma 30mm f/1.4 DC HSM Art (Amazon, B&H) has a filter thread of 62mm. This is a slightly uncommon filter size. You may face some trouble trying to find the correct filters.
Build Quality
The majority of the lens exterior is plastic, though the lens doesn't feel cheap.
The optical pattern consists of nine elements in 8 groups, including aspherical lens.
Size and Weight
The Sigma 30mm f/i.4 DC HSM Art (Amazon, B&H) has a bore of 74.2mm and a length of 63.3mm. It weighs around 435 grams. Pretty lite and handy.
Weather resistance
Sigma claims that all their Art lenses are weather resistant. Just again this only holds true if the camera body y'all volition be using is also weather condition sealed. No camera is truly and officially weather condition sealed, and then the best you tin can hope for is reliable weather resistance.
This is an Art series lens and we can wait it to perform as such.
What's in the box
This is what you go in the box (other than the lens):
- Example
- Hood (LH686-01)
While they have omitted the mention of the lens cap and rear cap on their website, I doubt that they will exclude such basic necessities.
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 forepart chemical element in instance of a fall. The hood takes the touch on and shatters, but saves the lens. I'd keep it on unless you take good reason non to.
Alternatives to the Sigma 30mm f/1.4 DC HSM Fine art Lens
In that location is no real alternative to the Sigma 30mm f/i.iv DC HSM Fine art because of its peculiar focal range and it being an APS-C sensor lens.
