What is the Sigma 17-70mm good for?

The Sigma 17-70mm f/2.8-4 DC Macro OS Lens features a great general purpose focal length range, short minimum focus distance, HSM autofocus and OS (optical stabilization) in a well-built and very affordable lens.

What is Macro HSM?

5-6.3 DC Macro OS HSM is Sigma’s latest super-zoom for APS-C SLRs, distinguished from the previous version by the addition of ‘Macro’ to its name. It’s is one of the best lenses of its type, with decent optics, fast autofocus and effective image stabilization.

Is Sigma 17-70mm full frame?

The Sigma 17-70 f2. 8-4 DC Macro OS HSM C Canon is a “standard” zoom lens for APS-C cameras, in this case Canon. It is also available for Nikon and Sigma APS-C bodies. It covers the range 17mm to 70mm, the relative focal length for full frame 35mm would be 27.2mm to 112mm.

What is a Sigma lens used for?

Sigma Art lenses are perfect for a long list of photography types and shots – including portrait, macro / close-up, landscape, still life, underwater, architecture, commercial, corporate, and studio photography.

What is DC Macro lens?

5-6.3 DC Macro OS HSM has been built with Sigma’s exclusive Optical Stabilizer (OS) function. This provides approximately 4-stops of effective camera correction, allowing for lower-light shooting, or greater sharpness in adequate lighting situations.

What is HSM Sigma?

The Hyper Sonic Motor (HSM) is an original SIGMA development that uses ultrasonic waves to drive the autofocus mechanism. Its extremely quiet operation helps avoid disturbing photographic subjects. High torque and speed assure rapid autofocus response. SIGMA uses two types of HSM: ring HSM and micro HSM.

What does OS mean on a camera lens?

Optical Stabilizer
SIGMA’s original OS (Optical Stabilizer) function uses sensors inside the lens to detect any motion, then moves specific lens elements in order to effectively minimize blur caused by such movement.

What is a 18 250mm lens good for?

Covering wide angle 18mm to telephoto 250mm, this versatile lens designed exclusively for digital SLR cameras, is suitable for all-purpose photography including landscape, sport, and macro photography.

What does OS mean on my Sigma lens?

What is OS setting on Sigma lens?

Sigma lenses with “OS” in the name include this technology which employs motion sensors to control floating lens groups to counteract camera movements which can cause undesirable blur from hand-holding shots with slower shutter speeds.

What is OS setting on lens?

SIGMA’s original OS (Optical Stabilizer) function uses sensors inside the lens to detect any motion, then moves specific lens elements in order to effectively minimize blur caused by such movement.

What does OS stand for in camera shots?

When activated, the Optical Stabilization technology inside a Sigma lens senses slight motions of the camera and lens combination in the photographer’s grip and sends signals to the OS system’s floating lens group to cancel out the movement with an opposite reaction.

What is HSM autofocus?

For those unfamiliar with the numerous lens acronyms, HSM stands for Hyper Sonic Motor, (also known as Ultrasonic motor, Silent Wave Motor or even Sonic Direct-drive Motor) and is a faster, quieter and often more compact motor system for lenses. Essentially this should mean quieter and faster focusing.

What does Sigma HSM mean?

What does OS mean on a Sigma lens?

SIGMA’s original OS (Optical Stabilizer) function uses sensors inside the lens to detect any motion, then moves specific lens elements in order to effectively minimize blur caused by such movement. Owing to the stabilized image in the viewfinder, it is possible to fine-tune composition and ensure accurate focusing.

What does HSM stand for?

A hardware security module (HSM) is a physical device that provides extra security for sensitive data. This type of device is used to provision cryptographic keys for critical functions such as encryption, decryption and authentication for the use of applications, identities and databases.

What is the Sigma 17-70mm macro OS HSM?

The Sigma 17-70mm F2.8-4 DC Macro OS HSM is a premium fast ‘normal’ zoom for APS-C SLRs, which is designed as an upgrade for photographers who have outgrown the ‘kit’ zooms typically supplied with camera bodies.

Not so sure they would help Sigma. I just came back from my holiday where I was shooting exclusively with this lens. I actually bought it for this holiday. Now, after converting from RAW and analysing several K of photos, I can confirm that 17mm is a bit more problematic than it was with original 17-70.

Is the Sigma 17-70mm a good lens?

Prior to this Sigma made the unstabilised 17-70mm f/2.8-4.5 DC, a lens which was very highly regarded in its time. The latest 17-70mm offers some pretty clear advantages over the average 18-55mm F3.5-5.6 kit lens.
