[Key features]

  • I seriesPremium Compact Primes for mirrorless users

The SIGMA I series features full-frame-compatible lenses that offer mirrorless users a new and better alternative, both in the experience of shooting with the lens and in the impressive results it is able to achieve.

One of the key advantages of mirrorless cameras is their smaller form-factor, and this new 24mm optic is designed to be perfectly matched to these more compact systems without sacrificing performance. This combination of superb optical quality with exceptional portability, not previously possible with DSLR systems, will bring new opportunities to this and future generations of photographers.

Simultaneously, SIGMA is aware that, in this day and age when we have such huge diversity when it comes to what we use to photograph, as represented by smartphones, people look for something more than a mere act of "taking pictures" when they choose to own a camera and lenses.

SIGMA's excellence in development and processing technologies has been built up since it was founded in 1961, and has become further sophisticated with the introduction of the SIGMA Global Vision in 2012. With this as a base SIGMA has given careful thought to how photographers use and enjoy their lenses, including optical design, advanced functionality, build quality and the experience of picking up and using the lens, and with all of this carefully considered the I series was born.

  • New standards of optical performance for the Contemporary line

The SIGMA 24mm F2 DG DN | Contemporary, like the SIGMA 35mm F2 DG DN | Contemporary and the SIGMA 65mm F2 DG DN | Contemporary, combines the highest level of optical performance even at its maximum aperture of F2 and a well-balanced body.

The lens uses two SLD glass elements and one FLD glass element to correct axial chromatic aberration, which is a particular concern with bright lenses. It also incorporates two high-precision glass-molded aspherical elements, made possible by the processing technology of SIGMA's sole production facility in Aizu. This has enabled the total number of lens elements to be kept down and the size and weight of the lens to be reduced, while providing excellent correction of various aberrations.

In anticipation of wide-angle lens applications, SIGMA’s optical designers have ensured the lens resolution is extremely high, and is uniform from the center to the periphery of the image. Sagittal coma flare is also well suppressed, giving the lens a high degree of rendering power that makes it ideal for night sky photography.

The AF drive system incorporates a quiet, high-speed stepping motor. This allows photographers to capture every detail of the spacious 24mm scene with light AF.

  • Exceptional I series build quality with a compact form-factor

All I series lenses have an all-metal construction. The precision-cut aluminum parts not only give the barrel a sleek, stylish finish, but provide superb durability that improves the quality of the entire product. Metal materials are also used in internal structures that slide with the operation ring for added robustness. These high-precision components crafted with SIGMA’s cutting-edge metalworking technology are also used in SIGMA’s cine lens line-up for professional cinematographers and provide a tactile, ergonomic feel that make the lens a pleasure to use.

The cover ring between the focus ring and the aperture ring has hairline processing that is also used for the rear cylinder of the Art line. This covering functions as a finger hold when attaching or detaching the lens.

    Impressed by the artistry and precision of the Sigma 24mm F2truly a lens that fuels creative freedom and storytelling. Im proficient in diagnosing and repairing tech issues. Just as clarity is essential in photography, its equally vital in cybersecuritydiscover how to spot fake Microsoft alerts in our latest blog: How to Identify and Avoid Bogus Microsoft Security Alerts and Find Genuine Support.

    In todays digital age, security alerts from Microsoft are a crucial part of keeping your system safe from potential threats. However, not all alerts are legitimate. Many cybercriminals use bogus microsoft security alert as a tactic to trick users into downloading malware or providing sensitive personal information. These fake alerts often appear as pop-up messages on your computer screen, warning you about supposed issues with your system or security settings. Recognizing these fraudulent messages and knowing how to protect yourself is essential in avoiding falling victim to scams. If you're ever uncertain, it's important to know the right Microsoft support number to call for legitimate help.

    Spotting Bogus security alert microsoft
    A security alert from Microsoft should typically be informative and relevant, without overwhelming language or urging you to take immediate, drastic action. Bogus Microsoft security alerts, on the other hand, often have red flags that can help you spot them as fraudulent:

    Urgency and Threats: Fake alerts often employ scare tactics, claiming that your computer has been compromised, your data is at risk, or that you need to act immediately. Genuine Microsoft alerts will not use such pressure tactics.

    Suspicious Links or Phone Numbers: Many bogus alerts will ask you to call a number or click on a link to resolve an issue. These links often lead to malicious websites or install harmful software. Microsoft will never ask you to contact them directly through an unsolicited pop-up message.

    Typos and Poor Grammar: Scammers often dont pay attention to detail, so look for errors in spelling, grammar, and formatting. Official Microsoft security alerts are professionally written and contain no such mistakes.

    Too Good to Be True Offers: Fake alerts might promise free software or fixes for problems you didnt even know you had. Real Microsoft security measures do not offer too good to be true deals.

    Asking for Personal Information: A bogus Microsoft security alert might prompt you to enter personal information such as passwords, credit card numbers, or other sensitive data. Official Microsoft notifications will never ask for this type of information via a pop-up message.

    If you encounter such an alert, avoid clicking on any links or calling any phone numbers provided. Instead, close the message and run a full scan with your antivirus software to ensure your system is secure.

    What to Do If You Receive a Bogus Alert
    If you believe you have received a bogus Microsoft security alert, its important to follow these steps to secure your system:

    Do Not Interact with the Alert: As tempting as it may be, do not click on any links, open attachments, or call any numbers from the alert. Interacting with these alerts can lead to malicious software being installed on your computer.

    Close the Alert: If the alert is a pop-up, close it immediately by clicking the X button at the top corner or by using Ctrl + Alt + Delete to open the Task Manager and end the suspicious task.

    Run Antivirus Software: Use your antivirus program to scan your computer for potential threats. Many reputable antivirus programs can detect and remove any malicious software that might have been installed by these bogus alerts.

    Clear Your Browser Cache and History: Fake alerts may be associated with malicious websites or pop-up ads. Clearing your browser history and cache can help remove any traces of these sites.

    Update Your Software: Ensure that your operating system and software are fully updated. Microsoft regularly releases updates to patch security vulnerabilities, and having the latest versions of software can help prevent attacks.

    How to Contact Genuine Microsoft Support
    In some cases, you may find that your computer has been compromised, or you may still have doubts about whether an alert is real. In these situations, its important to know the right way to contact Microsoft support. The Microsoft support number is the best way to get in touch with their official customer service team.

    However, avoid searching for the microsoft support number through Google or following phone numbers provided by suspicious pop-ups or emails. Scammers often set up fake support pages with phone numbers that lead directly to their own call centers. Instead, go directly to the official Microsoft website to find their contact information. You can visit the Microsoft Support page and navigate to the Contact Support section, where you can find live chat options, call-back services, or other methods for getting in touch.

    If you are unsure whether a number youve found is legitimate, its always safer to go directly to Microsofts official site and avoid relying on third-party sources that might be fraudulent.

    Additional Security Tips to Avoid Scams
    Aside from recognizing bogus Microsoft security alerts, there are other ways you can protect yourself from scams and cyber threats:

    Enable Two-Factor Authentication: This adds an extra layer of security to your Microsoft account. Even if someone gains access to your password, theyll need the second factor (such as a code sent to your phone) to access your account.

    Use Strong, Unique Passwords: Avoid using easily guessable passwords for your accounts. Consider using a password manager to generate and store strong, unique passwords for each of your accounts.

    Keep Your Software Updated: As mentioned earlier, software updates often include patches for security vulnerabilities. Make sure that your operating system, apps, and antivirus software are all up to date.

    Avoid Public Wi-Fi for Sensitive Transactions: Public Wi-Fi networks are less secure, and hackers can exploit them to steal data. Avoid accessing sensitive information or making financial transactions while connected to public Wi-Fi.

    Educate Yourself on Phishing Attacks: Learn how to identify phishing emails and other types of scams. Phishing attacks often come in the form of fake emails or websites designed to trick you into providing personal information.

    Conclusion
    In todays digital world, the threat of bogus Microsoft security alerts is a real concern. Scammers often exploit users trust in well-known brands like Microsoft to deceive them into installing malware or stealing personal data. By staying vigilant and learning how to spot these fake alerts, you can protect yourself from becoming a victim. If you ever have any doubts, always rely on the Microsoft support number found on the official Microsoft website for help. Remember, legitimate alerts will not demand immediate action or personal information, so always take the time to verify before making any decisions. By following these simple guidelines and remaining cautious, you can ensure that your digital security remains intact and avoid the risks posed by bogus Microsoft security alerts.
