Advances in Digital Zoom Technology Breathe New Life into Shorter Lenses


Advances in digital zoom technology have significantly transformed the landscape of photography, particularly for users of shorter lenses. Though not heavily marketed, the digital zoom feature found in many recent camera models is a game-changer. Since its inception in the mid-2010s, this technology has evolved from its rudimentary beginnings to a robust option that photographers can utilize with confidence.

In the early stages, digital zoom capabilities were often criticized for their lack of quality. Initially, they merely enlarged a segment of the sensor’s data, which frequently resulted in images riddled with artifacts and poor detail. Unfortunately, this initial reputation still lingers in some circles, causing hesitation among photographers regarding the value of digital zoom technology. However, recent advancements have breathed new life into this feature, transforming it from a mere novelty into a powerful tool for creative expression.

Today’s manufacturers are keenly aware of these past shortcomings and are improving their offerings. Companies such as Fujifilm and OM System, previously known as Olympus, are at the forefront of this innovation. They’ve refined their JPEG processing engines to enable cameras to produce cropped and upscaled JPEGs with remarkable quality. These systems often come equipped with selectable magnification factors—such as 1.4x and 2x—that broaden the creative possibilities for photographers, particularly for those using shorter focal length lenses.

Take the OM System OM-1 Mark II as an illustrative example. This camera boasts a built-in digital teleconverter that outputs cropped JPEG images at a 2x magnification. The quality of these JPEG images is impressive, primarily due to effective in-camera sharpening and noise reduction methods employed by the camera’s processing algorithms. This feature allows photographers to extend the reach of shorter lenses significantly. For instance, pairing the OM System M.Zuiko 75–300mm f/4.8–6.7 II Micro Four Thirds lens with the OM-1 Mark II delivers an effective focal length of 600mm. When engaged, the digital 2x converter enhances this reach to a striking 1,200mm, effectively bridging the gap between standard and professional gear.

While it’s true that the image quality produced by these digital converters may not entirely rival that of high-end professional telephoto lenses—many of which can cost hundreds or even thousands of dollars more—the output can still meet the demands of social media and web display admirably. For photographers who create content for digital platforms, the distinctions in quality often diminish when images are resized or compressed. Even seasoned photographers who own both professional lenses and digital converters recognize that, upon posting online, the superior resolution of more expensive optics can become less noticeable when viewed on smaller screens.

Testing the capabilities of this innovative setup is straightforward, particularly for those equipped with both the OM-1 Mark II and the OM System 75–300mm f/4.8–6.7 II lens. To observe the full potential of the 1,200mm telephoto feature, photographers can follow these simple steps:

1. Set the JPEG quality to Large Super Fine (LSF), as RAW format is not supported when using the digital teleconverter.
2. Adjust the ISO to the lowest acceptable setting for the prevailing light conditions.
3. Navigate to the M2 camera menu, specifically the second screen.
4. Enable the Digital Teleconverter function.
5. At this point, the viewfinder or LCD will show the final 1,200mm JPEG output.

While the f/6.7 maximum aperture of this setup does necessitate adequate lighting—making lower ISOs preferable—results are often satisfactory straight from the camera. Should noise become an issue, post-processing with denoising software, such as Topaz, can rectify the situation and enhance the final images.

For those eager to see the results, numerous examples of 1,200mm shots captured with this setup at a local park are available. These were taken during favorable lighting conditions at ISO 200, and the OM-1 Mark II processed them to a resolution of 5,184 by 3,888 pixels. Through Photoshop, the images were resized to 1,200 by 900 pixels at 72 dpi—perfect for web display. The results illustrate the remarkable sharpness and detail achievable at the extended focal length of 1,200mm.

As digital zoom technology continues to advance, it provides photographers at all levels with new opportunities to explore their creativity and enhance their work. Whether you’re a hobbyist or a seasoned professional, understanding and effectively utilizing digital teleconverters can render a new range of possibilities, potentially affecting the way images are captured and shared. The evolution of this technology signifies a noteworthy step forward, enabling shorter lenses to achieve longer reach and greater versatility in capturing the world around us.

In summary, the advancements in digital zoom technology have transformed how photographers interact with their equipment. By enhancing the functionality of shorter lenses, manufacturers like OM System and Fujifilm have made it possible for photographers to extend their reach without the financial burden of investing in high-end telephoto lenses. As more photographers become aware of these capabilities and experiment with them, the standard practice of photography is likely to undergo significant changes. The future of digital zoom undoubtedly holds exciting potential, and it’s an exciting time to be a part of this evolving landscape.
