When it comes to vlogging on a full-frame camera, choosing the right lens can make a significant difference in the quality and style of your footage. Today, we’re comparing the Sony 10-18mm f/4 and the Rokinon 14mm f/2.8 AF lenses to help you decide which one best suits your needs for vlogging. Both lenses offer unique strengths, and we’ll be testing them for stabilization, autofocus, and overall usability. Let’s dive into the comparison.
Stabilization Test: Walking and Running
The first test focuses on how stable each lens performs while walking and running, two common movements in vlogs.
Sony 10-18mm f/4
The Sony 10-18mm lens features optical stabilization, which is a major plus when it comes to handheld shooting. During the walking test, it delivered noticeably smoother footage. The wider angle (even though it’s an APS-C lens) gave it a natural advantage in stabilization, making it feel less shaky even during more aggressive movements like running.
Rokinon 14mm f/2.8 AF
The Rokinon 14mm lacks built-in stabilization, which resulted in footage that felt a bit more shaky when walking. While the video was still usable, the shake became more pronounced during the running test. Although the lens was able to keep up, it wasn’t as smooth as the 10-18mm.
Verdict: If stabilization is important for your vlogging setup, the Sony 10-18mm is the better choice. It’s wider, has built-in stabilization, and handles movement more effectively.
Autofocus Performance: Speed and Accuracy
Next, we tested how fast and accurately the autofocus locks onto subjects in a vlogging environment, where switching focus quickly between yourself and the background is essential.
Sony 10-18mm f/4
The autofocus performance on the 10-18mm was quick and reliable, handling the focus shifts between the vlogger and the background well. There was a slight misfocus once, but it was due to the wide-angle nature of the lens—it kept part of the face in the frame when it shouldn’t have. Even with that, the overall speed and accuracy were impressive.
Rokinon 14mm f/2.8 AF
The Rokinon 14mm was a bit slower when it came to switching focus between the subject and the background. It took longer to lock onto the background in comparison to the Sony lens, which could be a drawback if you need to switch focus quickly while vlogging.
Verdict: The Sony 10-18mm lens wins again here, especially for vloggers who need fast and accurate autofocus while moving around or switching scenes frequently.
Image Quality: Field of View and Low Light
Both lenses produce great image quality, but there are key differences in how they handle certain scenarios.
Sony 10-18mm f/4
Since the 10-18mm is an APS-C lens, using it on a full-frame camera in crop mode affects the final image. However, it still offers a very wide field of view, which is perfect for capturing expansive backgrounds or fitting more into your frame when vlogging. The f/4 aperture isn’t the best for low-light situations, but it’s more than capable for well-lit environments, especially if you prioritize smoothness over bokeh.
Rokinon 14mm f/2.8 AF
The Rokinon 14mm f/2.8 lens shines in low-light situations, thanks to its wider aperture. This makes it the better option if you’re shooting in darker environments or if you want to capture astrophotography with beautiful background blur (bokeh). It also has a full-frame design, so you get the full field of view without having to crop, making it ideal for those who want the maximum use of their camera’s sensor.
Verdict: If you’re after low-light performance or creamy bokeh, the Rokinon 14mm is the way to go. For general vlogging, the Sony 10-18mm still holds its own, especially in brighter environments.
Conclusion: Which Lens is Right for You?
Choosing between the Sony 10-18mm f/4 and the Rokinon 14mm f/2.8 AF ultimately comes down to your vlogging style and priorities:
- Go with the Sony 10-18mm f/4 if stabilization, autofocus speed, and a wider field of view are critical for your setup. It’s an excellent option for vlogging, especially if you prioritize smooth footage and shoot in well-lit environments. Plus, it’s the more affordable option, making it a great value.
- Go with the Rokinon 14mm f/2.8 AF if you need superior low-light performance or want to create cinematic bokeh. It’s an excellent choice for creative shots that benefit from a wider aperture and full-frame coverage. However, be prepared to deal with some shake if you’re vlogging on the go.
Both lenses are strong performers, so your decision should be based on your specific needs. If you’re a casual vlogger looking for an affordable, versatile lens, the Sony 10-18mm is likely your best bet. On the other hand, if you need a lens for more professional, low-light situations, the Rokinon 14mm is hard to beat.
