4. Ovládání objektivu

4.1 Automatické ostření (AF)

The lens features an STM (Stepping Motor) for quick, quiet, and precise autofocus performance. It supports full-time manual focus override, allowing you to fine-tune focus even in AF mode. The internal focusing design maintains the overall lens length during use, contributing to improved handling and quicker response.

The lens supports accurate eye-tracking autofocus for real-time tracking of moving subjects.

For video recording, the STM motor operates quietly. However, when adjusting the aperture ring in video mode, the aperture blades may produce audible noise, especially between f/5.6 and f/16, which can be picked up by the camera's internal microphone. This can be mitigated by using an external microphone.

When pulling focus between two objects in video, the autofocus speed may feel too quick for a cinematic look and can sometimes stutter before settling on the focus point. Additionally, if the camera is moved very close to the minimum focusing distance and then moved away, the continuous autofocus may struggle to re-acquire focus, resulting in blurred footage. Manual focusing is recommended for precise focus pulls in video.

4.2 Manuální ostření (MF)

The focus ring is designed to be buttery smooth, providing excellent tactile feedback for manual focusing. For enhanced control, especially in video, you can adjust the focus ring operation in your camera's menu settings from 'Nonlinear' to 'Linear'. This setting is typically available on newer Fujifilm models (e.g., X-H1, X-T3, X-T4).

4.3 Ovládání clony

The lens features an integrated manual aperture ring. You can set the aperture manually or select the 'A' position for automated, camera-based aperture selection. The aperture ring is clickless, which allows for smooth, gradual changes in exposure during video recording without the hard stops found on clicked aperture rings. This is beneficial for achieving seamless exposure transitions.

The aperture ring is light to the touch and turns freely. It remains clickless until f/16, where a click confirms engagement of the auto aperture mode.

4.4 Kvalita obrazu

The VILTROX 23mm f/1.4 lens is constructed with 11 optical elements in 10 groups, including two extra-low dispersion (ED) elements and two high refractive index elements. These elements, combined with HD Nano multilayer coating, work to reduce color fringing, chromatic aberrations, spherical aberrations, and distortion, ensuring high clarity and accurate color rendering.

The 9-blade circular aperture contributes to smooth and pleasinefekt bokeh.

The 9-blade circular aperture produces excellent resolution and soft, pleasing out-of-focus blur (bokeh). The lens demonstrates impressive sharpness, particularly at f/1.4, both in the center and towards the edges of the frame.

A slight vignette may be present from f/1.4 through to approximately f/3.6. This can often be corrected in post-production using lens correction profiles available on the VILTROX website. Significant flare can occur when shooting directly towards a strong light source like the sun. Chromatic aberration (fringing) is generally well-controlled and kept to a minimum above f/2.8, and any minor instances can typically be removed in post-processing.
