TTARTISAN vs Sigma Lens Specs
Sensor format
The TTArtisan 50mm f/1.2 is designed for APS-C sensors, offering a focal length that mimics the human eye perspective on crop-sensor bodies. This makes it a versatile option for photographers using APS-C mirrorless cameras. In contrast, the Sigma 30mm f/1.4 is explicitly labeled as a DC lens, which is Sigma’s designation for APS-C compatible optics. Both lenses target the same sensor size category, ensuring you get the intended image circle without vignetting on APS-C bodies. Neither lens is optimized for full-frame sensors, so your choice depends on your specific camera body rather than sensor coverage differences.
Focal length
You get a 50mm focal length with the TTArtisan, which provides a classic field of view often used for portraits and street photography. This distance offers a natural perspective that is easy for beginners to compose with. The Sigma offers a 30mm focal length, which is wider and better suited for environmental portraits, street scenes, or indoor shooting where space is limited. The 30mm on APS-C also serves as a decent standard lens. Your preference between these two depends on whether you want a tighter, portrait-oriented view or a more versatile, wider field of view for everyday shooting.
Maximum aperture
The TTArtisan features a massive f/1.2 maximum aperture, which is significantly wider than the Sigma’s f/1.4. This larger aperture allows more light to reach the sensor, making the TTArtisan superior in very low-light conditions without needing to raise ISO. It also provides shallower depth of field, creating stronger background blur or bokeh effects for subject isolation. The Sigma’s f/1.4 is still considered a large aperture, offering good low-light performance and background separation. However, the TTArtisan’s f/1.2 spec gives it a clear advantage in light gathering and creative blur potential.
Focus type
Focus control differs significantly between these two lenses. The TTArtisan 50mm f/1.2 is a manual focus lens, meaning you must adjust focus by turning the ring yourself. This requires practice and patience but offers precise control for static subjects. The Sigma 30mm f/1.4 includes a stepping ring motor, enabling autofocus. This allows for faster focusing speeds and better performance with moving subjects, video recording, and general everyday use where quick adjustments are necessary. If you prefer automatic focusing assistance, the Sigma is the practical choice over the manual-only TTArtisan.
Lens mount
Compatibility is determined by your camera’s mount system. The TTArtisan 50mm f/1.2 shown here is built for the Micro Four Thirds mount, fitting cameras from Olympus and Panasonic. The Sigma 30mm f/1.4 is designed for the Sony E-mount, compatible with Sony Alpha mirrorless cameras. These mounts are not interchangeable without adapters, which may affect autofocus functionality. You must choose the lens that matches your specific camera body. If you own a Micro Four Thirds camera, the TTArtisan is the direct option. If you use a Sony E-mount body, the Sigma is the required choice.
Choose your lens based on mount and focus style
Sony E-mount users wanting autofocus
This Sigma lens features a stepping ring motor for reliable autofocus on Sony E-mount bodies. The 30mm focal length provides a natural perspective on APS-C sensors. You get nine rounded aperture blades for smooth background blur. The compact design includes a lens hood and caps, making it ready for immediate use without extra setup.
M4/3 users preferring manual control
The TTArtisan lens is built for Micro Four Thirds mounts with a manual focus ring. Its 50mm focal length offers a classic perspective on crop sensors. The f/1.2 maximum aperture allows for significant light gathering and background separation. The all-metal body weighs 336g, providing a durable and portable option for handheld shooting in various environments.
Photographers prioritizing large aperture
If you need the widest possible aperture, this TTArtisan lens offers f/1.2. This is wider than the Sigma's f/1.4, allowing more light in low conditions. The ten diaphragm blades help create distinct bokeh. While it requires manual focusing, the large aperture is ideal for portraits or low-light scenes where autofocus might struggle or where creative control is preferred.
