Optical Performance
When it comes to optical performance, the Sigma 30mm lens is noted for its ability to deliver excellent image quality thanks to its F1.4 aperture. This makes it particularly adept at low-light situations and allows for shallow depth of field effects.

This capability might be essential for content creators who require quick focus transitions. In comparison, the TTARTISAN 40mm lens includes an STM motor and offers advanced autofocus features like face and eye tracking, providing smooth focus transitions with minimal breathing. While both lenses offer impressive autofocus systems, the TTARTISAN may have the edge in video applications due to its specialized features.
Price Comparison

This means the Sigma lens is about 149% more expensive than its counterpart. For photographers on a budget or those just starting, the TTARTISAN offers an attractive price point without sacrificing too much in terms of performance, making it a more accessible option for many.
Target Audience
The Sigma 30mm lens is ideal for serious photographers and videographers who demand high optical quality and performance, particularly in low-light conditions. Its features and build quality cater to professionals who can appreciate the benefits of a higher price tag. Conversely, the TTARTISAN 40mm lens appeals to enthusiasts and hobbyists looking for a reliable and affordable lens that still delivers great results. Its compact design and lightweight build make it perfect for travel and everyday use.
Which should you buy?
Ultimately, the choice between the Sigma 30mm F1.4 Contemporary DC DN Lens and the TTARTISAN 40mm f2 Lens for Z Mount boils down to individual needs and budget.
