An ultra-wide field of view along with a sleek design, the silver Laowa 11mm f/4.5 FF RL from Venus Optics is a unique wide-angle prime with rectilinear rendering that is ideal for interior, architecture, nature, and landscape applications. The huge 126° angle of view is aided by an advanced optical design, which includes aspherical high refractive index, and low dispersion elements, to realize well-corrected, sharp, and color-accurate imagery. The lens has a manual focus design and permits working with subjects as close as 7.5" away and its built-in petal-shaped hood helps to block stray light from causing unwanted lens flare.

Ultra-wide prime is designed for Leica M-mount rangefinder cameras.

Two aspherical elements and one ultra-high refractive index glass element help to control distortion and spherical aberrations for improved sharpness and accurate rendering.

Three extra-low dispersion elements are used to reduce color fringing and chromatic aberrations in order to produce high clarity and color accuracy.

Impressively wide 126° angle of view pairs with a rectilinear design, which renders subjects with minimal distortion in order to suit landscape and architectural applications. This ultra-wide field of view will exceed that of a rangefinder camera's viewfinder; an external electronic viewfinder or live view method should be used for making accurate compositions.

Rangefinder-coupled for accurate focusing using the camera's viewfinder; despite the lens having a minimum focusing distance of 7.5", the lens/rangefinder is only coupled for accurate focusing to 2.3' and this distance is highlighted on the focusing distance scale. For working between 7.5" and 2.3', live view methods should be used for accurate focusing.

Built-in petal-shaped lens hood helps to prevent stray light from causing lens flare and also offers some physical protection to the lens's front element.

Front of the lens is threaded to accept optional 62mm filters. The lens is also compatible with an optional, dedicated 100mm filter holder.

Five-blade diaphragm produces distinct 10-point sun stars and specular highlights when stopped-down and photographing point light sources.

Q: 5. given that the lens hood is built in, would a 55mm filter with a 52-55 step ring fit?

A: It wouldn't fit due to the lens hood unfortunately.

Q: 6. Other than the Full Frame nature, are there any significant image quality or build quality differences between this and the older 2.8 version that comes in native Fuji mount?

A: This lens is currently the world's widest rectilinear lens. It being a Full Frame lens means it does not suffer the crop of the other lens, and consequently has a much wider field of view. It has a 135° angle of view. This is a significant optical achievement, and really separates it from the older lens.

Q: 7. Which size of Tilta Seamless Focus Gear will fit the focus ring?

Q: 8. what is the country of manufacture?

A: COUNTRY OF ORIGIN CHINA

Q: 9. Is the len hood detachable? Can I use a generic 100mm square filter holder with generic 100m sqaure filter on it? Thanks.

A: The petal-shaped lens hood is built-in, not removable, and not reversible. Unfortunately, this means generic or third-party filter holders won't work. Laowa has a magnetic filter system for the lens coming soon, and it seems that will be the only way to get 4x4" or 4x5.65" size filters to work with the lens.

Q: 10. Will this lens accept a NISI V6 100mm filter holder?

A: It won't work because the hood is not removable so the hood will not allow the filter holder to fit on the adapter ring.
