Widen your point of view with the new Irix 11mm f/4 lens!
TH Swiss company is pleased to announce the official launch of the new model of 11mm f/4 Irix lens [Irix 11mm info]. It is another ultra wide-angle rectilinear manual focus lens designed for DSLR cameras. But this time… it’s even wider!
Ingenious functionality of Irix 11mm f/4
To the family of Irix lenses joins a lens with focal length of 11mm and aperture f/4. From the Irix 15mm f/2.4, the Irix 11mm inherited the same, tested and appreciated technological solutions such as:
- extra handy focus lock mechanism,
- extremely useful infinity click feature
- very intuitive and user-friendly hyperfocal scale.
- Rear gelatin filter slot is another common feature of new Irix 11mm f/4.
- Firefly and Blackstone versions
Just like in Irix 15mm, this lens is offered in two finishing versions.
Firefly as a standard version is made of lightweight composite, provided with anti slip rubber coating ring and clearly printed markings.
There will be also a premium version available, which is Blackstone with durable aluminium and magnesium body that ensures foolproof protection of your lens.
Blackstone’s engraved fluorescent markings reflect the UV light to enable easy operation in low-light conditions.
Describing the product packaging, Firefly version will be offered in a set with soft lens pouch, while Blackstone version will be secured in hard lens case. It is also worth mentioning that as with the Irix 15mm, the user gets an additional rear cap in package.
Resistance to extreme weather
All Irix lenses can be used in even the harshest weather conditions. Both versions of 11mm are equipped with a weather sealed construction that protects the interior against dust and moisture. Thanks to inner seals they are also protected from accidental water splashes – two seals are around focus ring and one seal on bayonet mount.
Widen your point of view
As well Blackstone as Firefly versions are offered with identical mechanical and optic construction.
They offer minimal barrel distortion of 3.13% and astonishing diagonal angle of view of 126 degrees.
