High-performance, fast full-frame ultra-wide lens
By bdery in Review Announcements on Nov 18, 2018
A newcomer in the photography market, manufacturer Venus Optics has made quite an impression with its growing lineup of lenses with extreme specifications. From macros with enlargement beyond 1:1 to ultra wide lenses, the company tries to do things differently and avoid making what others would consider standard. Thanks to companies like these, the gaps which are left wide-open through partial abandonment of the K-mount by Sigma are being filled by intriguing alternatives.
One such lens is the Laowa 12mm F2.8 rectilinear lens. Laowa is Venus Optics' branding for lenses. This lens is labelled "Zero-D", implying a high level of control over distortion, and offers a rare F2.8 maximum aperture in a full frame format.
Classical camera and lens manufacturers are usually shy about offering ultra wide lenses with such bold claims. Can the Laowa 12mm make a name for itself in a generally conservative market? Read our review to find out!
In-depth review of one of Pentax's finest lenses

We are happy to bring you our in-depth review of the HD Pentax-D FA* 50mm F1.4 SDM AW!
Stakes were high for this long-awaited premium lens. As Pentax's first professional-grade prime for the full-frame format, the D FA* 50mm foreshadows what we'll be seeing in tomorrow's K-mount lineup.
After we put the D FA* 50mm through its paces, we believe that it truly shows that Pentax does not need to fear the competition when it comes to image quality, despite the fact that the company's budget is probably dwarfed by many of its competitors. We are happy to report that this lens scored the highest overall rating of any lens we've reviewed to date! Without further ado:
Evaluation and comparison with the original K-1
By bdery in Review Announcements on Sep 23, 2018
The Pentax K-1, as the first full-frame DSLR from Pentax, changed the K-mount product line forever while becoming an extremely competitive offering within its class. The K-1 Mark II builds on the K-1 and brings exciting new functionality: Dynamic Pixel Shift technology allows you to capture hand-held super resolution photos with more detail than a traditional photo taken on a tripod.
Is the K-1 II a worthy successor to the K-1? Is it worth getting or worth upgrading to? We answer these questions and more in our in-depth comparative review of the K-1 II and K-1.
Widest rectilinar prime lens for Pentax full frame
By bdery in Review Announcements on Aug 1, 2018
Irix is a newcomer in the photography market. The manufacturer seems intent, for the moment at least, on offering high quality wide-angle lenses. The company has a growing user base and its products certainly garner interest. After testing the ultra wide angle Irix 15mm F2.4, we venture even further in extreme wide angle territory with our review of the Irix 11mm F4!
Like the 15mm, the Irix 11mm lenses are offered in two optically identical version. The Firefly is the cheaper variant, with a lighter plastic body, while the Blackstone is definitely more high-end, sporting a metal alloy body, full weather sealing and a few extra perks.
Like its sibling, the Irix 11mm is a full-frame rectilinear lens. Making such a wide focal length rectilinear is impressive (it covers a whopping 126° diagonally). Did the designers manage to preserve optical performance or is the lens too much of a compromise? Being more of a specialized product, user reviews of the 11mm are scarce.
In this in-depth review we try to answer these questions and see just how good the Irix 11mm F4 can be. Is it as good as the company's 15mm? Read on to find out!
