An analysis of focus issues on Pentax cameras
By PF Staff in Review Announcements on Feb 2, 2015
The Sigma 18-35mm F1.8 "Art" is an impressive lens. Not only is it the world's first DSLR lens with a fixed aperture of F1.8, but it has also proved to be an optical masterpiece with image quality and bokeh comparable to that of high-end prime lenses.
Unfortunately, in our in-depth review of the 18-35mm, our staff reviewer Heie discovered that the lens suffered from serious autofocus issues while shooting through the viewfinder. These initial findings were verified using five copies of the lens, at different times, across three different K-3 bodies among others. We therefore suspected a problem with how the lens interacts with the camera during phase detect autofocus (PDAF), as no issues were observed in the live view contrast detect autofocus (CDAF).
However, while many user reports agreed with our findings, other users stated that they haven't experienced any autofocus issues whatsoever. Thus, in an attempt to arrive at a more conclusive verdict regarding the 18-35mm's autofocus, our forum administrators decided to test two additional copies of the lens side-by-side. Read on for their findings!
A camera that captures 360-degree images
By PF Staff in Review Announcements on Jan 26, 2015
Today we are happy to present our review of the Ricoh Theta m15, Ricoh Imaging's second-generation 360-degree camera.
The Theta is certainly one of the most intriguing products we've reviewed to date. Its unique capabilities bend the traditional rules of photography and allow users to capture their surroundings and create photos in a brand new way.
You can't go wrong with the Theta's new low price tag, either. Read on to see why we liked this camera so much!

The Internet hasn't given the Pentax K-S1 much love, so we decided to change that by giving it a proper in-depth review. In it, we take a look at not only the face-lifted interface and how the camera handles, but also the image quality from the new 20.2-megapixel sensor.

Several threads on our forum have mentioned The Camera Store's recent Youtube video, which lists the Pentax K-S1 as the worst camera of 2014. We are currently in the process of reviewing the K-S1, and while we might agree that it's the most pointless camera of 2014, it's certainly not the worst.
Why? Because Ricoh has outdone itself with the latest compact, the WG-30w. To sum it up, the WG-30w is a sandbox: a rebadged Pentax Optio WG-2 from early 2012, but with half the LCD resolution, launched to showcase a singular new feature. That feature is built-in Wi-Fi, which ironically works better than the O-FC1 FluCard in a Pentax DSLR.
How could things have gone so wrong? Read on!
A close look at the stylish new Q-mount camera
By PF Staff in Review Announcements on Nov 12, 2014
Today we're happy to be bringing you our in-depth review of the Pentax Q-S1, the stylish new compact mirrorless body from Pentax. While the Q-S1 is virtually identical to the Q7 in terms of hardware and performance, it's gotten an updated look and new colors, so one of the focuses of our review was the build quality and handling. We also discovered a new AF-related feature in the process!
Overall, the Q-S1 turned out to be a fun little camera, just like the other Q-mount bodies. We hope you enjoy the review, and we invite you to download some of the full-size sample photos that we've included at the end.
