How to Modify the DA* 60-250mm F4 for Full Frame

By bdery in Articles and Tips on Nov 5, 2017

Pentax’s K-mount has one of the most comprehensive APS-C lens lineups on the market. On the other hand, the digital-era full frame line-up is growing but still small. With the release of the Pentax K-1, many users have taken to testing APS-C lenses to see if they can, in fact, be used on full frame.

With its zoom range, fixed aperture and excellent image quality, the Pentax DA* 60-250mm F4 is a lens that many photographers would have liked to see working on full frame. Sadly, using it in full frame mode without modification leads to dark corners at the wide end and fully black corners at the tele end, as you can see here.

The culprit is a flange on the rear baffle of the lens. Easily accessible, this baffle can be removed, modified or replaced to allow full frame operation.

In this article, we present a step-by-step method to modify the lens, as well as various options to replace the baffle. We also test thoroughly the lens’s optical performance after the modification to evaluate the impact of the change.

Is the modification worth it? Can the 60-250mm be used reliably in full frame mode? Read on to find out!

High-performance full frame telephoto zoom lens

By bdery in Review Announcements on Jun 22, 2017

We reviewed the HD Pentax-D FA 150-450mm F4.5-5.6 ED DC AW on APS-C back in 2015, before the launch of the Pentax K-1 full frame camera. Today we are proud to present an updated version of this review, presenting a defailed performance analysis on full frame. This completes our series of reviews of the current D FA zoom lineup.

The 150-450mm is currently the longest zoom available new for Pentax DSLRs, and has the second longest focal length overall. It has a variable aperture, an extremely rugged, all weather design, a 3x zoom range and an impressive array of external controls. We had been impressed by the lens's capabilities on APS-C.

Review of the Off Road Hiker 30 Backpack by Manfrotto

By bdery in Hands-On Tests on Jun 16, 2017

Some of the advantages of Pentax DSLRs are their ruggedness, weather resistance and generally compact size. Partly because of this, the brand draws quite a following among hikers, campers and the like.

Carrying photo equipment when on a trail is not a simple as on a city street. Luckily, many bag manufacturers have recently begun catering to the needs of outdoors photographers. Bags and backpacks for hiking remain a frequent topic in our Accessories forum and every user has a different opinion. In the near future, we will present reviews of some of the most interesting proposals on the market.

Today we present our first test with the Manfrotto Off Road Hiker 30. Manfrotto is a well-regarded brand in the camera industry, and their backpack offers some interesting and unique features. How does it perform on a trail?

Review of the Everyday Sling Bag by Peak Design

By bdery in Hands-On Tests on Mar 28, 2017

Pentax has long been known for comparatively small camera bodies and lenses. Along with weather sealing, it is one of the highlights of the brand. Cameras like the K-3 and K-S2, in particular, are the smallest of their category.

With the advent of the Pentax K-1 and its lineup of large, fast zooms, things have changed a bit. The K-1 is still relatively small, hardly bigger than the older K20D for instance, but coupled with a 24-70mm or 70-200mm it does take up a lot of room.

Carrying larger equipment presents new challenges with no clear-cut solution. Camera bags are one of the most discussed topic in our Accessories forum, and everyone has an opinion on what is the perfect camera bag.

Today we take a look at Peak Design’s Everyday Sling, a diminutive bag which can still accommodate a surprising amount of gear. How well can it fit a full frame camera and its lenses?
