Full Frame Coverage of DA Lenses: Comprehensive Test

Which DA lenses cover the full 24x36 mm frame?

By PF Staff in Gear Guides on Jan 7, 2019

In response to the many requests regarding which DA lenses cover the 24x36 mm full frame format ("FF") we have tested almost all DA lenses with a Pentax K-1 under similar circumstances.  We are happy to finally be able to present the full results.

A few DA lenses officially support full frame as stated by Ricoh/Pentax. Those lenses are:

  • DA* 200mm F2.8
  • DA* 300mm F4
  • DA 560mm F5.6

For all the other lenses which we have tested the FF coverage presented in the table below is based on our subjective evaluation of a very large number of test images taken at various apertures, focus settings, and zoom settings, as appropriate. It is highly personal how much vignetting, how much drop in resolution, or how much optical distortion is acceptable, so your mileage may vary. We welcome feedback on our evaluation, but please include photo evidence with any such feedback.

The main flaws generally found with the FF coverage are:

  • black corners, i.e. the lens doesn't cover the FF frame at all
  • heavy vignetting, i.e. the lens covers the FF frame but the vignetting is too heavy to give an acceptable result when corrected in post processing
  • soft corners, i.e. blurry and/or swirly patterns

Announcing "Contrasting Colors" - Our January 2019 Photo Contest

Win prizes in our contest for January 2019

By PF Staff in Photo Contests on Jan 3, 2019

We're herewith announcing our monthly photo contest for January. The theme for this month is "Contrasting Colors".

The theme this month is "Contrasting Colors". However, whereas color theory has precise definitions for contrasting (complementary) colors and their placement on the color wheel, we adopt a more lax definition in this contest and just ask that your image provide some striking, clashing colors. Good luck!

First prize is a $50 gift card to B&H Photo, second prize is a one year forum account upgrade, and third prize is a box of photo paper form Red River.

The official contest rules are found here.

Click here to submit a photo for the contest.

If you haven't done so already we invite you to browse our special gallery of last month's photo contest submissions and nominate your favorites.

Happy New Year 2019!
