19/365 Primes 31mm DOF Test

This is a family room dof test of the 31 Limited.

Camera: Pentax K1

Lens: smc Pentax-FA 31mm f/1.8 Limited

All at ISO 1600.

f/1.8 1/125th

f/2.5 1/80

f/4 1/30th

f/5.6 1/15th

f/11 1/4th

Kind of a boring excersize but I like seeing the dof at the closest focusing distance which by the way is .3 meters or about 11 inches.

If you want to see all the pics between f/1.4 and f/11 go to The 365 Primes Project.

18/365 Primes 14mm Rokinon

It got late today so I decided to photograph my familr room as it nears completion of a remodel. We don't fave it fully decorated yet.

Camera: Pentax K1

Lens: Rokinon 14mm FE14M

ISO 800 f/4 1/50th

ISO 800 f/4 1/30th

ISO 1600 f/4 1/50th

These are all hand held with only the rooms installed lighting at night. This wide lens does help the rooms look larger. The lens has a minimum focusing distance of .28 meters (about 11 inches) The photo of the fabric detail is at .28 meters.

Here is the whole 365 primes photogallery.

17/365 Primes Business Center 14mm

After work I found a business center with some fun glass buildings to shoot. These are all 3 image HDR photographs.

Camera: Pentax K1

Lens: Rokinon 14mm FE14M

ISO 400 f/8 1/100, 1/160, 1/250

ISO 400 f/9 1/60, 1/100, 1/125

ISO 400 f/9 1/25, 1/50, 1/80

Again I note barrel distortion. I'm happy with colors. Still waiting judgement on sharpness.
