Today was an excersise in two contrasts. 50mm vs 77mm and dof with only the focus point changing. In addition I was shooting with the crop sensor Pentax K3.
Camera: Pentax K3
Lenses: SMC Pentax FA 50mm f/1.4 75mm effective focal length
smc Pentax-FA 77mm f/1.8 Limited 115mm effective focal length
LENS: 50mm ISO 200 f/8 1/125th
Note the diference on crop below with the 77 Limited
77 Limited ISO 200 f/8 1/125th
I just shot these to contrast the feild of view.
Each of the following two images were shot with the same lens and settings. The only real difference is hoe close the focus poin was. It makes a big difference with the bokeh.
77 LIMITED ISO 200 f/8 1/3200th
77 LIMITED ISO 200 f/1.8 1/2500th
Same settings but moving the focal point makes a big difference in the depth of field.
The rest of the images can be found here.
