Comparing "Bokeh" on Nikon, Sigma and Fuji lenses


Which camera and lens took this first photo?  Here are the choices

  1. Nikon D4, Nikon 85mm f/1.4 AF-D [Lens $969]
  2. Nikon D4, Sigma 70-200mm f/2.8 EX DG APO OS HSM [Lens $1249]
  3. Nikon D4, Sigma 120-300 mm f/2.8 DG EX APO IF HSM [Lens $2500]
  4. Nikon D4, Sigma 120-300 mm f/2.8 DG EX APO IF HSM, with Sigma 1.4 converter [converter $249]
  5. Nikon D4, AF-S NIKKOR 28-300mm f/3.5-5.6G ED VR [Lens $897]
  6. Fujifilm X-E2, FUJINON XF 55-200mm f/3.5-4.8 R LM OIS [Lens $699]
  7. Fujifilm X-E2, FUJINON XF 18-55mm f/2.8-4 OIS Zoom [Lens $694]
It might surprise you. For this exercise I shot each lens wide open and at the longest focal length and the closest distance that the lens would focus. Now there is a slight focus issue due to my skills of placing the tripod and subject, but you can see for yourself and pick the photo that matches the above photo.

Nikon D4, Nikon 85mm f/1.4 AF-D

Nikon D4, AF-S NIKKOR 28-300mm f/3.5-5.6G ED VR

Nikon D4, Sigma 120-300 mm f/2.8 DG EX APO IF HSM

Nikon D4, Sigma 120-300 mm f/2.8 DG EX APO IF HSM, with Sigma 1.4 converter

Nikon D4, Sigma 70-200mm f/2.8 EX DG APO OS HSM

Fujifilm X-E2, FUJINON XF 18-55mm f/2.8-4 OIS Zoom Lens

Fujifilm X-E2, FUJINON XF 55-200mm f/3.5-4.8 R LM OIS Lens
If you had a hard time figuring out the top photo it is the Fujifilm X-E2 with the FUJINON XF 55-200mm f/3.5-4.8 R LM OIS Lens.

When I photograph people for portraits I love the Nikkor 85mm f/1.4 AF-D.  While I can get closer with many other lenses as you can see above, any closer with the 85mm you are too close.

I hope this exercise also points out that using a longer lens can give great "BOKEH" if you back up a little and zoom in all the way.

The one lens that really wasn't all that great was the FUJINON XF 18-55mm f/2.8-4 OIS Zoom because zoomed all the way in at 55mm the ƒ/4 is just too much depth of field.  I think if I had the Fujinon XF 55mm ƒ/1.2 then I would see something similar to the 85mm ƒ/1.4.

The lesson I hope is that you might try some longer lenses for portraits to get some smooth silky "Bokeh".
