some tips for subject isolation ...

I have a pancake 17mm f2.8 mft lens. If i set it wide open to f2.8, and get in close, the subject

is in very sharp focus, but so is the background. Can I get any bokeh with this lens?

What type of lens do you recommend that can deliver very good bokeh, but has other uses too?


to get the most subject isolation with any lens, consider the following tips:

  • use the longest focal length you can (more mm = more background blur)
  • increase subject/background distance (more distance = more background blur)
  • decrease subject/photographer distance (less distance = more background blur)
  • use widest aperture you can (smaller f/# = more background blur)

so using some of these tips, you may see why a 85mm f/1.4 lens can produce a more blurred background than a 14mm f/2.8 lens ... half of the tips involve the lens, the other half involves subject/background/photographer positioning ...

another thing to keep in mind is that a bigger sensor = more background blur ...

good luck with whatever choices you make ...
