"Portrait shots with a D3100 18-55mm and/or 55-300mm"


Wellesley, CA
          

Hi I am new to SLR cameras and got a D3100 with the D3100 18-55mm and 55-300mm lenses which I haven't had much of a chance to play around with yet but I was wondering. Without getting a 35mm or 50mm 1.8/1.4 lens, am i able to take pictures with blurry backgrounds similar to that of using the lenses mentioned above? When I am in guide and i go to soften backgrounds it only lets me put the Ap down to 6.5 for some reason.. does it matter where I have the zoom set when I change the app? sorry if this is a dumb question, i am THAT new.

Thanks,

Sarah

Both of your lenses are variable aperture lenses. This means that the maximum aperture gets smaller as you zoom from wide to narrow. For example, your 18-55mm f/3.5-5.6 lens starts at f/3.5 for 18mm and slides to f/5.6 as you zoom to 55mm. (It gets to f/5.6 probably about half way there, say 35mm or so.) Similarly for your 55-300mm f/4.5-5.6 lens.

Since neither of these lenses will let you get anywhere near the f/1.8 of the primes you mention, you will need to increase the distance from your subject to the background to get the nicely blurred backgrounds you are looking for.

Then how far from the subject should I be?

The distance from camera to subject is an experimentation. The bigger the difference between camera-subject and subject-background the more blurred the background will be. However, if you use a wide angle lens to get really close to your subject, you will get some distortion in the view of the body parts. On DX cameras, 50mm is a good starting point for portrait lens length.
