View Full Version : Zuiko lens and Shallow DOF

29th June 2010, 09:10 PM
I have been using my 12-60 over the weekend and took a candid picture of his couple:

http://e-group.uk.net/gallery/data/500/60mm_f4.jpg (http://e-group.uk.net/gallery/showphoto.php/photo/25220)

The lens was at the 60mm @ f4. Ok now i know that f4 is not that wide but I was a little disappointed in the result. I was hoping for the couple to stand out more from the background.

Question is how to achieve this, with out having to use Photoshop or something else?

Maybe I should have used the 50mm I had and opened it up to f2.8?
Or is there a 3/4 lens that would give me that very shallow DOF I am after?

Suppose I should stop shooting film with fast primes and wanting the same kind of look :confused:*yes:)

Well, the ways to get a shallower DoF are open up the aperture (which you have done as far as possible with the 12-60mm at 60mm), get closer (intruding on couples personal space and ruining the candid shot), use a longer lens or use a FF camera (not an Oly digital option).

That's it I'm afraid without falling back on Photoshop.

dof control is a function of aperture and magnification - the latter being a function of subject distance and focal length.

it's simple physics and online calculators such as http://www.dofmaster.com/dofjs.html will give you a feel for the numbers/combinations.

relatively shallow dof with 43 cameras isn't a problem - here's one from a set a few weeks ago

The bigger the aperture (lower f number) the shallower the depth of field. Also, often better effects can be achieved when you are closer to the subject. If you can do both i.e. large aperture and get close to your subject you will get ever reducing depth of field.

Yes, I think you would need to change up a gear to one of the ferociously expensive top pro 4/3 f2 lenses like the 35-100 .. or use a longer legacy tele such as a 200mm f3.5 Tamron. Either way you run the risk of drawing attention to yourself :)

Cheaper alternatives to the top grade zooms would be to get a Zukio 50 mm F2 or a Sigma 30 mm F1.4 for when you want shallow DOF. I carry the 50 mm F2 for that purpose.
