Field of View

Same bird, same distance to subject, same lens, different bodies.

Full frame or 135 format on the left, APS-C (1.6x crop) on the right.

    Looks good, can we see it bigger?
  • David de Groot said:
    Bigger than 1176 wide ? With a bit of fidling I could make and upload a larger one. I cheated when making this one and just used the LR Print module to make a two photo contact sheet and then trimmed the extra whitespace ;-)

    thats ok, I get the idea anyhow, hey the 30D did a pretty impressive job and I like how the bird is looking at the camera.
  • Nicole Pearce Photography said:
    oh derr I just clicked on all sizes I'm such a tool lol.
  • David de Groot said:
    hehehe ;-)
    Both did a decent job of focus really given I was at the minimum focus distance for the lens and the birds were silhouetted against the background.

    Score for the 30D!

    Sweet great comparison 1.6X crop is good for the extra reach but then not so great in low light, If only they would make APS-C cams with less pixels squished up and more light sensitive ones.
  • David de Groot said:
    And interestingly, if I crop the 5DII image down to the same field of view, I end up with an image only slightly higher in resolution than the 30D (and I mean slightly, there's only about 100px in both directions difference).
    FF also gives you a more obvious shallow DoF perceptually because you get to see more the out-of-focus region at the edges, even though there's actually no physical difference in the DoF if all other factors stay the same.

    cool... but the bad thing about the cropping is with wide angle lenses on DX format :( lol

    Thanks for these test shoTs
    Seen on your photo stream. (?)
  • David de Groot said:
    Yeah next time I'm out shooting a landscape, I'll do two at 17mm to show the vast difference at the wide end.
  • Jack High said:
    That's a very interesting comparison. Thanks for taking the time and sharing.
  • David de Groot said:
    I'll do another at the wide end at some stage to show the advantage of full frame.
