  • Focussing on Toby (in a darkened room).

    Sometimes we do things out of boredom or just don't find something better to do. Anyhow, here is our black dog Toby sitting on a dark grey couch in a dimly lit room & I am using three different cameras with the focus assist LED ON with each of them to compare how each can get focus OK (only using CD-AF as PD-AF struggles too much using my 4/3's lenses in these conditions) with each having been exposed for 1/4 second.

    The first is the E-M1 with the 75-300 lens at 75mm (cropped a little & at ISO 6400 NF Standard).


    The second is the E-M5 with the 12-50 lens at 50mm (cropped more & at ISO 6400, NF Standard).


    And the third is the Stylus 1 at 38.6mm f2.8 (zoomed in & at ISO 1600, NF Sandard).


    Then Toby is saying, "How much longer do I have to sit here for you?"

    E-M1 +75-300 lens at 75mm with clip on flash.

    I am impressed with how good the contrast detect AF is in dark scenes (on all three cameras) & with a bit of a struggle these mostly locked onto focus. The obvious key to low light photography is to use a bright (large aperture) lens. I'm waiting for when I can get my hands on the 40-150 f/2.8 lens, but funds won't allow me to do that until next year some time, hopefully when the prices are a little lower & they are offering a cash back deal (like they are doing for us here right now on cameras & lenses).

    Thanks for indulging me & looking.

    An interesting experiment......worth doing if only to gain confidence when faced with a real life situation when you need to photograph in such conditions.

      Thanks. Yes, it's worth knowing where the limits are with each camera/lens combination.

        If these pictures are OOC Jpegs then you would be able to get a few extra stops if you used RAW files to start work with on the computer.

          I always save RAW as well so I do have that option.

            Ross with so many dark tones I'm surprised these underexposed so much with auto metering!
            Regards Paul.
            One day I hope to be the person my dogs think I am.

              But it was a fairly dark end of the room & the photos tell what the light was actually like reasonably well (& with all 3 cameras), hence my trialling AF in darkish conditions of a dark subject & the Contrast Detect works pretty good in these types of conditions. If I tried to use the 14-54 II lens on the E-M1 using PD-AF (with formware 1.4) it just couldn't cope but on the E-M5 using CD-AF it was OK, within reason as the above (photos) didn't find focus every time instantly.
