    Default argh focusing - added pics to post #3

    Hi ladies, I haven't been around much recently just occasional replies here and there but no posting pictures. After my get together with Andrea I go so sick I had no energy and that was almost a month ago haha crazy. Anyway we went to the zoo yesterday and for the first time since the meetup I took pictures and was looking at them last night. I'm so frustrated with focusing, most are ruined My ap was open perhaps too much but it wasn't fully open. I was using auto focus and I put the spot right on Evan's eye so why the heck are his eyes oof?!?!?!? Not always but enough that most of the pictures are ruined

    ok don't mind the comp or anything haha

    I just realized my iso was higher than I intended (silly me forgot to fix)
    iso400 f/2.8 ss 1/250 35mm ......my lens goes opens to 1.8 so I'm not quite fully open, I realize as a newbie I maybe should open up more I just didn't think if Evan was barely moving, i'm close enough get the focus box fully in his eye that I'd still have so many problems dh thinks there's nothing wrong with the focus but he also doesn't have a problem with photostudio pinlights haha
    sorry I didn't sharpen for web and they seem a tiny more oof than in ps



    same just cropped so I could should his face/eyes closer

    It does look like the focus fell on the plane a bit in front of his eyes - hair and nose both look in focus to me.

    I would probably try closing down the ap just a little bit more - to 2.2 or so or maybe even 3.0 just until you get a feel for how it focuses.

    Also, what focus point were you using? I find that my "outside" focus points are less accurate, so I close down my ap a stop or two when using them.

    Just some thoughts. Hope it helps.

    I was curious do you toggle your AF points on your camera to set the focus on the subjects' eyes?

    Yeah...focus fell just infront of the eye. Lots of little spots on cheeks, nose, forehead in focus.

    Which lens were you using? Which focal point were you using? Did you focus and re-compose?

    I was using 2.8, my lens goes to 1.8 but I was trying to stay a little away from that, I could def try closing a bit more

    I was using my 35mm f/1.8 lens, af-area set to dynamic area, metering set to center weighted. My camera has three focus spots one in the centre and two on either side. I had it using the centre spot. I put the focus point right over his eye. After focusing I honestly don't remember, I might have moved a little bit since his eye isn't dead centre. I guess if I did that the ap is open enough that a small shift would still mean oof duh, argh


    Amber in your siggy pic what was lens/ap was that?

    For my siggy pic I used my 70-200mm 2.8 USM IS L lens and the settings were:

    Exposure: 0.003 sec (1/320)
    Aperture: f/3.2
    Focal Length: 75 mm

    I think in this instance, a more closed aperture would have been appropriate...seeing how oof his ears are tells you how shallow the DOF was. Remember that the closer you are to your subject, the smaller the depth of field. If you're close to your subject and working with a really shallow depth of field and also using focus and re-compose, it is really easy to miss the focus just slightly.

    However...do keep an eye on your photos...look to see if they are consistantly front focused. If you get the same error over and over, it is possible that your lens (or your camera) are off. You can learn to compensate for those things over time or get them repaired.

    My Tamron is a good little lens, but if I use any of my outer focal points with that lens...I get backfocusing. I know this now, so for that lens I focus and re-compose. For my 70-200 lens, it works great with the outer focal points but miserably when I try to focus and re-compose. Once you learn how each piece of equipment you has works best, your shots will improve.
