Am i crap at pics or is IT playing up?. Ive got a 300d with a sigma 80-400 image stabilizer lens on it, the lens went for repair 6weeks ago with a faulty focusing mechanism. I’ve taken some pics today and a lot of them are ok but then i get a run of bad pics that are out of focus, one in particular is a side on of a Hurricane that more or less fills the frame and the camera was set at 250/sec and it came out blurred. On one occasion when i pressed the shutter it fired at a lower shutter speed on its own accord. Thing is i dont really know if its me, the lens or the camera that is causing the blurred pics. The one or the Harrier is blurred and that was stationary. Anybody got any ideas

Whats my..
Hi
Do a test with your camera’s foucus point set to the far most left or right point. Focus on something with the sky behind, once it’s locked keep you finger on the stutter so that it’s still half pressed ie: foucus is locked , move the camera to one side so that the object in focus is now now behind the point of focus , but now the sky is. Your f-stop will have gone from say 8 to 20 plus but the object is still in focus.

Broken?
Hi
No i have is set on all of em, one i cant understand is the stearman pic because the sun was behind me and at 250/sec should’nt have comme out so dark. Here are some that didnt get away
I had a look at the efix data and that photo was shot at 1/250 and the f-stop was 32. I guess here that the camera has locked focus as you panned, but when you took the photo the focus point wasn’t on the aircraft, thus has exposed for the blue sky. To prevent this, use the center focus point and in theory the exposure will always be on the aircraft.
A test to see if the IT is working is to turn it off and see if the shots get better, the same or worse. A while back I thought my 100-400 was playing up, so I turned it off and found out how good it really was. With the IS off, I got all most nothing worth keeping.

Very good shots even if you did have trouble.

Not sure what went on with the stearman pic… :confused:
I still get my share of blurred and out of focus, and I use a Canon 100-400L IS.
I do get more keepers than with a non IS lens, and got even better results since switching to centre point only focus.
For shots in the air, I always set exposure compensation +2/3 too.
It brings out the aircraft better against a bright sky

Have you set the 300D to centre point focus only?
