When I pan and the sun gets in the frame the camera sometimes (well... always) locks up. I get an 00 aperture and everything just freezes. Switch off-switch back on and the problem is gone.

But this is annoying, especially when I have to wait 20 min. for the next plane, and when it shows up the camera freezes again (Helsinki is no JFK. If I'm at the airport all day, I see 1 departing MD11, and if I'm lucky, another one returning)

Sounds like a bug in the firmware? Has anyone upgraded the firmware and are you happy with the upgrade? Remember the website address? Thank you.

Did you try asking this question in the Canon SLR forum at DPreview.com?

I've seen this problem once or twice with the 100-400mm - ie. panning the aircraft, and at a certain point lens & camera stop talking. Now I thought the reason for this is that I had the camera on AF Servo and had changed the zoom while the camera was shifting focus.

I'm sure the manual advises not to change focal length while the camera is actively focusing, so I put it down to "user error". I can't recall whether or not my pan incorporated a point towards the sun, so can't say whether or not this is also a factor.

So my question is what lens are you using, and are you zooming while panning? Is the sun getting in the lens coincidental?

If you are sure it IS the sun exposure that is the problem, my best guess is that whatever program you are using, the burst of light is perhaps exceeding that program's parameters - eg. you're using TV and selected a speed of 1/100th and the burst of light causes the camera to try and set an aperture of, say f60 - I could imagine that exceeding the allowed range in certain circumstance might cause a temporary lock up.

Incidentaly I had the lastest firmware installed when I noticed this problem, so I doubt this is possible solution.

As I've only seen this occur a couple of times, and put it down to user error, I didn't worry about it - but now I will try and reproduce the problem in a controlled fashion ... if the sun ever shines again!

Cheers,

Colin

The problem occurs with the 100-400mm lens. I pan, and also change the zoom factor, but usually use the Av program. The camera locked up at least ten times and I think the common factor was the sun getting in the frame.

I don't use the AF servo, it's not quick enough. I use autofocus, quickly reframe and take the picture. In some ways this is a toy camera compared to the EOS-3 and 1n, which I've used before. ie. the autofocus is slow and hunts a lot in low light situations.

But the superb quality of the pictures make up for its shortcomings. Plus the fact that I don't have to do a lot of scanning or retouching (dust and scratches) in photoshop anymore.

It's also nice to shoot 500 pictures at full resolution and not have to worry about film/slide development costs.

And to clickhappy: No haven't tried that yet but will give it a go when I have the time. But thanks for the tip.

Peter,

You seem to be using the same combo I am. Still I haven't ever had this "00" aperture problem. Have you tried cleaning the contacts of lens & camera?

OK maybe it is the sun - and perhaps my theory on exceeding the aperture limits is correct. I'll try some controlled experiments ... but I wonder is this a feature? I believe light sensors can get "burned" by exposure to exessive amounts of light. Is it possible that if the camera detects the sensor might be exposed to excessive light it locks up?

But I agree that the D60 is no comparison to the EOS3/EOS1 family - I suspect that the 1Ds is the camera we REALLY want - but not at UK 7000!

Cheers,

Colin
