Canon G9 problem
      #667625 - 17/06/2008 12:32

Hello
This is just a quick query really. Has anyone in the forum with a G9 suffered vertical scratches on the lens element that they think may have been caused by the lens 'doors'? If so please let me know as I think this may be a problem that Canon need to address.

Thanks
Richard

Is it safe?

Hi Richard,
I think this should really be posted in the Canon forum.

However, I do own a Canon G9 myself, which probably gets much more use than most, but it has not suffered any such problems.

Nevertheless, the 'doors' that cover the front lens element are somewhat flexible, and certainly not as substantial as a regular lens cap, so don't rely too much on this mechanism to protect your lens.

Could the scratches have occurred when the camera was in use by banging against anything, when the lens doors were retracted?

It is a problem which has been talked about on one of the Flickr G9 group discussion boards, same as the G7. I don't remember anyone following up with Canon's reply though. Best to talk to Canon see what they say, and let us all know how you get on.
My G9 has a scratch of the front element, I know exactly how it got there and it was my fault. I did look into having the lens module replaced, but decided that as it's only a problem shooting directly into the light, I could live with it. This is one of the many shots, post scratch.

Gorgeous photo. I'm no expert but that owl looks absolutely wonderful. Going slightly off topic but how did you take it? Auto, Manual?

Thanks Bokkie, it was taken at a Nunhead Cemetery open day and I was mostly shooting B&W film that day, the G9 was with me 'just in case' as such this is me being lazy.

RAW
ASA set as low as possible 200ASA it was overcast / raining all day.
Focus would have been centre point AF, I would have focused on the face and reframed for shot.
Exposure was would have been P which is how it is most of the time (though I do use the exposure lock * button quite often)
EXIF shows exposure was 1/25th sec. at F4.8
So the Canon did most of the work, I do like my G9!

I like mine too. I don't have the 'eye' to see a photo shot like yours but maybe I don't use my G9 enough to improve it. I also use P-mode exclusively now and I've sort of learned to change the ISO dial to match the ambient conditions. You've given me some good information about how you use your G9 and that sort of ties in with how I've set mine.

If I understand you correctly you focussed on the owl's fizzog and pressed the * button to 'lock' the exposure for that point and then reframed its bonce and then took the photo? If that's so, does the * button work only for the shot you are taking or do you have to press it again to cancel its effect? Maybe I need to start a new post on this subject?

I love the * button. Cancelling I find difficult. I tend to switch off the camera to get rid of it.

You mean the "professional" mode!

Probably quicker to take a picture which would clear the exposure lock, (BTW works with pre flash as well- caught me by suprise that one) than it is to turn off and back on again.

As for P-mode, there are times when a wider aperture or faster shutter speed is required so Av or Tv modes are used. M hardly ever gets used, unless a look at the histogram or LCD shows the exposure to be way off what I wanted, but that's not often.

Thanks for the feedback. I have no idea how the scratch happened - it just appeared one day. Those doors are very close to the lens and a bit of grit must have got in there somehow. Like you I find it is only a problem shooting into the light or if the sun shines onto the lens - I also found that it is possible to almost get rid of the ghosting in Photoshop with a bit experimenting with lassoing and use of curves or brightness/contrast sliders.
There's a pic of the scratch here: [image]http://www.blipfoto.com/view.php?id=154694&month=6&year=2008[/image]
