I'm not sure this thread should be under this topic.

I heard from someone talking about this 2 things that confuse me.

1. Sensor Cleaning too much may damage the camera and it's advisable to off it?

2. For Canon dslr, only 7D and 5D MKII are able to tell you the shutter counts straight away when you took a picture?

Is there such problem and feature?

1) Never heard of the first point, you have a reference?

I believe when people say sensor cleaning, it mean, manually cleaning the sensor (maybe with chemical or scrubs). Too much manual cleaning is pointless, plus the least contact you have with the sensor the better it is, or you might risk scratching the sensor, etc.

2) For 7D, you cannot tell the shutter counts. There is only a shutter count in the battery info (buried somewhere in your menu) and this count will reset itself once the battery was taken out and recharged.

I turn off the automated sensor cleaning function coz I think it's redundant.
I don't think there's a right or wrong choice here. Personal preference.

Not that difficult to open the last photo with an EXIF reader, in order to see the actual shutter actuations.
This is not a number that needs to be checked with any regularity.
Most important is that the camera still works fine :)

Ya i agree that manually sensor cleaning is not recommended unless you know what to do other then that just use the auto sensor cleaning will do.

camera in working condition is still the main point..:)

according to my manual (i'm a nikon user btw), there's a feature in place to disable the automated sensor cleaning if it is used too many times at one go, and will reactivate again after awhile. as for canon cameras, i haf no idea whether they haf this feature. so why would u worry about automated sensor cleaning damaging ur camera? it will only damage the internal circuitry if u keep doing it continuously without letting it rest. if there's a time span in between each cleaning session, like say u turn it on, then u snap a few pics and turn off again when it performs this automated sensor cleaning each time u turn on and off the camera, there will be no harm to the camera.

as for no.2 i can't ans that coz im not familiar with these 2 cameras. why bother about it? to me i will only care about it when im about to sell it off to others, n this can be checked via a program such as Opanda by checking the latest picture u took

stop worrying about these n go out n shoot more

Then obviously this cannot be the shutter count. What's the point of a counter that gets reset when the battery is removed?

1) Common sense tells us to switch off any device when doing maintenance, unless we are trained to do it otherwise. Everything can be cleaned to death. Use your camera, clean when necessary (hint: dust spots). If unsure how to do (not everyone is into DIY) just visit CSC.
2) Not to my knowledge. Beside this: what's the point of seeing straight away "Oh, that was picture no 34863." It's irrelevant. What you can see is the sequence number of the picture. But this sequence scheme can be changed, it's nothing related to shutter count. If the shutter count is embedded into exif adat you can see it there. Some viewers (Opanda) can display it. If not, CSC can tell you the shutter count. But catchlights mentioned in a different thread about the same question: Most people's shutter count will never come close to the average expected lifetime of a shutter. Most will have sold the camera by then and got the next model.

for 7D, I think the only way is to look at the file running number, but that can be reset.

I'm not worry about this 2 things, just curious to hear about it from someone conversation. To me sensor cleaning is just a bonus but it doesn't help much if there's more dust particle in it.

Actually shutter count is not equivalent to picture/photo numbering. Any time you reset the picture numbering, shutter count will still remain.
For 7D and 5D series cameras, you need to bring your camera to CSC to get an accurate shutter count.

For some cameras in other systems, that number is embedded within EXIF info.

woah, you mean even if I use an exif reader (like Opanda), I still will not be able to read the shutter actuations from a 5D/7D?
darn...

Well, it is stated as shutter count on the menu under the battery information. I believe it is actually not the shutter count of the camera, but more on the life of the battery in which some people would like to keep track of how many shots a battery get before running low.

I would also believe that sometime it is important (for certain people) that they know how stable a battery is. And if they noticed that the number of shots that was being taken before the battery runs low was decreasing, it might mean the lifespan of the battery was coming to an end and a new battery is to be bought.

Nope. You can't use Opanda, EOSinfo or whatsoever to read the shutter actuation for 5D and 7D... can only bring down to CSC for the reading. All the other method, like recording your shutter count per battery charge, or reading the image number (if set to continuous) could only roughly give you an idea of how much shutter count the camera had accumulate.

No bro. Cannot. Only csc can read the info. I cannot understand why canon still refuses to put shutter count to the public till this day.

And that's why you need someone beside you to "guide" you when you didn't get it right...(NOT advocating any of the views, btw)

P/S: oooh I simply love the latest video....:bsmilie:

But wow... I didn't know 7D and 5D don't get no shutter counts...

They do, just that they are not user checkable.
