Cleaning

Right just tried to clean my 5D sensor for the first time, it was previously done by Canon under warrenty. Put a spotlight on the workspace etc. off I go...

Used the a blower first
That put 10 times as much muck on the sensor - great!

Artic butterfly next. Brand new. No I didn't touch the sides. Smears all over after first wipe and it didn't lift much muck. Yes I spun it before. Didn't touch the sides but the sensor was smeared after- (not before). Not impressed at all by what is IMO an over priced piece of junk.

So I tried the Sensor swabs, first one with one drop of Eclipse either side. No better.
Tried another swab with 2 drop either side. repeated with two more swabs. Still no better. My sensor is now a complete mess.

I watched all the videos and did exactly as I was told.

My sensor is no 100 times worse than when I started.

So now what - send it to Canon?

If the Arctic Butterfly transferred some grease or oil to the sensor, you'd need a number of swabbings to get rid of it. Are you truly seeing no difference between Eclipse/Sensor Swab passes? And if you use too much Eclipse, you may smear more than clean.

The artic Bfly did obviously put stuff on sensor but I would have expectd it to be clean as it was brand new - the intructions didnt say you have to wash it first

OK so would you recommend that I try again with sensor wipes with just one drop?

Yep. Couple of smooth passes with a single drop on a fresh swab each time, per the directions.

I'll give it another go

Wow, that's a lot of muck! Good luck with the cleaning.

Well tried another couple of swabs , one drop of eclipse on each (one at a time obviously) gave each as smootha wipe as possible - still dreadful

Am I supposed to be pressing harder? I am reasonably gentle but firm enough to be sure I have contact

I use the eclipse method, and it has never failed me. Yes, I have failed me, but I just cleaned it again. I can't say how hard to press on the sensor, because it could be a completly different feel for you than me.
As stated, always use a clean pad, and two drops of the fluid. One on each corner.

If your section of the little blue planet were close to my section of the little blue planet, I would be happy to show you.

Hi thanks for your kind offer, I'll be over in the morning!

OK I think I'll try yet again today, I do wish the butterfly thing hadn't made it worse at the start!

One or two drops...???


OK I have given it 5 more wipes ( one sensor swipe each time) since last time and looks like I am getting there

However I can't get into the corners it seems and there's that funny blur in the middle

even with one drop only in each corner of the swipe pad it still leaves a visible film over the sensor when viewed in direct sunlight - is it supposed to do that?

please tell me what you think from the shot below?

Using Copperhill, I have had better luck using less fluid, rather than more.

Looks like one more swipe & you'll have it. Nice work

yup less is better -definitely - it looks like the first swipe and the first time I used the Eclipse that more than one drop each side got on, and the reason for this is that unless you are very careful without warning the ECLIPSE bottle dribbles instead of delivering single drops as soon as you incline a full bottle. So you get several drops in rapid sucession (and in my case without realising it)..

A better warning about this tendency of the bottle to pour rather than give drop doses wouldnt go amiss.

Thus holding the bottle probably too close to the swab, it had dispensed several drops whilst I thought I had only put one on

I didnt realise this was happening until about the third attempt

You have to tip the full bottle VERY carefully and against a dark background so you can see really clearly that only one drop is going on the pad

The first time I ever used a wet method to clean the sensor in my 1D2N a couple of weeks ago using the Copperhill kit took many, many swipes. The dirt that was in there built up over the last two years in all kinds of conditions so I wasn't too surprised.

Of course, now I have all kinds of sh*t floating around above the focusing screen.

Keep swiping, you'll get it!

Thanks for the encouragement - how do you get the corners without touching the edges?

I went right up against the plastic ridge surrounding the sensor/glass. Having the PecPad almost dry ensures no Eclipse seeping under the glass. No worries there, just go right into the corners. A full sweep along one side, flip, sweep against the other side.

I went through about ten PecPads, I would imagine. I was getting quite frustrated cleaning, taking a picture, cleaning, taking a picture... But each time it got a little better - as was my technique. In the end it was 100%!
