As most would know i recently gave my sensor my first ever wet clean, and although happy that all spots had gone, I got the impression all my images looked softer than they should.
Looking at my sensor there was no apparent haze or residue from the clean so I decided to do a test on my top lcd of my camera.
First I did as said here following all steps from 1 to 6 and noticed that on this glass I could see a minor misty residue was left behind after the second wipe.
Then I did the same again although only steps from 1 to 3, and then change the pec pad and then repeat the steps on the opposite side of the sensor. No residue to bee seen this time.
I also found (like many others have said) that 1 drop seems to have a better effect.

Here is a fence pailing at actual pixles after the first clean following all steps

And here is the same image shot after the second replacing the pec pad before doing the opposite side.


I'm still not overly happy as I believe that my results are still softer than they were before my wet clean. But until I can find a cloth that leaves less residue behind than the Pec Pad's, I am just going to have to deal with it.

How much fluid have you been using on the pec pads ?

First couple was 2 when it was really bad. Probably the last 5 or so were just the 1.

Pec pads is the only cloth in this world to clean CCD! and it's safe.
Don't be fooled by trying other type of rags.

So, 320 grit wet and dry is not recommened then?

I was gonna try some 50 grit Give my photos some real texture.

Newidude - please keep us informed. I have got the fluid etc but have been too scared to actually do my sensor for the same concerns about fluids on the sensor.

Soemthing is not right here...what fluid are you using?

G'day,

I've done a couple of wet cleans on my D70, first was a bit nerve racking but OK after that... Since the second one though I got a rocket blower and haven't given the sensor (or the glass over it anyway) a wet clean since... Best thing I've bought I reckon... I can even see through my viewfinder now, looked like a bowl of spaghetti before...

Never had residue before though, using eclipse and a swab... If you can see it with your eye, then something's not right,

I assume you're using eclipse fluid?

There is no way any surface residue could have produced that kind of softness. Well, maybe a smearing with vaseline could have...

To me it looks like you're knocking the sensor in and out of alignment from one cleaning run to the next. (Is this even possible? I haven't disassembled a Nikon DSLR - yet.)

The first of the two images is plain and simple out of focus, across the frame. Did you notice any sensor movement during cleaning? What f-stop were you using? I guess with anything slower than f/1.4 the sensor displacement would have to be noticable to produce this much OOF.

Maybe you should have it looked at by a repair pro? Possibly something else is playing up and causing intermittent bad focus?

Cheers
Steffen.

98 PULP or AVGAS or JP4

Birddy, you have found the problem, Brad should be using the new 100 PULP which has just come out.

Are you sure that isn't blur in the first one, Brad? I have never seen a result like that.

Johnnie Walker red label.
