PENTAX Image sensor cleaning kit O-ICK1
A bit of research indicates that Eclipse E2 fluid should be used with Tin Oxide coated sensors. Now all we need to know is if Pentax use TI sensors. Also, Wex and BH both suggest using sensor swabs rather than Pec Pads. There are also warnings about picking up muck from around the sensor if us...

Thanks for that so far, John. I haven't got the E2 fluid, just ordinary, whatever that is. I tried their website, www.photosol.com but can't connect to it...if it still exists!

PENTAX Image sensor cleaning kit O-ICK1
I've corrected your link, which now works. Unfortunately it doesn't mention E2 fluid, but it does say the following: PEC*PADs are not recommended for cleaning the CCD. PEC*PADs are not made from the same materials that are used in SENSOR SWABS. SENSOR SWABS are manufactured and sealed in a clean a...

PENTAX Image sensor cleaning kit O-ICK1
I don't think there is much of a risk in using Pec Pads on a sensor. They are non-abrasive and will not damage it. There is a risk using anything that applies an amount of pressure to the sensor if there is dust on there that could scratch it. The companies that make these types of cleaning produ...

PENTAX Image sensor cleaning kit O-ICK1
Nonetheless David, it's surely prudent to use the right products for such a critical part? Is there a point in ignoring the advice of the manufacturer and not using the product they make for the job? But the bit I was really concerned about was the solution stripping the sensor coatings. In the c...

[quote:3496ace15f="johnriley"]Is there a point in ignoring the advice of the manufacturer and not using the product they make for the job?[quote] No, not per se John, but then again the manufacturer will always recommend their own kit, or possibly kit they have a financial interest in. I'm not s...

PENTAX Image sensor cleaning kit O-ICK1
I'm not suggesting this falls into that category Definitely not in this case - Pec Pads and Sensor Swabs are from the same manufacturer. Pec Pads are for lenses, Sensor Swabs for sensors, and they do tell us why. What you say about alternative products can be true, but of course also often isn't ...

PENTAX Image sensor cleaning kit O-ICK1
Are there not two types of Eclipse fluid, one of which should not be used on Pentax? I looked into this last year when I first bought Eclipse fluid since I had no idea whether Pentax sensors had a tin-oxide coating or not (still don't). I found out eventually that E2 wasn't made any longer because ...

The link still didn't work for me, John, even after you had corrected it. But, it seems, no matter. All's well that ends well. Thanks John and CMW!!

K-5IIs - more discussion
Hasn't this all been excessively discussed in lots if detail in other threads already? Comparing sharpness of mkiis to mki proves nothing as they are not the same in terms of improved focus and removal of the aa filter and slightly improved sensor and firmware. I found the mkii sharper than th...

John - "I think persistently what you are not seeing is the improvement of clarity in detail. That's clearly visible to me and to others as well. I see it in the images." This might be true for original full-size images although, even then, it seems to me that any differences are being greatly ex...

It sometimes seems to me that my contributions to this forum are just as invisible as the differences between the comparison images posted here. I'll try again by quoting from the dpreview page that I linked to in my last post: "In theory, a sensor without an AA filter, when coupled with a 'perfe...

"... vertical and horizontal detail is accurately described (by the original K-5) up to around 2800LPH, with some line detail surviving up to, and even slightly beyond Nyquist." If they think you can go beyond the Nyquist limit of a sampling system then they don't know what they are talking abou...

Aperture has changed all of a sudden
About three months ago I noticed one morning when I turned the camera on and went into AV that my apertures had changed slightly on my 150 500. Originally it used to be: 6.3, 7.1 8, 9 10 Now its: 6.3, 6.7 8, 9.5 Any ideas what it might be? I have used the lens every single day (with the ...

Rumoured announcement of several new DSLRs
petrochemist wrote: If the roumered price limit of $2000 is right then the 645D replacement is out of the question. But if we assume Pentax have made some money out of the 645D, and that with the price drop a little while ago (to approx £6k) they are still making money, then what would a new mo...

Rumoured announcement of several new DSLRs
Hmmmmm. Interesting. Probable? not likely Possible? Maybe. They to serious increase capacity at the factories to cope. This may already be there, we don't know. Now what could take place if true. Entry Level DSLR under the K30. Lets call it the K300. 16MP sensor, no sealing. Upper le...

Video Capture - Pentax or ??
The Sensor Shake Reduction feature on Pentax DSLRs really comes into its own though with video - gives a lovely 'floating' feel. General non photographers looking at my 'home videos' all comment that it looks 'professional' - (it most certainly is not !!!) but its a good first impression. The S...

Pentax K5 IIS - really reliable?
Normally they are very reliable and have no widely reported issues, sounds like it could be sensor failure which is unlucky in your case...take it back to the dealer and I'm sure it will be sorted asap Simon
