Optical overkill?
I reckon you should be more worried about your lenses being up to the resolving power of your K30's sensor, than the other way around. The K30 has excellent IQ, probably a dead heat with the K5ii. And better than the original K5. Logically you might be reaching the wrong conclusion there i.e. if yo...

Optical overkill?
Of course the sensor plays a role. But compared to the glass, it's pretty negligible - certainly if you're using one of the newer bodies from the Kx onwards.

Yes but then you are just looking at the same sensors aren't you? So of course there is no real difference between them. The argument was a...

Optical overkill?
Yes. If we are, as we should be, talking about Pentax equipment, then the answer, of course, is NO, (assuming we are talking about current or recent cameras, all of which have more than sufficient subtlety and resolution to do justice to the best lenses available). You could try to argue that the...

Optical overkill?
The original question, Robin, was from a user of Pentax K-mount cameras. Even if we widen the scope to "tiny sensor" cameras, how many have interchangeable lenses? Not many, so your point is irrelevant. You no doubt post on many different forums, covering a variety of brands, in order to pro...

Cheap sensor swabs
I am wondering if anyone on the forum here has experience with the cheap sensor swabs that are sold on eBay. I know arguments against using them, but I am interested in hearing from those who actually have given them a try and what the real world results were. Did they get the sensor clean? Or, did ...

Cheap sensor swabs
Hi, I have used them on my K10D and K7 to great effect. My K10D was literally dirty with too many spots and what not. I used about 4 swabs on the sensor, gently wiping them, with only one wipe per side of the swab. Now it is absolutely clean. Try not to stop in the middle of the sensor as it t...

Hi jeeess1967 - thanks for the response! Were these the cheap ones from China that you get on eBay? And, we're they the type were the swab is already wet with cleaning solution and individually packed to keep wet? Or were they dry and then you applied solution? Thanks Steve

The cheap ones from ebay are not great, they tend to be fluffy and leave bits of fluff behind on your sensor. You paid hundreds of pounds for your camera so spend the 15 quid or so on decent cleaning stuff to look after it. I bought the ones from SRS to clean the sensor on my K-7 after I made a sc...

You've invested a considerable amount of money in a very fine camera and now you want to wreck it in order to save a few pennies. Beyond bizarre IMHO.

Hi, I don't know which cheap ones you are referring to. The one I bought was something like this (please see link).... http://www.ebay.co.uk/itm/Sensor-Swab-Type-1-Digital-Camera-DSLR-Sensor-Cleaning-Starter-Kit-UK-Stock-/130604340848?pt=UK_Camera_Cleaning_Equipment_Kits&hash=item1e68a01670 ...

I don't feel I want to use something on my sensor that I need to be lucky or not so lucky with - it's too essential in the quality chain. I totally agree with Ken.

Cheap sensor swabs
I've only used the expensive kind as I am very reluctant to experiment on any of my cameras. However, I see these inexpensive ones all the time on eBay and was wondering if anyone here had actually given them a try and what the results were. For example, a particularly inexpensive one: https://...

so everyone here handwashes their cars too? Hardly the same thing and hardly as critical. As for sensors, I have never laid anything on my sensors and have only ever used the camera's own sensor cleaning, plus rarely a carefully used rocket blower.

Cheap sensor swabs
I have cleaned the sensors on my cameras since moving to DSLRs in 2008. I use a decent quality cotton bud with a lint free cloth wrapped securely over the bud. I then apply a small amount of IsoPropyl Alcohol(IPA) on the cloth and wipe the sensor gently. I then leave the camera without the lens for ...

But how do you know that iso-propyl alcohol doesn't damage the sensor coatings?

Cheap sensor swabs
John, IPA is used in the electronics industry as a solvent and cleaner during production. There is every possibility the sensor/circuit board of your camera has been dipped in IPA before being put together in a camera body. Most of the cleaners you would buy commercially for sensor cleaning contain...

I'm sure you're right and I use it to clean my record stylus. A bottle has lasted me over 30 years for that purpose. However, alcohols denature plastics and react in other ways also. What we don't know is what the special coatings are on the sensor, well strictly on the filter in front of the sen...
