Many AF lenses will continue to rotate indefinitely, so I wouldn't worry about that unless you have a focusing problem.

As for the first point, the lens is stopping down and then releasing again and maybe the mechanism that controls this is making the noise. If the shutter was tripping a frame would be used and you'd know it from your file number.

I'm on the page that the K-5 is still a superb and relevant camera. If the camera continues to deliver excellent images and you are happy with it then I would say keep the K-5. This is not an attempt to dismiss the K-3 but there is no point to change for change's sake.

Whether the K-3 represents a sea change from the K-5 remains to be seen
I am beginning to wonder whether sea changes from the K-5 (or K-30) are available anywhere now or ever will be. The term "diminishing returns" springs to mind.

I'm beginning to wonder the same thing. the only images that have excited me in terms of IQ recently are those from the latest crop of Full Frame sensors.
The problem lies in deciphering whether it's the images themselves that are exciting, and that has little to do with what was used to capture them. Always, a truly inspiring image will banish any thoughts of what was used. It really doesn't matter in that context.

There are also cameras that excite us and inspire us to go out and shoot images with them. Something new can elicit this response, but it's a good thing because it rekindles interest.

We have a local computer shop and we would go there and get a computer made or modified to our specification. It is so much better IMHO that relying on pre-packaged PCs from Currys/PC World, which are invariably tweaked towards gaming.

Perhaps sales people being constantly pushed to sell "add ons" when selling a camera could also be a factor? The profit for retailers could lie in the filter, case, maintenance kit and insurance that they want to add on to every sale.

Just thinking back to around 1978 ... two of us were doing a series covering casting from making the wooden patterns, sand moulds, casting, fettling and basic machining. In that environment there can be some real nasties flying around and changing films meant leaving the building to stop dust entering the body and lenses were never changed.

At the end of it, my filter was ruined and the other photographer had a damaged front element. In both cases particles had welded themselves on.
Maybe so, but that simply comes under circumstances where a filter might have to sacrificed. Common sense to use one. The salt water spray example offered is similar. In adverse conditions, we protect camera and lens, but not all the time.

The 5 and the 5ii have the same sensor and the AA filter so the image will look the same.
Very similar, but we don't know what other tweaks were made, so the K-5 II may have slight advantages in this respect, or maybe not.

I have used both and the IIs is crisper, as we would expect. I saw this straight away when I did the IIs review. The same characteristic is seen in the GR, which also has no AA filter.

Save your money, unless you are so clumsy that you stick your fingers all over the front element. In which case it would happen even more to a filter.

Filters that are useful are ND grads, polarisers and UV/Skylight if there's going to be a lot of salt spray hitting the lens. Apart from that, save your money and always use the hood.

Well you clearly spent a lot of time on that post, but I really do think we need to move on now. The opinions of those concerned have been very clear for some time....
