One way that does work well is to shoot JPEG and switch on the CA removal option. It does reduce it very dramatically, provided that it's a Pentax lens that the camera will recognise.

The downside is that the extra processing takes time.

No, that's not what I'm trying to say, so I'll explain more fully.

Over the years, it has to be said that I've bought many makes of both cameras and lenses. I have concluded that I would have saved a fortune if I had paid a little more and stuck with marque lenses and accessories right from the start. Buy cheap, buy twice as it's said. That would equally apply whether I had settled on Nikon, Pentax or anything else.

These days I sell a lot of classic and modern camera kit and have the opportunity to examine closely a wide range. Sometimes I have the chance to test them and then I look even more closely.

I'm not a Pentax fan, so let's dispense with that notion, but on here it's called Pentax User so that's what we talk about. The reason I settled on Pentax is that I enjoy quality engineering and I like the ergonomics as especially the digital colour.

Third party accessories rarely fit as well and rarely have the same quality of finish as marque ones do. Third party lenses may sometimes be excellent, especially these days, but that was not always so. Anyway, the quality isn't all of the issue. Matching colour balance and operational systems is more of the issue. In the manual focus days this might mean all the focusing rings and aperture rings turning the same way, not some clockwise and some anti-clockwise.

Anyway, even take a simple thing like the optical viewfinder for the Q (or GR for that matter). some quail at the price, but these simple items are in themselves beautifully made and of superb quality. Do we want Leica quality or Zenit quality? I know which I enjoy.

Take a Pentax lens, most of which have stainless steel mounts secured by five screws. Many third party lenses have only three screws securing them. I expect the Pentax one will break apart very rarely.

That's the reasoning, and a few examples, but it's definitely not narrow sighted. I keep looking.

What makes the difference is how companies design their products, put them together, the standards they choose to apply and so on. A sensor is not just a sensor, there's a whole lot of processing that goes with it. Then there's quality of components, quality of assembly and testing, and of course ergonomic design.

This is why I don't feel tempted by other marques, and there's no shortage of options, this is why I stick with Pentax. The quality level is right, the design is right, the lenses are superb, the "Pentax colour" I've often referred to is exactly what I like.

Cameras are functional items as well as, sometimes, objects of beauty and it's very important to me that the kit I use matches ergonomically and in terms of performance. So no third party lenses and accessories and definitely no mixing of systems.

I don't think you can judge the quality of the K-3 by somebody else's experience with a Nikon....and the K-3 is also a very different beast to the K30.

Well I wouldn't say it's very negative because its message is clear, but it isn't particularly inspiring either. A mixed message.

Progress happens all the time and so it should. There's nothing wrong with buying a different Pentax body - the K-3 will not be the automatic choice for everyone.

This is not corporate cynicism, whatever that is, it's offering a good wide range of options for the market as a whole.

Surely choice is a good thing?

I'll be there with Sue and 40 others from ADAPS. We hire a coach and enjoy a good meal on the way home as well.

A few of us will be in costume, so you might see Sue and Granddaughter Beth swooshing about Whitby. I'll be the one with the Pentax K-5 and the Billingham Hadley pro bag.

Wales used to extend well into Cumbria - have a look at place names and there are lots of clues there.

The British Isles (if that's what it is these days, United Kingdom if you prefer) has seen many Kingdoms within it in the long course of history.

That's a shame really, the new HD limited lenses are getting superb reviews and three of them are already tested on PU. See the pane on the right.

The 35mm Macro seems to be a stellar performer and the 70mm is not far behind. I did love that 70mm when I had it, I really must try and get one. Too many goodies to spend on I'm afraid.

SD cards are not permanent and if stored for long periods of time the data on them can become unreadable. They may not be ideal for long term backup.
