The Pentax-D FA macro lenses are the ideal choice for Pentax cameras. We use the SMC Pentax-FA 100mm f2.8 Macro, which is capable of superb results, so also the second hand market could be a place to look.

I have used 2300 mAh NiMH batteries since I bought the *istDS maybe 18 months ago. Follow the instructions and there is no problem!

You're making a fair point, Arthur Dent, but I have to say that yes, I have seen Hoya lenses. They were around in the 1970s, moderately good quality and not a lasting phenomenon. It was an economy range.

It's wonderfully vague in a specific sort of way, saying all but saying nothing. I think it means they want to make better profits.

I bought the camera plus 18-55 kit lens, which left me with a surplus 18-55 thast is now on eBay. You could do the same with the 16-45, although I'm intrigued as to why you don't need it. Do you already have one of these superb lenses?

There are lots of strange things about that shot - the bright points of light, some smearing horizintally and an extreme lack of sharpness.

Hot Pixels may well be found in all makes of digital camera. In low light, noise reduction is designed to...reduce noise.

It isn't really a problem in normal use, is it?

Well, the camera isn't really intended for taking pictures when there is no light, so I wouldn't be at all surprised if the poor thing didn't throw up a few unusual results as it desperately tried to understand what it was doing.

Perhaps a few tests in normal situations might be more revealing?

Or perhaps even black cats in coal cellars?

When you take an image the signal of each pixel is greater than the background noise level that you are, for whatever reason, trying to photograph. The difference is the signal-to-noise ratio and it will equally apply to audio equipment where it manifests itself as hiss.

As long as in practical use the noise is not visible that's fine. It's no worse than grain on film, especially when, like myself, some people would use fast, grainy films.
