No contest, complete the set of FA Ltd's. The 31mm produces stunning images and they are compatible with 35mm film bodies. The DA 35mm is, as yet, an unknown quantity.do I still go ahead and buy the DA35 when it eventually hits the shops or should I seek out an FA31

I went for one like this. It has an interval timer too.

Welcome to the forum woodworm, but be careful. With a name like that, you'll have Clarky crawling all over you with his macro lens(es).

There are a few camera settings you can change to affect JPG images. On the K10D they are called Image Tone, Saturation, Sharpness, & Contrast. The names may be different on your camera, but I doubt it.
Try setting Image Tone to 'Bright' (the coloured icon), then play around with the other three controls to achieve the effect you are looking for.
For the very rare times I shoot JPG, I have Image Tone = Bright, the other three controls are set to +1.
Mike, please don't post any new topics on this subject, just reply to the remaining two that you have opened.

Welcome.
Do you shoot JPG or RAW? Which lens were you using? What camera settings did you use?
Some images illustrating your problem posted here might help us provide an appropriate solution.

I've just been looking at http://en.wikipedia.org/wiki/Fluorescent_tube
Modern tubes with electronic ballast are flicker-free, but notwithstanding that, the article reminds us of the way these tubes work.
The charged gas is in plasma state and releases photons in the UV part of the spectrum. These photons hit and excite the phosphors than line the glass tube. The phosphors fluoresce with visible light, just like a CRT monitor. The colour of the light depends upon the phosphors used, not the nature of the AC power.
There is no mention in the article of changing colour balance and I really don't see how there would be.
Hope that helps!
If the scene was lit by both tungsten and flourescent lights, I can quite understand that the colour temperature of the light will be constantly changing from almost 100% tungsten (when the flourescent is at 0 volts, or glowing at its dimmest) to a mix between tungsten and flourescent (when the flourescent is at max voltage, or glowing at it's brightest).I've just been looking at http://en.wikipedia.org/wiki/Fluorescent_tube

Problem is, a camera will take the AWB reading at a point in time, then some time later, it'll expose the image when the colour temperature of the lighting may well be different, because the mix of tungsten and flourescent may differ.
I can understand how it might happen, but I've never had much of a problem.
PS: I don't believe 'flicker-free' tubes are flickerfree, but I do believe they flicker much less.

Well done all.
