what a relief hefty1... Happy with the thought that I was not sold a 'dud'...

tomkeet: Have already looked it up... right you are. As it is a 'spare' with lower 'life', it does not matter all that much if it is of lower value.

I have just taken the delivery of a lithium battery, which I will have as a 'spare'. It is a Delkin 7.4V and 1500mAh, whereas the original Pentax D-L150 is also 7.4V but 1620 mAh. Does this difference matter?

Thanks to you all, guys. Will have a look at the DA lenses. Also changing the focus area is a good suggestion, as it is generally the singer or an instrument player who are of interest.
The magnifying eyepiece is also a good tip.
I am at present taking 'start-up' pictures of bands for my new website, which among other things will promote live music in the Portobello Road area. After I have established the section, I would expect the artists to provide me with some pictures to promote their own gigs. So, really, I do not want to spend great amount of money. Other elements of the website are pictures from the Market and surrounding area, so the lenses I already have, should do..
After all the pictures are taken, I will just have to concentrate on updates from the Road.

johnriley: yes, indeed. I will try my 50-200 first.Also will have a look at the suggested lenses.
thanks to all

With my new K20D came 2 lenses, 18-55 and 50-200. I guess a standard bundle. I wish to take some indoor live music pictures, preferably without flash. I understand that ISO should be cranked up to 3200 or more and use a lens that will go down as far as 2.8 or 1.4. Any suggestion where I may find a reasonably good deal?
