This doesn't work on ME Super's (well it doesn't work on mine anyway) since the exposure comp mechanism actually works by adjusting the ISO fed to the meter.
Manual exposure then. However, the ME Super can be used to take the required images, so a new camera is not necessarily needed.

Are there any techniques that would allow me to use a faster film,
Alternatively, use manual exposure, meter at 1600 ASA and make the under-exposure adjustment manually.
Set your ME-Super to 1600 ISO and try to engage -ve exposure comp, you'll see what I mean.
Of course you can set Manual mode and just underexpose by however many stops, but if you want auto exposure at greater than 1600 you will need a different camera.
George, last I saw the LX was still fetching well over £100, almost regardless of condition. Compare this to my near perfect SFX which recently failed to sell at all for £5, or my Z-50p which fetched £30 including a standard zoom and P&P.

Some of the AF film cameras are going silly cheap, and are good to ISO 5000 DX coded or 6400 manual (note the Z and P series can't be set manually, it's DX coded film or nothing).
The LX is an awesome camera, especially in low light, but they are hard to find in good condition and very expensive.

have to excuse the authors choice of Camera body but hey nobody's perfect

my apologies Golfdiesel, my earlier post was needlessly blunt even if I had been right.
from your sources it looks like it is definitely better to discharge cells in need of reconditioning using a clever charger rather than just running them flat in the device, although I imagine all the cells in a given set will be something close to the same condition if they have always been used as a set (eg the cells in my mouse which never leave it, or the ones in my *ist which I always use as a set of 4).

In normal use you will never, ever, encounter the so called memory effect.
I agree with NiMH's it is generally rare

If you frequently charge any Nickel based cell from a partially charged state, it will eventually suffer from reduced capacity.
If this is the case and the situation has not become too serious, repeatedly totally draining and re-charging the cells can help. The cells which came with my re-chargeable mouse began to suffer from this a few months ago and I was able to save them by running them totally flat and fully charging them 4 or 5 times. Some high end chargers have a "reconditioning" mode which does this automatically, I just left the mouse off charge for a couple of days.
Also worth noting is that these batteries do have a finite lifetime, and the higher rated cells tend to die more quickly. I have a set of 1700mAh batteries which are something on the order of 5 years old and still work great, but these have seen only light use since they were about one year old. My more heavily used set of 2000mAh cells lasted about 4 years before refusing to charge anymore. It may just be time to retire your batteries in favour of new sets.
The Uniross Hybrio cells are very popular at the moment due to their minimal self discharge rate. I have also had very good use out of my 2600mAh cells from 7dayshop (own brand). They are very cheap and have surprisingly low self discharge for a classic NiMH cell.
I wouldn't use R-CRV3s because a lot of them produce 3.7V instead of 3V. It can be very hard to tell which are ok since the packaging frequently fails to mention this vital detail. For this reason Pentax specifically recommend against using R-CRV3s in any of their cameras.

Comment by Mongoose posted on K100D + 18-55mm from Jessops at 17/05/2007 - 20:55


So a 18-55mm zoom covers from a wide angle to normal focal length on digital. A similar lens for film would have to be a 27-137.5mm to give the same angle of view.
I'm not sure if this is still possible since K mount lens prices have gone mad on ebay in the last few weeks, but I got my Tamron 90mm F2.5 Macro with a matched 2x flat field teleconverter for £50 on ebay.
It is a bit basic and has no auto features whatever unless you can get hold of the elusive PKA adaptall 2 mount, but it works well and has taken me some pretty good shots both closeup and long distance as a fairly fast short telephoto prime.
