I'm after something very low cost as it may or may not survive very long and an old 1.3MP would be quite adequate. The sort of thing that wouldn't even be worth eBaying. In fact an older model would be a good idea as it would be bigger and easier for her to hold.
Does anybody have anything likely - if so, please PM me with a price and we'll see what we can do.
Thanks!

Of course it's an illusion to some degree, but a very effective one and we had to abandon any ideas of showing slides and digital projection side by side. The slides looked awful.
So I wouldn't worry about it - if you want to project digitally just get the best quality projector that you can. It'll look great.

It was relevant when uncoated lenses could lose 35% of the light even with only four elements. Then coating was discovered when it was found that lenses that discoloured with age ("bloomed" gave better shadow detail than new lenses. This was the birth of knowledge about coating lenses.
Then came zoom lenses and with many elements single coating was barely adequate.
Hence multicoating, and the need now for T stops is long gone.

The Zeiss 25mm is very interesting as this is a key focal length not deemed important by pentax.
You might come across two versions of a lens (not Pentax) one labelled 19mm f3.8 and the other labelled 20mm f4. In the case I am thinking of the lenses are the same.

However the lens on its own will give a fixed magnification, so the norm is to put it on the front of a bellows unit.
With a good enlarging lens (Nikkor, Neonon, Rokkor, Schneider, etc.) results should be outstanding.

Back to the shop is my vote.

It's been a long haul but great fun to be a part of. Here's one of my favourite shots - the Train Shed at Piccadilly Station, Manchester.
