The end of Sepetmber will see the end of the actual photography for the Images of England project. This was an English Heritage project to record all 370,000 listed buildings as they were at the millennium.

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.

The IOE site can be found at www.imagesofengland.org.uk

Thanks Liam, I'll check those out.

I'm looking for an unwanted digital camera (1.3MP would do fine) so that I can teach my 5 year old Grandaughter how to take pictures. She's had a go under supervision and did pretty well.

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!

In terms of resolution, slides will beat digital images every time. However, if you project slides against a digital projector, the digital images appear to be brighter, sharper, punchier in every respect. And that's at the relatively low resolution of 1024 x 768.

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.

Camera lenses have not been marked in T stops for a very, very long time. 50 years, 60 years?......

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.
Don't forget the marked focal lengths of all lenses are nominal. Most 24mm lenses from the MF era were closer to 25mm, so Zeiss could simply be making a slightly more accurate (or honest) statement.

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.

Generally if you right click the image and go to Properties you will find the URL. Copy this and then paste it between the Img tags in the forum message box.

Enlarging lenses are computed for short distances, so are ideal for macro photography. You need exactly the same things that you needed for your Spotmatic, with the addition of the Pentax Adapter K so you can fit everything on the bayonet mount.

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.

I think you've answered your own question.

Back to the shop is my vote.
