This might just be me missing the point, but Photoshop 3.2? How old would that be...

Taking that at face value, you won't open RAW files without a RAW converter, and that wasn't in PS until CS arrived.

The point is that they aren't different manufactrers - the Schneider lenses are made by Pentax in the Pentax factory. The different cosmetic arrangement is purely that.

It is identical in all respects apart from the outer livery. The coating looks exactly the same, but isn't labelled SMC of course.

Proper macro lenses don't have a "macro mode", which is more the stuff of zoom lenses. What they do is to have an extended focusing range that, without interruption, goes down to 1:1 magnification. That is, a 1cm long object is 1cm long on the film/CCD. Obviously when the enlarged image is printed there is huge magnification with much better critical quality than using close up lenses.

I concur with George that the 100mm macro lenses are much more versatile. Pentax make an excellent one, but equally well there are second hand macro lenses on eBay for more realistic prices.

Don't discount manual focus macro lenses either as at very close distances AF is not very useful for many subjects. AF lenses can be used to focus manually when required, by the way.

I use the SMC Pentax-FA 100mm f2.8. Superb lens.

Pressing the RAW button records the image in both RAW and JPEG formats, and will take up more space accordingly.

As to formatting the card John, are you referring to the 6mp vs. 10mp ram question?
No, just the number of shots available, which will reduce if the card is not fomatted before first use and thereafter every time you want to delete all the images and start again. Deleting the images is noit enough.

Oh, and the reason I considered shooting 6mp RAM for this project was that all the pictures had to be taken about one second apart (hence as many high res pics in a row as possible).
JPEG would be ideal for this - 3fps till the card is full, ay 10MP, no problem with quality either.

I got twice as many photos from the card as should have been possible. That's my question. The display said 414 pics, I ended up with 900.
The only possibilty I can think of is that you changed the resolution, then shot till the card was full without the camera being switched off and on again, so it never re-read and reassesed the number of images. Just a computer thing. Unless someone else has a better idea?

Did you format the card when you were ready to delete all the images and start again? If not, the old directory structure may well take up space and reduce your number of images.

You might as well shoot at 10MP and have the best quality available to you. If you shoot RAW then surely that is the output from the CCD, almost unmodified, and that will be the same regardless. If the camera lets you set 6MP then it can only be interpolating the size downwards, Don't see the point of that.

If you are using JPEG I would expect the number of images to change depending on the resolution set. Although I don't see the point of using a 10MP camera and setting it to 6MP. Might as well use a K100D and have lower noise levels.

Just right click on the image, go to properties and highlight the URL. Then click Ctrl+C on the keyboard and the location will be copied.
