You have a K10D and two fine Pentax lenses, so you already know the answer....

Not a lot of difference in that macro lenses are almost always used at small apertures anyway as DOF is so limited up close.

The f4 aperture of the Pentax means the construction can be simpler (better contrast), the corrections are simpler (better performance) and the size of the lens is more compact.

The one I tried certainly wasn't, so there must be more than one model with the same spec. The one I tried was a monster of a lens!

Why not look for one of the Pentax manual focus macro lenses. Good though the Vivitar and Tamron ones may be, the Pentax ones will be better and more compact as well.

I'd try it anyway, only because your direct photograph might be better quality than the scan. or vice-versa, but at least you would know for sure.

There's no substitute for giving things a try!

No filter, it's the bright light sources causing the effect.

You can get entry to the Library no problem, but special permission will need to be sought for any photography.

This was a special visit by our camera club. We also got to view a slection of archive items, including Fox Talbot's "Pencil of Nature"

Thanks, Steve, good to hear from you.

Have a great 2008!

One way is to mount the camera on the tripod but leave the movement loose, so the lens is supported but not held firm. It improves stability without sacrificing the ability to track the subject.

Well one thing it won't do is slow down the movement of the wildlife, so a high shutter speed may well still be necessary.

Just to remind everyone that the rules, such as they are, do specify one image per person for each competition. On the one occasion that someone inadvertently posted a selection of images they chose the one they wanted to keep and withdrew the rest.

Don't worry, it won't develop into a competition of panels of images!
