Can't make it this time, but we'll be there in November.

The answer to that is probably spam posts. By the time you go to look at them they will have been removed.

There are hoiods for the lenses, but only the 01 prime comes with one included, a design very similar to the DA 40mm f/2.8 Limited. The telephotos need a bayonet hood and I use one . Always using a hood is an excellent idea, even with the best coatings.

I like the output from the MX-1 and Q-S1 cameras. The latter, coupled with the 15-45mm lens is very nice for flowers:

Your maths Derek will reveal the magnification at the distance you focused on, so if you want the maximum magnification, you go for the closest possible focus.

Maybe there was a malfunction because the connection between camera and lens was lost? You mention that removing and reseating the lens cleared it.

The lens and mount contacts could perhaps do with a with with a clean, dry, lint-free cloth.

I have used the Tamron and Pentax lenses side by side and the Tamron is very good, but the Pentax is crisper.

It would be easier straight on. You know the size of the sensor, you can read off the size of the ruler, so you can work out the magnification ratio.

If you take an image of a ruler you should be able to work it out.

The Pentax is a brilliant lens. I find it very useful for flower portraits; it pulls in the flowers so really nice close ups are possible. It's very useful for wildlife and also very usable with the 1.4x converter.
