(showing my ignorance) .... Is this for viewing prior to taking a picture in live view or simply post viewing of the result?

Hmm. Rip the rubber off an old M42 hood and stick the plastic bit that's left to a loo roll core. Screw that into the mount adapter. Make a pin hole affair, as described on a tube that fits the loo roll. Use masking tape around the loo roll to make up any diameter differences and ensure light-tightness. Voila a zoom pin hole :

The answer to this one ought to have emerged anyway in that the camera must recognise the lens for which you want to store correction values. Older manual lenses have no inbuilt identity and so couldn't be affected anyway ........... or is that me lifting my left leg in the air?

These links are for a pair of sites that I found highly useful when learning, especially the second one, the author of which used to be a member here I believe. There are a fair few Pentaxians on the first site too.

The Pentax f4 100mm macro lens comes up on Ebay fairly often and is well worth acquiring.

Gives a new twist to the term "legging it" !

That is indeed a fantastic site which got me started down the macro road - including his instructions for taking the glass out of an 'A' series 50mm lens

Excellent shots. You caught the plumage perfectly

I used pixel shift to shoot the underside of a leafy canopy last autumn. The results were tack sharp except that one or two of the branches were duplicated, side by side. The wind had moved them ever so very slightly during the exposure.

Try scraping the anodised black paint off where the tube touches the camera contacts. I tried a normal set and got the same problem you describe and then I tried a scraped Vivitar 2x converter tube (with the glass removed) when it all worked properly. Also, it helps to have the camera set to 'M'.

Paint or play?
