Perhaps they are referring to what they consider to be the spelling police, or something along those lines. Helpful is debateable....

How will a FF camera improve the standard of your photography over what you can get from a K-5 or K30?
It won't. The only defect of APS-C originally was a lack of wide angles, for obvious reasons. Then the 12-24mm was released and all was well.

I have enough cameras and lenses, I just need a continual supply of subjects.

Unfortunately, once a question is asked things tend to develop, and often become more and more complicated as we go.

We don't seem to have any comments on this forum on this, so can you point us to somewhere on the web where it is being discussed?

The true definition of macro starts at 1:1, although many earlier macro lenses will only focus to 1:2 without further aids.

Modern zoom lenses that are abelled macro rarely go further than 1:4, still usefully close but not macro.

At some point, I think 10:1 if I remember correctly, macro gives way to being called microphotography.

I doubt that the clamp is commonly damaged, there's no warning in the instructions and as the AF is disengaged there's nothing to damage.

I didn't realise it, but there is a Pentax-D FA instruction manual.

This is what it says about the clamp:
Quote:
The clamp switch locks the manual focus position. You can use it when taking close-ups with a copy stand for example.
Quote:
Using the clamp switch:Focus manually, then set the clamp switch to on. The point of focus will be locked. Autofocus will also be disabled. Do not turn the focusing ring tforcibly while setting the clamp switch to on because there is a slight possibility that the point of focus may change.
Hope that helps!

An interesting thought Dave, thanks.

The half-way stage would be the all-in-one Pentax X-5, tremendous value at under £200 and a step up from a compact camera.

After that, it's the DSLRs and the K30 would be an ideal first step. However, you will not have the same macro capability as the X-5 without buying more lenses, nor will you have the ultra-telephoto capability without also buying more lenses.

Check out the X-5 here: http://www.pentax.co.uk/en/Digital%20Bridgecameras/X5.html and the K30 here: http://www.pentax.co.uk/en/Digital%20SLR/k-30.html
