Unfortunately it can't be fixed in time, so apologies to all, hopefully next time will be fine.

Your second thought is spot on.

2x Macro Converters have additional focusing ability built into the TC. I'm not sure if this means that they could focus to 1:1 as a result, but I have a feeling that might have been the reason for their existence.
Proper macro lenses used to focus to 1:2 only, modern ones tend to focus all the way to 1:1
The macro lens is the best option in terms of quality. Its only disadvantages are cost and bulk.

Because the closest focusing point does not change. A 100mm lens focusing to the minimum distance of a 50mm has approximately 1:2 magnification, which is the same as many macro lenses of the manual focus era at least.

If you must use a TC then a 50mm lens will at least give you the best of things. Quality will suffer, but on the other hand it will effectively create a 100mm f2.8 Macro Lens which could be very useful.

The pity is when a buyer is less aware and can't tell that a lens is sub standard. Then they could well blame themselves for poor results when in fact they have never had a decent chance.

Perhaps they don't want people testing the lens on brick walls because they won't look very straight any more. Then people who never take pictures of brick walls will complain because the lens isn't good for taking pictures of brick walls.

Prieni, you won't see a picture anywhere that you've filtered out. Anyone can look at your portfolio.

The K10D uses a LiIon battery pack, but this does mean more shots per charge. Otherwise, the differences are small and may well not be significant to you.
I would happily use either.
