It's a bit vague becasue we don't know what style you may be after, or indeed what the location will be.

For informal pictures of an author aome shots in a study or library might be good, but there are so many alternative possibilities.

Rather than ask which lens I would be thinking first of which style and which location. The choice of lens will probably follow logically on from that.

Lighting levels will be variable in a stage show, but are generally quite good. Using an appropriate ISO you should be OK with a f2.8 lens.

However, at the longer end camera shake may start to be an issue so the range of the 50-135mm may not be so fully useable as to be a useful advantage.

Personally I would tend towards the 55mm f1.4 (or indeed FA 50mm f1.4) and crop as required.

I really like the moody feel to the horse shot.

The texture in the second one also appeals - very nice indeed.

Not yet, still some time to run.

I'm sure I didn't! Nice thought though.

I can confirm that the post was never made. It might have failed before it was entered into the site database.

Very occasionally I write a post, get distracted and forget to press Add Comment. Is this a possibility?

I will check now to see if has been deleted.

To be fair, that is not what the Fuji sensor is about. Each of 6 million photosites has two pixels, one to read low light and one to read high light levels. This makes your 12MP. The advantage is said to be extended dynamic range.

The other odd sensor around is the Fovean used by Sigma - this could be considered to have one third of the 14MP it claims to have, depending how you look at things. In this case the three colour layers are stacked on top of each other, rather like the way a colour film is constructed.

One of the most commonly found models, so no fortune to be had I'm afraid!
