I thought it was interesting that this full frame zoom was still available at SRS. It's actually a pretty good lens, excellent for flower portraits as well as the other obvious uses. Not as sharp as the 55-300mm, but not the same price either.

One per person, yes.

The converter is not matched to one lens, but designed for most Pentax lenses of the era up to the shorter telephotos. I think up to 300mm IIRC.

An extension tune will do the trick. Alternatively, a 2x converter, but that may add some optical compromise. Pentax made a suitable converter, the Rear Converter K T6-2X.

You don't need a mass of lenses.

The last one I shot I used the 18-135mm for most shots, plus the 12-24mm for some wide angle ones and the 10-17mm for some special effects shots in the evening. The 43mm f/1.9 Limited lens also had an airing.

I could have managed with just the 18-135mm if that was all I had. So any standard zoom will be fine.

I really am not that bothered what Sigma do or don't do for Sony. No doubt the FF mirrorless cameras will attract their attention. Things are as they are because of Sigma's commercial decisions, and that is entirely up to them.

The light at gigs can be surprisingly bright, especially at large events. I don't have any difficulty with slower lenses, taking advantage instead of the excellent high ISO performance of current cameras.

I'm sure that f/2.8 would be quite fast enough for anything.

Going back to the Original topic, a DA-L variant of the 150-450 at a discount could be done I think.

The 150-450mm is a big, heavy chunk of glass and that has to be held by strong construction. Especially if we want it to stay in good order for many years of use.

It's very hard in reality to see what could be made cheaper for a DA-L version. We need the lens hood. We need the metal construction and metal mount. We need all that glass. What's to economise on, at this level a lens is either fit for purpose or not.

so how much off the market have sony

Virtually none, because they don't really pursue the DSLR market in the same way as the top three. I've seen these stats as well and it's very encouraging that Pentax's market share has increased significantly. Well done Pentax.

Of course as long as they produce what I want to buy their market share doesn't really affect me as an individual, but it's always good to see someone doing well at what they do well.

Not at the moment, but it has been mentioned and might well happen at some future upgrade point.
