Questions like this are best answered via a PM or a report, so they come to the attention of the right person who can give you an answer.

New items are put in by the team. Replies can be made by anyone, but I've removed all those rather odd ones for this item.

It's the same. There has been some debate as to whether coatings were different, but I doubt that there was any difference there either as the reflection colours looked exactly the same.

What is different is the livery and cosmetic design.

Without "early adopters" progress might be much slower. Generally, I'm sure that manufacturers try very hard to iron out any problems before release. Such is life though that at some point things have to get on the road and go live, so that's usually a fast and furious moment. There will be things that slip by, but the wider experience once in the hands of buyers will soon reveal any shortcoming. Then it has to be addressed of course, hopefully by a simple firmware upgrade, but maybe in bad cases by a partial or even full recall.

I don't see any way round it?

The *istDS should retain its settings for a while after the batteries are removed. There should be ample time to change batteries. If there isn't, perhaps a fault has developed.

I'll have to think about that one! Just now it's too late and the theory was learned too long ago, so I'll go back and revise......

Common sense tells me that if we have 1:1 with 35mm format and we change the sensor behind the lens we crop the image. Therefore, the magnification increases.

Still no report though, so nothing can be done until the information is provided. PM me the username of the miscreant and it can be actioned. Or file a report.
