The manufacturers will set their sensor sensitivity so that it closely approximates the ISO value, but we should remember it isn't film. It's a sensor and behaves in a different way.
The main effect of the aperture is on DOF and this will be significantly different at f1.4

It's an attractive range and the WR is a useful feature. If it is better than the 18-250mm then it's absolutely good enough. The 18-250mm is not at all a poor lens.
When are we going to see an in depth review of the 18-35mm WR?
Possibly by your good self?
Kindest regards,
Peter.

It's been documented on this board previously that digital sensors can't see f/1.4 they can only see it as f/1.7 anyway

If not then I'm out of pocket for no reason.

Failing that, use DNG instead of PEF and all should be well. Or shoot JPEG.

The f1.4 version has higher contrast and is faster.
This is all related to what the expectation was as reagrds usage. It was assumed the f1.4 was a low light reportage lens and that the f1.7 was the one people would generally have and generally abuse with optical add ons, close up devices, etc.
Of course if you want a low light reportage lens then the f1.4 is better.

Who knows what the outcome would be, let's hope we never have to find out for ourselves.
