I don't get any over-exposure either, but i routinely dial in -0.3EV compensation with most lenses. With centre weighted metering this works out very exactly for me.

It's a very well observed set of images. I'd be inclined to increase the contrast as they are all a bit grey-and-white, but otherwise spot on.

It is a lovely lens and it maintains its performance through the range very well. Now you really need that K-1 to go with it!

I would suspect something had been pressed inadvertently. Hopefully so anyway.

Maybe digital filters?

Shops may not provide the actual warranty service, but they are the ones you have a contract with and they have the responsibility. The 5 years quoted may be 6 years in the UK, but the onus is on the user to prove there was a manufacturing fault as opposed to failure through fair wear and tear. It's full of practical problems and potential arguments, so a reasonable attitude on both sides helps a lot.

As for warranty, as far as I know SRS are offering 2 years. If you've phoned them and that's what they say, then that's it, no problem.

Some of the YouTube reviews can be really annoying, to me anyway, as they waffle so much. I just wish they'd get down to the nitty-gritty and review the cameras!

Title corrected.

One possibility is that you are set to spot metering. If this isn't used as intended exposures will be all over the place. To be absolutely sure what is happening some sample images would be helpful as it just might be a consequence of the type of subject as well.

Title typo corrected!

I wouldn't spend a fortune on binoculars unless you are really going to specialise, but you're right that the cheapest ones will not be anywhere near as good as the medium priced ones.
