No, FW 1.4 will add in all the previous updates as far as I'm aware.

I've been thinking of an " O " ring in the reducing ring, the thread is deep enough to take one, the thinnest available is 1.5mm and this would prevent the two surfaces from locking together.

Have sourced some at minimal cost, will advise if it works when they arrive.

Hi All,

Thanks for the replies so far,

I'd already tried the WD40 type fluid and the graphite suggestion, The Rubber Matt John is a good tip and will try that, will also look at the Silicone spray suggestion !!

A small problem,

I've been sorting my filters out to cover a multitude of lens diameters and now have all filters in 82mm and use a reducing ring to drop to 77mm and 72mm,

One problem I'm having is cos both the reducing rings and filters are slim line, I've had difficulty getting them separated after use, the seem to wish to lock together, foolishly I managed it this morning then in trying to resolve the problem, got them stuck again and its taken 20 mins to bl.........ming split them again

Any tips or thoughts on not necessarily an easier way to split them, but a way of preventing the problem in the first place ?

Here's another one, about an hour after the earlier upload when the mist had re-appeared.

Ah.... OK, thanks Nigel,

I have just acquired a 14mm f2.8 and will bear that in mind for next time, I did use it at this location but again was at F8.

I received a free filter holder for my Samyung, the filters are huge, and 1/3rd the price of the lens, what have you done if anything ?

Thanks Paul,

Most images I've seen have been in colour at either sunrise or sunset with the light picking up the limestone from the side.

The second set of settings will give you a much darker image dure to the lower iso setting and the much higher shutter speed with the smaller aperture setting.

My advice would be to reset the camera to its default settings using the in camera menu and ensure you've got the latest firmware on board.

Then go from there.

Thanks Nigel, the exif defiantly says F8, I did selectively sharpen the foreground, perhaps its that.

One from yesterday morning, quite a lot of mist, so converted to mono.
