Slightly off tack but just posted above a problem I'm having with mine. On my K-r , AF is fine for reasonably close objects (say up to about 25-30m) but after that it is very hit or miss, making a clicking noise and going back and forth either side. This seems to happen in reasonably good light and most subjects. It's unusable for distant birds in flight, helicopters etc. Do you think there is a fault. DAL 55-300 seems much snappier and to be honest I was expecting the opposite.

Forgot to say Liveview takes forever to autofocus, dont bother with it, thats unless you get your flask out while you wait.

Lot better on the K-r than it was on my K-x but I must admit I rarely use it, especially as I have to put my reading glasses on - no dioptre adjustment there!

Yes I know the problem, it's a pity there isnt a sort of magnifier glass you could put over the screen to protect it and make it easier to read.Lot better on the K-r than it was on my K-x but I must admit I rarely use it, especially as I have to put my reading glasses on - no dioptre adjustment there!
I think I will invent one tommorrow, could make a fortune!

Agreed! You can get those clear sheets for putting over news print to magnify it for reading. WOnder if a piece of that would work. Probably not optically pure enough. My old dad used to use one - now I'm old!
