You made those landscapes rock !

One certainly doesn't appreciate how complex the viewfinder assembly is !

I really enjoyed looking at them.

The continentals probably have an excellent point regarding their beer 'purity' laws. The way UK brews are carted about the country, yet still purport to retain their original characters, makes you wonder what sort of muck the brewers are using to adjust the flavours. My daughter is a flavourist and she says you can imitate almost any taste by getting the chemistry right. (She is responsible for a great many of the ice cream tastes we currently enjoy).

Hazyj comments about a Tamron 28-200. I have to agree that this is a stunning lens. It performs way beyond what you might think from looking at it. But curiously, there is a Pentax 28-200 that is just as good - it's the same lens made by Tamron, rebadged!

ooh, these are nice!

Keep on boring me please.

The black and white ones grab your attention far more than the colour ones. I enjoyed these.

"Catch in focus", as described above does a good job but it can fail just as much as relying on the bleep. There is no split screen option for modern Pentax cameras because the designers assume we will all be using their (mega expensive) AF lenses. Many manual lenses suffer from an ailment known as 'focus breathing' where the In Focus indicator will light and the bleep sounds but both remain active when you turn the focus ring a bit more. (sometimes, a lot more). True focus lies somewhere between the start and the finish of this phenomenon. So keep turning the ring and discover the extent of this event from the lamp lighting and to when it goes off. Now you will at least know its extent and you can make an optical judgement in the viewfinder. This is why waiting for the bleep or using catch in focus can fail because it depends on which end of the focus throw you are coming from. If there is a significant stretch of "in focus" it will be wrong at either end but the shutter will fire regardless as soon as it encounters the boundary.
Not a definitive answer/ solution I fear but at least it explains what is going on.

Hear Hear. Old Glass Rules!
