If you want a diddy little simple flash for the top of your K3ii the (ancient) Helios Compact Flash is about identical to the pop-up, uses 1 x AA battery and has a low trigger voltage. I also use them in multiple with Nissin Synchro-eyes. No fiddling. They go FLASH! with no frills. Commonly available on Ebay for .99p - £2 ish.

I tipped a bottle of beer all over my keyboard and it too behaves quite oddly at times!

Certainly, the British ones will jump onto your hand if you offer it. They just can't resist it.

I was fortunate to capture a little 'lake' of rainwater today as it overbalanced from a nasturtium leaf.
We think of water having a perfectly smooth surface, or in this case, meniscus, but you can see stress lines forming across the surface
as it gets ready to spill.



Water, in tiny quantities like this, and on highly repellant surfaces, behaves more like a mobile solid. It even has a well defined 'underside'.



And in a split second it overbalances and moves so quickly there isn't even time for a second shot.

Yes indeed. That's exceptionally clever !

Most of your subjects will try to leg it. You need stuff that stays still

Combine ZP is excellent, especially as it is free. It has but one quirk and that is, it sometimes leaves a (very narrow) border of incomplete processing around the edges, so be sure to allow a tiny bit of leeway around the part of the image that matters. Then you can simply crop it off the final result. I tend to use my bellows and then it is easy to accurately advance the focus by the millimeter increments on the carriage. I generally focus on the furthest extremity of the subject, note the position of some convenient index marker on the scale, then focus on the nearest part of the subject. This gives me the extent of the carriage travel needed to photograph the whole thing, from which you can determine how many incremental exposures will be needed. (e.g. count the millimeters). The lens itself is set at infinity throughout. The carriage movement does the work.

Like Roger says, Go on - have a go!

As said aabove, the second one is super.

I rotate Pentax originals, Maximafoto and Energisers quite indiscriminately in my K3 and K5. I don't even bother looking which is which. Some are years old and give no trouble at all. As a result, the "charging stress" on any one of them is much lower than it would be on a single battery.

Someone asked a perfectly respectable and intelligent question of a supposedly 'friendly' forum. The basis of that question has been verified and past experiences indicate caution so why this sudden agitation when she quite reasonably refuses to risk 'bricking' an expensive camera?
