Yes as long as there is no movement over the total time of 4x the exposure speed; if the setting is 1/100 sec then the total exposure will be 1/25 sec. I don't know how effective the movement compensation is, or whether that has some adverse effect.

Just tried the image in Utility 5, I don't know if my computer was having a moment but it was incredibly slow to show the edit changes; the image in Utility 5 kept clicking from a clean edge to one that looked like a double exposure. Saving to a jpeg took about ten minutes but that reintroduced the colour abherration so I couldn't see any advantage over Lightroom. Whilst I had the PSR on motion control setting I guess the moon's motion is the cause of the problem. Thanks for all your comments.

Has the top one got claws?!

Ah, that's a point. These were RAW .dng out the camera and Lightroom treated the PSR image just as normal, but maybe better results with the Pentax software which I haven't used yet.

I don't see mirrorless replacing DSLR as inevitable. Being open-minded I handled a couple at last year's Photography Show, with the idea that one might be handy where bulk and weight is an issue. Distinctly underwhelmed, the eyepiece was like peering up a gnat's backside and in motion the image was juddery. I experienced something similar where for years I used pocket sized Leica binoculars but after getting larger 10x42 binoculars the smaller one feels incredibly limiting. I don't know what the mirrorless medium format bodies are like and I think the market is polarising between iPhones and those with a more professional/enthusiast interest. This is a roundabout way of saying that I don't think the demise of DSLR is as inevitable as some think. And trends are unpredictable - who expected the revival of film?

So there are plenty who are prepared to pay top whack and I would rather see a healthy industry than death by a thousand price cuts.

Thanks, I didn't see the problem until it was on the computer screen next day. I sort of guessed that the time would be fast enough for no movement to be registered but was wrong; I started off with a much lower exposure and shifted speed and aperture until I could see details on the rear screen. F8 should have been optimum but was not so sharp so I stopped down. Mag07, the difference is probably down to me not exactly matching settings in Lightroom.

Last night I took a few photos of the moon with a K-1 and 150-450mm lens at 450mm, and experimented with PSR. Here are a couple of examples at the same exposure of F16, 1/320sec ISO 100 cropped and boosted in Lighroom, first with PSR and the second without, both on a tripod with remote release and autofocus:



Whilst the PSR shot has a bit more detail there is a strange artefact on the periphery in the bottom left and top right quadrants, caused either by the camera shifting slightly on the mount or the motion of the moon in that brief moment of exposure. The same thing happened at different exposures, Any ideas?

I am a bit confused - why are you photographing in the dark?

A quick google finds there are nine species, with two in Australia. Well who would have thought! They look remarkably similar with a rather witless appearance - or should I say stoned? Well captured by the way, are you sure they aren't drugged?

Thanks Don, just curious what these are doing in Oz because they are a rarity here in the UK.
