The second one fascinates me, not the kind of place where you could pull out a camera and take a photo.

I think it's a good strategy, catch them young and make them happy Pentax fans and customers for life.

Here are some tests I did on my M400mm f5.6

My thoughts, if you're into birds anything less than 500mm is a waste of time in the bush, for animals, in the parks they can get close to the car or hide, but mostly they will be a a fair distance away and depending if you want to show the animal only or contextually in it's environment you will still require long lenses.

That's why the Sigma 50-500 is so popular, it's good for a zoom lens and very convenient.

Edit
Sorry I see you say that the 50-500 is too heavy, pls ignore my post

I've tried it on the K5 and it works, he has subsequently update the software but advised that he was going on holiday and would only make further progress on his return

The Arctic Butterfly will also throw "big chunks" (relatively speaking) in weird places. There is no free lunch anywhere.

Yves, do you use the Arctic Butterfly whilst it's spinning

Hi, here was my solution to the problem, overkill I know.

Greg

Seeing as I intend keeping my K5 for ages it'll be worth spending time in getting the various focusing modes set-up as accurately as possible.

These are my thoughts on how to tackle it.
I believe that the most accurate focus indication available is the magnified, manual focus, live view procedure, so every other focus method must be compared back to this setting.

The next step would be to adjust, if necessary, the shims for the split screen focusing screen so that it confirms focus at the same point as live view.

Now setting the AF sensor and indicator hex ??

MANUAL LENSES FOCUS FIRST
I visualise taking my most used manual focus lenses M42,K,A and M mounts and try and find a common Back/Front focus (All lenses) adjustment for them which will activate the focus confirmation hex in synchronisation with the split screen and live view focus points.

AUTO FOCUS LENSES
Having set the base B/F setting above it will be possible to adjust each recognised AF lens individually to match the split screen and the Live View focus.

I'll never achieve perfection but am trying to minimise the error.

Some feedback to clear my mind would be appreciated.
