You have got this technique down to a fine art now Gareth. Both wonderful shots but i agree that the second is superb.

Like the lighthouse shot

Good one...well done.

I have used both the DA* 60-250 and DA* 300 on the K1 in FF mode. The 300 was based of a FF design and covers the larger sensor with no problems. The 60-250 has some vignetting, but is easily dealt with either by cropping or correcting in pp. There is also a baffle-removal modification that can be done to the 60-250 to remove the vignetting altogether, details of which are available on PentaxForums, but I have yet to see the need.

As others have stated you can always shoot in crop mode if you wish.

I like all of them. My fave is the b+w of Tower Bridge

....and being a mirrorless camera presumably uses Contrast detection AF which has no need to be adjusted, like LV on a DSLR

That is exactly the FL (+ longer) where you will notice it

Yes John , I experienced the shutter shock myself when using speeds in the range 1/30-1/200. But I am talking simply about focussing. When using LV zoomed 100% the big screen on the K1 makes manual focussing so much easier than using the viewfinder. The image is much much bigger. No use at all of course when off the tripod or with a moving subject.

Ok so live View is not as accurate as the focus-rail they used in the article. But in their words "The results here [Live view] are clearly much better than those achieved by either the camera's own AF system or by manually focusing using the optical viewfinder."

If i want to absolutely nail focus to the best of my ability on a subject i will use a tripod and LV viewed at 100%. with the lens wide open if needed. Tell me a better method?

Sorry if my post was confusing about Live view. i did not mean to imply that the LV Contrast Detect system has anything to do with autofocus adjustment.

Important point to note here is that John's method has a logic because he is basing it on taking many many photos "in the wild". I would not recommend hand holding for actual AF testing which needs a more scientific approach.
