Spyder auto-focus calibration
Interesting bit of kit, but €49 + VAT? A bit steep I think. I haven't found any solution to B/F focussing that describes how to correctly adjust the camera when a zoom lens is used. Would you test at max. or min. zoom?

Spyder auto-focus calibration
Would you test at max. or min. zoom? It depends on how well the zoom maintains focus over the range, so I would expect an average is about the best that can be achieved. Zoom lenses are fairly modest apertures, so hopefully Depth of Focus (at the sensor) will be enough to cover any residual error.

I haven't found any solution to B/F focussing that describes how to correctly adjust the camera when a zoom lens is used. Would you test at max. or min. zoom? Peter, I have a universal correction of +150um dialed in on my K10, and that serves the zooms just as well as the primes FWIW. The zooms ...

A chap in Quebec has developed a lens calibration chart and instructions that are all FREE. Visit pentaxdslrs.blogspot.com for the download. I haven't used it yet so can't comment, but I have purchased one of his e-books and am very pleased. Regards, Stephen

Spyder auto-focus calibration
The printer quality hardly is an issue for focus calibration charts, as it is the distance that counts. On the other hand, charts for resolution measurements are different and need quality printout.

Spyder auto-focus calibration
Just stand a ruler up at 45deg at the side of a cornflakes box so that it looks similar to the Spyder in the links above. Your focus point is where the ruler passes the front face of the box.

I haven't found any solution to B/F focussing that describes how to correctly adjust the camera when a zoom lens is used. Would you test at max. or min. zoom?

Recover Photos from corrupted SD card
I would suggest that you send the card back to the manufacturer, not the seller/retailer. Then, if the card is a fake, they will know, and they might be able to recover whatever can be recovered. 32Gb cards are not exactly common so it's highly likely that you have a genuine card that is not comp...
