Not really, if they are good quality. A new set of Kenko PK/AF (not really AF) tubes would have cost you around £90.00

They don't seem to be available new any more, but you may find a s/h set.

I'm not sure if the global/single (affects all lenses) adjustment and the individual adjustment are cumulative. If they are, you have a max. adjustment range of +/-20

Not as spooky as our two posts at exactly the same time . . .

Well done for fixing it.

All that is needed for this data recovery job is a cheap 2.5"/3.5" IDE/SATA to USB adapter, available for peanuts on ebay. It'll come with a PSU too, but that's only normally needed for 3,5" or larger devices. 2.5" devices will normally be powered by the USB port.

There is little or no risk of 'frying' the drive, unless you are very careless. Just remember that with the drive removed from its normal operating environment, anti-static precautions should be taken. In other words, put it on a desk, connect it to a PC, turn power on to the PC then don't touch it until the PC is again turned off.

Now enjoy drama free data recovery.

Sometimes a point is better made when, of necessity, it is written in an aseertive manner.

How much for the AF500FTZ flash?

Stefan, you need help

Back or front focussing is only a problem that occurs with the use of auto-focus (AF) lenses in AF mode.

If a lens/camera combination is back focussing (BF), when you use AF to fix the focus point, that focus point will be slightly behind (further away from) your intended focus point.

Front focussing (FF) is the opposite, the focus point will be in front of your intended focus point.

This problem is not limited to Pentax cameras/lenses, all makes suffer from it to some degree. The probability is that film cameras had the same issue, but we never new it.

On a K10D, you can make an adjustment that affects all lenses by the same amount. The K20D and K7 can hold individual adjustment data for up to 20 lenses.

This problem does not occur with MF lenses, or AF lenses in MF mode.

The DA has a metal mount, has the manual shift focus mechanism, and is supplied with a lens hood. The DAL has a plastic (Low cost) mount and does not include the manual shift focus mechanism or a lens hood.

Optically they are identical.

Nice try Doug, and only about a year late
