So when you adjust the focus setting are you adjusting the position of the sensor, or the setting of the AF system?

If the latter, then manual focus should always be spot on and would offer a double check as to whether the system or the technique was out.

You wouldn't, but hand held is never rock solid still. A heavy tripod might be.

Agree with George that there's no problem using Pentax cameras with studio flash. We use an IR trigger to fire the flash and it works 100% with no problems whatsoever.

How did you do the conversion?

Because after manipulating the image some values of pixel are entirely missing, hence the comb effect. If taken too far, this would be seen in a print as a form of banding in areas of gradation.

Unfortunately not! We might be selling a SMC Pentax-FA 100mm f2.8 Macro at some point, but that's not decided yet.

All digital images shot with all cameras are naturally a little soft and all need some sort of sharpening. It's much better to go the Pentax route and do that sharpening in the computer rather than sharpen in camera like Canon do. The subtelty available from the computer is far superior.

Basically we have far too many lenses and I want to re-invest in some other Pentax items. I've decided we can use our 50mm f1.4 when we do low light work and the luxury of having two fast lenses is an unecessary one. It's a matter of priorities. But yes, it's a lovely lens and second to none in terms of quality of results and manufacture. The quality of the engraving on the aperture ring has to be seen to be believed!

The header says it all. A black version of the 43mm f1.9 Limited Lens, in as-new condition, hardly used at all. Complete with all original accessories and box.

The people are a very nice touch and make the picture. Without them it would be a bit drab. To tighten it up a bit I would have preferred a less bright background and a bit more contast and "bite" overall. The composition is fine but distracting background details are best avoided.

You obviously have a keen eye and as that progresses you should be posting some terrific stuff on here!
