The shutter speed has to be no faster than the "flash synch" speed, or 1/180 second for Pentax cameras.

The easiest thing is to set the shutter speed in manual and then set the aperture according to the flash output. You can use a flash meter, but if you start at f8 and then see what happens, you can lighten pictures by opening upo (f5.6..f4...etc.) or darken pictures by closing down (f11...f16...etc.)

With shutter priority the camera will want to adjust the aperture according to the ambient light, which isn't suitable for using studio flash.

Hope that helps!

I'm afraid that it misses the point. AA produced absolutely stunning prints of a quality that is breathtaking. This is something that cannot be reproduced on a monitor and needs seeing "in the flesh" to fully appreciate.

The officially printed books are pretty good, although some of the subjects are of course quite mundane. The unofficially printed books can be good, but they are not of the same standard. The best ones are actually duotone printing.

I have seen black and white prints of the highest order, not AA as it happens, and they are so far removed from the images that we see today. The richness and depth of the blacks and the delicate transparency of the highlights make these sort of prints objects of beauty in their own right.

The two images posted above have none of these fine qualities and whatever their origins they are just really poor reproductions.

I'm no airshow expert, but it strikes me that manual focus might be easier than AF. Especially as the subjects are at some distance, so the amount of focus travel needed will be quite small.

Failing that, what about using trap focus with a manual focus lens?

The price starts at what a seller asks for, but the final sale price is what the buyer is prepared to pay and the seller is prepared to agree to.

A guide to prices can be found by searching eBay and Amazon and looking at all the adverts in AP.

Probably wise on here to check the SRS price as well before posting.

I remove quite a few posts from Classifieds when they stray from the point. Not all of them because some are harmless. But when they clutter or impede the sale they go.

However, if I'm away from the PC for a while sometimes it's too late or becomes irrelevant, especially if the OP has covered the diversion or joined in.

Please use Classifieds for the buying/selling process. Anything else may be removed without notice!

Link to the offending site removed. If the advert offends, then not linking to it seems best.

Adverts are provided by Google and PU has no input. The type of advert shown does vary depending on the users web history, so not everyone will see the same ones. That's how I understand it anyway.

Most forums carry these adverts and it keeps the content free for all of us.

Thank you for that. Sue did her bit as well. I make the books, she does the slide shows, we both shoot images.

This has been a very busy weekend, but fun was had by all.

The link takes you to my new photo book on Blurb. Wedding was Saturday, images processed Sunday, book made Monday. Mark is my Brother-in-Law, so a special effort was made to get this out into the public domain!

Sadly the first upload failed, so another 257.4MB was started just after midnight. That's why I'm posting this at 1.45am!

It was a terrific Medieval Wedding, but I'm very, very glad I decided not to wear the chain mail. Those who did were absolutely filthy by the end of the night from the oil used on it. If I'd had that muck all over my camera gear I would not have been happy....

Fair point, I'll mention it.

Yes, I meant in terms of side to side, but perhaps I didn't put that very well...!

But Peter has made the point.

Testing collimation and focusing accuracy is a laboratory standard evaluation IMHO. I'm quite sure if I bought a second hand K10D and was told the focus had been adjusted by the user I would be checking it out very carefully.
