I should have said contactless tubes, sorry.

Certainly works with my Vivitar macro, but obviously fully manual and would limit things outside of macro. No problems with the focus drive running here, so lenses obviously differ.

What about some tape over the contacts?

I'm happy to make it 7pm in this instance to avoid any confusion, especially as I didn't set the closing time in the first place

Not that it looks like we will be overrun with entries......can't see hordes of people rushing home at 5.30 (GMT or BST) to enter.

Don't confuse things even more! I'm already worried enough that I'm not up to the task of judging a load of photos from photographers who are clearly better than me

You could, of course, do what Charlotte has helpfully suggested to me for the exact same problem with my new Vivitar AF macro with no MF switch and put a small extension tube on the camera first to disable the contacts.

Presumably it would mean manual only and would limit the focus range, but it does work. I can now use an AF lens with no MF/AF switch with the camera body set to AF and CIF works perfectly.

Lens received today, well packed and in perfect condition. Thanks.

Just get a nice cheap M or A prime. Works perfectly with them for very little money.

Thanks - any way with a remote control?

Thanks John.

I can do that as long as I keep the button depressed. It won't fully depress until focus is achieved.

What I'm after, that others seem to be able to do, is a way to fully depress the shutter button, remove my finger, then have the camera fire when focus is achieved, so that I can leave the camera on a tripod in a likely position.

I've been using my K-r with a 50mm 'M' lens plus tube for macro recently making a fair bit of use of the catch in focus mode.

I was wondering if this mode can be used to trap an insect ie. leave the camera on a tripod focused on a spot and wait for something to fly in, triggering the shutter. According to lots of articles on a search it can, but I can't get it to work.

As far as I can tell catch in focus should work by pressing the shutter button down fully, then focusing to trigger the shutter. It only works for me if I hold the shutter button down and focus. It won't work if I take my finger off the button. In other words the button isn't depressing fully until the camera achieves focus.

As far as I can tell everything is set up correctly. It's in AF mode, with AF-S and catch in focus set to 2.

Doesn't work properly with any of my manual lenses.

Any help or advice appreciated.

Hi Jacqui

Just for your own protection I'd return it formally using the Paypal 'not as described' process, rather than just send it back.
