Welcome to the forum, Monobod, glad to see you arrived here safely!

You need to find a place on the web such as bBase to place the images so you can lonk. The large photos on ePHOTOzine will also link, but I don't know if the small ones will.

For simple and effective intra-oral photography Kodak do a very nice little kit including one of their 7.1MP bridge cameras. It includes close up lenses and ring flash and even a printerdocking station.

Current offer price is £895 + VAT - if you want to know where from a PM will give you the answer!

I was looking at a Pentax Dental Kit today, and what an impressive bit of kit it is.

Based on the SMC Pentax-FA 100mm f2.8 Macro, with ring flash, close up lens and an incredibly smart dark grey hard case doscreetly emblazoned "Pentax". I'd love one of the cases....

This particular kit is no longer available, but what a shame as it's a cracker.

Sorry if we missed your post, don't know how that happened. You'll probably get masses of replies now.

To be honest I don't think there's a lot you can do apart from what you've already done. If it's under warranty then return it via the shop you bought it in, if it's not under warranty check out the price of buying new before you commit to spending an unreaslistic amount of money getting it repaired.

Hope that helps.

Nothing wrong with a fine Claret. In fact, quite a lot right with it...

It's also worth noting that guns with the same name and model number have been known to have widely different voltages. Vivitar changed their 283 at some point and we have measured 270V with some and less than 10V with others, apparently identical otherwise.

In practical terms, this is an erroneous argument. I understand what is being suggested, but at normal distances it isn't relevant IMHO.

The use of the central focus point followed by recomposing works just fine even for the most critical applications.

For macro work, on a tripod, manual focus is the best option in most cases and the relvant part of the screen is where we look for sharpest focus.

In photography, sometimes the simplest of things can be made complicated quite unecessarily.

Set the focus point to centre only, focus/lock and then recompose. Much easier.

On a tripod, use manual focus, much easier.

Glad to hear it was helpful. Just keep on gathering informtion, try everything for yourself rather than relying on others' experience and it will eventually all click into place.

There's a long learning curve, but it's great.
