I PM'd here as well.

Whoever it was that deleted AuraTodd's thread with a plea for help and advice, you should be ashamed of yourself.

She clearly has few friends from whom she can draw comfort, but she counts us among them.

I hope you receive the same treatment as and when you ask anyone for help.

Do you have any idea the trauma you could be putting her through now? I doubt it.

She may not even have had time to read the sensible advice in the replies. You could.should have left it a bit longer at least.

Whoever you are, I'm disgusted and this might just be the straw that I need.

I'm now thinking that your "everything looks blue" problem is possibly condensation on the front element of the lens.

If I'm right, and this 'blueing' happens regularly, I suggest you don't try changing lenses until the temperature of the camera has stabilised, otherwise you risk moisture laden air entering the camera body.

Yes and yes, but make sure you get a set of tubes that have all of the pass-through electrical contacts.

On the macro lens front, my suggestion would be a minimum focal length of 90mm if your subjects include insects/bugs.

Moisture in air condenses on surfaces that are cooler than the air itself and forms a thin film of tiny water droplets to appear on the cooler surface, just like your bathroom mirror after a shower.

If your camera is at 60F and your bring it into an atmosphere at 78F and 28% relative humidity, water will condense on all surfaces of the camera. If left to itself, the condensation will disappear naturally as the camera temperature stabilises with the new ambient temperature.

When this 'blue' phenomenon occurs on the rear screen, can it be cleaned off with a tissue or cloth?

Viewfinder turns blue ? ? ? Must be lens or mirror related then. How's the humidity in california if that's where you are right now? Could there be a small amount of moisture inside somehow?

I don't know if it's been said already because I haven't time right now to read the whole thread. but have you considered a K-5, K-5II, or K-5IIs instead of a K-3, and a macro/close focussing lens?

Also, there are other closer focussing options like the Raynox Macro Adapter and/or extension tubes.

Apologies if these have been mentioned before.

OK, I had assumed that since your original post was about the 1.7x AF adapter, as were all the other posts leading up to your second post that I commented on, I thought that you were referring to it's use on a K110D.

This site is clearly wrong then.

You're right about there being no duty on cameras. News to me though and apologies for the misinformation.
