Hi Ray,
you managed to get the middle one in focus.
What did you do different?
I have terrible trouble getting digital pics in focus. Even my SLR gets me spitting pebbles when I see the results on the big screen.
And yet the analogue cameras I use are no problem, even to the extent of selectively focusing on the wanted parts of the view.

This is very much off topic.
Does it deserve a new thread where all you experts can contribute?

Andrew,

I had that problem also for a long time. Now i know that most digital camara's have a button with an icon of a flower (tulip). Since i push that button, the results are amazing. That button is for kind of close-up foto's.

Give it a try!

I agree with wim, Andrew. You should get it in 'macro' mode. It will focus probably on whatever is in the center. A trick is to hold down the shutter button but only about halfway for it to autofocus. Once it locks on then you can move about and anything at the original autofocus distance will be in focus, the rest blurry.

I third it, before I fell on hard times and sold my D80 I was in the habit of using macro whenever the subject was within 4 feet. Their idea of near field is very liberal...

Other than that I liked to leave it on full manual most of the time, so long as you're shooting still life just make sure to take lots of backups on varying settings. Then you can have your pick of the litter.

Default Mono Blocks with TDA 2050

Here are my TDA 2050 mono blocks.

I was inspired by Thomas Bethe, he allready build this amp.

The transformers are nothing special, but will do the job.

Each mono block uses 2 pcs 22.000 uF for the power supply.

The TDA is running at + / - 25 V.

The TDA Chip sits right at heatsink.

All Caps are WIMA and Cerafine.

I have add a DC protection, because the TDA have no protection.

I keep the signal path short as possible.

The sound quality is very good, even for this low price.
