I'm keen on taking pictures so I'd like to show you that an equipment thanks
to what you can see all photos on my page.
My first camera was Beirette that cost at that time about 50 east-german mark (about 5 USD). Then after a longer time I've got a compact camera. I was satisfied but there was one big disadvantage. The compact camera has its own "mind" and you can never get what you really want.
I've body Praktica MTL3 and zoom lens Prakticar 28-70mm. I usually use a 24DIN/200ASA film with an external Vivitar 2000 flash.
Like I've already written above the body was not new. After a time on some pictures I've found some yellow smear that was caused by a light comming through the hinge of the back camera doors. Yellow color was caused by a yellow transparrent padding. I've fixed it and what was my surprise then when I've found a different smear. But the white one. I've found there a whole dedicated for a small screw but the screw was not present. Again it was in the hinge part. The solution was simple. I've placed a piece of black tape. From that time everything was all right.
The pictures of my camera were made by digicam Olympus Camedia 840L. It was really pleasant work. For the web presentation it was perfect.
In the following table you can find some measured current drain parameters.
|Ready + LCD ON||670mA||still|
|Pressing the button half way||380mA||still|
|Charging flash||230mA||till ready (>2s)|
|Viewing pictures on LCD||510mA||still|
|Communication with PC (index,transfer,erase)||218mA||just during the actual operation|
The current consumption is higher when there are more funcions at the same time.
When you will charge flash, LCD ON and you will pres the button then the
peak current will be given by the sum
Ready + LCD ON + Pressing the button half way + Charging flash that makes about 1,18A.
I wanted a digital camera with the possibility of manual setting and it was the reason
why I bouught HP 618.
It was said that the current consumption is the biggest disadvantage so I've measured it
and the result is in the following table.
|Ready||LCD ON||Switch ON||Switch OFF||Action|
|PC connect||0,27A||0.73A||1.26A (impuls)||0.57A (impuls)||0.37A transfer HP > PC||0.48A transfer PC > HP|
|Review||0,63A||0.63A||1.26A (impuls)||0.88A (impuls)||1A change to another picture (few seconds)|
|Playback||0,63A||0.63A||1.26A (impuls)||0.87A (impuls)||1A change to another picture (few seconds)|
|1.30A (impuls)||1.52A (impuls)||0.45A motor of ZOOM||0.65A half way pressing
1.0A pressing - taking pictures (2s)
