Spotty-ewe asked me what camera I use - and I thought some of you might be interested - so here is a separate thread about it...
What do you use, and why?
Mobile phone cameras are good... and I can use mine to produce (RAW or TIFF) images that I can edit and manipulate on my computer... and mine has two cameras including one with a 2* lens. This is "adequate" for most pictures.
My Panasonic Lumix GH2 micro 4/3 pseudo-DSLR (mirrorless) is now several years old - but several manufacturers make cameras to this specification. This has about a quarter of the sensor area of the 24 * 36mm "full-frame" format, but is large compared to many (compact) cameras.
The main relevant questions are:
How many pixels do you want?
Do you want a viewfinder (or just a screen on the back)?
Do you want interchangeable lenses?
Do you want to use it without a tripod in low light conditions (High ISO and image stabilisation)?
Do you want to take videos?
How much weight are you prepared to carry?
What other criteria have I missed?
My camera has a high sensitivity (ISO) and an image stabiliser, so it works in low light conditions, without a tripod. I have a ten to one zoom - so the one lens is adequate for almost all landscapes.
I used it with a very fast (wide aperture) lens to photograph dancing/vaulting ballerinas/gymnasts for my late wife's school, in normal hall lighting, and with the zoom in theatre lighting.
