Re: [LUG] Camera choice

 

Hi All

This looks like it is going to be a list of people's favourite cameras, so I 
felt compelled to join in.

On the Linux front, most cameras look like a USB drive these days, as others 
have pointed out. I use gimp for any modifications (eg. cropping) that I need 
to make.

Which camera you buy really depends on what your needs are. I've found that a 
small compact camera can be carried around in the pocket, so I always have it 
on me. Anything larger and you tend to leave it at home.

Most people think that megapixels are everything. However, the size of the 
sensor is important too. The smaller the sensor, the more noise you get on 
the image, so compacts will always be noisier than cameras with bigger 
sensors.

Another limitation is the dynamic range of the sensor. With 8-bit images you 
get a very restricted range. I hope that the market will move towards higher 
dynamic range cameras. Consumer products are all 8-bit.

The zooms available on compacts come in 2 sorts. Optical and digital. Digital 
zooms simply trade off zoom against pixel resolution, so you rapidly get an 
unusable image. Optical zoom does not suffer from this. I would recommend the 
Ricoh Caplio R6. At 7.1 x optical zoom it is way ahead of most other 
compacts, most of which are 3.5x. Also the widest angle is better than most 
at 28mm (35mm focal length equiv.) rather than the more typical 35mm, giving 
you a wider angle of view. It also has exceptional macro - you can focus down 
to 1cm from the subject, and it gives very sharp pictures. This is the first 
camera I've owned that can see better than I can. If I can't make out a 
signpost in the distance, I simply zoom in on it. Bigger cameras will give 
you better optics, but I don't know of a better compact in this regard.

If you are doing lots of low light work, then an image stabilizer of some sort 
is a good idea. This can extend the usable slow shutter speeds right down.

The flash is not great on this camera, and the sensor is a little noisy, 
especially in low light, but overall I would give it top marks. The optics 
are remarkable.

I disagree with the last poster about needing a viewfinder. I never used it on 
my last camera, and don't miss it now. I think it is better to see what the 
photo will actually look like. Live histogram display is useful here for 
getting the exposure right. He is right about the display using up more 
battery life, but I can shoot all day, 800 photos on one battery. I didn't 
bother buying a spare.

Most of the time you can leave it on auto, but you can choose the usual focus 
lock, metering modes etc. that you would expect.

The Ricoh does not run on AA batteries and does not charge over USB, so you 
will need a mains charger. But the charger is reasonably small.
