Good point on the memory card. I realize now the ISO number is speed, because I rber that from the old film days. What determines how low of light will still give an adequate picture? Isn't that F rating on lens?
That depends on aperture (f) higher ISO will compensate to a degree but at a cost. Higher ISO in low light can produce noisy or grainy shots. higher ISO allows a faster shutter speed. Not an issue if using a tripod but can be if shooting handheld
Unlike aperture and shutter speed, ISO doesn't control how much light enters the camera, but instead controls how sensitive the camera is to the light. The higher the ISO, the less light needed to create the image because you are increasing the sensitivity of the sensor. But there is a price to pay at the higher ISOs. You get more distortion. The best is to use the lowest ISO you can to get the acceptable image. The camera you want should automatically do that for you. You can over-ride it and go higher but will get more noise in the finished product.

Correct , the aperture does.
If you shell out for Sony's A77, ISO concerns are minimal as it's capabilities are phenomenal.
Aren't digital cameras great? I remember having to switch from 100 film to the faster 400 film when I went to Mosport for the bike races. You know, you'd set up your camera the best you could to attempt to match the lighting conditions, but then you had to cross your fingers and wait for the prints to come back to see how well you did. Soooo much easier now.

One thing that should be mentioned, and I'm not sure if anybody else has covered it; You should ask yourself what it is you're going to be photographing and how you want to use the camera.
The Nex Has great reviews however there is one feature missing that (to me) is very important which is the lack of a viewfinder. If you're a diehard it may be an awkward switch. Shooting in sunlight may also be a problem when you cannot accurately see what you're about to shoot through the LCD.
If you're looking for a great pocket size camera this is it. DSLR Systems are great for superior control and manual focus, but the variety of lenses required for specific needs becomes cumbersome to carry not to mention expensive.
It would be nice to have both. For me it's iphone or dslr. For every day and web stuff my iphone is great. I take pics, email them to myself. When I get on my desktop, I save them to PS. So convenient and great web quality. I have a clip on wide angle/macro lens to get a little fancy with it if I want. X2 on the viewfinder though.
Obviously by my postings, I'm not an avid photographer. To me, one of the most important things is size.I want a camera that I can still put in my pocket, but still have the luxury of a lager lens. I will never take pictures in manual settings, so I don't need all the bells and whistles that I would never use. Thanks for all these great tips. Much appreciated because most of the things you've mentioned I wouldn't even think of.
