Wow....3 year olds playing soccer....that should be a sight. Absolutely the time for a photo.
The digital Rebel would be a good choice. I would get the kit version that has a zoom lens with it. Then you need to buy a fast lens. But fast zoom lenses are EXPENSIVE. Buy the standard (non zoom) EF 50mm f1.8 lens. You can probably find that for about $100.
When used with the Rebel, it will perform the same as a 80mm lens. Due to the difference between the size of the sensor as compared to the size of a 35mm negative.
An 80mm lens if perfect for portraits and should serve well on the soccer field. The f1.8 setting is good for the those night shots and it is helpful with portraits because it can produce a short depth of field. That way you can cause the background to be out of focus and less of a distraction.
The confusion with f-stops: A large opening (to let in more light) is a small number (f1.8). A small opening to reduce the amount of light is a large number (f16).
You can also increase the amount of light going to the cameras sensors by changing the ISO setting in the camera. With film cameras you bought a faster film. With digital cameras you raise the ISO setting. The Rebel has quite a few ISO settings.
Im new to digital / photohraphy in general.
Im kinda confused because Ive used the point and click so long I can take pictures in my sleep.
Okay so if my 3 year old is at soccer practice and I want to capture him and his buddies...
Is the f stop what Im concerned with and do I want that to be high or low?
My other concerns are night photography and portraits.
What lens would you reccommend for each. Why are you reccommending those? For which would I want a small fstop and which would I want a larger fstop.
At night do I then want to let in more or less light? IF Im capturing streetlights etc... And if less or more how does that relate to fstops?
Thanks a TON
