Default 2 quick questions from a newbie

In a 1600 x 1200 shot, would a 4mp and 5mp camera produce the same amount of detail?

What is the magnitude of difference between a F1.8 and F2.8 for low light shooting?

I'm trying to decide if the 5050 is worth the added expense over the 4000.

Thanks,
Steve L.

Lodewick,

1600x1200 is a 2 megapixel shot. For pictures this size, it makes no difference if you buy a 2, 3, 4 or 5 mp camera - all other factors being equal, the results will be the same.

The difference between 4 and 5 mp is only significant if you use the maximum size of which each is capable. The most important reason for using higher resolutions is if you want to make large (10x8 and bigger) high quality prints. There is no point spending money on a 4 or 5 mp camera if you only ever use it at 1600x1200.

The difference between f1.8 and f2.8 is pretty much a factor of 2, i.e. an f1.8 lens lets in about twice as much light as an f2.8 lens when fully open. Looked at another way, it's the same sort of difference as that between using an ISO setting of 200 rather than 100 or a shutter speed of 1/30 second instead of 1/60. In practice this will only make a difference if you want to take a lot of low-light hand-held shots without flash.

fenlander,

I will be shooting a lot in local bars and on the city streets at night. I'm trying to decide if the 5050 is worth the $300 extra over the c-4000. What do you think?

Lodewick,

3 low-light-related reasons I can see to prefer the 5050 (in addition to the faster lens):

1) IR Remote control - vital for working on a tripod (none on 4000)
2) AF-assist light for focusing in low light (none on 4000)
3) hot shoe for external flash (4000 needs an expensive bracket)

If low light work is going to be a major interest, I'd go for the 5050.
