I'm new to this forum and in general, don't know a lot about cameras.
Currently I have a Canon PowerShot A540 but need to replace it as it is draining battery real fast now.
I need a camera to take indoor photos (kids at home) and I wonder which camera is better for me. I would think that PnS is more suitable and would prefer compact or ultracompact.
I read that the lower the F, the brighter the lens and hence more suitable for low light photos (including indoor?).
I tried to look at the specs of the cameras available but am puzzled about the different types of lenses. Can we just compare the F (for a brighter lens) or do we need to take the type of lens into consideration?
My A540 has F2.6, but the Sony cybershot WX100 has Exmor R lens with F3.3. Seems like Exmor R is good for low light? Then how is it compared to Canon IXUS125HS with F2.7 or Fuji F660EXR with F3.5?
In theory, I'm confused and in practical, can't really test out at the shops because in general, the shops are all so brightly lit.
Can anyone please advise? Or recommend a camera? (at least 5x optical, able to take indoor, movies....)
PS: As for the power drain of A540, it is due to wear and tear and hence need to change or is there any way to save that? thanks!
