Hi, any sifu please help with a recommendation?
Type of camera/lens/accesories : Compact
Budget : ~RM900 ... stretch to 1k possible
Your Location : KL
Prefe`rable brand : An
Type of photography u want to do : Insects
Any specific models in mind? : None
Any specific features u want? : Erm... very good / super close up macro mode for small samples, e.g. insects, needed to take samples for biology research.

Thanks! That helped quite a bit. If I may ask.. from your POV, what will you recommend me to get for my sis? 1000D or 450D?

1st question answered so might as well clear your thoughts.

Let's take a lens name for example:

Canon EF 70-200mm F/2.8 IS USM L

Canon: Brand
EF: Lens mount. Canon has two, EF and EF-S. EF-S can only be used with APS-C sensors (xxD xxxD and xxxxD series).
70-200mm: Zoom range. Dunno how they measure this. 70-200 is around medium telephoto range.
F/2.8: Maximum aperture for this lens. In this case the maximum aperture is same throughout the focal range, but in other lenses this may not be the case. For example, F/3.5-5.6 means that the lens maximum is 3.5 at the widest focal length and 5.6 at the furthest.
IS: Image Stabilizer
USM: Ultrasonic Meter, helps your lens focus much faster than conventional motors.
L: 'Luxury' class lens.
If you're seriously into video, opt for another alternative like the Canon Ixus 110 IS, Samsung is a hopeless brand in terms of PnS and camcorder, they don't even do marketing, so what do you expect?

I'd recommend you seriously consider HD video-capable PnS cameras, they'll do much better.
