Can additional lens be attached to Dimage 7i?

Hi....
Can additional lens be attached to Dimage 7i?
Seen threads selling lens for various body mounts.... wonder if additional lens can be used for Dimage 7i..... If so.... which type can be used?? How to know if the lens is compatible?
Anyway.... attaching the additional lens is for wat purpose?
Seen lens like 28-70mm or 80-300mm..... wat are the diferences?

I have attached a UV-filter on the lens of my filter.... if I wish to attach a circular polariser... do I have to remove my UV-filer and then attached the cir-pol or I can juz attach it over the UV-filer to achieve the same effect?

Those are interchangeable lenses for DSLRs. For the D7i, you can only add-on lenses like teleconverters, close-up filters, etc.

It's best to remove the UV filter because having adding on more glasses only degrades image quality. That said, it's also fine to attach it over the UV filter.

Hi,

just a note...there will be vignetting if you stack too much.

Especially with the 28mm f length it's hard not to get vignette.
