If the terminology is confusing to you, you may do well in reading up on the basics of exposure (shutter speed, aperture and sensitivity). This will give you a good background on what lenses are able to do well in low light (like indoors) and how this is done.
Thank you for your reply everyone.
Hello Ash, you may be surprised to know that I am from Brisbane.
This lense apparrantly is new and was on show at Las Vages around $299 USD.
It does let more light in and around 25mm in depth. The normal lense is attached to it.
Thanks heaps
