Hi, i'm a noob in photography. I was reading about lens and came accross the Four Thirds System.

Would like to know how does this lens compare to other brand like Canon and Nikon in terms of price, quality, availability, variaty ......

Price wise will be more expensive than other types of lenses due to low demand but quality wise should be at par if not better to some other brand models.

So far only seen a handful of these lenses on display. Hopefully Malaysia will bring in more affordable Four Thirds lenses made by Sigma.
