The advent of the Olympus and Panasonic mirror-less cameras - the micro 4/3 system - has seen some amazing lens performance from the two manufacturers. Each have unique focal length and aperture combinations as well as shared equipment. There are special features abounding , yet there is one thing in common between them - a common mount and operation.
Now there is a third alternative - another exclusively Japanese manufacturer has taken options on the mount design and operations - Sigma is in the game.
And in a good way. Sigma is making three micro 4/3 lenses in prime form that are proving to be superb in terms of resolution and colour performance. The new " Art " design for the barrels is very smooth and sleek and they all have the feel of quality in the focussing.
We've tested them here on our cameras and our Olympus expert, Gavin, has had a chance to go head-to-head with equivalent Olympus lenses. Even he is impressed.
I am hoping that they also take up options for Fuji X mount and fill in with these focal lengths. I use a Sigma currently on an APS-C DSLR and am more than happy with the performance.
