Had Nikon D300 and accessories (too much weight), for health reasons, switching to Olympus.
Often disobeyed company - by me - am more than thrilled.
* Lens is the ideal macro lens.
* Imaging performance of my E520 - peak values
* Excellent sharpness, therefore for Macro TOP
* Lens is not too heavy or smooth, just right
* 100mm (small picture) very good macro lens to approach not go too close to the object to have
* Macro lens typically a bit slow but still fast enough during AF
* Macro lens at its best at an unbeatable price
* Extremely good sharpness, even in landscapes, you can see every little detail
* I use this lens for portrait with blur intent because it "detail exactly 'maps
Olympus Zuiko Lenses & highly recommended who do not carry much weight and commitment to excellence, could not live without
So far, my clients have not noticed the "only" an Olympus was at work - I recommend this camera and lenses on - a rethinking has taken place with me
