Kein Ultraschall AFObjektive mit Ultraschall-Fokuseinstellung sind meistens schneller als Objektive mit normaler Fokuseinstellung. Ein, oder mehr Linsenelement(e) mit niedriger Dispersion ist eingebautLinsenelement mit niedriger Dispersion helfen kromatische Aberration zu minimieren. Nicht stabiliziertImage stabilization helps to reduce blur caused by hand shake, especially at high focal length or in low light situations. Image stabilization can give 1 to 3 stop advantage over none stabilized lens, based on the reciprocal rule. MetallbajonettPresigünstigere Objektive haben meistens Plastikbajonetten, während teure, professionelle Objektive mit Metallbajonetten ausgestattet sind. Im Allgemeinen sind Metallbajonette dauerhafter, und praktisch wenn die Objektive oft getauscht werden. Wenn ein Kamera meistens nur mit ein Objektiv verwendet wird, speilt das Material des Bajonetts keine wesentliche Rolle. Keine interne FokuseinstellungDie Länge von Objektive mit interner Fokuseinstellung bleibt unverändert während der Fokuseinstellung. The front lens is fixedThe fixed front lens is not rotating during zoom and/or focusing. This allows the photographer to use petal shaped lens hood. Fixed front lenses also make the use of polarization filters a lot easier. WetterfestWetterfeste Objektive sind staub- und spritzwasserresistent. Obwohl sie nicht wasserdicht sind, können sie im Regen oder unter anderen feuchten Bedingungen benützt werden. Einige Dichtungen geben nur Schutzt gegen Wasser oder Staub, und nicht beides. Die Resistenz gegen Feuchte und Staub kann nur ausgenützt werden, wenn das Kameragehäuse auch entsprechenden Schutz bietet. Kein einschiebbare FilteruntersctützungEinschiebbare Filter werden bei Objektiven verwendet, die entweder zu gross sind, oder aufgrund des Winkelbereichs keinen traditionellen Filter vor dem Objektiv zulassen. Im Allgemeinen unterstützen Teleobjektive mit hochen Belichtungswerten und Ultra-Weitwinkelobjektive solche Filter. |

This is truly a gem. F2.0 ensures full control of DoF. The images it takes are razor-sharp. Very good for both close-up macro work and for portraits!

The Zuiko 50mm F2 is one of two macro lenses in the Olympus 4/3 range, compared to the Zuiko 35mm F3.5 the 50mm lens has a slightly longer focal length, wider aperture and better build quality which importantly means the lens is weather sealed when used with the Olympus E-1 or E-3.
The lens itself is relatively small as you'd expect for a prime of this type although it's slightly heavier than it looks and certainly feels well built. The design is simple with the only control on the lens being the focus ring which like most of the Zuiko Digital lenses is a focus by wire (turning this ring tells the AF motors to move rather than directly moving the lens). A focus range indicator is the only other item on the lens, this simply shows what range the camera is focussed on which is handy for working with minimum focus in macro shooting. There is a small lens hood which can be reversed for storage on the lens. On the 4/3 format the 50mm focal length equates to about 100mm.
In terms of pure image quality the ZD 50mm is outstanding, it's incredibly sharp all across the frame and is well regarded by many people. Although the 100mm equivalent focal length is a bit long as a walk around lens, combined with the F2 aperture it makes for an excellent portrait lens. Although it lacks the convenience of a zoom which I have to admit I generally prefer, the 50mm is just about always in my bag - it's so small and light that it can easily tuck into a corner without being noticed and there's been a few times where it's saved me when I've been shooting very low light concerts. I've always eyed up the 35-100mm F2 lens as it would give me the quality of the 50mm but the flexibility of the zoom however the 35-100 lens is too much in terms of size, weight and cost so the 50mm stays with me. Its weathersealing has proved itself, I ended up shooting a wedding outside for the afternoon which unfortunately (and unsurprisingly in Scotland) rained the whole time. The E-1 and 50mm never missed a beat the whole time.
You might be wondering why not five stars, unfortunately while the 50mm is a versatile lens it's very much 'a jack of all trades, master of none'. As a macro lens it is only 1:2, only with the EX-25 macro extension can it reach 1:1. The 50mm lens doesn't give much working distance which means you need to have the lens close to whatever you are trying to photograph which can be tricky when shooting insects. The ring flash oddly doesn't fit the 50mm without a surprisingly pricey step down ring.
As a non-macro lens, the focus speed and hunting of the 50mm lens can be somewhat troublesome as Olympus didn't fit any sort of focus limiter to the lens. This means if the camera misses focus it will move all the way through to the macro range and back again which is relatively slow due the lens being a macro lens. A simple focus limiter would stop the lens returning to the macro range which would reduce the problem although as long you make sure you choose a contrasty subject this can generally be avoided especially with the E-3.
Sigma do offer some macro lenses, particularly the 150mm stands out which does have a focus limiter however despite my comments above I do like the 50mm lens - the image quality is superb and while it makes some concessions it is still a good all round lens and the small size and weight means it's easy to carry around. I highly recommend this lens, while I've bought a variety of different ones this remains one of my favourites.

This is super lens, it's fast and crisp edge to edge. As a micro lens it's stunning. but I also use it for portrait and still life work, at which it shines too. A great buy.
