Rats sharp macro

I own the lens now for some time and I am absolutely convinced - it is Rattenscharf. I've had several macros in my possession and I'll give a them, they are just about all very sharp. So this here which also still is the first macro in the Canon camp, which has an IS, plus the new Hybrid IS. This makes for a 4-stop shutter speed when using the lens outside the macro range. With a magnification ratio of 1: 2 there are 3 stages and at 1: 1, there are 2 steps, so you should keep in mind that you can not use with its full 4 steps in the macro range the IS. The IS can be quite handy in the macro range, which does not mean that you from now on for macros requires no tripod. After all, one must also Neat dim when at close range would achieve a good depth of field, as the shutter speed may like to extend beyond the boundaries of the IS.

The image quality is excellent and is very sharp as one would expect even from a good macro at open aperture, in this regard, there is absolutely nothing to complain about. The Bokeh is the 9 rounded diaphragm blades so soft. The autofocus is quick and quiet, and can be limited in 3 stages.

The build quality is top despite plastic tube and feels very high quality and robust. Similarly, the grip focus ring can be rotated pleasant and accurate with no play. That's very important to me because I often sharp point manually in macros, here I insist on a non-slip ring can be rotated accurately and softly, not somehow with some larger force or Ruckelhaft. The lens is dust and splash-proof, but what is the number not only think of the simple rubber ring on the bayonet, but there are also seals at the counters, focus ring housed only the rubber ring on the bayonet makes a lens is not tight. I would also like casually mentioned have not all L lenses are dust and splash-proof as well as many think.

The lens has an internal focusing system, so it moves when focusing anything out or purely what I appreciate with every lens which has the very. The surface of the lens hood was finally revised and is now Matt, in the previous lens hoods scratches were always very fast clearly visible also even fingerprints.

But a really great lens for the macro area that you can use without problems as small or telephoto for portraits.

Small note on my part: Those who wonder why the lens when light shaking gives a discreet clacking of itself, which seems to be normal. However, if it is clear and you feel has the perhaps slightly loose inside that will come through the IS. The IS runs after use still for a moment and then fixed his lens, the lens who separates from the body at that second, prevents the lock of the movable lens. This becomes noticeable by then the this looseness in the inner back and forth bangs, you can see that even if you look purely from behind. Just once more turn the lens on it and the IS activate where you half press the shutter button and then let the time expire IS. But does not happen because the IS only a second or so lags, but maybe someone will come times shortly before unscrewing the trigger normally. But is also in the instructions that you must not disconnect the lens while the IS is still running.
