First Impressions of the Canon 17-55mm IS

I haven’t done any serious sharpness testing of this lens yet, but so far I’m really liking it. The f/2.8 aperture through the zoom range, the quiet auto focus and the image stabilization are all fantastic.

Or what about this shot through our bedroom window? 17mm, which normally needs 1/30th of a second to be sharp hand-held. Here I got away with 1/3rd of a second, leaning my hand against the window frame.

That one third of a second feels like an eternity when you’re holding the camera and hear the click … … click.

BTW, if you can explain why the frost is on only one side of the tree branches I’d be very grateful. (It is frost, not snow. And the wind these last few days has been basically non-existant.)

I was also able to shoot a perfectly sharp photo of my wife pulling a silly face in our bedroom, lit by nothing but her computer screen and a 40 Watt light-bulb. Admittedly at ISO 800, but it would have had to be ISO 6400 with my old lens. And my camera only goes to 3200 …

Summary: Looking forward to using this lens for a long time to come!

    Perhaps because the sun has been shining more on one side of the tree? Just guessing. 🙂

    Well these days were very cloudy and there wasn't really sun on any side. Also the sun moves constantly (or so I've heard), and the frost kept growing on the same side for at least three days.I'm leaning more and more to a very slight breeze as the answer.

    You are right. From http://en.wikipedia.org/wiki/Hard_rime:"Hard rime is a white ice that forms when the water droplets in fog freeze to the outer surfaces of objects. […] This fog freezes to the windward (wind-facing) side of tree branches"(rimfrost)

    Wow, nice! Never thought of actually looking it up …
