Did I mention I was in Tipp last weekend?

Well, on the way home we passed through Cashel. Now those of you with an Irish bent will know it for the big castle place on top of the rock. Those of you who don't will find out more here.

I wasn't able to stop for more than a few minutes, and it was the day after some big fireworks show so the place was chaos. It did, however, seem like a good opportunity to try out my new 10-22mm wide angle lens.

I didn't have a whole lot of time to set up or take pictures as I'd my wife in the car, and this (though not great) is the best I got.

However, what it does show is just how wide 10mm is. Even on the APS-C* sensor in the 400D it's still pretty impressive.

I'll try to do a more formal review of the lens itself after Easter, but my first impressions are it's well worth the money.

*I'm still getting to grips with this full frame versus APS-C stuff, but here's what I know so far. Digital SLR cameras can either be full frame or reduced frame. Basically, the sensor in them is smaller than the equivalent bit in a film camera. When it comes to my Canon, it uses an APS-C sensor, a full frame sensor is 1.6 times larger(?). As a result, when I talk about a lens at 10mm on my camera, the equivalent size on a full frame camera would be 16mm (10mm * 1.6). I believe the entry level Nikons are 1.5, but don't quote me on this.

Full frame digital SLR's are available, but are expensive right now. Of course if you're a camera company and you're reading this, I'm always available for sponsorship!
