Was going to point that out here:

Did this hours ago when I was prompted. Didn't think to post because anyone with Lightroom should have been notified.

I like the fact that I can actually brows the library on my AMD X2 4800+ now rather than sit and wait for every line to load.

The clarity slider which seems to be a quick large radius USM (not ultrasonic motor) is handy, especially as I'm not very good at using the new USM like sharpening (I make a real mess, plus most photos really don't need it).

Supersonic Drive Motor (SDM) support for the new lenses.

I know, that memory card is very small, just 6 images to start. Battery life is terrible at 60 seconds and goes down every time...

Yes but that is an EOS 400D...

You crazy man!

Aye...

Plus, I didn't know Canon has Liveview

I think 3 and 4 are nicest. 2 has too much DoF and 5 is not one I like at all.

Over on dpreview someone posted:

So there is a good bit of information on this lens and reviews

No, I'm sure I don't need to explain though...

Wonderful for working outdoors and it really works well. I got soaking wet in a heavy shower but all my equipment was nice and dry.

Was going to get a bag with an all weather cover but that wouldn't have allowed me to carry a hydration pack. Imagine that bursting or leaking doesn't bear thinking about...




Anyway, back on topic:

I had found a subjective review of the 18-250 in Canon mount while surfing on my PDA but I cleared the browser history so am having to search for it again and can't find it...

Which is why there are some half camera bags which are rather nice. Amazingly expensive but they are completely watertight and float.

Thought it would be best to keep my K10 and equipment as protected as possible, especially when crossing streams/rivers or in the pouring rain.

From my current use with my K10 I'd be rather happy with a fast ~20mm, a fast ~50mm and a moderately fast ~200mm and no zooms. But that kit costs more than my current zooms...

I like the look of the 18-250 and it would be interesting to compare it to the kit lens and the 50-200.
