We dont have a cellar as such, but we do have a walk in store room, full of beer and wine

ultimababe - it is like a picture postcard when it snows and is sunny. Unfortunately I couldn't find a decent picture in a hurry, but here's the house during snowfall. It was *so* dark from the cloud cover it was crazy...

It's much more picturesque in the snow when the sun's out, though - as this shot of the garden kind of demonstrates

Why I didn't turn the camera around and snap the house at the same time I don't know

How do you calculate that

300x1.4 = 420mm, how do you get it to be 672 ?

What is EFL ?

Ya, havent had a DSLR nor SLR before, so i'm reading alot on the subject

672mm would be cool

Digital cameras that are not "full frame" (that is, who's sensor is smaller than a piece of 35mm film) have a "conversion factor" (sometimes goes by different names). The basic principle is that if a lens has a focal length of 500mm on a 35mm camera, if you fit that lens to a camera with a sensor 1.6x smaller than a 35mm piece of film you get an increased level of magnification. As such, you get an extra amount of zoom simply because the sensor is smaller than a full sized piece of film. That "focal length for free" figure is referred to as the Equivalent Focal Length (EFL).

So, with a 350D and 20D both having a 1.6x crop, you multiply the physical length of the lens by 1.6x to achieve the actual focal length you'll see.

That is how you get "compact mega-zoom" cameras. My Canon S2 IS has an actual focal length of 72mm, but because of the size of the sensor it's EFL is 432mm.

The conversion factor has it's plus sides for wildlife and telephoto shooting in general, but you do lose some of the wide end because of it. Because of the size of the sensor, my 17mm wide angle is infact 27mm EFL at the widest setting.

I hope that made some kind of sense

Nice, it did make sense, thanks.

Do you know if the 1.4x TC can be used with a IS lens ?
Having IS at those ranges could come in handy instead of carrying around a tri or monopod.

I've not done the above, but because the IS takes place in the rear elements of the lens, and you fit the TC between the camera and lens - I would be very surprised if it didn't work, but it would be worth confirming that!
