Canon EF 24-105mm f/4 L IS USM Lens

Just a quickie please. This lens is stated at f4. Is it only that aperture or does it alter. I was thinking for longer distance stuff for clarity really. I think it is only this one. I wonder how that might be if you were taking a picture of a landscape and wanted it all razor sharp.

Thanks (wish I'd taken up train spotting it would have been easier to understand!)

f4 is only its maximum aperture. its sharp from about f5 until about f11.

The f4 designation means that you have f4 available as the widest aperture at all focal lengths -(unlike some lenses that stop down as you zoom).
You have full control over selecting whatever aperture you want to use via the controls on your camera.

Goes from f4 up to f22 I think. Usually the stated figure is just the maximum apeture. I'm not sure what the optimum aperture is for it, but I've found mine sharp throughout the range, not just from f5 to f11.

And here I am with lens safely arrived an extremely happy bunny. Leaving it to settle in the nice bag that it comes with to adjust to my warm home from the cold.

Thank you everyone really!

Reckon so Steve. It had settled into the warmer climate so could not resist a quick go. Crikey at f4 it is a mighty tool for certain! It looks rather nice as well; makes my 500D come alive. Almost as if my cam-body had been dozing all this time waiting for the right partner. Oh to be sure, Ginger Rogers and Fred Astaire; here we go Smile

So, who did you buy it from after all?

I used hldigitalbestbuy via eBay and at 569 which included Special Insured delivery, I was delighted. I received a personal telephone call from them yesterday afternoon confirming payment and that it had gone via Royal Mail 'SID' and should be with me at first delivery. It was, packaged well, clearly brand new with a written warranty for twelve months.

Yes I could have had a proper Canon box with pictures and writing but truthfully I didn't have 700-900 available funds. I'm pleased, it works perfectly so what more could I ask?
