400mm? A bit short. Get it over 427mm and I might be able to use it. Maybe even 423mm at a push.

Easily identified.

They march down the street chanting "Dona eis requiem" wearing sackcloth and self flagellating with birch twigs.

The 600mm F2 at £300 (keep the change) does it for me - I'm in.

I assume there will be a bogey (never mind a tripod) thrown in at that price.

How would a 70-200mm with a 2x TC on it compare in terms of weight, height and IQ?
Weightwise it would knock the socks off the big Sigmas, but in terms of IQ and usability (AF etc.) it would be a non starter.

Pete - have a look here. These were taken with the 150-500 which is probably not quite as good IQ wise as the Bigma.

A true zoom will retain focus as it is zoomed. This is a parfocal zoom.

A varifocal needs to be refocused after zooming. This type of lens is commonly found and is more accurately called a "variable focal length lens" - it releases the lens designer from some of the tricky design problems.
Got it. Thanks John.

Update :

There definatly is some annoying dust / pollen in there, but it now seems to have migrated to the viewfinder instead of the sensor...
That tends to confirm my reservations about blowers.

Still, at least it's not doing any harm there.

Sorry about this, but I was reading this and listening to Radio Hauraki (google it if you like classic rock) and this came on. Everyone should hear a tune this good.
