Tripod collar on the 300, 400 & 500's

Is the tripod collar removeable on the big white telephoto lenses? Thank you.

No, it's not. The foot can be removed from the collar, though (4 screws).

There's a 500/2.8?!?   :P

Thanks Neuro. Yeah, you're right, I geeked. I forgot the 500 & 600 were f4's, but you knew what I was talking about. You know we did rent some 500's last November but never took them off the tripods and I couldn't remember if they were removeable to lug around hand-held. Thank you.

... if they were removeable to lug around hand-held.

You'd not want to 'lug it around handheld' without the tripod collar, IMO. The tripod foot makes a great handle.

Neuro, have you used the 400 f2.8 and the 500 f4 and if so, why is the 400 roughly 4 pounds heavier? Is that 2.8 glass that much of a difference? The 500's are BIG and heavy, we'd like to get 400's but the weight....phew! Not to mention, the price...

400/2.8 = 143mm diameter front element, vs. 500/4 = 125mm.  A 14.4% larger diameter means a 31% larger area, and since elements aren't flat, larger elements are relatively thicker, too.  So yes, it's the glass. 

OTOH, the new 600/4 II and 400/2.8 II had some dramatic weight reductions, they're basically the same weight as the 500/4 MkI (the 400 II is 20 g lighter, the 600 II is 50 g heavier).  That's thanks to fewer elements (including elimination of the protective meniscus lens in front of the front optical element) and more titanium in the construction. The 500/4 II shaved 1.5 lbs off the MkI (decent, but much less dramatic than the others - the 500 lost 8% weight, the 600 lost 28%).  Of course, the cost went up. A lot. Bottom line, if you can handhold a 500/4 MkI, you can handhold the 400/2.8 II and 600/4 II.

I guess we want our cake and a lightweight cake too. Thanx for the tech response, as always, much appreciated. Who knows what we'll do, besides keep shooting with our current awesome equipment. Have a good weekend.
