500 f4l ii

[Xenedis]

I've seen nuclear powered aircraft carriers which are lighter than the old 400/2.8.

Yes, at 5.3kg it's not light.

The mark II is seriously light by comparison. I can easily hand-hold it, whereas the old (current) model is monopod material.

But Shelly's 400 is the 5.6, Xenedis

Oh. I didn't realise; I didn't see her mention that lens, and I assumed she had the f/2.8.

If that's what she has, then any super-tele will be very heavy.
