Not my experience with Sigma Tele zooms. Lens get warm but thats about it. Far from melting.What, and have them melt like chocolate pretzels in the sun?

We are calling this new 70-200 and 'extending' lens. Perhaps in reality, its really a 'collapsible' lens! [..]
Or if they decide to make this a Red ringed DO lens.Unless Canon had invented some special stretchable material, it was expected.
I second the opinion about ISO. Just came back from a kid's bday event (a challenge in itself with 2-6 year olds..hhehe the munchkins made me work for my images..bless them) I was more focused on reducing ISO and balancing my flash output at high speed sync when they were jumping and running around. For me, reliable auto focus and low noise are the biggest needs at events, irrespective of the sensor capacity in low light. Especially since I shoot crop sensor to keep the weight down.Portraits wide open, same distance to subject, not only have more subject/background separation and creamier bokeh, but a more appealing luminosity to skin tones. At least comparing the ef 70-200mm f/2.8L IS II to the older ef 70-200mm f/4 IS. This makes it worth using the 2.8 for portraiture, though for family traveling I'd never bring it.
And for me, personally, even with great sensor performance these days, I'm always looking to lower my ISO, all other exposure factors considered.

Are we holding our breaths to see how well this lens handles focus breathing ?
You're obviously not a sports photographer, where lowlight at indoor sports is a constant problem. ISO 6400 vs 12800 is quite the difference, 1D series or not. Also, the isolation.I've never quite got how in the 70-200 range folks lust after the 2.8 when there's hardly any noticeable difference between the 2.8 and F4?
It's not like we don't have the available extra stop of ISO to bump to. (Unlike the days of the 1Ds3) and the F4 is half the weight. Unless it helps the AF speed I guess.
Shocking statement.I've never quite got how in the 70-200 range folks lust after the 2.8 when there's hardly any noticeable difference between the 2.8 and F4?

I trust that was a bit of a provocative post by wockawocka. Likely just to steer some conversations and get people to postShocking statement.
I don't think focus breathing and dust have anything to do with each other. However, dust can be a problem when it turns out to be mold spores. In some places, lens fungus can be a real concern.I'm sure it will be similar if not the same as the 100-400 II. Why does that matter anyway? I have no issues with my 100-400 II after 4 years now. And yes there is a bit of dust in it, but who cares? it means nothing.
Unless you're one of those that losses their mind when they see a dust spot inside the lens.
Yes, that's actually a bit of a disappointment, looks like a step back wards...along with the huge amount of rotation on the zoom ring.that material called DO in Canons talk
On another note : the second ring... is that a manual focusing or control ring?
One of the main causes of lens fungus is darkness. Putting a lens away for 6 months plus in a lens case is really unhealthy for lens optics. Leaving them out with the caps off for a few days at a time allows microscopic fungus to be killed off by UV rays.I don't think focus breathing and dust have anything to do with each other.

Canon EF 100-400 L lens fungus attack
note – this is a Mk 1 version of the Canon EF 100-400 L A working photographer uses their lenses all the time and probably never runs into this. I was into bird photography for a while, about…www.richardmudhar.com
Short MFD's are only useful if the Min Magnification stays the same. But unfortunately lens focal breathing usually dictates that the MM stays the same.Mfd of 0.7m is definitely one! Portability another.
