Patent: Canon EF 200-600mm f/4.5-5.6 IS
- Thread starter ahsanford
- Start date
Not sure if something changed with the original story over at PR, following the link in the OP.
That article clearly states this is an L lens (in the title of the article). This was dropped with the title here on CR.
Also of note, this is a non-IS lens. IS is not listed in the title nor is there an IS element noted in the patent. IS was added with the title of this post.
I didn't read all 14 pages of this so maybe this has already been discussed.
P.S. I've read a couple speculations of DO elements but there are no DO elements specified in the patent. Lookup the patent for the 400 DO II.

Sure, but Neuro and I are talking about the same thing, I think - namely, carrying round and using, with or without support. I have the 500, but use it with the 2x extender, so the weight difference is negligible (less than a pound). I am tremendously weak and unfit, but I manage. So I think we disagree with anyone claiming 'handling' (meaning hefting, carrying, or shooting with handheld) would be harder with a 600DO.

That's basically me! Except I'm younger. Ahem

That's pretty impressive handling by the looks of it - what if the wind blows? I'd love to try it out but I know even 300 2.8 X2 gets tiring for me.

That was a blustery day at Sachuest Point National Wildlife Refuge in Rhode Island – temps in the low 20's °F, winds were >20 mph sustained with gusts over 40 mph. At times I could hear the lens hood sounding like a pipe organ. Here's a shot from the day:
Not great, but then neither were the conditions. This was shot handheld with the 600 II + 1.4xIII, taken during a hike of ~3 miles, followed by scrambling down ~40' of wet rocks to get to sea level.

OK, far too challenging for me but as they say "where there's a will there's a way". Certainly good exercise!!

Wait, that was you??
And the lens hood does seem rather a wind sock sometimes.

So a photographer photographed a photographer who was out doing some photography and then posted the photograph of the photographer on a photography forum….jeez, this is confusing! ;Dneuroanatomist said:scyrene said:neuroanatomist said:scyrene said:
Yep. The photographer, not the ducks.
*Waves*
But who photographs the photographer?
A photographer friend of the photographer's.
I could imagine how it would get tiring on a long day out, it IS a monster of a lens!

My Sigma 120-300 OS (non-Sport) cost me "only" $2600 AU and the new Sport version retails for much more than that. Lucky I have the same optical formula albeit none of the other enhancements. The problem with this sort of comparison is I still find it hard to believe Canon these days will have a 100m+ diameter lens (even say 105mm and round-up numbers like Sigma) and NOT charge big-white price for it.
