		<description>I have been trying to get a hold of 400/5.6 from B&amp;H, but been sold out for a while. Hate it when rumour about new lenses come when you are about to buy a lens in the same range :-)</description>

		<description>If you look at all Canon primes, there is a big price jump on any lens that needs more than a 77mm front element. I don&#039;t know if it&#039;s the size of the front element that makes it more expensive or other lens elements, but it does seem to be the case. If I&#039;m right, that means that a 500/5.6 would still be in the upper echelons of the Great Whites, price wise (just look at the price difference between the 200/2 vs 200/2.8)

As for the 400s, 3 in the lineup is a lot, but I believe canon still offers all four 70-200 options (4/2.8/IS/non-IS) so it&#039;s possible that canon would introduce a 400/5.6L IS along side the current and wonderful 400/5.6L. I&#039;m not sure how much market the 400DO has appealed to, the specs are great but the cost prohibitive... birders would rather get the real deal 500/f4 for the extra $400 and skip buying the 1.4XTC that they would have bought for the 400 anyway... and gain a stop and IQ. I would love a 400DO, don&#039;t get me wrong, but I think most wildlife photogs agree that the money it better spent on other options.

A 400/5.6L IS, I&#039;d love one. I got rid of my 400L for many reasons, and one of them was the amount of light needed for sharp shots.</description>

		<description>That&#039;s what I thought too Zac, I just looked up some reviews and the ones I found claim it is weather sealed. The site the-digital-picture.com says &quot;Like many of the newer L-Zooms, the 28-300 IS is weather sealed&quot; and juzaphoto.com writes in his review of it &quot;The built quality is impressive - it is solid as a rock, and it is weather sealed. I won&#039;t hesitate to use this lens even in unfriendly environments and under the rain...&quot; and lensplay.com has it on their &quot;highest level of weather sealing&quot; list.

Maybe they&#039;re all assuming it is because it&#039;s an L lens? Maybe it has some better sealing than the 100-400 but not fully DW-R? It&#039;d be interesting to know. 

Either way though, an updated 100-400 is overdue IMO.</description>

		<description>Yeah should have said ISN&#039;T weather sealed. I use the 100-400 for a compact travel 400, the 2.8 is not something I want to tote around with the rest of my gear it&#039;s just huge, but the push-pull design is a pain, especially with the tightener/lock feature you have to use finger gymnastics to work while shooting. They could have made the lens telescope out from a rotating zoom ring design it would have been MUCH better. ALSO, the push-pull design shoots air into the mirror box if you dont loosen the tightener ring all the way before pulling - not good in a dusty environment - not sure if the 28-300 has that problem or not. IMO the 100-400 really needs an update for the weather sealing at a minimum.</description>

		<description>fair enough.  personally the standard zoom range is not useful enough to me to warrant that much cash.

		<description>Well, I don&#039;t think that is the case. Canon already makes a 24-105 4.0 and I doubt that is stopping anyone from buying a 70-200. I&#039;d certainly not give up the 70-200 if they made a 24-105 2.8, I&#039;d just be selling my 24-70. Like you, I do doubt Canon will make one though. You&#039;d think they would be coming out with new lenses left and right to stay on top but they just sit back and let everyone else come out with lenses I&#039;d like to use. It&#039;s not to the point where I&#039;ll switch, yet! But geeze...friggin Pentax makes a $1400 body with weather sealing that probably bests the 1Ds3, and inexpensive weather sealed 2.8 lenses to match...wish Canon would at least keep up.</description>

		<description>and just for that reason Canon will not make it.
Of course we would all love that perfect lens, but Canon isnt gonna make it when they can sell you 2 lenses instead of 1.

plus for me, id prefer get the lens even wider, maybe about 20 and keep the 70mm :D</description>

		<description>I&#039;d rather keep it 2.8 and extend the tele range out to around 90-105. 70 is a bit short at times and the extra reach would mean not having to switch to the 70-200 as often.</description>

		<description>If this is true then 1d mark iv must be a full frame and canon is trying to compensate for the loss in cropping.
 Since it appears that 1d mark iv is a cropped sensor cam, I believe that this rumor is fake.</description>
