From an amateur observer.... could Canon up the aperture to say f/2.5 with a 82mm filter size with the other "small" mods (IS/coatings etc) and then significantly lead the market and justify an increased price?neuroanatomist said:kphoto99 said:neuroanatomist said:Maiaibing said:You need to go into optical engineering.

No need to artificially limit it to 2.8 at 70mm when it could do 1.4 at 70, 2 at 135 and 2.8 at 200.
For those that like constant aperture you still have 2.8 everywhere, but for those that like more versility you get faster lens at the wider end.

Maybe the great Neuro could explain why when Canon is designing a new lens with an entrance pupil of 71mm it can not be a 1.4 aperture at 70mm (70/71=1 and 200/71=2.8)?
It is not like Canon does not know how to do variable aperture lenses.
Sure, Canon knows how to do variable aperture lenses. The 100-400 needs the same 71mm entrance pupil as a 200/2.8, and 100/71 = 1.4. Why the heck did those dumb optical engineers at Canon make it a pathetic f/4.5 at the wide end, when clearly it can be f/2 or even f/1.8? Same with the 70-300L, limiting its variable aperture to a pathetic f/4 at the wide end when clearly since 70/53.5 = 1.3 it should be f/1.4 or at worst f/1.8?
What could Canon know that you don't? Oh yeah, they know how to design lenses. :

Or, in typical Canon fashion, they will jack up the price to $2800j-nord said:Nikons got a new 70-200 for $2,800. In typical Canon fashion they are going produce a new lens that outperforms and under cuts Nikons latest and greatest lens.

Everyone's a comedian.
We presently have a staple tool of a 50mm f/1.4 that dates back to the earliest parts of the Clinton administration and here goes Canon, updating its f/2.8 zooms every 8-10 years with the regularity of Old Faithful.
Give me a damn sharp 50 prime with modern USM that is smaller than a pickle jar. Take my money.

This is pretty much what I thought as well when reading the rumor. There is no need for an update with this lens (70-200 L f2.8 IS II). When you use this lens and something is wrong with your photo: it was you!But it also sells in strong numbers. It could be that the manufacturing tools are now requiring replacement or ongoing maintenance to keep going, so a replacement lens could be just as cost effective as maintaining the current design with some newer technology in the areas of IS and some optical improvement opportunities. It isn't necessarily about optical performance.

No, but it should support wi-fi so users could see the data on their smartphones.

It could but it would increase size and weight. Plus you would be inclined to have a milkshake instead of taking a nice photo ;D ;D ;Darthurbikemad said:tron said:And GPS in case camera does not have one ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;DAntono Refa said:Maximilian said:Does it have to be a swivel screen? ;DMaiaibing said:arthurbikemad said:LCD screen,

Am I missing something, is the LCD display on lenses not something that's happening? i.e EF 70-300??? It can have a friken milkshake machine on it for all I care..
