After waiting a very long time, here comes the official announcement of the new Canon 200-400mm tele zoom with integrated 1.4x focal multiplier. Everything has already been told and written (you’ll find below a list of announcement papers in other blogs), except the price: A whooping 11769 US Dollar! Even a little higher than what [...]

Here is one big lens who knows how to make people wait: The all-new, all-innovative super-tele-zoom lens from Canon, the EF 200-400 f/4L IS 1.4x. It’s a lens which was pre-announced by Canon more than a year ago (for the first time). Since then, the rumors extended beyond reason. The lens was seen several times [...]

It’s hard to be sure of the details on this new lens from Sigma, since they announced that there is a delay (it will not be available this month – in March 2013). The only useful thing I would like to point to the significant items in the spec list: Dust-proof and splash-proof construction High [...]

I should never exaggerate the importance of patent publishing (some of them are only a way to make sure nobody can re-use the same idea when invented independently), but it is interesting to notice that Canon published a patent for an architecture targeting a 100-400mm f/4-5.6 tele-zoom which could well become the next replacement for [...]

We no longer can say that this is a delay. Canon has been announcing so many of these up to now. Recently, they updated the list of availability for the future pro tele-lenses: EF 300mm f/2.8L IS II USM at $6,599, late August 2011 EF 400mm f/2.8L IS II USM at $10,499, late August 2011 [...]

This may be something that many people missed, but when Egami (a Japanese blog) produced a patent from Canon for a 300mm f/4, the important part may not have been the possible upcoming tele-lens but the technology used in the lens to reach a better Image Stabilization (IS). Up to now, Canon and Nikon have [...]

After a renewal of the 300mm and 400mm offering of Canon in the L series of pro lenses, nobody will be surprised to see Canon announce that there will be new versions of the 500mm f/4 and 600mm f/4 lenses. Obviously reserved to the pros with deep pockets (for wildlife or sports photography), these lenses [...]

Now, if you want something weird, look at the announcement by Canon today: They started the development of a tele-zoom lens that you did not see anywhere else. Maybe Canon was inspired by the success (and the quality) of the Nikon 200-400mm f/4G ED AF-S VR II Nikkor. But obviously, Canon wanted to bring some [...]
