Canon EF 20-400 f/2.8 IO USM IS
Har Har
Canon have just announced the first of a line of ground breaking new optics that actually intensify the light as it passes through the lens. This results in smaller lighter lenses which can have longer zoom ranges but still retain a f2.8 maximum aperture.
This technology has been in development for many years, but achieving a blend of high optical quality with a good amount of light gain and a realistic manufacturing cost has only just become possible with a revolutionary new manufacturing process
Canon are not able to release details of exactly how they make the lenses but, have said that the whole process of manufacturing has to take place in total darkness until the new Starlight Spectra Coating, which is the key to the intensifying of light, has time to develop its light gathering ability.
From what we have gleaned this is the first of a whole new series of IO (Intensifying Optics) Lenses and more lenses are expected in the range later this year.
We were lucky enough this week to be able to handle one of the first lenses into the country and so are able to bring you some details about the new lens. We were unable to shoot any images with the lens as it was pre-production and unfortunately the production models will not be available.

c’mon…you going to ask for a lens do it right…make it at least a 500 or 600/5.6 that way Canon will aim below what we ask for and we might get a 400 or 500mm.

Thanks CR guy. I enjoyed the joke. It speaks volumes for the pros out there who really could use better lenses to match to their high res cameras.

Only if it were tack sharp from corner to corner, had no CAs, and barrel and pincushion distortion were kept to an absolute minimum. :)

They forgot to mention that canon ships this lens with a hot bikini model to put the lens on the camera for you and to massage you while you take pictures.
Plus the lens will fix dry skin, runny nose and fever.
Happy April Fools! The pdf was a nice touch. =)

En français dans le texte : cette optique étant étanche, elle est toute destinée àla photographie de poissons
Might be interresting to take somme underwater pictures …

I think the give away was a 20-400mm lens with f/2.8 IS. Haha, that would cost like $18k if they could make one. haha. Fun story tho.

Wait your saying it’s not a real lens? Crap I just put up my 400mm f/2.8 USM IS, my 70-200mm f/2.8 USM IS and my 24-105mm f/4 USM II IS on ebay so I could pay the $5000 for this lens… Crap I am Screwed.
Happy 4/1

Yay for April Fool’s Day!
If they had announced a 24-70 f/2 I would have been blissfully fooled tho…

I wish I could have that much free time… A bit to obvious but pretty well done.
Why keeping it “white” though…
I’m just surprized that they don’t have a “Direct Print” button on it ;-)

Just a april fools joke. That would be a sweet lens but f/3.5-5.6 not 2.8. The 2.8 would run $12,000+.

Very interesting, hopefully one day this dream can come true.

April 1st, 2009 at 5:55 pm
I actually misread the post, I thought it was 200-400 which is more reasonable range for a straight f2.8…

It seems to be one of the push-pull zoom lenses. 20-400mm must be a loooong push-pull. I wonder whether it comes with an optional pedaling or motorized push-pull mechanism… lol
Reply

April Fool or not, a 20times zoom is just too much
to handle; even from a Canon ‘colourful’ ring lens.
Sincerely,
LMAO with ROFL

Well, when they can add ESW (Electronic Stabilized Wormhole) to the lenses so we can shoot any angle from any point and time in the past I will be impressed.
Reply

The best property is the glowing front lens in lowlight situations. *hihihi*
0,2m @ 400mm would be realy nice. …
The best sentence: I´t might be the last lens you´ll buy.
Next lens will be a 85mm 1:-2 L IO USM
