New lens: Canon EF 20-400mm f/2.8 IO USM IS
Hi, guys. I haven’t wrote anything for more than a month, and I apologize for that. I had some personal things to take care of. Now hopefully I will continue writing new posts.
I would like to let you know that Canon has just announced a line of some amazing new lenses with optics that intensify the light as it passes through. This technology has been in development for many years, and because of a new revolutionary manufacturing process, the production of this high quality optics it possible at affordable prices.
Canon can’t release details of exactly how they make the lenses (for obvious reasons) but, they have said that the process of manufacturing has to take place in complete darkness until the new Starlight Spectra Coating, which is the key to the intensifying of light, has time to develop its light gathering ability.
So Canon has started the line of new lenses with this 20-400mm f/2.8 IO (Intensifying Optics) IS USM, and from what I understand they will release more lenses with this special ability.
As a side note, I have read somewhere, forgot where, a rumor that Canon stops producing the famous 70-200mm f/2.8. Now i can understand why, maybe because they are going to release a new version of 70-200mm with IO.
So the estimated price is somewhere around 4100$ (3100€) and the release date it’s sometime in autumn 2009. Also here’s a list of key features:
- Aspherical optics used on all elements except for front SSC coated element
- Pro quality optics on a par with L series lens quality
- Robust design with build quality equivalent to L series lenses
- Image intensifying optics used in front element of lens
- Lens feature full time mechanical manual focusing
- Fully flocked throughout to prevent internal reflections
- One touch design for speed of zooming
- Optical image stabiliser with 6 stop correction for handshake
- Lens supplied with removable tripod mount
