New EF 70-300 f/4-5.6 IS?
I've received an email saying Canon will be replacing the 70-300 f/4-5.6 IS with a new version.

The current version was launched in 2005 and has been a good seller for Canon.

I have heard stories from various retailers about the lens being backordered for a while now.

I'm going to say the likelihood of this being replaced is low, unless I hear from better sources.

These are still easy to get from Canon, I do not see a replacement.

  1. so if canon typically releases 2-3 lenses per announcement and one of them is highly likely to be the 24-70 2.8 IS and the ef-s one is the 60mm 2.8 IS, am I pushing my luck for a possible third L lenses to be released? 14-24?

    EF 70-300 will add ring USM updated IS and a new optical formula possibly fluorite element. Aperture will remain the same although would be nice if it where a constant f/4.

  3. the difference though is that the oly lenses are really double – so they are actually much SMALLER. They are never going on a full frame while canons long lenses are designed for FF.

    The 250 2.8 that you mention is a 500 2.8 in real world – Imagine the size of the white lens canon would make to reproduce that….

  4. Constant f/4 would be nice but is not going to happen as it would rival the 70-200 f/4 L IS.

    But even with the same optics as the current 70-300 but with ring-USM and a non-rotating front-element, this lens would still be a winner.
