• UPDATE



    The forum will be moving to a new domain in the near future (canonrumorsforum.com). I have turned off "read-only", but I will only leave the two forum nodes you see active for the time being.

    I don't know at this time how quickly the change will happen, but that will move at a good pace I am sure.

Well there have been many posts about the 11-24 and possible solutions for front mounted filters, hopefully this thread will pull the available solutions together. So far I have seen one set available, from a Vietnamese company, with massive 160mm (?) filters.

Fotodiox had said they were working on a solution and their Wonderpana system is based on a 145mm filter. I have the Wonderpana kit for the 17TS-E so did a little testing with the 11-24 to see if the 145mm filters would cover the 11mm fov, after all it does allow full shift stitching of 17TS-E images that actually give a wider horizontal fov than the 11-24 at 11mm.

Here are the results of resting the 145mm CPL on the built in hood of the 11-24 @ 11mm and 14mm. Looks like any company working with 145/150mm filters is going to have a restricted zoom range.
