I would suggest you create a second lens category for the discussion of third-party lenses with a Canon mount. It's not clear right now for example if I should discuss my Tamron 150-600 G2 in the Canon lens category or somewhere else.
Dave, You can post it to the Canon Lens section of our forums. I'd rather not create another section for almost the same subject, it will make it harder to find topics in my opinion if we have too many forums.
Thanks for all your help, but one more question if you dont mind. Is there anyway at all to get the third party camera apps to work or would this involve me changing the manifest too.
