I consider myself a lens noob but not too bad understanding how to get the right amount of light, exposure etc to make an image look decent.
I've a long way to go but tonight i took what i thought was a bloody good image... ok, feel free to judge me .... blah blah LOL
^^ no idea if that will work
What i used was .
Canon kiss x4 (550D) with the standard suppled EF-S 55-250mm IS.
I really wished i had something more powerful but i'm really not in a position to buy new lenses at this stage but did consider a lens doubler (or teleconvertor). New lenses came later.
Now i read pretty much EVERYWHERE you can't use them (the offical Canon one that is) with the EF-S IS lens and you need to use the L series lens, BUT ... if i use a Kenko Pro 300 DG then they have a much wider acceptance for lens.
I wanted to double check this info and found conflicts everywhere.
From here that actually sells the exact two lens as a kit http://www.digitalrev.com/en/canon-ef-s ... -4329.html
but then this here

see the heading "why choose kenko over canon" that seems to clarify you can't.
This has taken me all night and it's 2:30am so i wonder if anyone knows if what i want can be done with this lens but maybe with one of the other brands like Sigma or Tokina etc.
Lastly, if i can't, can someone explain why?
