Full frame Canon 5D & Sigma 18-200 non OS lens.
May I ask for a quick bit of help here, please, ladies & gents.
Yesterday, I sold a rarely used Sigma 18-200 mm non OS lens to a pal of mine whom is lucky enough to have a Canon 5D.
My pal called this morning and it seems that the 5D is too advanced for the lens - far too much chromatic abboration at the extreme wide and at the longer end of the telephoto lens.
Now, the question is will the entry level Canon 18-55 mm series I IS work on the Canon 5D?
A second question while I am at it - anyone have any comments about the type of week long photography courses you can take in, for example, London? They usually cost between £600 & £700.
Thanks and greetings from Cork.
