Hello everyone! I have a digital rebel and want to buy either a 20D or a Canon 400mm f5.6 prime lens. Of course I will eventually get both, but I've got to decide which one to get first. Can anyone decide for me? Also, how can I prevent my wife from finding out about my purchace(s)?
Since it will be my first white lens, it may be difficult!
In reality, she doesn't really know the price, so I could go to the store and pay half in cash and the rest by credit card, giving the impression that it cost half the price...
Thanks for any advice.
Go for the glass!
