Hello Joe,

Then again, thank you for your very detailled answer. I couldn't possibly ask for more. It's good to know that the issue "simply" is a matter of perpendicular angle. I naturally assumed that it was part of the answer but I tought that there could have been more to it.

Now I have to do my homeworks. I hope to be able to post news (and fairly improved) shots here rather soon.

If I do buy a wide angle lense (I intend to rent one first), I will necessarily stick to a prime and it will certainly be a genuine Nikon. I don't want to go cheap with lenses.

best regards

Seb
