Donoreo, I knew it was a regular on here, I just couldn't remember who. Do you have any links to your photo challenge?
Silverthorn, try not to think of your lenses as landscape, wildlife, portrait etc. You can take all of these with any of your lenses, it's just a matter of the effect that you are trying to achieve. There's no reason why you can't take a close up with a wide angle lens (which you might call a landscape lens) like this at 16mm (

Good luck with your challenge, I look forward to seeing the results. I think once you tie yourself to the 50mm for a while, you really are going to enjoy it. BTW - this is a photo I took with my 50mm
