Which lens next?

[halfmoonray]

Which lens should I get next? It will be the last lens I will be able to buy in a while as I have almost exhausted my camera budget. I shoot all kinds of subject but have been getting in macro more lately. I have been waffling and haven't been able to make up my mind--I've narrowed it to the list below. So your vote counts.

35 f/1.2 L
MP-E 65 f/2.8 macro
135 f/2 L
180 f3.5 macro

Thanks!

None of them. You already have the 100 macro, so if I were in your lucky shoes I would buy the 5D and get the FF effect on your lenses as well as the crop effect you already have.

very interesting and tempting suggestion
