I picked up my Lensbaby Composer at the weekend and immediately stuck it on the D3 for a couple of test photos in the back garden.
Initial impression is that this is a well built lens that is capable of surprisingly sharp images. It is extremely fun to use and while it will take a bit of getting used to I think that I find frequent opportunities to use it in the coming months.
The photo below is a quick shot a f/2 lifted straight from the camera.
I will work on a more detailed review once I have had a better chance to use the lens...
