Raynox DCR-150 on NEX-5N
You are doing the right thing. I went for the 250 first and it is a bit frustrating. With increased magnification comes razor thin DOF which makes it hard to take a good shot. I wish I would have started with the 150 first.
Also the universal adapter on my 250 does fit on the 49mm threads but it takes a bit of jiggling and it's tight. I did buy the 43-49 adapter and it's much nicer.
