The above pictures were taken somewhere in between the MFD and infinity. That being said, with the 150 on the lens, there is practically no difference between "close" and "infinity".

I've found that infinity usually gives the best results if I'm having trouble with vignetting. The long end F11 shots look nice and sharp. If you can't get rid of the vignetting with the settings, you could crop that one.

Yeah, the corners end up looking the same regardless of focal distance (close v. infinity), which as I mentioned before is a very tight range of only a couple inches with the Raynox 150 mounted.

I suppose you could use the 50-135 @ 135mm in a pinch with the Raynox and crop a little, but in general there are far better options. From what I've read, the Raynox works very well on the 55-300 @ 300mm. Sticking it on a 50mm prime would probably produce pretty good results as well, although with a substantially smaller working distance. FWIW, I tried the Raynox on the 77/1.8 and it's pretty impressive.

The Raynox 250 works better on short focal lengths (under about 135mm), but more likely to vignette and a shorter subject distance than the 150.

Here are four quick shots I just took at 50mm and 135mm at f/2.8 and f/11.

So 135mm at 2.8 produce no vignetting or at least very minimal.....

Yup, just double checked it shooting againt a white wall. At 135mm and f/2.8, there is still a little vignetting at the corners. It's not as distinct as the other settings I tested, but the corners and even the left and right edges are darker than they should be. Plus, if you were using this as a macro, you'd more likely be closer to f/11 than f/2.8 where the corners are a little worse.

That said, if all you happen to have with you was a 50-135 and Raynox 150, and were in a pinch, you could certainly use it to get close. You just might have to do some cropping after to get rid of the corners.
