I have some P6 lenses that currently have adapters for Sony A and I'm wondering if I should purchase an A/AF to NEX adapter or just find a P6 to NEX. The former would be cheaper and easier when switching from SLR to NEX and back.

Following my oops moment, I saw that same adapter, as opposed to this one. Thus I'd say the analysis in your first post is probably correct (if you don't need that strong-looking tripod mount).

I don't like the idea of double adapter, but in this case it is easier (hopefully) and cheaper. And I go with that seller because they sell from here in the US, so I expect to have it sooner.

That looks like the one I bought. It turned out to be a little too short, so I put a shim (cut from a yoghurt pot lid!) under the mount plate, to restore the close-up focus. It still focuses at infinity. The other issue I had with it was that the projection from the aperture actuator was too long to allow some lenses to fit. It turned out the projection is a screw, and can be adjusted. |

That's exactly what I found: please see my post at the bottom of the previous page. Strictly speaking, in my case the adapter was 0.2mm too short. It may sound as very little but it can have quite pronounced effect on the focusing. Still, as I wrote, it is better this way around because you are able to focus on infinity loosing some short distance focusing. Besides, as you noted it is relatively easy to fix the problem adding a shim. |

Thank you. I prefer going past infinity because otherwise I do not trust that they would have it stop perfectly and not just a tad short. The only way you can know that you hit infinity is to go past and come back. I notice on some of my lenses that a very tiny amount of turn can make a difference. What impact does .2mm have on short focus? Only to change MFD, right? By how much? |

It would be dependent on the lens, but, with the Minolta 100mm 2.8 macro, I seem to remember about 18 inches, which is considerable. |

Well, I have not checked the short end carefully but depending on the "purpose" of the lens it could be quite significant: I think that macro lenses would be affected more ... |

I've just checked my Tammy 90/2.8 mounted on this Minolta AF - NEX adapter which seems to be too short and it turned out that ... it works OK, i.e. the shortest focusing distance is about 29cm and about the same I measured on NEX. So 0.2mm seems to be insignificant

Hi all, there's been a lot of buzz about the Speedbooster and now the Chinese copy's offered in some new mounts. I recently acquired the Lens Turbo MD-NEX. Haven't had much time to play with it yet, but I am hoping this weekend I can get some sample images posted. My initial impression is that similar to a normal teleconverter, it will emphasize any defects in the lens, so if you saw a slight halo at f/1.4 with the lens normally, it will be worse when used with this adapter. Most of the lenses I've tried that are below f/2.8 need to be stopped down and are almost unusable wide open. Most of my MD lenses have a slight noticeable haloing with a non-optical adapter on my NEX's, so I don't know that its the adapters fault necessarily. Anyhow, you'll see what I mean when I get some samples posted. Not to say its a bad adapter - it actually is quite interesting to use, but will have to work within its limits.
In the meantime, here's a teaser pic on my 5n: ![]() |

Thanks Greg; that was the report I was waiting for as I'd been considering the MD adaptor and you've tackled the issue I was concerned about.
But I'd want it to work with lenses wide open and specifically the 58mm f1.2, so it's useful to know that it won't help in that case ![]() P.S. Looks shorter than the normal MD adaptors which would be nice: do you have a normal one to compare the lengths? |

This may be old news for you, but I've found that my NEX-5N with CA control turned on does an amazing job of removing the halo and virtually all CA. This may be a compromise for those that only use raw. I have a fast lens that was unusable at full aperture in all but dimly lighted applications, but is now fully usable and even tack sharp at fully open.
