    Just got a 5.0cm Nikkor f1.4 in S mountban us wondering what type of filter I should use. Read somewhere that the thread is different than the current filters

    Thanks

    I use standard 43mm filters, no difference that I've ever seen. I have picked up many of these over the past 10 years...

    I just bought a "lot" of 43mm filters, all fit. The 135/3.5 also uses 43mm filters.

    Different story with this 50 when mounted on my M body. The focusing was quite off when used with the Amadeo adapter. I think my adapter was for a Contax lens and not a Nikon S. Guess the only way to fix this is to get another adapter that is for a Nikon S? Is there any other way I can adjust the focus of this lens?

    The optics module is held into place by a retaining ring, held in from the back. Easily unscrews with a rubber cork. A shim is used to control the stand-off distance. Determine how far off the focus is from current, use a ruler at a known distance- like 1m. Measure the error, back-focus: thicker shim; front-focus-reduce the shim. I use copper wire when i don;t have the correct shim.

    Unlike the Sonnar, this one I am not too happy with. Even with EVF, I am not able to get a good shot. I am finding the image to be too soft. Even focusing on the EVF is not easy for me. Might just need some practice? Got too spoiled with the Summilux ASPH

    I have a hard time focusing an F1.4 lens with the EVF-2 on the Olympus, and that's the same finder for the M240.

    Mine is spot-on with the rangefinder and Amedeo adapter AFTER I adjusted the Shim. It is spot on.

    Wide-Open on the M8,

    Brian,

    Thanks for the info. You gave me a little hope for this lens. I took the lens apart. There is one shim inside. I took it out and when I did a quick comparison between RF and EVF, it looks pretty close. I will try to do some shot maybe tomorrow.

    Regards
    Vince

    If focus is on the eyes, it is back-focusing. Try a ruler shot, see how far off it is- we can compute the required shim.

    Forgot to say that I did crop the image. The camera was mounted on a tripod and use the selftimer to trigger the shutter.
