Hi to all. As said i believe i have a problem with the CM-NF-NEX adaptor made by Commlite. The adaptor is this one.

 

I say "believe" because i am not sure the adapter is faulty or it is simply made this way. Basically the problem is that by attaching my 50mm f1.8 AI-S lens i cannot get past f11. What i mean is that even though i do turn the aperture ring as far as f16 or f22 on the lens the iris does not actually close that much because the little metal thingy that protrudes in the back is prevented from going further from the adapter's thingy that is supposed to move it when a G lens is attached. When trying i have the adapter on number 8  which is the highest available option but it is still not enough to let the iris close beyond f11. To tell the truth i am not even sure that is a clean "11" because i think the iris stops moving before the aperture ring on the lens "clicks" on the 11 so i think it is more like an actual 9 or 10...  

 

As described on the website this adapter is supposed to be compatible with both G and AI (S) Nikkors with and this is the reason i bought in the first place. They even advertize "16 Stops exact aperture adjustment" on their website...

 

Am i doing something wrong??

 

Thanks in advance.

Sadly, I have given up on Sony e to Nikon f adapters.   I tried the cheap ones and they sorta worked without auto focus.   Got the new Vello which was supposed to translate all the electronic data to my A7Rii, but it just won't auto focus my Nikon Zooms.    Too bad.   I sent it back to B and H.   Considering selling all my Nikon gear and staying with Sony.   Sounds like these things work ok with Canon lenses, but not Nikons.

I can only encourage you to do that. I have sold all my Nikon gear and live very happily manual focussing my vintag Contax Zeiss lenses. Never looked back.

I bought the Sony 24-70 f2.8 G and it is better than any Nikon lens I have ever used, including the legendary Nikon 24.70.   Just ordered the Sony 70-300 4.5-5.6.   I hate variable aperture lenses, as a rule, but all I have read say this thing works pretty good.   I mainly shoot outdoors in good light or with strobes.   Nikon and the others better get busy or Sony will run away with the new mirrorless technology.

I use ancient Nikkors, even pre-AI, on a simple Metabones  

adapter. Everything works "as advertised", IOW strictly DIY.

 

The latch and both flanges are excellent. The flanges are

parallel enuf that I cannot detect any focus differences from

area to area of the image ... testing with a 20mm wide open

and using the 10X focus magnifier, and then pixel peeping

the resulting images.  

  

Manual focus works perfectly. All apertures are available.

    • I've been using this lens extensively without any sharpness issues. At long focal lengths, you'll have to factor in the need for a faster shutter speed (< 1/500-ish at 350mm) and other factors like atmospheric distortion, fog/dust haze, etc. All these factors contribute to a deterioration of image quality at longer focal lengths.
    • That's supposed to be a pretty good APS-C lens. Can you try it on a different camera just for the heck of it? Friend? Camera shop? The lens is noted for sharpness, so if you're having as much trouble as you say, you may want to look into a replacement or repair. 
    • Hi everyone, I’m reaching out to the community because I’m facing a persistent image quality issue with my Sony 70–350mm f/4.5–6.3 G OSS lens, and I’d like to know if this is normal behavior or if my copy is defective. Problem description: I’ve extensively compared the 70–350mm G OSS with my Sony 18–135mm f/3.5–5.6 OSS, using a Sony A6700, under controlled conditions: • Identical lighting and background • Same subject and position (LEGO figure, consistent framing) • Tripod or steady support • Manual focus or AF with center point • Same shutter speed (e.g., 1/200s), similar ISO (ISO 4000–6400), RAW + JPEG • OIS turned on (and also tested with OIS off) My observations: • At 135mm, the 70–350mm G OSS delivers softer, flatter images than the 18–135mm, even when stopped down. • At 350mm, the sharpness drops significantly – the center is soft, and textures (like LEGO tiles or fabric) appear blurred or smudged. • Contrast and micro-detail are noticeably inferior across all focal lengths. • The 18–135mm at 135mm (even cropped) retains better edge sharpness and detail definition. • Both JPEG and RAW files confirm the issue – this is not just JPEG processing or noise reduction. Question to the community: • Have others experienced similar softness with the 70–350mm? • Is it possible I have a decentered or optically misaligned copy? • Is there a known issue with OSS introducing softness at long focal lengths? I wanted to love this lens due to the range and portability, but currently it’s unusable for anything where image quality matters. I’m considering returning or sending it for service. Thanks in advance for any feedback or comparison results you can share.
