There is nothing wrong with your Camera.
Do not attempt to adjust the picture.
We are now controlling the image.
We control the horizontal and the vertical.
We can deluge you with a thousand blur circles or expand one single image to crystal clarity and beyond.
We can shape your vision to anything our imagination can conceive.

Using a lens wide-open essentially pushes it to the Design Limit. It's like the Optical Engineers "Outer Limits" for lenses,

Show your pictures shot Wide-Open.

My 50mm/1.2 doesn't have an iris so it's always wide open (unless I add an external aperture)

50mm/1.2 projector lens test shot wide open by Mike Kanssen, on Flickr
It's a Russian projector lens, that cost me under £10, adapted via a steping ring and a helicoid (cross posted on the MFT adapted lenses thread)

Canon LTM 50mm F1.2 and Nikon NIKKOR Z 85mm f/1.8 S. Wide open I prefer the former but the latter is amazing considering that's how the image comes out just by pressing a button without thought or preparation.

A very late KMZ Jupiter-3 5cm F1.5, made in 1956.

This Jupiter-3 is very rare. Most KMZ J-3's have German Glass, German Components, and even lens elements made during WW-2. In 1954 the supply of Schott glass was running low, and the optical formula was recomputed using Russian glass. A Limited run of these lenses was made, this one has the highest serial number I've seen for a KMZ J-3. The rear fixture is different from the earlier lens using German parts. Overall- performance is not as good as the lenses made with German glass, and KMZ turned manufacture over to ZOMZ.

An older shot- with a 1939 Carl Zeiss Jena Sonnar 5cm F1.5, wide-open on the Canon P. Kodacolor 400.

Look how big those RGB pixels are.

This is with one of the very first coated lenses, a 1936 5cm F1.5 Carl Zeiss Jena 5cm F1.5 Sonnar. This is about 2 years before Zeiss started marking their coated lenses with a red "T", which stood for Transparent.

I spent time this weekend learning how to clean, lube, and adjust Jupiter-9 lenses made in Contax mount. I then dedicated a Contax to Leica adapter to it, shimmed the lens an extra 0.167mm to bring it to perfect agreement across the full focus range on my Leica rangefinder. 1.15m to infinity. You just cannot do this on a thread mount J-9 without internal machining of the mechanism.

On the M8, M9, and M Monochrom: use the 75mm framelines for an 85mm lens. Use the insides of the frame.

This is the best J-9 that I've seen, 1955 KMZ. German Glass most likely.

All shots with the Leica M8. I did not use my magnifier for these- usually I do, but managed to nail focus at F2 without a problem. The 270degree focus throw helps.

No aperture available on microscope objectives, so I guess it must have been wide open
Shame I wasn't quite square on...
