II and III are supposed to have exactly same optics but just mechnical / build differences. III was advertised as having improved ergonomics but to me II is the one with better ergonomics (esp. aperture control). There are also some variations within version II as there are many special editions of that and it seems that the focus stick placement is a bit different between various different versions of II. The MTF curves on the data sheets of II and III look identical. Also version I should have same optical design but II and III are stated to improve

Juha,
I wanted to express my gratitude for providing such extensive information. Your collection of MS-Optics samples is undoubtedly the most comprehensive resource available. It's unfortunate that this lens is currently out of stock everywhere, but I'll be sure to monitor its availability closely. Personally, I wouldn't mind if the minimum focusing distance (MFD) were 0.7m or even longer, as I intend to use it exclusively on the M camera.

Thank you once again for your valuable insights.

Cosmetically I think this lens looks great apart from the way too much text on it. It seems every surface has something written on it!

Clean it up by:

1. Get rid of the filter size description
2. Get rid of the 'xslim pro M' text.
3. Just have the serial number. No need for "No." and "BP"
4. Get rid of "Brightin Star"... ok, at least make the font match the rest.
5. Pick one set of focus distance scales.

Those are excellent suggestions, but I doubt they will be implemented. Take, for example, the Brightin Star 50mm F0.95 lens, which features their logo/name engraved on the built-in hood!

On another note, all the mentioned items could potentially be made less distracting by applying some acetone to make them black in color.

It's crazy how that logo ruins the look of the lens. it is actually a handsome design.

I'm confused. Is that a mounting index on the left side?

That most probably is the Nikon mount version.

A review of this lens in Chinese. She also compared the lens against Leica 28mm 2.8. English subtitle is available, probably just google auto translate.

I enjoyed reading this impartial review (Auto translate). Here are the key points I took away from it:

• The lens has a filter thread size of 25.5mm, and while filters for this size do exist, they may be challenging to find.
• The filter cap screws into the filter thread. (instead of clip-on)
• There is no threaded hood included.
• While the lens resembles the MS Optics APOQUALIA 28/2, the reviewer prefers that Chinese manufacturers would develop their own style. But when you take a closer look at their optical designs, they actually look pretty different.
• The lens is very thin at only 9.9mm in thickness. The Leica 28 Elmarit is 18mm in comparison.
• Focuses down to 0.7m with rangefinder coupling on the M10 and M11 bodies.
• Sharpness is good at the center when wide open, but corners are slightly blurry. The cause could be decentering, astigmatism, field curvature, etc.. (The reviewer didn't specified)
• Axial chromatic aberration is noticeable at f/2.8.
• Rangefinder coupling doesn't work on M9 bodies from 0.7 to 1m, although this might be specific to the reviewer's copy.
• Corner sharpness improves when stopped down to f/5.6 and f/8, but it's still not optimal.
• Compared to the Leica 28/2.8 Elmarit (v1), the latter is slightly sharper at the center and significantly sharper at the corners. (Somewhat expected results)
• The Brightin Star lens has a cooler color temperature compared to the Leica.
• Some barrel distortion (+4 adjustment in LR to fix it)
• The focusing ring is smooth, and the lens has an overall great appearance.
• The packaging is nicely done, but it lacks consistency in design and style compared to previous Brightin Star lenses.

Looks to have a bit of barrel distortion. But how can I complain? I use the Lomo Minitar which has pincouch distortion.
After I get my Sharpie out to cover up most of the text, this lens will look great on my BP MP w .58 finder.

Actually Fred what was that brand of permanent marker that someone had mentioned for 6bit coding? That would work better.

Couldn't reach my contact there, hope he is simply on vacation or they are just looking for a new VPN.

In their own advertisement, the announced date was 05/31/2023, but I just realized that it goes until 06/20/2023.
