50/1.1 MS-Sonnetar: the next cult lens?

Well, I got mine and it brings up the 28/90 framelines on my M6. So I guess it's going back to Japan. I could theoretically file down the bayonet, correct? But I'm leery of doing so. Any bright ideas?
 
Actually, on second glance, it looks like the little tab just gets squeezed into the big one. See the photos I sent you.

Framelines: When I got mine, the lens would bring up the wrong lines on my M6, but not my M7, M3 or m240. No idea why, but since it worked fine on the later three I chalked it up to M6.

So I rarely use it on the M240, mostly because it has a pretty good ISO, so I don't feel the need to use such a quick lens on it. When I have used it, it's been in some very low light and getting focus right can be really tricking (and just as tricky with any lens) as the light is so low I can't really see what I want to focus on. Below is a good example, I couldn't really make out enough details on the cat's face to use it as focus point and mainly used his right ear line to set focus on. These are all at 1.1, 2000iso and 1/30th (so not as sharp as they could be).

Or perhaps this little tab was supposed to have been snapped off?

Is that a factory installed hair on the back of your lens there? 😀

Miyazaki-san really needs to outsource assembly of his lenses to a proper factory IMO. Assembling them on his bench in his basement one at a time just doesn't cut it in terms of maintaining a decent level of quality control.
 
Mine is finicky on the frame lines, but if I hit the frame selector once (m9) the 50 lines pop up. Another quirk, but I don't care. It's a tiny 1.1 sonnar and they don't grow on trees, at least in Idaho 🙂

Yes, I think you're right. And I think jonmanjiro is right about what's going on here: Miyazaki-San is making things easier for himself with this engineering hack: for the 28mm and 24mm Perars, leave the tab as it is; for the Sonnetar, bend it over; and for the 35mm Perar, snap it off. And he forgot to bend it over. Anyway, thank you for the pics, Dante!

I wrote to JE and Dirk is inviting me to do this myself. He asked whether the 50/75 lines come up on the way to the lens clicking home, and they do; I believe that means that yes, squeeze it closer, not bend it farther away? Anyway, I'll do this as soon as he tells me to go for it.

Actually I think it is! Nobody in my family has hair like that. Maybe the lens is having an affair?
 
Also, shooting with the lens last night: I don't think I've ever used a lens that handles so bizarrely. At first I thought, well crap, I can't do this. But then I got the hang of it, sorta. I'm finding myself gripping the front ring rather than using the tab, which of course is in a very weird place. Highly eccentric.

This is also the case with my lens. On the M9, it will bring up the 50mm frame lines about halfway when first mounted, then the slightest nudge on the frame selector lever gives me the full 50mm lines. It's never really bothered me, though I imagine it would be more annoying if there weren't a frame selector there.

The good sony E-mount lenses are famous for decentered copies.

To me it's more a matter of the rear mount design, which is unusual. The only lens I own with a screw on rear lens cap LOL
