6-bit coding and the 35 pre-asph lux

[tbarker13]

Just wondering if any users of the 35 pre-asph summilux have had their lens mounts milled for 6-bit coding.
Is there any reason this cannot be done? And would it make much sense to do it? I don't think Leica has a code for this particular lens, so what would you treat it as?

i had that lens milled for coding, but you'll have to send the whole lens in to your favorite "miller". i had good results coding the lens as an asph summilux, but you could also try the summicron codes.

necessary? i understand (from forum posting) that the 35mm focal length is 'borderline'. i found it useful, at minimum cost.

I use the lens uncoded and haven't noticed any problems.

Incidentally, if you can't get hold of a Series VII filter you can use a 49mm filter between the two halves of the lens hood.

I use the lens without coding or filter, but am shooting mostly b/w with this lens. The coding will mainly just put the 35mm into your EXIF info. I doubt you will see any image quality differences. The filter will help with the black magentas if you shoot color.

So it's not possible to remove the mount/flange?
Yeah, I've been using the 49mm filter option. There's a tiny bit of movement in there, but it works fine.
I usually shoot this thing B&W. Really the only reason to do it, I suppose, is for the exif data.

Tim, I have a B+W 486 uv/ir 49mm in my stock hood, it is not a "thin" one, so I reversed it, and to keep it tight, put in a thin rubber band when reassembling the hood.

After some testing, I went to the cron asph rect. hood, as mentioned by RichC in another thread. Works great on the M8 with this lens.

And skintones, and foliage, etc....

Hi Jaapv

Hi Jaapv

Skin tones and foliage, and even cat fur, look purrfect on M8 with no coding and no filter in color.

I'm curious though, do you inadvertently set lens detection on and/or filter on when you've done your testing without filters? Or are you just on your normal use filters rant? 😉

"So it's not possible to remove the mount/flange?"

not possible, according to the local (hannover) leica tech. reinhard who did the rest of the cleaning/adjusting.

good luck

I just exchanged emails with Don Goldberg. Says my particular model has the flange that's quite tough to remove. I can send it to him, and he'll remove it, have it coded, reinstall it, etc.
Just have to decide if that's worth spending $90 on.
