Manufacturing Error - 28 cron labeled as 35

On the photo both lenses seem to have the same size, but the length of a 35mm Summicron is 34.5mm while the real 28mm Summicron measures 40.8mm. 

Did you try the 28mm - is the focus exact, does it activate the frames for 28mm, does the  6-bit code differ from the 35mm? Does it really cover the field of view of 28mm?

I would certainly check this. It is very possible that it just has the wrong engraving on the bezel.

I think the height difference isn’t visible because the hoods are on both. It is a 28 FOV. Focusing scale doesn’t work because it has the 35 distances marks. The coding is for a 35 cron as well. Not sure on frame lines because I only have the SL2. Basically the focusing mechanism is the 35 cron and the optics are the 28 cron.

My my, how you "lottery winners" backed down when he offered the lens for sale.

Gotta ask. Portugal or Germany?

I recently purchased a new 28 cron and it arrived sealed however the barrel of the lens is stamped 35mm and the top is stamped 28mm. The lens is actually a 28 Cron. Should I exchange for a new one or is there any collectors value with this type of defect?

If it's just a wrong part, probably not worth keeping. It'll only confuse the hell out of it even just picking the right lens to use. It'll worth a fortune if only the focal length that's wrong.

Funny how they are able to go through all assembly process without anyone picking up the wrong barrel - and they are even interchangeable.

Bah, be done with it - throw it in the trash and buy another.

I once had a 600mm f/4 Nikkor that was marked as an 18mm f/2.8 - when I sold it at auction, I actually ended up owing money.  😳

Awesome.

If it were me, though, back to Wetzlar.  I'd be too paranoid about the lens not performing at the level I paid for.

[Noctiluchs]

Is there any chance that it was manufactured on the 1st of April?  😆

What about the box? Is it the bow of a 28 or 35? Serials match ? 

Box shows 28 cron. All serials match on box, lens and inspection card.

That's pretty bizarre.  I'd exchange it for a proper lens.

I was on the phone with Schouten this morning to finish a transcaction. Out of curiosity, I asked him quickly if such things could be worth any money. He said that it's happened before, and you could maybe sell it 5-10% more than what you paid for because "some people are crazy" but that in theory it's not really worth anything and you should better return it.

He mentionned to me that he sold last week an 8 element with no box for 6K because the serial number ended with 4444 and the buyer was obsessed with the number 4. People are crazy?

Yeah, I didn’t want to mess with it. Just dropped it off for an exchange.

Apparently the number 4 is a thing with some who are afflicted with Obsessive Compulsive Disorder.

Maybe he's in room 4 of the mental hospital too

Also always pays to check various cultural numerologies - 4, 4 times (i.e. 4444) means "physically active" in China - and the word "God" supposedly appears 4444 times in the King James Bible (according to jewish gematria), and 4444 has other meanings in other cultures.

Lens "numerology" won me $90 in the Indiana Lottery once - I had  16, 20, 28, 35, 85 focal lengths, from which I picked 5/8/16/20/28/35 on the ticket - the bold numbers were drawn.

Thanks for the Input. I am on the fence on what to do. The lens is coded as a 35 and also the focus scale is of course also off. I guess I could keep and buy another but worry it might not actually be collectible. 

Do not keep it. I'll take it off your hands for your cost.

Oh well, too late. 😢

You'd think the buyer would want a Mk4 ...
