Nikon 16mm f/3.5 AI Lens Cap

[Macro_Cosmos]

Hey yall nerds! I'm one too!

I purchased this fisheye lens some time ago after testing all the other ones that Nikon and third parties offer, I found this one to be the very best! The one downside though is close-focusing capability, but I have my laowa 12mm for that purpose now

Anyone, not going to do a review. My copy did not come with a lens cap unfortunately. Getting a lens cap for that lens is probably like finding a needle in the ocean, or just waiting for another copy to show up... which is also rare. I found some old Elmo metal cap and stuffed flocking in it, and it kind of fits but the flocking goes loose and the sticks onto the tiny hood, which is an annoyance to clean.

Does anyone by a chance have a 3D model made for printing it out (with a 3D printer)? Or may anyone send the precise dimensions, so I can make my own model and print it.

Thanks!
Daniel

Why not just measure your lens on the outside?

Unfortunately, the form factor of the 16/3.5 differs significantly from the more ubiquitous f/2.8 models. Thus their lens caps are not interchangeable.

give me the parts number, maybe I can help you source one

i did find the in-lens filter attachment for the exotic long lenses here but I forgot who was asking and what lens it was. I could've bought it for him

No idea what the part number is! I'd love to know.
Maybe the best would be to get a second copy, I don't mind having another one of these very rare fisheyes.

True that would work too! Probably a bit less precise though, I'll see if I can mod that elmo cap further.

Leica #39213 Slip on lens cap would be my best guess,,,

[Jakov Minić]

I have the cap for the 16/3.5 fish-eye.
The outside diameter is 67mm and the height is 10mm.
I don't see the part number on the lens cap apart from 64K.

I hope it helps...

[Bjørn Rørslett]

Part numbers would be on the internal Nikon dealer catalogues, data sheets,and inventory listings. Never seen them on products sold.

I doubt, however, that any spare parts are left in inventory for such an old lens. However, one sometimes get big surprises ... if the part number emerges I'll have my friendly repair tech run a search for it.

[Bruno Schroder]

While we're at spare parts, if anyone stumble upon the filters, I'm interested. Mine is a battered copy that has lost them all. I'm also interested in a measure of the thickness of the glass, for a DIY solution.

Thanks.

You have the 16mm f/2.8,,, NOT f/3.5 - you can find those filters on eBay,,,

It is the 3.5 I have. I can't find the filters on Ebay unfortunately.

[Bjørn Rørslett]

The f/3.5 has its filters internally. How did you manage to loose them?

[Bruno Schroder]

I bought it like that. The previous owner used it for underwater photography, made all sorts of experiments with filters and lost the original set. It was quite cheap so I bought it anyway.

I've used it on DX for years without too much problems but now, on FX, the corners are really bad and a fix is deeply needed.

[Erik Lund]

OK, so you used the term 'Lost them' a little imprecise then

As I recall the 'filters' on that lens are actually lens 'elements' not flat filter glass,,,
