WIDE ANGLE "RETRO-FOCUS" LENS for Nikon D7000 DSLR Camera ??

Is there an "any brand" Wide Angle "Retro-Focus" Lens that would work on a Nikon D7000 DSLR Camera?

For those of you that don't know; a Retro-Focus Lens is one that does not need focusing because the focus is "fixed" due to the fact that it has an incredible depth of field so everything from minimum to infinity is in focus all the time. And, the only thing that can bring the minimum focus closer is the chosen f-stop.

If you know of a lens like that, please give me the brand name, model, mm, and possibly the website where I may check it out.

Any help is appreciated.

Thanks for your time.

I have the rokinon 14mm 2.8 I don't know if that is too wide for you or anything. But regardless it meets the requirements in your post
 
That's not what "retrofocus" means.
It means that the lens design leaves a lot of space behind the lens to clear the DSLR flip up mirror.
All SLR lenses are retrofocal by definition.
This design type was invented by Dr Angenieux in the 1950s

I'm sorry to contradict you, but I believe you are wrong!

I stand corrected. Thanks for clearing that up for me.

The only "retro-focus" lens I have ever owned, was the Angenieux 10mm Retro Focus f1.8 C-Mount Lens, which I used, way back many years ago, on my Beaulieu 16mm Camera in an underwater housing for filming Grey Whales for National Geographic. I therefore, came to the wrong conclusion that "retro" meant non-focusable with a "huge" depth of field.

OK, then WHAT do you call a lens that has incredible depth of field and does NOT focus? There must be a term that applies to it.

Thanks.

Stupid question: why do you want this on a DSLR? A smaller sensor will give you deeper depth of field, hence the usual solution to this problem: a GoPro.

That said, a Tokina 11-16mm ƒ/2.8 stopped down to ƒ/8 and set at the hyperfocal distance should give you more-or-less sharp definition from 1'3" to infinity, according to this tool.
