Widest wide angle photography lens

[JJ!]

What is the name of the widest wide angle photography lens?

This is the question that my friend is trying to answer in a competition.

All I can think of is the 10-22 Canon and 10-20 Sigma, but they are both as wide as each other!

I'm guessing you cant include fisheyes, as the question specifies 'wide angle photography lens'.

Depends if you include crop factor. Just looking now. Old lenses as well?

 

[JJ!]

The question does not specify if it has to be new or old, and crop factor does not have to be taken in to consideration, so I guess anything goes!

Well there are quite a few lenses like this one:

And they're wider than a 10mm on a 1.6 crop. I don't know tbh, sounds like some sort of trick question. Who's he answering it for?

Ohh good find that Nikon one! The question was in the english garden to win a days shooting with Sarah Howard. Not my cuppa, but thought it was an interesting and misleading question!!

I lol'd

8mm sigma? or is fisheye not included?

 

[Feirny]

Sigma do a 4.5mm circular fisheye.

Does anyone want to buy a Lotus?

Some of the rare lenses can fetch silly money. A mate of mine found an old nikon lens in some random shop for £400. He knew what it was but the shop owner didn't as it sells on eBay for anything up to £4000!!

Did your mate buy it?

 

[Andy.]

Like a shot! It's a 58mm f1,2 NOCT Nikkor. He has had offers over 2k for it.

widest rectiliner lens is the sigma 12-24mm with a FOV of 122 degrees, a fisheye can be 180 degrees
