sigma 14mm 2.8

i am considering this lens to add to my collection mainly because it fits into the ikelite dome port 5503.50 that houses my nikkor 60mm and tokina 12-24mm, my question:

is it worth it? necessary? anyone have experience with this lens?

it has an angle view of 114.2 , the tokina 12-24 is 99 to 61 degrees. is it worth to have the extra angle view?

In my opinion it’s mainly about what you like to shot and what your needs more then the specifics port you already have.

I personally will look for something wider since its will give me much more options, so to me its looks better to have one of the fish-eye lens like the Sigma 15 mm or the Nikon 10.5 (my favorite )

That lens costs 900$ (Bh). For that price I would sure get a nikkor 10.5mm (570$) and a sigma 17-70 (390$) for a total of 960$. With your 12-24 and 60 you would end up with a very complete set of lenses...

Hmm - I'd check your figures. The 14mm may span an angle of view of 114.2 degrees on a full frame camera, but I don't see how it can be wider than the 12-24 at the 12mm end. That doesn't make sense.

I think 114.2 is for 35mm format...

I'd seriously look at the 8" dome too. I've got the Canon 10-22mm in the smaller dome and with smaller apertures than f/10 I get blurry edges. I'm about to order the 8" dome as this apparently removes the problem.

as mentioned above - the 14mm is not wider than the 12-24 when used on a DX format camera.

On a DX format camera, it's equivalent to using approx a 21mm lens on a full frame (approx 90 degrees coverage).

Personally I think the 14 is a great lens on a full frame or film camera, but it's an expensive bit of glass to use on a DX format camera given the much more limited angle of view - unless you specifically have a need for this angle of coverage

I second the suggestions above to look at the fisheyes instead if you want extra angle of view (the 15mm will give you around 120 degrees coverage (on a DX camera), the 10.5 around 180
