Nope - not even close Kal - It's not like technology - Lenses have always been pricier for the lower f-stop ones.
To get TRUE wide angle on any DSLR you will need get to 10-14mm range - remember that Digital cameras have a crop factor of 1.5 (some are 1.6) this means you multiply the mm by that number. So when you talk about a traditional camera versus digital, the mm's are not the same. IE 50mm is said to give you the truest picture for portraits. With digital, that's a 35mm lens because you have to multiply by 1.5. With film, it's an actual 50mm lens.
A bit of a science - takes some learning - but for true wide angle - welcome to big money.
