If you can fit a filter to the front of your lens, you could buy a wide angle adapter like a 0.5, with the screw size that fits your filter screw.
But the wide angle front lenses, were designed for compact camera's and video camera's And although the 18 mm could become like 12 mm, but you will introduce colour fringing, distortion and more , that can't be corrected in normal programs like Lightroom.
I used a wide angle 0,5x (52mm) Hama and a tele 1,5x from cannon, on my video and later on my canon powershot G9, to find I was looking for a DSLR. I never was quiet pleased with the results.
And yes, sometimes you can't go farther back, but then I shoot 2 or 3 pictures.
Now I use a 12 - 24 on my Nikon DSLR. Now I get the pictures I want in a quality that fits.
My 0,5 and 1,5 are somewhere in a box. I payed the same (new) for both as for my Sigma 12-24. With the sigma I do have fun.
I'm afraid this will not work.
The filter size from the Nikon is 67 mm. and your vivvitar had a 52 mm tread. The step down convertor from 67 to 52 will block to much to use the wide-angle convertor.
I think you still will see a wider part in the centre of the frame, but in the end, the vignetting that takes place, will leave you with only a part of the picture to use. What stays will be smaller than what you pick up with the lens in the 18 mm setting.
Just try what you see, when you just hold the vivitar in front of the lens and shoot a picture. Take care you don't scratch the front lens of your 18-135. put a cheap UV filter, when you want to test.
See you only have a circular picture with this test.
I have a 12-24 lens and only use it once a year, so if you don't have a special purpose for a wide angle, don't bother buying one.
If by a "normal" lens, you mean a 35mm or 50mm fixed focal length - often called "prime" lens, that is to be expected. The additional and internal rotating optical elements all contribute to loss of clarity, color loss, and increased chromatic aberration that starts to become noticeable when compared to use of a prime lens. It's a trade off; less number of lenses to carry and lower cost when using wide angle zoom lenses as opposed to a prime lens for even just a few of the focal lengths offered by the wide angle zoom types.
You can minimize the unwanted effects by staying away from both the extreme wide angle and zoom focal lengths as well as the widest aperture settings. If you can stay 2 or 3 stops smaller from wide open, you can limit these destractions from your pictures. This is recommended advice for nearly every lens: Keep away from the extremes.
No. It's an optical fault and is either a manufacturing defect or a design flaw.
Such problems are VERY common with ALL no-name brand supplementary screw-on lenses and not entirely uncommon even on branded similar models costing vastly more and intended for a specific make and model of camera.
Supplementary lenses are simply a get-you-by compromise, they will never be anywhere near as good in terms of image quality as a lens designed to be a wide angler or telephoto from the outset but will allow you to capture image which may otherwise be unattainable without a lot of additional expense and equipment.
It's a specialised lens used only for large format cameras used by professionals where 120mm is considered to be a very wide angle lens.
It's not usable on any Nikon SLR's nor on any medium format models.
Sold privately, and in perfect condition the lens is worth around £250-£350 depending on how much the buyer wants it. From a retailer the price is around £500 (these are UK prices, in the USA they'll be around 25-30% lower).
