I don't know how I could have done the attached photograph with an uncoated lens, or one that is poorly corrected.
Don't let your equipment in the form of lenses hinder you from taking great pictures. Work with what you have, but - you must know your lenses intimately to eke the best out of them. Explore your lenses at the wide apertures, print the results, look at the pictures and start to decide how you want to use what you see.
To me, to create a three dimensional effect in the photograph, you must use objects in front of the lens that are near and those that are far away - and their relationship - well, in order to create an effect of the subject standing out from the background. Distance to your subject, lens opening, and focal length plays in here. But lighting becomes important as well. To separate tonal values of the subject from those of the background becomes important.
I attached a picture here, which was very difficult to do (for me). It's from a wedding, and I was asked to shoot candids and portraits of people there. It was a casual setting in a stunningly beautiful area of Sonoma County, California. I wanted to emphasize the mood of the place AND make some decent pictures of people. So I decided to use the radiance of the background to emphasize the beautiful light, while I let these two people be the 'calm' part of the picture. The skin tones are what's smooth here, and the background is where the crazy texture exists, AND there is a big brightness difference between them and the background, hopefully separating them enough from the backdrop to stand out.
(I could have given the negative a half stop more exposure or so, but it was a compromise since there were a lot of other types of exposures on the same roll of film).
Like I said earlier, I don't think a single coated or uncoated, uncorrected lens could have handled this type of exposure. So if you decide to try your hand at older lenses, you have to watch, very carefully, your lighting, or you will have flare all over the place. You may end up limiting your shooting options that way, unless you're prepared to carry all sorts of lenses.
This is shot with a very old Hasselblad 500C and a normal Planar lens. Not very exotic, but it works.
I should add that the lens can be a very important piece of the puzzle, so there's nothing wrong with owning a lot of different lenses. It can be enriching, I believe. As long as the lens fits in with your vision and presentation, go for it. But you may want to think long and hard about whether you actually need it or not. I guess I just want to encourage highly critical thinking.
