I'm having difficulty producing good images with a Nikon 75-150 series E lens.
I purchased the lens because it has a good reputation ; it's old and has excessive zoom creep.
While I've never tried the tape trick and I'm not quite sure of the procedure, I agree completely that creep can be a real concern.
I finally had a chance to try out the tape solution, using 3M automotive masking tape since it's easily removed and leaves no residue (and I had some), but it's thin and so I used two layers. It works, I appreciate the brief tutorial and now I like my 75-150 more than ever.It's really easy. I use real gaffer tape as mentioned (it has a cloth-like texture with a bit of friction). I used 1-inch gaffer tape so it wasn't *too* noticeable. I pulled the zoom ring all the way back, and trimmed a piece of tape--using scissors, so I didn't get hanging threads at either end from ripping it--precisely to go from very near the front of the lens to right up to the front edge of the zoom ring. I put the tape on the bottom of the lens barrel at infinity, again so it's not so noticeable--but the barrel does rotate as you focus so at some point it will end up on top; no biggie.
It's not the most elegant of solutions, but it reduced the zoom creep so significantly that the lens was much more pleasantly useable. And it's extraordinarily cheap.
There is a review of the 75-150 here which shows what you *should* expect from it in terms of sharpness and bokeh. And if you want to fix the zoom creep on a more "permanent" basis (the design of the lens, with its felt pad providing the resistance, really means that at some point, the creeping zoom is going to creep back in), Richard Haw has a page describing the disassembly process and potential solutions to the creep.
Yikes if I can offer a perspective on “real” gaffer tape- as someone who spent the last 25 years working as a dp in all manner of production- that stuff is great in the short term, but given any amount of time it absolutely dries out and leaves a horrible residue…
Perhaps the focus issue can be related to the zoom/focus ring slack but the bokeh would still be terrible.
I would like the lens to work for me as it has 52mm filter size so it matches my primes.
My question is, is the lens worth repairing or does this lens just have bad bokeh?

Not only are the images not sharp , the out of focus areas look aweful , being neither in focus or out in other words terrible bokeh.

FWIW, I have a Vivitar 80-200 f 4.5 ( 58mm filters) that produces superior images and pretty good bokeh!
