Well, the commentary on this topic certainly set the day off to a good start.
Don't know what camera you have but KEH has quite a few Tamron, Sigma and, yes, Quantaray lenses in the zoom range you mention for under $100. Do a search there in "shop by top mounts" and set the sort to Price Ascending. I think you'll find a replacement lens at a price point that will make it uneconomical to attempt to get yours fixed and you'll have a bit of a warranty. I had a Sigma 28-200 of film era vintage lock up at 28 mm and they simply refunded my money. As I recall I paid less than $40 for it and they didn't consider it worthy of returning the lens.
Good luck

It is made by Sigma. Older Sigma lenses have plastic focus drive gears, which are prone to stripping. It's a common problem on Minolta and Sony versions due to the power of the drive motor in the camera. I am not sure if other cameras have the same issue, but age is not always kind to plastic gears.

Why do I keep reading the word lens spelled lense?

Why does it matter if you know what their talking about? One hundred years from now after we are all dead no one will remember anyway.

Quantaray was the private brand of Ritz Cameras, of blessed memory. Good luck with repairs.

And since Ritz changed ownership they don't have the Quantaray brand any more. I really want to know which camera the OP used the lens with and did the lens ever work with this camera before?

I would 1) ignore the BS and 2) contact a repair service. I don't think it is a problem that can be diagnosed with out a hands on look at the lens and camera.

Because English, as every language, is in continual flux of usage and because there always have been, as there always will be, some words in contention for “...the approved, and universally accepted spelling”. “Lens” and “lense” are representative of many nonce examples contending for “official” orthographic preference. Preference by whom? The Oxford English Dictionary, for one.

Which of the several contending authoritative standards is the ultimate arbiter of spelling? Beats me, but, with sufficient time, Norma Loquendi (who captured the heart of William Safire) has often proven reliable.

You can replace the lens easier/cheaper than repair shop would be...most Quantaray were made by Sigma/Tamron/Tokina/Cosina...since most are quite old now, (I have a 70-300 Quant. in Sony A-mount, still works, makes shots as well as any older Sigma/Tamron/Etc.) I'd go with a good, later model used Tamron/Sigma/native lens...you can pick them up for cheap (compared to new) maybe $100 or less (or more)....just make sure you have recourse (return/refund) if it has issues. Do look inside carefully, watch out for mold/fungus.

If you are looking for Sony A-mount or Nikon F mount (my case), or other brand mount, many of us (I do) probably have extra good working lenses we can sell quite reasonable. If $$ cost $$ isn't an issue, then there are a ton of good lenses available through many platforms.

Depending on camera type - If the A/F did work but stopped, it is either dead screw drive AF geartrain (parts for old lenses are hard to get, I know firsthand), or bad electronic connection...if electronic, clean all the contacts (camera and lens) with contact cleaner or rubbing alcohol (used sparingly) and try it again. If mechanical geardrive, probably best to put it on display, or toss it....not worth the cost to repair. Good luck!!!

Depends upon which section of the state you are from. The folks in Chapel Hill only know how to drink, spread covid-19, and cheat at NCAA sports......Durham is only good for burning things and rioting.... The only honorable ones are from Winston-Salem....

What does that last post have to do with either repairing an old lens or the proper spelling of the devise that focuses the image on the sensor?

I'm not familiar with this lens but my guess is that there is a problem between the connectors on the camera and the lens. Recommend you take the camera and lens to a good repair shop and have them check it out.
