There are many old manual-focus lenses available for a pittance that are gems of optical excellence. However, not every lens ever made is optically spectacular. Some, perhaps, even transcend mediocrity into the realm of sheer imaging horror. Have you got any in your lens drawers? Perhaps some guilty pleasure that you hastily bury under a pile of Zeiss whenever company is coming over? Here's a thread for you to post your (least) favorite so-bad-that-it's-good (at being bad) lens.
I'll start off with a lens I just acquired, based on the reputation that preceded it ("Nikon's worst lens, ever."): the Zoom-Nikkor 43-86/3.5, in the original 9-element optical formula (before it was later revised to a merely poor lens with 11 elements). I did go for a multicoated Nikkor-C version, because I'm not a complete barbarian. Picture of the lens in the recent lens purchases thread.
The lens itself is a solidly-built one-touch zoom, compact with easy handling and smooth mechanics despite being almost four decades old. On the outside, actually quite nice --- attach it to a camera (Canon 5D) to see what lurks within. Through the viewfinder, you can see the distortion bowing from serious barrel to pincushion as you zoom; towards the long end, a "soft focus" haze is visible even in the viewfinder. Take a few shots, and you'll see the strong abrupt vignetting in the corners (that doesn't really go away with stopping down). You might be able to get one tiny spot, right at the center, in acceptably sharp focus, surrounded by a smearing vignette. Wonky focal plane curvature (I'm not exactly sure where it goes, and I bet it changes a lot with zoom) makes it somewhat unpredictable what else in the image will be in focus. Surprisingly, there's little lateral CA, and veiling flare / contrast is well controlled.
I don't have a sample photo because I never took anything worth keeping, but my lord the Nikon 50/1.4 AF-D, lots of veiling haze and absurd amounts of chromatic aberration. Became decent around f/2.8. Makes you wonder how affordable and light a 50/2.8 could've been...
a lens is only as bad as the person using it. but at the same time, theres a weird attraction to using flawed designs that i totally get. i was shooting with a pen f 42/1.2 for a while and while it was loaded with issues, sometimes it made pictures way awesome.

Yeah hate the spoil the party but so far I like these thread shots Like Roger I'll have to dig through my hard drive to see what I've got (that I didn't trash already).

Kinda like that Nikkor zoom (isnt is first zoom they made)?
Nope; it's the third. There's lots of great historical information available on the mir.com.my Nikkor pages. The 43-86 came after the 85-250/4-4.5 and the 200-600/9.5-10.5.
Ironic. I don't think of lenses with lots of aberrations (poor sharpness aside) as being bad. They're the lenses I look for and use when appropriate. They can make for interesting images as long as you work with them rather than expect something they can't deliver.
Michael, I'm glad you didn't start this thread based on the Tamron 500 I sold you!
I've owned a LOT of lenses, and i really can't think of any that stuck out as dogs.
One of Ken Rockwell's "top 10 Nikon worst", the 18mm f2.8D, was one of my favorite lenses of all time.
My worst lens ever was the 400mm f/5.6 T-Noflexar before I figured out that its rear element had been installed backwards. It was so bad I couldn't focus it. It's still my worst lens after turning the rear element around but then my other lenses were made in either Wetzlar, Solms or Midland.
So far this is a great thread. Those shots from the Nikkor 43-86/3.5 are incredibly bad for a Nikon.
I don't have any examples, but the worst lens I ever used was a Canon 20-35mm f/3.5-4.5. I can't believe every copy performed that poorly, maybe I just had the worst one.
