So it looks like the space for serial number and brand name is left blank for later as the fate of this lens is yet undecided. This is a stem cell of a lens! |

I'll almost consider that a slam dunk - but the cosinas seem to always have a hood, the focus ring is clearly larger on my lens and the markings are a bit different... I'll say probably cosina for the mo.
UPDATE and the cosina looks the same as the vivitar I mentioned, and that has a 55mm filter size not 58mm.

I always wonder what makes people sell lenses for $0.99?
Is it even worth going to post office?
Maybe they make some money from the shipping cost? |
If you list a crappy lens (or indeed anything) in an auction you are risking it going for the start price. Start it any higher and you will not get bids. I did this early on in my ebay career and sold a nice lens for £1.04, now almost everything is BIN unless it had proper value.
I have recently sold two mediocre zoom lenses on ebay. I looked what the average bid sale was and on both it was £2 to £5 although several went for 99pence. I looked at what the average BIN price was and it was £8 - £12. So I pitched mine at BIN for £15 including postage. I could have done it for £11.99 plus £4 postage and made the same but the free postage gets them every time.
One sold within hours, one sold about 4 days later. They were on a 30 day listing.
I'll not make a profit here, thats not the point but I'll be £20 better off and the lenses were part of a bundle which was a helluva bargain anyway.
I bought a camera in full working and mint condition for 55pence. I may use it and sell it on, I'll get £18 easily

Here is my bargain lens that I bought for this challenge. 99 US cents plus 7.05 shipping from ebay. A YUS 135/2.8. These images are JPEGs with no post processing taken between 200-400 ISO on a sunny day. I used a hood and mostly apertures between 8-16. The lens is a heavy little brick - 8.5 centimeters long, 435 grams, C/Y mount, focuses well.
I was pleasantly surprised with this bargain lens. With a bit of contrast boosting in post processing (which I did not do here), it seems quite capable.
This flower was taken a bit more open, at around 5.6, I believe, maybe 4?

But why? If I see a lens worth at least $20 which starting bid is $5, I will bid anyway. It'll still be a bargain. |

Here are some pics from the mystery 200mm.
It's not very good, particularly wide open, when it is very prone to flare, even with a basic rubber hood. At smaller apertures it did show some decent sharpness. Note that I was battling the inclement conditions due to ex-hurricane Gonzalo. And it took me a wee while to realise that I have only one click per stop on the aperture ring - oops.
All on my G1 with PK adapter. JPG's resized.
100% crop, f8.

So finally I have it on my hands. Unfortunately, the mechanical condition is very bad (but glass is ok). Helicoid rails are broken, 4 out of 10 iris blades are destroyed, A/M switch is broken. I assembled the iris using only 5 blades. The lens currently cannot focus due to missing rails. I think I'll try to make them from some piece of metal. The blades can't be made so this lens will be a wide-open only lens, however the iris works normally and it gives crazy bokeh when stopped down.

Hmmm, this sounds like fun! I can't buy anything new right now, but I do have a knackered Chinon 28mm f2.8 that I picked up for a couple of quid last year - seller said it was mint, but when it came the auto aperture didn't work and it wouldn't focus to infinity. Kept it rather than paying the return postage, I might try to fix it up for this

Since there's no film to use, I did one TtL (Through the Lens) shot as the ad showed me how.
There's an actual wire hanging inside to prove the camera/lens' authenticity.

I found this thread and thought I'd better have a go.
Just won a Sigma 39-80mm f3.5 with a Minolta mount for £0.99 plus £4 postage. I found it on ebay with a 99p startingprice and couple of hours to go and left a max bid of £1.20 on it. Wasn't really expecting to win it. This could become addictive!
It claims to be in full working order. Can't find much info on it but, for £4.99 all-in, it doesn't matter if it's not great. I've already got a Minolta SR to M4/3 adaptor so I'll be back with some pics once the lens arrives.

Cracy bokeh.
It is a good idea to recycle lenses with defect or missing blades.

Initial experiments with the super-cheap 99p Sigma 39-80mm f3.5 haven't been very successful. Haven't managed to take an even half-decent shot with it. Optics not as clean as I'd hoped. I think it's fungus – not sure, never had it before – a covering of small dots on the rear optics.
This may mean that I have got my money's worth! For 99p what was I expecting?!

Well for $0.99 I also got a perfectly good as new 135/3.5 preset lens named Vorn, however these lenses appear under many different third-party names. I have an identical one named Aico. I'll do samples later since it's too dark now. |

Huh. I paged through all fifteen pages of this thread and realized I didn't post any pics taken with my cheap Yashinon 50/1.7. I should do something about that, It got me to thinking and I actually have two others that will qualify. About a year ago I bought a new old stock Soligor 90-310 (I think it is) for the opening bid amount, which I think was $10. I was always curious about that lens' performance, dating back to when I didn't know anything about photography, really. Turns out it's a real stinker. And I have another old Soligor that's like an 85-230 or something. A two-ring zoom, about a bazillion of 'em were made back in the early 70s. This one's really bad too. It was basically the body cap for a nice Canon FTb I bought off eBay.
I have a NEX 7 now, and I've just gotten a bunch of adapters for it, so now I can try out that old Soligor in Canon mount and see if it's as bad as I recall.

So finally I have a full rule-compliant Mamiya Sekor 58/1.7 - cost $3.95
Here's my proof of purchase: http://www.ebay.com/itm/131314813759
It took so long because I bought it but shipped to other address in order to accumulate several lenses and cut on shipping costs.
Next, I tried to repair it as it was all broken. Finally, I made the helicoid rail part instead of broken one and the lens can now focus properly. The aperture is still missing 1/2 of its blades, it can be normally used within f/1.7 to ~f/2.4 range, any more and bokeh will start to look crazy.
The lens is sharp wide-open. However I use it on a m4/3 camera so I don't know about corners but should be good. Overall it gives the impression of having a calm character. However, it was also the nasty winter weather when everything was dull and gray, also my camera JPEG settings are very neutral. After I've seen the results I feel deep regret I didn't take it seriously and shoot in RAW. Processing JPEG files is a pain so I left them untouched, straight from camera, except the flower shot because I modified it and then lost the original somehow.
The lens:
The landscape (best possible with 116mm equiv.)
The flower (yes I magically found it there right when I needed. Shot through the fence, therefore some blur on foreground)
The rest (I did more than one)

Box said vivitar 9xxxx 28-210mm, lens was actually 77xxxx 28-200mm. Looked in good nick but I found a mechanical problem with the aperture while removing the ricoh pin. Pics were foggy: closer inspection of the internal optics revealed a fungussed/hazed element near the mount end.
Any one familiar with this lens? I'll certainly have a go at trying to get to the fungus.

OK, I'll join in on the fun with my cheap lens find. It's not a crappy stinker of a lens, just a score on what turned out to be a pretty nice performer.
I was the winning bid of $6.50 USD on ebay for a Vivitar 135mm f/2.8 made by Komine circa 1971. With a Nikon mount.
Click here to see on Ebay
I got a cheap Chinese adapter off ebay too. But it can't focus to infinity, so I will need to buy another one!
It's sharp and the colors and contrast aren't too shabby.

Wow, great post with the Vivitar lens apart. I have what looks like a similar bodied Vivitar Series-1 that I will need to do the same for oily blades that are stuck and some inner haze. (28-90mm f/2.8-3.5 Varifocal)
Would love to see more pics and some more details of its disassembly.
I did a fungus cleaning of a Tokina 80-200mm f/2.8. I found alcohol to be milder than acetone, and vinegar-based glass cleaner cut the buggers off well.
As for dust, it's hard to keep the work area from contaminating the lens. A can of dust-off spray is a must.
To minimize on smears, I made sure one side of the element was spotless, put it into place and secured it, then clean off any smudges from my gloved fingers. Seems there will be some no matter how clean.
I rushed a bit and upon completion, discovered some dust got in, and missed an area. So, it will get another round.
I used typical lens cleaning solution and lens tissues from a camera store, they worked best for me. I tried the Zeiss wipe packs before on external lenses, and was very impressed.
