p.5 #1USSR made lens image thread(Helios, Jupiter...)
The main concern for me about these lenses is that the optics are clean,
the aperture works, and focusing is smooth, IQ is a gamble due to to production tolerances, even if it turns out to not have great IQ, you can always use the body as a donor, if you happen to find a sharp one that has body issues.

I used Hugin, which is a GUI for Panorama Tools. The input for your pictures allows you to specify that the source images are from a fisheye lens of a specific focal length. From there, I had to set about 30-40 points to fully correct the fisheye distortion and merge the photos.
If they are not can you put me onto the correct items? I am in Canada so the closer the better. I have never bought anything from Russia before. =]
I will never buy from Russia again...As far as I am concerned they are all a bunch of swindeling b/stards! I bought a Helios 40 85mm f1.5 from Russia that was adverstised as being in "perfect condition". The delivery was 3 weeks overdue from what I was promised by the seller (2 weeks) and when it finally arrived all the iris blades were completely and irreversably bent and chewed up inside!...I had no choice but to take the front off the lens so I could pull them out leaving the lens without an iris at all!! To make matters worse when I quite rightly and understandably gave the seller negative feedback he gave me negative feedback too calling for being an impatient buyer!!! I was totally livid as this knocked my perfect feedback score down to 96%...I had no choice but to agree to a mutual feedback withdrawl to get my 100% score back, leaving me with a lens that was stuck wide open and no way to get my money back!!!!...I recommend you avoid sellers in Russia or you may suffer the same fate.

Did the pano software do that for you?I used Hugin, which is a GUI for Panorama Tools.

Blimey, its sounds a lot more complicated than I imagined.

That does sound dirty, sorry to hear about that.
I'd look for a donor Helios 40 85mm f1.5 for it's iris, unless there are other problems with your lens.

Gallery from the Helios 44-2-if this truly is a copy of the 50mm F 2.0 CZJ Biotar, then the search for a Biotar in good shape can end right now. My Tessar derivatives do a better job at F 8.0 than this:

Thanks! This is the Ray mine in central AZ. I shot these from the one vantage point open to the public. First time I have ever shot anything with such a long (effective) lens... my Bogen ballhead was definitely not up to the task! Thankfully the little Oly's in body IS worked well enough to take out motion blur. They are going to be used in an article I'm publishing in a couple weeks.

My new MIR20N 20mm f3.5
Not as sharp as I'd like and the CA can be a bit much.
Recently got this lens myself, only it's the M version (M42 mount). It's certainly not bad once you stop down a bit, but the extreme corners are pretty awful on full-frame as the sharpness drops off pretty quickly, it's pretty good in the center though.

On my copy the IRIS doesn't close uniformly, one of the blades lags behind the others.
The CA seems to show in high contrast conditions, I'm going to have to do some testing to confirm that, and that infinity is sharp.
It is a fun lens for sure, I'll post some of my other pics from this lens from Saturday.
