I am not an expert for those things, futures, stocks. I lost heaviely on Chinese stocks. It was a Lantian stock that was a hoax to suck money from unwary investers.
And the court refuses to handle cases like this. It is really very bad!I think I may try to catch an UFO image with this tracking lens at home, or peep into others' private life.
No I won't do it.zhang xk

WOW,
I that's very very nice, china super lens, anymore monster like that 500mm?
every see one of those 300 f/2.8 russian lens in BJ?
China stock market "was bad", but the governement is doing everything it can to improve it. It has to get better (local investors sentiment), otherwise, once the financial market is wide open, it will get raid by foreign institutions, just like how our country was raided in the late 1800s.

There is also a 1500mm F11 lens for a JSH-136 military camera, and a 900mm F9 for a DWY-2 camera developed by Changchun Nr.4 research institute.
I have seen a few times the Russian 300/2.8 lens and the Pentacon 500/5.6for RMB 4,500-6,000 in Beijing.
I am not sure of the focal length of that tracking lens. It must be at least 2000mm or more. With a Russian Tourist eyepiece, I can read a newspaper 200 meters away.

Zhang, just make sure no one is sitting on a toliet holding that newspaper.. .
1500 F11, that's a Mirror Lens?
Saw the Pentacon 500 before, didn't buy it. Used to have the 300mm, 50mm for P6, still have 180mm, 80mm for it, all at dad's place in Guangzhou...
That's my first set of camera that I purchased myself. Had a F401 when I was a teenager..

I used to have the 300mm F4, but sold it. I have a black version 180/2.8 Sonnar. That IS a superb lens. Now I still have a 50/4,65/2.8,120/2.8,180/2.8 and a Russian P6 mount 2X teleconverter. I like the 65/2.8 Flektogon. It is much lighter than the 50/4. Now people in China began to appreciate those East German optics. I always use a 35/2.4 Zeiss Flektogon on my 300D for close-up shots.
I am not sure if that 1500/11 is a mirror lens. A guy offered to sell that 500mm F4.5 lens for a mere RMB 1,500 last year, but he withdrew the auction.:bang:

Yes, I have been collecting vintage Chinese watches since last summer, and posted many images on that site. I am also one of the moderators on the only English on-line forum for mechanical Chinese watches.
Will, many people are viewing this thread. These unknown Chinese optical products are very interesting.

What is this WuBai? I never heard of it. Do you mean Changzhou?
I have a 500mm F6.3 Russian mirror. It is less sharp than my Chinese 1000mm F8. Those military optics must have a 50-70 LP/mm at the center.

I guess few people could afford this apartment even if they work hard for a whole life. Believe it or not, an apartment of about 600 square meters sold for US$ 11 million in Shanghai to an unknown overseas Chinese. That is RMB 88 million just for a good view of the river!!

The best penthouse in HK is about $30k HKD per foot (not meter), I think the size was 3000~4000ft, roughly matches the price of that...
I used to be in real estate when I just got back to HK. Penthouses with great view cost more than houses in the peak area (most expensive) in HK, since their views are unique.
I remember hearing my ex-employer's QC manager, talking about the company's new car (Toyota Crown Sedan) on one lunch break.
"Even he work his whole life, he can't even afford a desent car".
