When movement is restricted, less orthodox solutions must be found. In search of the tiny tiny C-19 rascals, there is a need to bring out the really big 'uns :)

The NEX-5N is almost invisible at the rear of the huge 360-1200 Nikkor.

This is the K version, with a very low serial no. (174067). According to Roland's Nikon pages, 56 units were made of these impressive zooms in the K livery. With AI and AIS models, the total still is well below 200 samples. Thus qualifies as a Nikkor rarity presumably.

It has had its foot extensively modified to allow mounting it securely on a robust tripod. The original design was severely flawed and inadequate for such a massive lens (it weighs more than 9 kg). I also added a "G"-type CPU. The lens was sold as "junk" by a Japanese dealer many years ago, because it had been stored under damp conditions and had lots of fungus inside.One could not look through the lens -- it was totally opaque. Otherwise it was practically unused. Turned out the fungus was only on a single glass surface and easily removed. Thus the purchase was a bargain for approx. 500 USD incl. shipping.

No C-19 indicators seen -- so far. But I'll keep looking.

Tried Ai Nikkor 200mm/f4.0 and Fuji TAC IR90 filter on the unmodified Sigma fp.

Akira, what's your opinion about the Sigma FP's IQ and handling?

Peter, I was pleasantly surprised by its IR capability.  I used D2H and D40, both of which were known to offer usable IR-capability without modification.  But Sigma fp shows higher sensitivity to IR than any of them.  Given the up-to-date high-ISO capability, it is the best camera for IR without modification, so far as you can live with the tripod.

Of course, unlike D2H, Sigma fp doesn't seem to suffer from IR contamination at all in normal situations.  That is also surprising.

It could be capable for the astro-photography to shoot nebulae containing H-alpha spectrum.

Thank you. I thought the camera was mainly used for video but it is apparently a ver capable photo camera too!

That's nice Frank.

Thx. Yes, the 2.8/60G Micro is still a superb performer!
