TTL and the Nikkor 15mm

[r3schultz]

I just purchase a Nikonos Nikkor 15mm for my Nik V. Does anyone know above what serial numbers the 15mm was modified to make use of the TTL features of the V? According to the seller the serial number of the lens is 203587.

In case your wondering "why didn't you figure this out before you purchased you big dummy". The auction included a working Nik V, 15mm Nikkor lens+viewfinder, sb102, plus double bracket and double sync cord. I figured it was a good deal if not ttl and a great deal if ttl capable........thanks for any input.

I could be wrong but the lens should have nothing to do with TTL. TTL is a sensor in the camera that allows it to "talk" to the strobe output.

Hi,

I do not have the numbers, but this might help. The old style Nikonos 15mm UWN lens, designed for the Nikonos I-IV, is less compact than the new style 15mm: the rear lens element protrudes into the camera body. It is almost 1" long (compared to approx. 1/4" long on new style), blocking TTL metering system on the Nikons V body.

So, check out that distance...

Meanwhile, I will see if I have some photos or can find the numbers...

Mike,

In this case you are wrong. The physical sizes of the two lenses differ. The older lens did not fit in the TTL-capable Nik V in such a way to allow TTL to function.

The old sytle 15mm has a longer rear lens element than the new style. It is so long that its physical characteristics blocks the TTL sensor on the Nikonos V.

I don't know the serial numbers range that you are asking about but I can tell you if it is TTL compatible by looking at it. The old style and new style 15mm lenses look noticibly different from a side view. Can you post a side view picture of the lens?

If you bought it on ebay recently you can PM me the Item number and I can take a look on ebay.

Thanks for info so far.....I am familier with the extended rear element of the 15mm being non-ttl. The problem is I am basing all of my assumptions on pictures on E-bay and the sellers response regarding the serial number. The item number is 160078077181. I'll have it in my hot little hands in 3-5 days, I just was curious on just how good a deal I got, once again thanks for responding.

Hi, again,

Here is a photo of the TTL-Capable Nikonos 15mm lens:

You can see that the rear protrusion is small...

I looked up the item number on ebay and saw the photos.

It is the new TTL compatible version.

Here is the old style lens on ebay. Compare this to Joewr's link and you can see the new style body is larger.

Hi!

Now that is what I call great teamwork!

I have another suggestion that, unfortunately, is going to cost you some money. First and foremost, you need to have a close look inside camera. You can just take the lens off and open the "rear door". Look for any signs of leakage(or flooding) or corrosion. Leakage will usually show up in the form of salt crystals and/or corrosion. The corrosion will often be greenish from copper. If you see none, that is great news. If you do, you are in for a very expensive surprise.

Even if there is no evidence of a leak or flooding, it would be prudent to have it checked by a reputable underwater photography shop. I can lead you to a couple if you do not have that info. This may sound painful, but it will be more painful if your camera leaks on its very first dive.

All the o-rings on camera, the cables and the strobe will need to be replaced. If it were my gear, I would send the camera, cables and strobe to a shop for inspection...

joewr...

Tell me about it! This will acually be my third Nik V. Don't need another camera but auction was too good to pass up.

On recent trip to Curacao we used Ocean Encounters. The owner's son (Chris) noticed my Nikonos gear and ask if I have lost any. I replied, "no, why do you ask?" He said they used to be a big Nikonos shop but since the popularity of digital they had a bunch of Nikonos stuff just sitting around and if I wanted any or all of it. There pile of stuff consisted of a Nik V body, a couple of 28mm lenses, a 35mm lens, most of a close-up kit, plus other assorted odds and ends. To make a short story out of a long one the body cost about $400 at Southern Nikonos to get back to life (new "shoe-box and flash synch port). Not to mention the "free" lecture from Bob.

So.......after this, I'll have 3 working (if I'm lucky) bodies. Your right, I'll need to service everything with the body probably ending up back on E-Bay.
