Nemrod Siluro

Nemrod Siluro - Flash unit with M2 bulb
I have some diving and underwater photography experience, but I had never seen or heard about this camera, until I saw one on OZBOX photostream, at Flickr.

I googled it, just to try to know more about it, and found this nice example on a local auction site, contacted the seller, went to see him and the camera.
It was a nice young man from Vila Nova de Cerveira. His father at some instance bought this camera but had no idea of what it was, the son insisted that it was a diving camera, he didn't believe it due to the flash unit, he thought it wouldn't work underwater.
They made some inquiries and found what it was and had it for sale.

After inspection of the camera, money changed hands and I came home with this beauty.

Nemrod Siluro w/o flash unit

This camera was made by Nemrod Metzeler, S.A. in Barcelona, Spain.
and it was distributed by Vilarrubís y Sagué, S. A.
Sagrera, 44 - 55, Barcelona - 13, España
The Nemrod company, named after the bible character of Nemrod the hunter, king of Babylonia, was a manufacturer of diving and spearfishing equipment, they produced this camera from 1960 to 1966
It's moulded in a kind of heavy Bakelite, known as Novodur.
It has close resemblances to the Mako-shark, by Healthways, California, with the benefit of using 120 film instead of 620 and having a dedicated flash unit, invaluable for underwater photography.
The lens is a 70 mm fix focus and aperture, 1-2,5m, f:16
The shutter is a very simple single speed type, 1/55 sec.
Built-in inside the back there is a pair of lead weights to make it's buoyancy neutral.
Made to be water tight at 40 meters.
Valve in the front to pressurize it.
It provides twelve 6 x 6 exposures on 120 film, the film advance, via scalloped knob, is controlled by the ruby window, on the back.
The power, for the exterior flash unit,is provided by a 22,5 V battery and it uses an 100 μF 25/30 V capacitor, both housed inside the body.
Dimensions and weight: 16,5(d) x 27(l) x 20(h) cm, 1.550 kg (including flash)

In a nutshell it is an underwater box camera.

Let's see how it's made:

Or, via the included adapter, XM-1 bulbs

For underwater use white bulbs are the best choice, blue bulbs for topside use.

It's an amazing piece, seen from any angle

Even the sports finder is great

This is a curious feature, the pressurizer valve, you can use a bike pump to do it, it provides positive pressure inside and, if some gasket is leaking, on the immersion the diver will see a stream of bubbles denouncing it, giving him time to take it out of the water, before any damage occur.

The only fault in the camera was a broken piece in the inside, some kind of adapter, that glued quite all right.

I'm not sure what it's function is as you can see in the following pictures: on the left one there's a kind of adapter, that gives an extra clearance between lens and film plane, of about 5 mm.
On the picture on the right I removed the adapter.

Nemrod Siluro - Film adapter (?)  Nemrod Siluro - Flash electronics
I can only guess that the adapter is for close range photography, mainly underwater, and removing it probably it will focus from 2/3 m to infinity, for topside use.
It's just a guess, as the camera doesn't have B position, I haven't yet tested my supposition.
If someone can confirm or discredit my theory I would be must obliged.

#36 Nikon F-601

Nikon F-601
Nikon F-601 aka N6006

This one was a gift from my uncle, Jorge Sá Dantas.

When he knew that I was collecting cameras, he called me to his house and gave me this Nikon F-601, with the AF Nikkor Zoom lens 35-70 mm 1:3.3-4.5  and a beautiful Rollei A110, of which I will tell you about  in the next post.

Nikon F601

This camera was manufactured by Nikon from 1990, it's a middle term between the F-401 (N4004) and F-801 (N8008),  but as it was released two years later than the f-801, some features were enhanced, mainly the focus prediction.
It was the first Nikon camera to use lithium batteries, a 6V CR-P2 type. 

It's a nice usable camera with it's nice auto-focus, maybe a bit slow by today standards, but the electronic rangefinder, as manual focus aid, is quite useful in low light or other tricky situations, with the most of Nikkor lenses.
The metering system is excellent, five segment matrix reading, centre weighted or spot reading.
The exposure modes cover almost anything: full AE, with two option P and Pm, Shutter or aperture priority and manual. Unfortunately in manual mode there is no metering info.
The built-in flash may be used as a fill-in flash or as main flash at close range, if I have the need for real flash photos, I use my SB-28 that woks very well in TTL mode together with it, but you can also use a SB-23, SB-24,...   

Nikon F601 

As you can see above, the controls disposition is the one that we got used with the 90's Nikons.

Nikon F601  Nikon F601

If I can find a week spot in it is the film advance in continuous mode, only 2 fps, my F-301 (N2000) of 1985 had already a 2,5 fps performance. Anyway it's not a feature that I use much, film is too expensive nowadays for great performers.

# 35 Agfa Isolette V

Isolette V
As I told you before: I'm a sucker for Isolettes.

This time I'm going to introduce you to my Isolette V.

Isolette V

This one like some other cameras in my collection came from the *Bay.
At the time this one arrived home I had already three sisters of hers: 

This is a very nice example of an Isolette V.
Manufactured by Agfa Cameraverk München, around 1950
It's a folding bellows, auto erect camera.
The lens is an Agfa Agnar 4,5/85 on a three speed Vario shutter, by Gauthier (AGC):
1/25, 1/75, 1/200 sec. and B, with  flash synch.
It uses 120 film producing twelve 6 x 6 cm exposures per roll.
The film advance, using the round, knurled knob on the top left of the camera is controlled by a ruby window on the back door.
On the right strut, a button, marked as T, if pulled up, in the arrow direction, blocks the shutter release, and,  if the B position on the shutter is chosen, it gives time exposures. 
The shutter release is that chromed tab by the shutter barrel, above the T button

Isolette V
and not, as we might expect, the button on the top plate, that's the front door release.

Isolette V

Like in the other basic models there is no rangefinder or exposure meter but, it has an accessory shoe where I sometimes use a rangefinder and for the exposure assessment an hand-held exposure meter or the sunny 16 rule does the trick.

Isolette V

Some pictures taken with it:

On the above picture I'm using a combination rangefinder/light-meter branded Repometer

My cameras in Portuguese

As you may know I'm Portuguese, I have this pages in English, so I can reach a broader audience.
As from today I'm going bilingual: every time I post in here there will be a Portuguese translation published in Cameras & Cia

#34 Voigtländer Vitoret

Voigtlander Vitoret

This was the first 35 mm Voigtländer camera in my collection. I bought it in October 2008, at a flea market.

It was very dirty and the shutter was frozen so I made it a CLA


Started by removing the top, give it a light wipe with lighter fluid and a thorough clean to the, very dirty, viewfinder:

Vitoret CLA top removed  Vitoret CLA dirty viewfinder

Vitoret top removed viewfinder cleaned ready to reassemble  Vitoret CLA viewfinder cleaned and in place

Next came the shutter and lens.

After a thorough clean, it was time to reassemble it all:

Vitoret CLA shutter cleaned

First the mid lens, followed by it's retainer ring:

And finally the focus ring:

The finished job

Voigtländer Vitoret

The Camera:

It was an entry level camera based on the Vito line.
This was the most basic of a large family, manufactured by Voigtländer  Sohn AG, at Braunschweig, in the former West Germany, during the 1960's.

Compact simple viewfinder type
Vaskar 2.8/50 lens on a three speed, central leaf shutter by Gauthier (AGC), Prontor 125 shutter, 1/30, 1/60, 1/125 and B, with flash sync.
Film advance by a flushed lever that also cocks the winder
The best feature is the very big and bright viewfinder, provided with bright framing lines
The rewind release is located on the top plate, where you would expect to find the shutter release. The rewind is made using the knurled knob on the left of the top plate.
The shutter release is located on the front right, by the lens barrel, a remote cable can be attached to the bottom of it.
It has a film counter on the bottom plate, manual reset.
You can find it's manual at Mike Butkus' Orphan cameras

Some shots taken with it:

Behind the glass

Telhados velhos

Lara in the flash

In these shots and the ones on the respective Flickr set you may notice some blur in the corners.
This was due to an incorrect assembly of the middle lens, during the CLA. Meaning that the A part (adjust) didn't go very well, I know that I checked the focus but, just in the middle and it was fine, for all distances.
I corrected the situation, checked it in the corners and it's good I just haven't tested it with film yet.
