A Vivitar 600mm f8 refractor and Pentax SV mounted on an old rifle stock. This is a non functioning device and will be given to a neighbour who likes to decorate his bar with eclectic 'stuff'.

I used to have one if these... But I adapted it to my Pentax, and later Nikon.

That Zenit has a focal length of only 300mm and stopping down the aperture scares the horses in the next county.

These days, you need to be careful where you use it!

Ah, but with a 2X multiplier it becomes 600mm, and you stop it down before you shoot, otherwise it shakes too much. And yes it does scare horses.

Indeed. I don't think it would be wise to show up at an airport with either one of theses.

What I posted in 2008 at Convert your Fotosnaiper to Pentax! - Steve's Digicams Forums (http://forums.steves-digicams.com/pentax-samsung-dslr-k-mount-mirrorless/141142-convert-your-fotosnaiper-pentax.html)

Having fixed the Tair 300 4.5 lens on my 'new' Fotosnaiper I was soon thinking of ways to use it with my Pentax DSLR. It proved to be really easy.

The Fotosnaiper bracket has two pins that are lifted when the trigger is pulled, the one on the right in this picture comes up inside a socket and normally engages a shutter release on the base of the Zenit camera.

All that is required is something in the socket to make an electrical contact and fire the DSLR. This is a piece of insulating material with a simple metal contact and a single wire to the plug that fits the Pentax camera.

Here it is in position in the socket ready for the camera to be mounted to the bracket.

Thats it folks!

Seems to work too, just cock the lens mechanism, select the desired F stop, focus, first trigger pressure stops the lens down, more trigger takes the shot. I just need some willing subjects, every time the cat sees me pointing it at him he comes running and is immediately within minimum focus range!

I set the camera to Av, manual focus and enable manual aperture is selected in the camera configuration.

BTW, you also need a M42 to K adapter.

Following a moving target is so easy with the Fotosnaiper rig. I set the focus and run burst of exposures while she ran through the focus zone. This is with the lens wide open, 4.5. and shows the full frame.

This is a bit soft but those tractors are just under five miles from the camera,and it's a still from a video clip.
Now that's a zoom.:rolleyes:

Photo sniper camera!

Would be more fun if you could program the shutter sound of the camera to make the sound of a gun shot :} Makes taking photos of politicians a lot more fun.

A friend showed me his Russian scope with phosphor gas image enhancing. I trained it on a radar base 5 km away and was surprised of the clarity and detail. I then stuck my tourist standard Olympus digital camera on the eyepiece to take a photo and it knocked the camera unconscious.

You would have to be a bit lacking in imagination to wander about with one of these - remember what happened to the poor bugger with the table leg in a plastic bag!

I found an old 'rifle grip' on ebay for my S9500 but was unable to use it with my 350D (no place to screw in the cable to the shutter button).

Answer, a couple of cheap tactile switches and a 3.5mm stereo audio socket.

Now I just plug a standard stereo audio cable (3.5mm to 2.5mm) and it works fine.

What would really be fun would be to make a fulgurator!

http://juliusvonbismarck.com/fulgurator/bilder/knarre-web.jpg

It is a slide projector not a camera! The image is projected when the flash of another camera is detected this is not noticeable but when the other photographer looks at their picture they see your image superimposed on their's, could be very spooky!

John Hill - wear a ballistic vest and you should be ok,police marksmen are trained to aim for the centre of mass.

Since there has been some interest in my modified 'rifle grip', I attach camera remote pinouts for anyone thinking of building their own.

www.doc-diy.net :: camera remote release pinout list (http://www.doc-diy.net/photo/remote_pinout/)

And here is a home-brew remote including a 'bulb' setting.

Homebrew Wired Remote for Canon EOS 350D Camera (http://martybugs.net/photography/remote.cgi)

Many cameras use standard 2.5mm stereo plugs/ sockets but some of the Nikons use special connectors; the only way I know to get these is to buy a cheap remote from ebay and use the cord & connector from that.

I tried just fitting a standard remote to the front of my grip, but it felt too uncomfortable and was difficult to operate - hence the use of switches.
