Hi Dan

The Evertz that I know is also a power hog on its own, it also makes the camera very long. If you can use something else (Miranda? AJA?) you will do yourself a favour.

Hello Solo2K6

Welcome to this forum, are a friendly bunch here and like to use our real names - worth remember for the future.

In answer to your question, the SK is designed for cameras up to 19lbs (8.63kg) so it depends on what accessories you are going to hang on the camera. A DVW-790 is usually around 7kg with the lens so a big NiCad battery will take you over weight whereas feeding power from the sled will be OK. If you can get hold of the camera and weigh it you have a real answer.

Hi Kundal

The Tiffen Europe workshop is at BBC Wood Norton which is an easy 2 hours or less from London by either train or car, accomodation is from as little as GBP38.00 per night - less than the train fare.

Next one starts 1st November, contact me directly on robin.thwaites@tiffen.com if you want more details.

Hi Andrew

Sorry, missed this thread before.

Vibration can be for several reasons.

1/ Vibration in the stage.

Usually means that it needs a little adjustment and will vary with camera weight/weight distribution. Usually worse with lighter cameras especially TV cameras where the weight may be far from the centre. Usually shows 25-30mm upwards, normally present to some degree once you get above 40mm. Often shows as individual foot falls. Adjustment means dismantling the stage and adjusting the linear "V" track bearings - not something to try at home on the kitchen table. A syptom can be if the camera dovetail is an easy/sloppy fit.

2/ Sloppy camera mounting plate.

This is more to do with side to side movement and the inability to hold a constant balance. Sony plateas are adjustable but something like a Chrosziel replacement is a better bet (although expensive). Probably worth the investment in lost balancing tim e and frustration.

3/ Sympathetic vibration.

Typically from the monitor as this is a heavy item (CRT in your case). The vibration travels back up the post and eventually into the camera, can also happen from loose battery mounts. Looks a little like the stage but usually smaller movement but more constant. Solution is to make sure that anythiong that could possible move is locked down solidly.

4/ The lens.

Strange but true, TV zoom lenses are more prone than you might imagine for groups of elements to move around inside. Cure? Change lenses and get the production company to get it serviced.

There are other things but these are probably the most common, others are detective stories.

Good luck

Robin

Hi Andrew

How old are the batteries?

Robin

Hi Lars

Just to satisfy my curiosity first are you doing much film work (or turning it away!)?

Robin

Hi All

Tiffen will be holding a social get together on the evening of Monday the 11th. Put it in your diary but come and see us on the booth to get details (11.409).

See you there

Robin

Hi Tony

Areas to check out and eliminate one by one.

Direct vibration. Loose camera mounting thread, bottom of camera not flat, camera mounted at extreme end of dovetail plate and out of stage area.

Sympathetic vibration. Loose battery, monitor, top light, anything. Don't be fooled if it doesn't happen with the other camera, it may have a different resonant frequency.

Tape transport. Seen this from heli shots but really unlikely on this since you need considerable vibration to make it happen in the first place and also the inertia of wide tape.

Loose lens optic. Not impossible and difficult to detect. More likely than tape slap.

See if you can borrow another Z1 and make it happen to eliminate the camera.

Good luck

Robin

Hi Gerard

Tricky, the Preston association infers interference but it could also be a power thing or complete coincidence. Give me a couple of days to check this out and meanwhile send me your e-mail address to my desk at robin.thwaites@tiffen.com and I will come back to you directly.

Robin

Hi Gerard

How old is the rig? Does it have a separate stobby antenna sticking out?

Robin

Congratulations Mikko, probably works better than Leggo :)

Back to the subject, Spice Girls was shot by Roger Tooley as was the Spice Girls movie.

While at OpTex I saw an arm which had been treated to a very heavy dose of ACF-50 and left. It does not seem to have the same detergent or penetrating properties as WD-40 and remain almost sticky to the touch.

The problem was that this had then attracted a lot of dirt and it needed to be stripped and cleaned with solvents before we could even tell what work was required. It probably prevented any corrosion but it is difficult to say if it washed out the bearings.

Hi Guys

Please do not use WD-40, it is a penetrating oil with detergent in it and will wash out existing lubricants and loosen screws.

Hi All

Now that BBC Wood Norton is up and running properly again we will be holding a three day introductory Steadicam Workshop starting on July 5th. We will have a variety of gear there, old and new and including new systems G-50 arms. If anyone is thinking of attending, Wood Norton is around 2 hours out of London but gives us access to studio and outdoor facilities with on-site accomodation available.

Please come back to me by e-mail to robin.thwaites@tiffen.com or phone at +44 1869 34 38 35.

Hi Jason

You can pop rivet the guides back on or make a nice upgrade and do it with good old nuts and bolts. Use washers to prvent the screw heas or nut eating into the plastic. Also use nice big washers where you attach the waistband to the spar. If you have metalworking ability/equipment you could make up a little tapped plate to back up the plastic.

Robin

Hi Thomas

I think the Evertz will but it is big, heavy and power hungry.

Robin

Hi Guys

One further thing is that some of those monitors use small trim magnets which are glued to the yoke or CRT to adjust linearity. These sometimes fall off and need to be glued back on so check for loose magnets in the monitor before anything else.

Robin

Hi Imran

Ring me when you have time.

Flyer has a better arm and since your camera is an SR 1 it is 12 volt so you will be able to power from the sled to keep the weight down. Watch out for the extra that you might need to add if you use focus. XL 2 no problem.

Robin

Hi Gregg

Feel free to contact me directly if you need any help.

Hi Donkey Kong

Firstly I probably should say that we tend to use real names on this board - it's a small community so good to be sociable.

We try to run 4 workshops a year here in England (although I had to cancel the last one due to venue problems). These are 3 day introductory courses and maybe what you are looking for if you fancy traveling.

Please feel free to contact me at my desk e-mail for details robin.thwaites@tiffen.com.

Hi Thomas

What is the weight of that camera? I remember them because I worked for the importer years ago but have no idea how heavy they are.

Robin

Hi Matt

Looks like fun until you think hot weather, full fire suit - I know several guys who have done motor racing and they tell me it's a killer.

Robin

Ring me on Monday.
