great idea, but it's sort of a sad statement about sony design if that lens is so difficult to maneuver.

You obviously have no idea what you are talking about, since the sony control wheel is actually very easy to control.



Do you have any idea what a follow focus is used for???
They provide a different plain to control focus. They allow very subtle control over focus. Take a look on the web and see to what levels of camera us a follow focus.

It's like saying that all of the consumer camcorders have a poor design since they need a 35mm adapter to aquire better depth of field.

This is in no way a needed improvement but an alternative method and one that opens a creative door to using a consumer camcorder in a professional manner.

Sony is not god. You felt a need to improve upon it. You can say it. You're right that I'm not familiar with that particular sony product, I'd hesitate to use a tool, improvised or designed, that would throw off the camera's balance, thereby making the tripod less reliable during a movement.

Neither do I think nor did I state in any fashion that sony God in this post.
So you must have some sort of chip on your shoulder about sony, and no matter what I would have posted, you would have found a problem with it since I said I used it on my sony SR12.

I felt no need to improve upon it. instead What I did was creat a device that is used on cameras that span from canon HV20/30, Panasonic AG-DVX100
AG-HVX200, to the RED ONE and many others.

This project was not and improvment but a DIY (that means Do-It-Yourself in case you think its code for some sony defect of somthing) project of a very common professional filmmaking industry mechanism which is usually operated by a focus puller, whom is often called the 1st assistant camera, as stated in the wikipedia link I provided for you below.

So you clearly make knee-jerk statments without any true knowledge of what you are commenting on.

So I will help. Here is a link to help educate you and expand your mind. It is the Wikipedia info on a Follow-focus. This is just a quote from the site:

"A follow focus is a piece of equipment that attaches to the focus ring of a manual lens via a set of rods on the body of a film or video camera. It is ergonomic rather than strictly necessary; in other words it does not contribute to the basic functionality of a camera but instead allows the operator to be more efficient and precise."

Please do yourself a favor and read further here: http://en.wikipedia.org/wiki/Follow_focus

Thanks. Thats why I shared it so any one with a limited budget interested in these sort of controls can get involved and have FUN.

Some people cant have fun as you can read above: All they do is look at the world with hate and comtempt.

I may have made a mistake posting my idea on this forum.

Hi Paul,

A google search for 'sr12 follow focus' brought me to this discussion and I was disappointed to see that it had been removed. For the sake of those who own sony's and who are interested (many I am sure) would you please re-post it?

Thanks
Mike

Love it!!
Thanks a lot for putting it back on. Are you planning to make a fortune on ebay or are you willing to share some dimensions? I think I would like to have a go myself.
Cheers
Mike

You only made a mistake if you thought (or forgot about) that there would be no "nay-sayers" out there. I agree with you....just have some fun and enjoy life while you're here; and don't sweat the small stuff (or small people).

Whatever. I've been following focus on industrial cameras for 20 years, and I've never needed help on a camcorder to achieve it. I already wrote that you had a good idea, but personally I would never attach an accessory to a camera which would change its center of balance on a tripod.

Expand your good idea. Would it be feasible to add a transverse bar and counterbalanced grip, so that the whole rig could become portable? Don't restrict fine control or stability to a static shot.

Whatever!!! what exactly does that mean whatever!!!! and your first response in your post followed with "....but it's sort of a sad statement about sony design if that lens is so difficult to maneuver."

So that statment is what the focus is on. the fact that you have no clue.
you initially thought it was a modification to help with the focus of the sony camcorder purely based on YOUR comment.

And you still state you dont need help with focus on a camcorder. But what you fail to see is that it is not needed but desired by many to help with the artistic control of film making albeit the use of consumer cameras.

If they were not desired there would be NO market for such a device.

Did you read the link I provided? Doesn't appear so.

Check out this forum: http://www.hv20.com/forumdisplay.php?f=7 and read about all the modifications that other do.


I was alot like you. When I read about 35mm adapters also called DOF adapters used on HD camcorders, I thought what a waste; Using a device to degrade the image quality of these HD cameras. But Now I use one.. Why.. Because I realized I have a creative nature and the only thing that matters is what makes me happy. So a 35mm adapter and follow-focus devices fit into my end-game.

visti this video from Philip Bloom: http://www.vimeo.com/1420964 He uses a Sony EX1 and Letus Ultimate (35mm adapter) also he uses a follow focus on his equipment.

He has been making films for 20 years here is his site http://philipbloom.co.uk/films/35mm-films/



So when you say "Whatever. I've been following focus on industrial cameras for 20 years, and I've never needed help on a camcorder to achieve it" and "I would never attach an accessory to a camera which would change its center of balance on a tripod" I can only surmise that you have very limited experience and regard your opinion as an amature with a biased opinion. MY tripod head is adjustable to get the center of balance where I want it. Did you know that tripod heads could do that???????I could go on and on but to what end. to turn you on to something artistic and imaginitive that you will never appericiate.

Its up to you to expand your mind. But its not up to you to try to keep mine boxed in.

And as far as this comment by you: "Expand your good idea. Would it be feasible to add a transverse bar and counterbalanced grip, so that the whole rig could become portable? Don't restrict fine control or stability to a static shot" Did you not watch the video. It was clearly portable while the mirror test was going on. as a matter of fact I mad a complete mount for the camera which hold the external mic and follow focus and much more. it has handles to support it on the shoulder or from the top to be very mobile and follow the action. It aslo fits on my steadicam that I also made and works well. But I guess not you'll say that having a steadicam really shows how poor the sony stabilization system is!!!!!
