Canon's push focus ...or everything else?

So yesterday, I was trying to test:
1) a new color curve
2) the Home made igus slider
3) Nikon on Canon lens.

Subject: 2 and 3 year old kids playing.

What I discovered is that with any manual focus lens, where you can not control your subject (it's not a movie where you have everything marked and can do a re-take).

I am finding that my Canon L zoom I am liking more than the Nikon glass where I have to focus it manually.

When I am on the igus slider, I have to concentrate on getting the slide smooth.
I am either holding the slide, or pan head handle. Focus has to be locked, which is fine as long as they maintain the same plane.

If the kid walks backward or towards you, now you have to go to the lens and focus, which would disturb your slide.

For this reason, I am thinking manual focus lenses won't work for me when used with a slide and on subjects that are unpredictable (live event).

In this situation, I think I will rather have my Canon L zoom, where I can keep my hand on the camera, and slide handle, and if I need to adjust focus, just hit the auto focus button, and edit that refocus section out.

For me, it is very difficult to focus, slide, frame at the same time. I can only do 2 at a time. So the slide and frame works, and then auto focus with the button.

The manual focus lenses don't allow me to do this.

I do like them for locked down scene, where I know what the actors are going to be doing and moving. In that situation, I can do all three.

Feedback?
 
i shot a live event with manual nikons on a slider and because i had a followfocus and a nice tripod head attached to the slider i was able to follow the action while dollying from side to side.

At times i had a friend do the sliding back and forth while i concentrated on the focus pulls. I was using a 90mm macro wide open at f2.5 so the pulls were quite delicate. It was challenging but fun.

At the time i didn't have a monitor so i was shooting from the back of the camera which didn't help. I think it would be even easier now that i have a monitor.
 
quite challenging but a followfocus with a spped crank or very short whip will help maintain the center focus on target while slowly pushing the slider with the other hand.
shooting wide open can be a pain if not using an external monitor and working at wild angles...
bottom line being : whatever works for you but try a few options first.
 
Thanks guys, I am open to any option, as I like manual lenses better.

I just need 3 hands to make this work without a monitor or follow focus.

Which follow focus are you using and monitor?
 
I dont like long throw heavy friction manual lenses for the lone operator

I use
Tonkina 16-50 (quite heavy to focus but super short throw)
Canon 24-105 normal canon
Nikkor AF 1.4 (even though I have a MF 1.2) - super smoth low friction
Canon 70-200F4 - too skint for 2.8 normal canon feel

Camera operation is an ART FORM - a high art

I learned what a high art while trying to learn steadicam

Gain steadicam operators sensitivity to all camera operations and you are on your way

To slide, pan and focus is an art

You need to obsess on everything
Head friction being very important

I have a 501 head for my 'jib' and find it is too frictional to manipulate properly

My miller arrow 25 head is the business with low friction - but too heavy for my selfbuilt jibs and sliders

Also balance - front to rear on the head - critical to play with this

Bascialy on a slider im cradling the camera , left hand front on the lens, right hand on the pan bar of the head, slider not touched

This gives a position where you can perform your move and pull focus

And a SmallHD moitor helps you see what you are doing which helps

I use the Manhattan LCD monitor for focusing. The 8.9 inch screen comes in real handy. And looks great for playback when the actors want to check out what you just shot. I also use the IndieFOCUS set up. Low cost and very smooth.
 
I'm using a Lilliput monitor 7in i believe and the CINEfocus from shoot35.com.

Works very well so far. I needed a kit that is small enough to travel over-seas but allows me to grab excellent footage.
