I bought the Canon 70-300mm zoom lens, and one big draw back for me, is that the focus ring is a fly-by-wire focus ring, where as I am use to the mechanical hard stop focus rings and prefer those.
I was thinking of selling them lens and getting a zoom lens that can zoom up to 300mm but with a hard stop ring, for hopefully around the same price.
I’ve been looking online but all the stories do not say if their telephoto zoom lenses are hard stops ones or not, in the specs, and they always leave that spec out. And the camera stores are not sure, as it is an unusual request for them.
Does anyone know if you can get any hard stop lenses that can zoom up to 300mm that can fit a Canon DSLR, that would be in a similar price range, around $600 hopefully?
Yep I want it to shoot video. I got a telephoto lens I wanted to shoot video with before, but I had trouble using a follow focus on it. Someone told me it’s because it’s a fly-by-wire focus ring, where as I need a hard stop focus ring, to pull focus, if that’s the problem.
Yes. That’s why I bought a Follow Focus unit that has settable hard stops. You can set the stops anywhere you want. I always set to max and min focus– Zero and infinity. The focus ring stops at those two points. It doesn’t keep turning.
Okay thanks, but one of the problems I have with the fly-by-wire lens, is let’s say on a follow focus I set point A and pont B, and I want to focus from one to the other.
On a fly-by-wire, once I set the points, all of a sudden Point B is not the same anymore, cause the fly-by-wire, does not work consistently cause of the electronics inside it. So even if the follow focus has hard stop, any points you make on it, will be consistent cause the fly-by-wire itself, is an electronically inconsistent ring system. How do you pull focus then?
Okay thanks. But I was told before that the problem I was having with accuracy, is the fly-by-wire lenses, and that fly by wire lenses will not work with follow focuses. So is that not true, and they do work with them?
Okay thanks. Maybe I’m doing it wrong then. When I make a mark on a follow focus with a grease pencil, and then want to hit that mark, the mark on the lens is not the same each time, because the electronic components in the fly-by-wire lenses, are changing the mark each time.
How does one pull focus on a follow focus if the electronic components in the lens, is changing the focus marks each time?
