I appreciate any feature (like the breathing elimination mode) that can help a non-professional (like myself) to pull focus. I think you are taking the right approach....
But eliminating breathing can be take care of quite easily in post.
Don't get me wrong on this I think features are great. It's just the tried and true methods are most often there because they work. For example a mercedes with every feature on earth but no steering wheel or brakes is probably not going to make the driver that happy even if it has the most advanced GPS system on the market.
I pulled focus for almost 10 years and the best young focus pullers I now work with still use traditional methods they just have a few new tricks and tools they add to them.
I am pretty sure I am doing a really bad job of explaining the small additions needed to make this as good if not better then current high end models on the market. What I am recomending seems to me like it would be a very simple thing to add. I also am in no way undermining what Curt has done as I do not have the skills to achieve what he produces and does. I do however have a long relationship with the follow focus wheel and even though different things about it may seem small I can assure you that many things that seem unimportant are key elements. Think of it this way there are big time proffesional focus puller making over $250,000 a year that spend 12hrs or more a day for possibly their whole career just spinning that focus wheel. Even though it may seem unbeliveablysimple their are key things that seperate a good follow focus from a prosumer one. I understand Curran that you want features that will help you or the focus pullers you hire to do a good job its just you would be suprised at how effective a simple white marking disc or a raised rotatable focus mark will be in the process.
