RPPs

[Bob Rudis]

That's what your mom said...

heh heh heh. sorry couldn't resist.

Listen guys... everyone wants more more more.. more this more that.. I want this different, I want that different. We already are giving you some of the best glass out there for a price that is hard to beat... Glass that beats most other lenses out there that charge almost as much for a single lens as we charge you for an entire set. Put that in perspective before you start throwing out things like "design flaw" and other half-baked statements.


Shawn, that's an interesting idea. Not so easy to do as each mark needs to be calibrated, but it's an interesting idea.

As always.. thanks for the feedback.

Ok, perhaps it was half baked. I apologize. No doubt the RPP's are excellent glass, at an excellent price. Thank you Jared for bringing it back into perspective. It just seems that a few extra scribes wouldn't have broken the bank. We all seek perfection regardless of the realities.

Then she couldn't button her pants...

It's not overall design flaws but ignorance to little details that make Red lens ownership a rocky road.

Devil IS in the details.

139mm threads? Really? (referring to the 17-50 pro zoom. 1mm off of being useful)

Do the RPP's travel much through a rack focus? I am trying to find the answer here but can't locate a thread.

Thanks,

Mike

What do you mean by that question? Do you mean, does the lens barrel expand forward? Does it breath? Or does the travel on the barrel go far (the amount you have to turn the barrel to focus)?

Matt,

Thanks for the clarifying question. What I want to know is if the lens barrels of the RPP's expand forward?

I'm trying out the Schneider Cine-Xanars and the 95mm expands about an inch when I rack the focus from one extream to the other. My matte box can not work with that kind of expansion if I use the pola in the bellows and my BarTech follow focus barely holds it through the rack.

I'm shooting a short with them tomorrow so I'll have a better idea how they work in "real life" then but the barrel expansion is a significant issue so far.

As the RPP's are another set I'm considering I wondered if they had this issue as well.

Thanks,

Mike

The RPP's were designed to hide any expanding that they do. They always stay the same length. If you look at some of them as you change focal distance, you will see inside the housing the front element moving though.

Very VERY thankful that RED designed them this way. Expanding lenses are about the dumbest design I've seen for cine gear. If you aren't using a mattebox it's no biggie, but when was the last time you didn't use a mattebox with your RED?

It is a cheaper way to make the mechanism, though. And many matteboxes have enough play in the bellows to make it work (at least for normal focus pulls, you generally aren't pulling end to end on any lens).
