  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

ARRI LPL mount

Lenses like the new Arri Signature primes are LPL, so if you wanna give em a spin on DSMC, then you'll need this mount.
 
The Arri LF introduced an enlarged version of the PL mount ("LPL"), which is being used for all of their new Signature lenses. There is an adapter available to use PL lenses on an LPL mount, however, Arri evidently did not see a need to do the reverse on other cameras, like Red.

Question for Phil ... is this only used for VistaVision lenses. Why would we need this mount?

I heard the bell that I was summoned from my dirigible in the sky.

In short, good question. There is no real "need" of this mount, not for VistaVision or FF35. It was created by Arri and at the moment really only required if you are using LPL mount Arri Signature Primes.

interestingly the Arri LPL features a flange distance of 44mm, which is the same as Canon's EF Mount. Regularly PL is as we all know 52mm. The general concept with having a different mount like this pop up is the potential for what it could mean for optical design both for smaller faster lenses and even larger than VV formats. However, if there's room for my personal opinion, I think this is sort of a medium step with a flange distance such as this to produce compatibility across current camera systems. Which is fine.

What I truly want the industry to undertake in the next few years is a rugged short flange distance mount in the 20mm-ish range as that's where you'll see some real spicy optical benefits. Similar to the one stop gains of the recently announced Canon 28-70mm f/2.

That said there's a bazillion reasons not to do that today. And interestingly you can with a standard PL mount produce glass that covers well beyond VV without occlusion, but you're always working within a particular set of rules when it comes down to it.

So to the original question, why LPL? At the moment, only if you want to shoot with the Arri Signature Primes. Or for some reason if you are building your glass library up from scratch as a few manufacturers will eventually provide LPL mounts for a few of the popular lenses out there.

Thanks Phil, I feel better choosing PL lenses now. I knew you'd know.
 
Just to add to this thread regarding mounts and a great deal of new VistaVision, FF35, and even larger 65mm format lenses announced at IBC 2018, all of which are made for regular old tried and true PL Mount.

I'm not saying LPL is useless or anything, there is validity to it once designers truly exploit the possibilities.

But I think the true great beyond for digital cinema cameras will likely be in the next generation with a shorter flange distance even still. By about another 20mm give or take.
