Looks like green screen to me.

I shoot all kinds of stuff. Tell me what sucks. vimeo.com/310480543/dfd36479a4

Thanks for the knowledge Dom! Very helpful. I shoot on all sorts of cams from Red to Blackmagic to DSLR (even GH5S w/ Speed Booster)... so it's hard to say what these lenses might live on regularly. I didn't realize there was as much variation in sensor-to-flange depth between different cams; figured it was a tight spec. So when you rent a camera and a set of lenses from a rental house, you may or may not have focus marks that line up? I guess the lenses can be adjusted on the spot by a technician prior to the whole package going out?

I just bought a used set of cine primes (Canon CN-E 14, 24, 35, 50, 85, and 135) from LensAuthority.com. These are the first cine lenses I've owned. I've been playing around with these and think they may need some calibration, but am not sure. How accurate are the focus distance scales supposed to be? I've heard very accurate... which makes me think these are off. With the camera stationary, I am measuring from the sensor plane to a point in focus directly in front of the lens, and I'm finding the focus markings on the lenses to be off, sometimes by a few inches. The 50 seems to be dead on though. Is it common for cine primes to go out of 'calibration'? Is it something that can be corrected? I'm a CPS Platinum member and am thinking about sending them in to be looked at, but figured I'd ask around first. The lenses were advertised as being in 'excellent' condition, and they appear so - the glass is flawless, and the housings show no dents, dings, scrapes, or other signs of abuse. Being new to cine lenses, I guess I'm just not sure what to expect. Perhaps I'm not even testing them correctly. Any insight or advice is appreciated!

Thanks for your thoughts Brian. I won't worry about the bulb orientation until there's further evidence to then. As for the worm-gear drive in the heads, I went ahead and sprayed a tiny bit of grease on em. They instantly quieted down. I tried to be very sparse on the grease - certainly don't want it catching fire or whatever.

I have an Arri M18 and M8. Can someone tell me as a matter of fact whether the bulbs are supposed to be installed with the internal bar/rod up or down? Secondly, is it okay for the ceramic base to be cracked? I just noticed this upon close inspection. And thirdly, is it okay to spray a tiny bit of lithium grease on the rails inside the housing? I'm trying to kill the squeaking when adjusting the focus knob.

I ended up buying the M8 not long after starting this thread. I love it. It may not be quite as versatile as a Joker, but it is a tank and light quality excellent (just like my M18). No case kinda sucks but not really a deal breaker. Very happy with it.

Whoops, my mistake, I accidentally posted this in the wrong section. Sorry. Mod, please delete this.

I'm an owner-operator videographer/DP about to spring for an M8 to compliment my M18. I've noticed the M18 is a popular rental item and common to see on your average production. I've yet to see an M8 on set though. Nor can I find ANY information or reviews online. Why is that? No love for the "little blinder"? Maybe it's because the M8 is fairly new? A year and a half old or so, I think? I still would've thought there'd be some talk about it. Anyway, let me know what ya'll think about the M8. I love my M18 and don't see why the M8 would disappoint. I'm about to pull the trigger but wanted to see what people think.

I recently bought an Arri M18 and got it up and running today. This thing is a punchy beast! Though one question I have is: Can I change the "flicker free" switch to "50 hz" or 60 hz" while the light is on? Figured I'd ask before I fry it. Thanks!

Selling my DP6. Its essentially brand new. Check it out> http://www.ebay.com/itm/SmallHD-DP6-HDMI-SDI-Field-Monitor-LP-E6-Battery-Mount-PRISTINE-/111259437660?pt=LH_DefaultDomain_0&hash=item19e7944a5c
