Hoya ProND is my choice for circular IRND filters, & own sets in 58mm, 62mm, 67mm, 72mm, & 77mm. They use ACCU-ND ”electrolytic coating to deposit rare earth metals onto the glass surface to create hyper neutral density filters that have industry-leading virtually zero color shift and IR suppression. The deposit method holds neutrality that is free of color shift over time”.

The ProND(s) were the darlings of BMCuser at one point because of their IR suppression, & it’s good to hear they appear to work well with the P4K.

There’s no denying the P6K can suffer IR contamination as demonstrated in the that test, & I’m surprised there are not more thorough test available, but that may be due to the camera being so new. I suspect that using a IR filter is best practice even when no ND is attached, just as it is with the Mini Pro, but would love to see a proper test that proves that it’s not.
PS: ACCU-ND is Hoya/Tokina’s name for this tech, but there are some other companies that use similar metallic coatings.

My circular filters larger than 77mm are Firecrest(s), though if I was buying new today they’d be the Tokina ACCU-ND just for consistency across my sets. Also considering Tokina’s square, & rectangular, IRND filters.

Yeah, that I agree with. It's too wide, and I don't see a good reason for that other than to incorporate the monitor with minimum manufacturing costs. I think it's also designed partly to appeal to dSLR users, so maybe it's a BMD's way of enticing people shooting with mirrorless hybrids over?
Can't argue with that!
The video was not about IR that people hardly notice, it was grotesque and horribly prominent in a way that no one could miss. I want to see someone reproduce that, not innuendo.
They will need to shoot in afternoon sunlight or indoors under tungsten lights, and use plain-jane 4+ stop ND filters with no IR filtering. ( I also use the Hoya Pro ND filters that filter out IR contamination )

Looks like Tilta is now providing a kit for users to install/modify an articulating screen for $329:
https://www.newsshooter.com/2019/09/17/tilta-screen-modification-for-the-bmpcc-6k-4k/
"The kit is user installed and doesn’t require you to make any permanent changes to the camera. You can easily put the screen back to its original configuration if you want to."
"Not only does the kit allow the screen to articulate Tilta has reversed the USB-C input so a M2 drive can be installed in the space where the monitor used to be."

Wow this is pretty interesting. I’d be pretty terrified to modify it myself but if it’s coming from Tilta, I’d assume it’s not too too too risky.
I received my Canon EFS 17-55 IS USM F2.8 lens yesterday as pictured earlier in the thread. What a great fit for the P6K! You can read the lens reviews online, they are all pretty excellent but in addition, the auto focus and especially the OIS are exceptional for my P6K, 3 stops and you can notice the smoothness, not jumpy, doesn't jerk around. I get nicely hand holdable ergos and no micro-jitters in the footage. The lens is not new, optically it has sharp, L quality ED glass elements with good color, but with a sturdy plastic barrel and no sealing. The lens barrel does extend but does not wobble from side to side at all. Heft, feel and control is really nice, with smooth fully manual zoom and focus. Auto focus motor is not silent but is fast and quiet. The F2.8 aperture is constant throughout the zoom range. I haven't seen any vignetting in 16x9, 6K footage fully resolved from wide to tele, corner to corner, one of the sharpest Canon lenses around at any price, makes P6K shine. The only flaw on P6K is it is not parfocal, probably because of the flange mounting difference between the EF full frame mount and APS-C EFS mount. It's not wildly out of focus when you zoom but you should not expect continuous zoom performance.

^ The focal flange distance of EF and EF-S is identical: it's the same mount. It's just that photography lenses are not parfocal in general: even if some people say theirs is parfocal, if the design is not tuned to make sure that's the case, there will be copy-to-copy variation in terms of how parfocal the lens is. And yes, sure, I was completely surprised by this.

You don't need the USB for that if you can plug an internal M2 SSD, which this mod allows. But, as somebody noticed on bmcuser, you need the USB port for updating your firmware.

I've had my copy for a couple of years now, it's a nice lens.
1. Be ready for internal dust, I already have two nice chunks inside on top of the main element. If you're gutsy, you can YouTube how to disassemble the lens and clean it yourself or you gotta send it back to Canon or an authorzied repair center. It is the least dustproof zoom I own and I own several.
2. How is your manual focus ring? Mine sucks, it's crunchy and rough, I have a feeling also because of this lens' poor to non-existent dust sealing. I have taken mine to the Sahara Desert and have been in some mild sand storms and some shooting at the beach too, so its not surprising.
3. Try shooting handheld with AF and a mic on your camera. Mine has such noisy focusing, it makes this a challenge. Not sure if it's just my copy or if all of the EF S 17-55s are this noisy on focusing?
Optically, it's a very good lens. Build quality? I would have preferred to have paid $200.00 more for real dust sealing and the same build quality as my EF 24-105mm f/4.0 IS II. The 17-55 is just not a very well built lens overall. I'd pay double for it as an L lens with the latest STM/USM and IS II. I'd love it as a
little brother to my EF 70-200 f/2.8 IS II. Built to the same standards, I'd pony up $1,500.00 for it no problem.
At his time my manual focus ring is smooth, but I have no illusions about it. I sold my EF 24-105L F/4.0 IS first generation Canon lens years ago. Hated how the lens barrel extended downward under its own weight, the barrel distortion at 24mm, the softness at 105mm, the build quality was great. Would not be wide enough for S-35 even if I had it.
I have a Sigma 50mm HSM DG F/1.4 prime that has the crunchy focus ring. I need to send it for service.
