Please dub all of Chris' parts from now on. I am enthralled.

[@niccollsvideo]

Doing that ADR was brutal. If we make Italian westerns we can overdub, otherwise never again.

[@kaneclements7761]

@@niccollsvideo Italian Westerns! Yay. I can just imagine you wearing a stetson, chewing on a cigar and squaring up against Tony 'The Kid' Northrup outside the saloon, to see who was fastest. I reckon Northrup would be in line for a wooden overcoat.

[@ltlbuddha]

@@niccollsvideo You should write two different scripts with the same information and then dub. That way it will be easier to do and still entertaining.

[@LE672AJ]

Seriously. I’m imagining James Earl Jones himself coming in to lay down some Vader Mufasa vocal action.

[@SamTaylors]

I want an episode of full overdub but with the voices switched. Chris’s voice coming out from Jordan’s head - Jordan’s voice coming out from under that hair. You should offer that as the reward for getting to 350k subs by the end of the year 🤪

[@FTropper]

The overdubbing is hilarious :D Next time Jordan should overdub Chris and vice versa. ;-)

[@user-vy8jn9mc6g]

That was like hello from the 80s ))

[@LE672AJ]

Love that idea 😂. Make it happen guys!

[@grimacemcccheese]

Omg do it!!

[@AlanHoey86]

2010 era KZbin audio quality is my jam.

[@scottgmaclean]

Pentax... not the camera we want, but the camera we deserve. Remember, we asked for this...

[@wildbikerbill6530]

Pentax made a variety of decisions that made the camera less than it could of been: 1. Even working within the confines of AVCHD, where Pentax could of encoded at ~25Mbps, they top out at ~20-21 Mbps. This has obvious consequences in image sharpness/detail. 2. The K-01 does record PCM audio, to bad the sample rate is 32 Khz. What were they thinking? Were they thinking? It would be nice to know who pulled that one out of their backside. 3. Attaching an external HDMI screen auto-switches the camera into playback mode. So you have no way of working around the lack of an EVF with an external monitor. Be aware the rear LCD screen is low resolution and very hard to see in sunlight. Please note all three of the above issues have to do with Firmware/Software decisions, not hardware.

[@TheFraziers]

I’m genuinely shocked at how good the video quality was and how well Chris did with his voice dubbing. It was pretty convincing.

[@petouser]

why would the image quality be not good? pentax makes decent cameras with good sensors. you probably shouldn't expect the best autofocus.

[@Energine1]

Weed be legal here too breh 👍😉

[@TheFraziers]

@@petouser good image quality for stills doesn’t always translate to good video image quality. A camera needs good bit and data rates in addition to a quality sensor

[@johanleoste6308]

The pentax quality combined with the audio really reminded me of your old videos from the Camera Store days. Keep up the good work!

[@richards1243]

You two are by far my fav on KZbin for camera related videos. How you don't have 3M+ subs is beyond me. Thank you for doing what you do

[@Fedor_Dokuchaev_Color]

Wow! Pentax footage looks great. Very stylish. Soft, but with a distinct feel. Good job, Jordan!

[@nastycooperation9901]

Switch to the Pentax! The Audio is really oldschol youtube

[@justincooper7015]

That was the best. The reviews are always great, but the dubbing was so good.

[@thomasneedham3342]

Lockdown here in the uk....I have been so looking forward to the K-01 episodes!

[@TL-vt8uk]

The K-01 did amazing!! This may need to be DP Review TV’s video camera of choice from now on! As payback, it may be time for a vintage 35mm focal length shootout for Chris!!

[@colhutchins]

Probably the best footage you've ever shot. What camera is that Jordan? :-)

[@killian2826]

Pretty sure that it is the Sony A7R III as we can see the name at 8:20 in the top corner right

[@TimothyGordon]

@@killian2826 did you feel that go over your head??

[@NicJohnson]

I'm gonna say it. The Pentax wasn't that bad. Hats off to Jordan.

[@kaimelis]

I'm gonna say it as well. Pentax sucked more than a black hole inside a black hole.

[@PiDsPagePrototypes]

@Nic - It can do better then this.

[@user-jt6xh2ln9z]

Yeah, nah, it sucked.

[@petouser]

@@kaimelis what makes it so bad?

[@danieldougan269]

​@petouser Jordan explained the problems with this camera in a subsequent episode. In summary: - The image is soft yet oversharpened - The dynamic range is extremely small, so it takes a lot more work with lighting to shoot it outdoors - The IBIS is useless - You can only use lenses wide open - No headphone jack or audio level display (which reared its ugly head here with the audio clipping) Pros like Jordan can compensate for many of those shortcomings, particularly by artificially lighting a scene, but it's definitely a pain in the ass.

[@shlawchablaas]

The lens looks fine and all, but what this episode really convinced me about is that getting a Pentax would be fun. I’m sure a lot of people besides myself would be VERY interested in a little behind-the-scenes discussing which lenses you are using on the K-01, as well as what post production is like compared to the S1H. For me, the most noticeable improvement in video tech in the past decade has had to do with how much more easily my computer can handle video footage-it used to struggle adding effects to a 5D II in 1080p, now a similar level MacBook can zoom through 4k with no stutters or setbacks. I imagine that for that reason, post production on the Pentax must be so much better than it used to feel circa 2012.

[@parshua]

Interesting! As long as the audio was bad, I was noticing the Pentax's low quality video. 10 seconds after the sound was fixed, I completely forgot about it.

[@mrnessss]

You guys are putting out INCREDIBLE content! 🙏🙏🙏

[@BigJohnnyMoe]

Yep. The Pentax image quality looks fine to my eye, at least for YT. Please do this with a Pentax Q when you guys reach 400,000!

[@mics1377]

I'm so glad you guys got to 300K just so Jordan suffers by filming with a Pentax

[@jackslayer9418]

Literally just watched the live stream from sigma haha. Nice work guys

[@yoga7788]

Hi Chris, just watched this review and your concluding comments where taken on board. The two lenses reviewed were pretty good but I decided to go with Sigma 24-70 2.8. thanks excellent review.

[@JennyDarukat]

This is the kind of lens that might yet tempt me back into full frame.. I don't need absolute razor sharpness in a zoom and these results still look well-acceptable for my personal use, so I'd gladly pick this over a 24-70 2.8's extra bulk even at a bit of a compromise.

[@travissmarion]

Honestly I just want a side by side comparison with the Tamron 28-75 F2.8. P.S. I love the improvisation for the audio issues.

[@HendrikMorkel]

This Iron Chef dub is something which every future Episode should have. It's an instant Classic, this Video!

[@markaustin614]

This is the best...excellent effort!!!

[@PKWModelwerx]

Hilarious plus an excellent and thorough review. Thanks!

The Pentax quality is actually better than I remember! Should we expect another attempt at a BMD Ursa 12K video?

[@Indrakusuma_a]

We were only expecting visual change, but they give us bonus on audio change as well xD Love how Jordan uses Jurassic Park font styling to let you know it's 'ancient' ;D

Video quality on that Pentax not as horrible as I had expected. The overdubbing just made me realize how fast Chris talks

[@EscapeSquad]

Love this youtube duo!!!!amazing videos very funny and awesome to watch! who the hell is gona buy this lens instead of the sigma 24-70 or the tamron ?

[@kollege305]

Filmed with Pentax, video watchable in 4k. Gotta love it. 😁

[@triplestrafe]

the dubbing was actually quite refreshing :)

[@techlessYT]

Another great demonstration that you can get away with a bad picture quality but not with bad audio...

[@heaps.]

That dub work was solid 👌

[@CallMeChato]

Reviewing this on my Apple Watch, the video looked great. At 1080p you can tell it's not very sharp, mushy details and lots of digital sharpening on the edges, was that the camera or post? Colours looked good enough. I'll bet most people would be focusing on the story and the quality from the reviewed product and not the output from the Pentax. From that perspective it worked just fine.

[@martinhinge1462]

You did a really nice job with what you had, Jordan. Yes, it's soft, but you make the best of it. 😁

[@siyu4869]

K01's image quality is still great, and Chris and Jordan's skill on audio dubbing is amazing. Can you please do a small interview and let Jordan talk about his experience with K01 after these episodes? :p

[@HappyHubris]

Am I the only one who didn't notice much of a difference in the video? This review would be far, far better with some comparison shots to the Tamron and larger Sigma as well as laying out the trade-offs: weather sealing, weight, magnification, etc. Honestly this was very light on information for someone to make a decision on.

[@tsprouse1322]

I have to ask was that 28mm and 70mm edge curve test done with internal camera correction on? Has Sony or adobe put out the camera corrections and the Lightroom corrections yet?

[@stefpix]

So is the Tamron better overall apart the busier bokeh?

[@JohnDennery]

I'm all about smaller and lighter lenses but so far it really seems like this is Sigma's weakest performing lens. I was hoping this would be the perfect lens for my A7c but I'm not convinced that this has the Sigma IQ I've come to expect! Great job with the dubbing btw - spot on!

[@RiceAndRun]

if the dub's aren't harder to implement please do it in every video. I love the 90's hong kong movie feel of the video !

[@travissmarion]

Yep. Exactly my thought process as well. I'm going with the Sigma 24-70 instead. Better performance.

[@louistangmusic]

[@gylfimagnusson6170]

The video actually looks pretty decent! Frankly hard to see any difference between it and previous videos. Full HD is plenty for KZbin videos. No doubt it though took more of an effort than with a modern camera. The audio was of course terrible - but it should not have been. I have shot video using either the internal microphone on a K-01 or an external one and the outcome was reasonable, far better than what they got. So there must be something wrong with this particular camera or some weird compatibility issue with the camera and the microphone.

[@gabrielmachadobsb]

Other than the glitch at 1:02 the Pentax looked quite decent!

[@logtothebase2]

Struggling to find prices for this, I think it has to be fairly inexpensive in order not to be tempted up to the 24 70 Art

Making me laugh .5 seconds into the review is always a win

[@martinsand5411]

The K-01 was a good camera with great image quality and a design that wasn’t for everyone. I happen to like it. Video quality was alright for 2012, which, as we can see here, is still fine for youtube. No, I can’t reach the green button either.

That Pentax K-01 looks better than I thought it would. But isn't it unfair that Jordan needs to shot with crappy stuff while Chris gets to play with the latest? I'd like to see Chris reviewing and shooting some old gear as well. Pick some of the cameras that stood out when they where released, both DSRLs and compacts and compare them to how far the development of digital imagery has come since the mid 90s.

[@mediabymarcopolo5890]

I agree that maybe that extra 200 is worth it for the 24-70 but I have been seeing a lot of stuff online about excessive dust getting in that 24-70 lens which leads me to stay away from it. I've seen it on tons of reviews on multiple websites and it is also on reddit as well with multiple users showing evidence of this being an issue with the lens.

[@luke.crafts]

This is basically where I am at. I would be content to deal with the extra weight in exchange for the extra features and improved sharpness but I'm not dropping €1100 on a lens I need to strip and self-service to remove dust, I don't want to deal with that. Also, while the 28-70mm is not weather sealed, the 24-70 sure as fuck isn't weather sealed very well if lots of dust is getting in after a matter of days in the case of some people I've seen.
