metabones does one but not sure it's greater than others.

https://www.bhphotovideo.com/c/product/1049207-REG/metabones_mbspfd_x_bm1_canon_fd_lens_to.html

i've read that they are working on new one but didn't find any real confirmation

Metabones confirmed in email communications that they are indeed working on smart EF-X speedbooster along with several other new products. Nothing imminent though expect a few months wait.

X-T3 V2.0 firmware details announced, available December:

https://www.fujirumors.com/fujifilm-announces-firmware-updates-for-fujifilm-gfx-50s-fujifilm-x-t3-and-fujifilm-x-h1/

Based on the X-T3 sensor IMX571 datasheet, it's an extremely versatile sensor, look at all these readout modes! (there are two more pages after this but it's about binned modes)

Interesting there's dual-gain ADC mode similar to ARRI ALEXA's ALEV III sensor, and the sensor can also operate in global shutter drive.

They where popular for Sony.

Because Sony use E mount for both FF and APS-C stills/cinema cameras.

A7RII/III have great quality S35 crop mode for video (and stills), but I rarely see people use speedbooster on them.

Well, some FF cameras have a better crop mode than FF mode in video, so one could shoot in crop mode and then gain back the FF FOV and an extra stop by using a speedbooster. 

Yes that's true. From a business standpoint, developing a speedbooster that only works in video doesn't seem viable.

Well. there are plenty of speed boosters for as small sensors as the m4/3, BMPCC s16 all the way down to Pentax Q. So Im sure they will sell just fine.

But those cover the whole sensor.

For speedboosters to cover FF sensor, medium format lenses is the only way to go.Insert other media

Its not only possible its already been done on Sony and Fuji. And I have confirmation several different focal reducers are in the making for the EOS-R as well as the Z6/7

Z6 has no crop in 4K, so I assume such focal reducers are meant to use with medium format lenses? If focal reducers only work in crop mode for video and have to be removed for stills I doubt they are commercially viable.

If the sensor is 36mm wide and there's a 1.75 crop on 4K doesn't that make it a 21mm wide chip which is only about 12 percent smaller than a super 35mm chip. Am I missing something? 

You're correct. The cropped area is between APS-C and M4/3.

This pixel shift Hi Res mode only works if the subject is absolutely static i.e. no leaves moving on the trees. I's a rather limited novelty feature that can't be improved on without a radical increase in sensor read out speed.

EM-1X takes it a step further, it now works when handheld and the subject only need to be reasonably still (works for portraits), a la Google Pixel 3.

I am thinking its not a 40mp sensor, rather it has a mode that stitches several photos together to get 40mp. I think the G9 has a mode that does something like this.

40mp would be interesting though but not any good in low light. 

The high-res mode produces 80MP images, and it works even when handheld, at 1/60s.

FT5 seems high the probability to see it around in the beginning of the year. If it will add 4K/60p with reasonable bit rate, IBIS? I will surely buy one. MFT glass attracts me.

It has all that and more.

My source told me EM-1X has a 40MP sensor and obliterates X-T3 in terms of spec and feature set.

Could you share the data sheet. The 11bit bit seems pretty kickass. 

Why do you think 11bit ADC is kickass? It's a quality compromise for readout speed. X-T3 sensor IMX571 operates at 12bit in video mode.

IMX461AQR-C_DataSheet(0.4.0)_171121.pdf

Apparently the X-T3 sensor IMX571 is so versatile and cost-effective, Canon will use it on a new APS-C camera (most likely mirrorless).

From GFX100S sensor IMX461 datasheet, the 4K readout is derived from 3884x2912 weighted 3x3 binning using 11bit ADC on the full sensor, maximum frame rate is 30.5fps, rolling shutter is 30ms. The sensor is also capable of line skipped FHD at 60p, HD at 120p.

WTH is that?! LOL Detail. Focus on detail and that's all... : -)

You're confusing detail with sharpness, there's absolutely no difference in resolved detail between the two, sharpness can be added in post with far more control. It cannot be removed if it's baked in.

Don't agree - if the filter density is lower it's intensity is also lower and thus it's ability to measure actual colour as it's determining the hue values by the differences in signal between the R G B The problem manufacturers face is that higher density CFA's reduce exposure and thus low light ability of the sensor so they trade these off against each other. They in effect give you just enough colour information to keep the average user happy.....  

What you are discussing here is called Quantum Efficiency, current APS-C/FF sensors can easily achieve 50%-60% QE, so around 1 photographic stop loss of exposure, similar to how our retina respond to light.

So auto focus test from Max, for me z7 is best in this test. That's so great that Nikon who was dead last is at least for me, the best now. Again for the test, many strange thing, because it is the Sony and Canon who are the greenish skintone, he did use auto white balance this time. Another thing of note is it is the Fuji which looks super soft, much softer than the Canon.

So, colour wise, instead of turning that guy into a zombie, Z7 whitewashed him this time...

I believe the P4P does 4k60p, while the M2 does not. That's something I prefer. But IMO the P4P image is more detailed and its cleaner at higher ISO's. Its also a wider FOV that I prefer. Lastly motion looks better on the P4P. Attached are a couple samples showing better IQ with the P4P.

I like the larger controller as well and the price difference is minimal. Since I'm getting paid to become licensed and fly a drone, I'm going with the lightly better IQ with the P4P.

Chris

4K60P on P4P is upscaled from 2.7K readout.

P4P does not resolve more detail than M2P, the strong edge enhancement halo creates a perceived increase in sharpness.

10bit on M2P means complete absence of banding.

to the lucky ones that have this camera, is there a big difference between the internal 420 and the external 422 ?

 

Actually there are two aspects to consider for external recording:

1. 422 instead of 420. 422 is beneficial for intense colour manipulation and/or VFX such as keying and compositing.

2. Minimal compression with robust codec such as ProRes/DNxHR. It's very easy to edit/playback in real time. Image quality wise, the difference between external recording and internal 400Mbps HEVC ALL-I is minimal in low to mid ISO. In higher ISO settings combined with low key lighting and/or high detail scenes, H.264/HEVC tend to break apart and shows more blotchness. ProRes HQ/DNxHR HQX are able to retain fine noise patterns for easy clean up in post.

Hahaha, couldn’t care less, I use an external monitor anyways. 

That’s what I am talking about. Somebody needs to come up with dual strap solution so one can rest his hands from time to time. On a long day shoots that kind of feature would be invaluable.

It's called an Easyrig

Some color grading to  test the H265 10bits codec :

Very strong codec  (but a few moiré on the pullover).

https://vimeo.com/299173698

You should have tested in 4K. the 1080p mode on X-T3 (and on most cameras these days) is not supersampled. It's a combination of line-skipping and pixel-binning, hence the heavy moire.

Ah I understand now, I went through some of images and videos you posted, I agree you totally made the right decision returning everything, as X-T3 doesn't deserve you, neither does 1DX II.

They are made in China now rather than Japan so I wonder if that has something to do with it

Most of the consumer electronics products are assembled in China, including those more sophisticated than mirrorless cameras. So no, it has nothing to do with the change in country of origin.

It could be that very early production batch had rare issue that slipped through QC, this happens all the time in electronics manufacturing.

For 400 mbps recording, I made the mistake of buying 128GB cards rated V30. I can record but when I try to playback the files in camera, I get a read error. When I play the files on the computer, they are fine. When I record to 200 mbps, playback is fine in the camera.

I think it only records fine because the camera has a large buffer (for 30fps stills shooting).

Noticed a strange phenomenon today, when using the touchscreen to pull focus in video during recording, in AF-S mode, a touch would only half focus on the subject (focusing starts slowly and stops midway). In AF-C mode it works wonderfully though, locks dead on almost every time. But AF-C focuses everywhere the focus box goes and does not offer much control vs. AF-S.

Anyone experiencing the same?

Of all the X-T3s sold so far this is the first failure report I've heard of, definitely rare and isolated incident.

iPhones have exploded in the past, I must say they are not safe to use.

Lovely example of the out of camera colour. Personally I much prefer the natural look to the LUTs which have been thrown onto the footage. I'm sick of seeing M31 and Deluts personally. It makes all cameras look the same, which is perhaps the point.

The ease with which you can obtain a pleasing, cinematic yet naturalistic look is what separates the men from the boys, in my personal opinion. It's why we all love Canon colours, Alexa, Blackmagic, and now Fuji.

Breathtaking shots! What's the DR setting? Have you touched the shadow/highlight tone, sharpness and NR setting?
