  • With the Sony A7R3 I have notice as an issue that they provide very poor knob options. It would be really useful to deactivate sound volume on image review. I go crazy to open this useless option on review all the time I use the wheel to review. Another I interesting option for a next firmware should be to cancel the review mode more faster for a better availability after review. Concerning menu you already notice that it's the worse to use but some improvement could simply add as option to change contextual for review who reset the position on shooting. Also when we work on key option, not to restart to the option 1 and to remain in sequence when one option is set. And in the end, what about global shutting? Any chance to get it one day?

  • Hi, Can you please compare between Sony a7 III and Sony a7RIV. Thanks.

  • I think a downsampled uncompressed raw function would be amazing. For example you are at a event and you're okay with "only 30mp" the raw files get downsampled, so you do not need so much space on your card i think it would be great. Even though i love working with big files they are not always needed but switching to jpg is a option i do not like

  • I'm not sure you can conclude that dynamic range is better if it appears the added detail is at the expense of color rendition. I'll wait for further tests and reviews for this one.

  • The Mark 4 looked worse noise/artifacts in dynamic range. Why'd he say 3 looked worse? Much more colored noise and off-color in Mark 4. The blacks of the 3 looked more black. The white looked more natural. I would say the Mark 4 simply has its noise spread out more evenly. Whereas the Mark 3 has not more clumps -- but its more clean around its fewer clumps, so it maybe can be individually more noticeable. I think he meant to say maybe that he finds the Mark 4's noise to be "more pleasing?" But how is it cleaner? Time @06:33 -- looks terrible!

  • My 7 year old d800 has too much resolution for almost everything, so I really can't imagine what this could be used for, aside from a few really specific applications.

    • @Tom Herriman dang Tom, why you gotta be so aggressively defending my choice of camera 😅? Cropping significantly and printing really large are things most photographers do very occasionally, if ever. (sure there are some exceptions, but I'm talking about most users.) My point is that if the d800's resolution is usually overkill, imagine how much moreso that would apply to a 61MP sensor. But I'm hardly attacking anyone who wants one, it's definitely cool. So maybe dial back the passive aggressive 'TH-vision Guy' and enjoy the video ;).

      Jason AndrewsJason Andrews18 วันที่ผ่านมา
    • @Jason Andrews your original comment says that your 800 has too much resolution for almost anything and that you could not imagine why anyone would need that much resolution. I guess that was before you knew about prints and cropping?

      Tom HerrimanTom Herriman18 วันที่ผ่านมา
    • @Tom Herriman it doesn't have too much resolution, it has too much resolution for most applications. For any digital viewing, and anything less than a massive print, a 24MP camera would look just as good, take up less file space, and be quicker to edit. All that said, I love my d800 because I like to crop, (sue me,) and I like the ability to easily make large prints. But for 99% of my images, 16-24MP would be just as good!

  • No Tony, you don't magically get better dynamic range out of your shots by shooting in compressed mode and throwing away data... You had it right the first time around and then you "corrected" yourself by saying the opposite. lol Also the Riii files looked significantly better to me when brought up by five stops, especially in terms of color noise. I have no idea if that's still true when shooting them at ISO 3200 vs bumping it up to that level in post, but it seems like something worth investigating.

  • I didn't understand your comparison of 14-bits to 15-stops dynamic range🤔 Isn't the 14-bits the granularity of the data where as the 15-stops is the range of the data or the ratio of the lowest to highest value in the range. So, let's say that my camera has an 8-bit ADC, I still can represent 30-stops or let's say 1000-stops of data. But I'll only be able to tag 256 values from the lowest to the highest value. Right?

  • 60mp is a great achievement, but the best Sony lenses max out around 45 MP in sharpness, at best aperture, at center of the frame. And there are just a few primes that are even that good. I also wonder how useful the pixel shift is going to be in real life, where 1 pix of camera movement (~0.0037mm or 0.00015”) over 16 frames will spoil the shot. I don’t think I’m trading in my A7riii just yet.

    Mark LewusMark Lewus23 วันที่ผ่านมา
  • The lens can’t resolve 240mp or 960mp? What does pixel shift have to do with the lens? The file isn’t even created in camera.

    Eric StadlerEric Stadler23 วันที่ผ่านมา
  • Little tip, you may want to try some better corrected lenses to show difference of sharpness and resolving power in a more accurate way. Each lens has its own comfort zone, meaning it performs its best within certain range of pixel density, which can be related to its MTF performance under different line pairs. A lens looks nice on 12MP FF does not necessarily mean it will perform as good on a 42MP FF, vice versa. Well corrected lenses, like Otus, or Loxia 25 / 85, has very balanced resolution on cameras with either higher or lower density of pixels. From a test I made with a tiny Nikon 1 J5 (1 inch sensor with 20MP), these lenses remain cutting edge even under an approx. 200MP FF equivalent pixel density. These are manual focusing lenses aim optical performance only, and they will really extract the power of high resolution cameras. While GM lenses, especially zoom lenses, are designed for multi-usage, where as resolution for extra high pixel density is not the priority. It need to balance between optical and zoom design, focusing speed and electronic solutions, price and manufactures, too much compromises are incorporated. GM zooms, put aside the QC concern and the strong color fringing that stick around all the way to f/8, are very much capable for lower resolution like 24MP FF. Some GM primes can really "satisfy" the a7R iv, which I think including 24/1.4. 85/1.4 GM is more suitable for 36-42MP. Of course sharpness is not everything for a lens, being extra sharp can even damage the look of a portrait. GM 85 is quite good enough in its own way. Nevertheless, for resolution test of cameras, I would recommend Loxia 25 and Loxia 85. Only need to remember stop them down when testing, they have some field curvature and vignette, also some chromatic aberration at wide open. Otus will be even better and easier for cross brand comparison, while being less easy to handle.

  • 12:04, is it also an issue on the Sony a9 sensor, probably the only CMOS sensor camera, having no rolling shutter on electronic shutter? - However: I wished sensor companies enhanced CCD technology, having no rolling shutter and banding by CCD technology itself. But no, all of them went “...the easy, tempting dark way...” of CMOS. - If you have a Leica M9, never sell it. Probably last CCD sensor Kodak made built in there. Above ISO 640, noise becomes horrible, but

I shoot Real Estate and believe me twilight shots need shadow pull and the 5DSR does great. Sucks you only compare Nikon and Sony in this. Just my opinion. Taken properly as images should be the EOS Canon 5DSR still makes killer natural looking images.

  • My entire raw catalogue thus far fits into 550gb on my Adobe 1tb plan. This camera would ruin that lol. I’m still using the A7s 1, but I’m definitely interested in the real time eye AF. If you’re saying maybe 20mp at ISO 3200, compare the detail vs A7iii at these higher ISOs? Rather than 4k60, or rather in addition to it, I’d be excited for a USBC output direct to SSD, like the Sigma Fp is doing

  • ISO EXPANSION is not “fake”. I find that comment deceptive. The camera takes a longer exposure (usually by a stop) and that more light/data is pulled into the raw file BEFORE the Raw file comes up in a raw converter. This has tremendous benefits!!! Because nearly half of all data is in the brightest stop or 2 of linear light (at capture) it potentially DOUBLES the quality of the data (lowering “fake” information known as NOISE). Any serious print maker knows how awesomely helpful it is and the results are not fake. Also, you might laugh but for a fine art printmaker (yes the minority) this pixel shifting quality is very exciting!!!

  • All this video and others confirms is we need to lobby Sony to release an A7RIIIa with the new grip, EVF and other ergonomic changes and just maybe a newer verison of the 42MP sensor with faster readout. Now more than ever I'm waiting for the A9II. I really find it bizarre Sony thought the A7RIII needed replacing inside two years when there are much higher priorities.

  • It's not too cheap. Tony if you worked out what the "manufacture" cost of the camera is, you'd be shocked. It's a sensor, some board/memory and a steadyshot mechanism. Manufacture time is way faster than a DSLR less calibration, less parts. What we're paying for is the advertising/marketing/freebies/trips etc ;-) No disrespect but these things cost not that much to make at all. They just don't sell that many - in comparison to years ago, margins are higher man

  • Interesting initial review. Nothing about this camera is earth shaking and at least nothing that shows it "kills" Nikon and Canon (Jesus, I hate statements like that). If anything, this camera could bite into the sales of Hasselblad's and Fuji's medium format market share. Giving folks medium format-like images out of a fullframe sensor. For hybrid video shooters, this is a no go as it offers nothing above what current competitors offer. In fact, it offers less video features. I'm sure there's a niche market for this, but as far as an everyday use camera for enthusiasts to semi-professionals (and even most professionals), I just don't see it's use that puts it above the a9 or even the a7RIII.

The ar7iv jpgs won’t be being converted correctly like they would be in Adobe once supported so noise will be being introduced vs looking at raw in photoshop.
