wolf33d Posted August 27, 2015 Share Posted August 27, 2015 DxO tests the A7rII sensor: Is the new king of Full Frame (by a hair)Well amazing low-light and color depth. Low light was expected. Very disappointing DR, considering an APSC Nikon D7200 does better here, not to mention a very old D5200 (200$ camera) has the same DR. And D810 is a full stop better (huge...).By the way, I shot 2 weeks with a D5500 and I was surprised by the DR for an APSC sensor. I could get good pics from one exposure, unlike on 5DIII. For me DR is super important. Example of a D5500 shot with the trees at the botom that were completely 100% black (image was underexposed for the sky) completely recovered : https://500px.com/photo/116251089/star-over-assiniboine-by-loup-fsr Quote Link to comment Share on other sites More sharing options...

Since A7rII has the same DR as D5500 (and better color sensitivity) you will be able to capture the same quality of photos. DxO tests the A7rII sensor: Is the new king of Full Frame (by a hair)Well amazing low-light and color depth. Low light was expected. Very disappointing DR,Oh come on. Look at my previous comment. And D810 is a full stop better (huge...).For less than 1% of the users. For the other 99% the much better DR in high ISO and video will be more useful. You must have found the only point in the whole review that the A7rII performs very good and not great On that note, DXO does not test long exposures, where the DR of A7RII appears to suffer the most.

Julian Posted August 27, 2015 Share Posted August 27, 2015 The D810 has higher dynamic range because it has iso 64. At iso 100 it's 13,9 stops vs 14,36 stops. Look at the measurements tabs on DxO, not just the scores.The A7R II has much better DR at higher iso values. Quote Link to comment Share on other sites More sharing options...
wolf33d Posted August 28, 2015 Author Share Posted August 28, 2015 Better DR at higher ISO value... LOL this was the argument of canon for years saying there sensor is better than the Sony one. Otherwise for the first comment above, yes I agree 13.9 is enough in real life. But when you pay 3200 in the last camera you are sad to get one stop less than D810, obviously. And as you mentioned the worst is with long exposure.... And don't get me wrong, A7RII is an awesome camera. I have the feeling 3200 is not the right price considering those quirks..2500 certainly.

TheRenaissanceMan Posted August 28, 2015 Share Posted August 28, 2015 For the other 99% the much better...video will be more useful. Have you seen the video out of the D810? Not to mention it doesn't melt into a puddle if you record for more than 10 minutes. Shield3 1 Quote Link to comment Share on other sites More sharing options...

With the FLAT profile, you get pretty much all that DR on the D810. Maybe you lose a stop, but you also have great colors to work with. Meanwhile, the A7R II has shut down due to overheating.

I have no doubt that D810 is a great camera and quite likely the colors will look better out of the box when compared to the A7rII, but what's your point?

That this test from DXO Mark, combined with the A7R II's well-documented overheating problem, proves to me that there's little reason to choose it over the D810 for hybrid shooting. It takes equal or better stills, has a much better lens library, offers more robust professional and third party support, is more reliable with long recordings, has a much better battery life, and gives you comparable DR with better colors. Oh, and it's $200 cheaper. Besides 4K and the EVF, I don't see a lot that points in the A7R II's favor unless you just can't cum without 4K.

Where did I say that someone should buy the A7rII over the D810? Buy whatever works for you best. I am pretty sure each one has its own needs/wants. Keep in mind that DXO compares just sensors and digital processing. Cameras are much more than that. Please look again and you will see that the whole conversation was just on numbers...

You compared the two and concluded that those interested in shooting video as well as stills would find the A7R II more useful. I was providing a counterpoint. Again, A7RII during HD recording does not overheat.The A7R II also doesn't stack up to the D810 in HD mode. You have to downsample its 4K to get comparable results...and 4K overheats the camera in 10 minutes. Quote Link to comment Share on other sites More sharing options...
Don Kotlos Posted August 28, 2015 Share Posted August 28, 2015 I mentioned a whole slew of other factors besides just numbers, actually.Yeah, I know. My point was "Relax we were just comparing some numbers and not the cameras as a whole package" You compared the two and concluded that those interested in shooting video as well as stills would find the A7R II more useful. I was providing a counterpoint. Nope. Never did that. The A7R II also doesn't stack up to the D810 in HD mode. You have to downsample its 4K to get comparable results...It could very well be the case, I never claimed otherwise. But if you have evidence of this I am sure a lot of people would be interested to see it. and 4K overheats the camera in 10 minutes.Well now its getting silly. Enough with this gearheaded fights.

My point was "Relax we were just comparing some numbers and not the cameras as a whole package" I'm plenty relaxed, but you seem to have some problem with the comparison. Can't I discuss how they compare both in numbers and as a whole package?It could very well be the case, I never claimed otherwise. I didn't say you claimed otherwise. I just put forth the information. Why do you take everything I say as an attack?Well now its getting silly. Enough with this gearheaded fights. I wasn't "fighting." You made a point. I disagreed, so for the sake of anyone who looks through this topic for information, I made a counterpoint. That's how discourse works.

Guest Ebrahim Saadawi Posted August 28, 2015 Share Posted August 28, 2015 5DS only shoot 7 stops DR 30P 1080 without LOG and pixel-banning，5Ds gives 11 stops of dynamic range in video mode at Neutral Picture style and an incredibly detailed HD image without any aliasing/moire just like full pixel readout sensors. I have no idea where 7 stops come from it's incorrect. Plus it has all that whilst being a camera not designed for video at all, even the company tells you so. D810 has about the same dynamic range as the C100 in Flat picture profile, around 12 stops, about a stops or 1.5 stops higher than Canon DSLRs, and the A7s has an extra stop of DR at S-LOG2 in the highlights but noisier shadows. Not as higher DR as you might think plus much better colours and reliability/durability. Try the D810 and A7s in Flat mode and you'll understand. Both have great video images, D810 being much better colours, much less rolling shutter and much more durable body and battery life and much better stills while the a7s has a stop higher DR in 3200 ISO SLOG2 plus the smaller body, better sensitivity and EVF. Both have incredibly sharp s35 crop modes and sharp FF modes without aliasing/moire and high dynamic range. And do people still read DXO? Even worse, on a video site? I thought we've passed that era.

Yes some people who do video also do photoYou thought wrongly. And if you passed this area and do not care at all about DxO, why did you bother clicking on a thread called "A7RII gets DxO marked", and even worse, comment on it?

Guest Ebrahim Saadawi Posted August 29, 2015 Share Posted August 29, 2015 Because I wanted to express my opinion about DXO as a source of image quality performance, with a little invention called ''sarcasm'', look it up. And as you may see people everywhere agree, but also many disagree, if you believe in DXO the power to you,but I'll come here and ''click'' on any DXO mark topic and 'comment' saying whatever I want about it, me and everyone who doesn't believe in it as a good source of information on image quality of cameras. That's what a forum is for. If I only searched for topics on things I like and spent all my time praising them my existence would have no value here.

Asmundma Posted August 29, 2015 Share Posted August 29, 2015 I really prefere the scalbility of Sony, you can go very light without the hassle of an extra EVF to shoot, as you need for Canon and Nikon DSLR. Put a bigger lense fe-28-135 ( get a range from 28 till 200 for video). Go with ShoGun if you stay in one location. Take amazing stills with the A7r2. It all about prefereses, but I am tired of dragging the big Canon + lenses around the world. If your sitting in front of your desk, many camreas looks nice on paper.

It all about prefereses, but I am tired of dragging the big Canon + lenses around the world. If your sitting in front of your desk, many camreas looks nice on paper. Agree with you. On a French forum a guy compared weight of A7R II + 5 usual lenses (35 1.4, 55 1.8, 70-200 ...) and compared with Canikon equivalent, and the total weight difference was only a few grams. Still, better gain a few grams than nothing I agree (at the expense of ergonomics..?) For me the biggest pbm with DSLR is the mirror and OVF and poor live view AF performance. Otherwise ergonomics is good, lenses are good (want cheap and light, take canon 50 1.8 for exemple, want expensive and big, take canon 50 1.2... Lots of choice) ..

Asmundma Posted September 4, 2015 Share Posted September 4, 2015 That's strange. To compare you have to take a 1DC to get 4k. The Fe 28-135 (gives 200 in S35 mode) add the FE 55 1.8 for low light. I have the canon 70-300 and the 1dx, this will be way more. So its wrong. The Fe 35 1.4 is heavy though. Batis 25 would be lighter. Quote Link to comment Share on other sites More sharing options...
