FuhTeng: I'm excited for the RX10 III - what a fun camera to rent for a vacation! Sure, it's expensive, but it's a 600 mm f4 lens! I just hope the AF is up to the task.

And if it's not, the Nikon DL24-500 sounds great too.

You mean it's 600 f/10.8. You can't quote FF equivalent FL and not FF equivalent aperture. The 1" sensor is a 2.7x crop format.

Boissez: Lackluster AF, build and a lackluster sensor (although DR is improved). Will Canon ever release a compelling midrange product like they used to in the XXD series?

Such a shame.

Lackluster reply from someone that has probably never used a Canon camera in their life and spends all day on forums talking about DR rather than mastering their craft. Easy to blame the tools for shoddy work.

caravan: The D500 looks good but behold the a6300! Amazing.

The results are so close it's not even worth worrying about. The headline should be, you don't have to worry about IQ on the D500", AF performance will be the main reason you'd buy this camera and that has yet to be demonstrated.

Link | Posted on Apr 27, 2016 at 02:57 UTC

The gushing enthusiasm about the high ISO performance is ridiculous. The D500 is barely better than the a6300 or D7200 at 25600 and if those sensors were down-sampled to 21MP the results would be even closer. Nikon has not altered quantum physics and have only barely raised the bar. You certainly would not use ISO 51K or higher which are marketing cr@p. The really good news is that they have not made the mistake they did with the D5 and the sensor has impressive DR and is ISOless, the exact opposite of the D5, which has gone markedly backward. However yet again the D500 is only performing a wee bit better than the D7200 in the DR and ISO'lessness testing.

Leaving aside the sensor the real drawcard of this camera is the AF. And could they have just used the D7200 sensor in the D500 body and would anybody really see the difference in IQ.

Max Iso: Easily the best crop sensor camera ever made. Best IQ, best battery life, best AF, best feature set, and Nikons great lenses backing it up.

ALL HAIL THE KING !!!!!!!!!

Easily the silliest post ever. All hail the fanboy!

In reply to:

Jonath: Would be interesting to see some kind of DPR comparison / test of grad filters vs ISO invariant sensors to see what is possible and how big a difference they make, also factoring in the effort required to get the best results. Maybe even some kind of quiz to see if DPR readers can guess which used grads and which not, to my mind modern sensors will make the results increasingly difficult to distinguish.

Well if dpreview levied a tax on Sony trolls they would get rich very quickly.

Jorginho: And so m43s just keeps developping and developping. These are not huge steps, but the stabilsed video in 4K is a very welcome and huge step for videographers. Shuttershock: I guess it is true it happens but on my GH4 it is veyr rare.

This also holds a lot of promise for the GH5. 20 MP, 5 axis stabilsation in video, no shuttershockI bet that Leica EVF (or something similar) will be in it.
And with 5 axis something like HiRES might be on the drawingboard but I guess not in the GH5.

I wonder how well this all works with the 100-400 Panaleica (stabilisation)...

GX80/85: a very nice addition to the ever growing familly.

Except the sensor, barely any change in 3-4 years. Pls get Sony/Toshiba to produce your sensors and then your cameras go from great to awesome.

In reply to:

brendon1000: This camera seems to truly showcase the potential of mirrorless cameras. As much as I like Sony FE system it doesn't have any real size advantage once lenses are considered.

This Panasonic is a truly small camera and has many lightweight small lenses to match the small body.

FF mirrorless makes little sense from a size and weight PoV. Let's face it if Canon had of updated their sensors 3 years ago, the noise about Sony would be much less. Miiroless m4/3 and APS-C makes a lot more sense. Alas m4/3 is barely moving the goal posts on the sensor front. Maybe they should ask Toshiba to make their sensors given how good the D7200 sensor performs.

I suspect this 16MP sensor sans AA filter will resolve similar to the 20MP sensor in the GX8 which offers little improvement over the current 16MP sensors.

In reply to:

Contra Mundum: All those super high ISOs are pretty useless from my perspective. Maybe somebody can use them for small web images, but most people wouldn't care. Even 16000 ISO looks terrible with noise and poor dynamic range.

Manufacturers should better concentrate efforts on making decent 12800, so far none of the FF cameras have anything highly usable above ISO 6400. Instead, they all compete who looks less terrible at ISO 100000.

I think it must jsut be you. While I agree that above 32000 things go south fast, at least to ISO 25600 it should be very usable. Heck my 1DX produces excellent results to ISO 12800 and very usable results to 25600 and this should be a bit better.

Don't rely on dpreview images or processing to be your sole source of information.

In reply to:

matthew saville: Well I guess you can't have high ISO cake whilst eating some dynamic range cake too, ehh?

Still a tad better than Canon's best FF offering, until the 1DX 2 results come out, maybe.

Sorry Rishi you can't have your cake and eat it too.

NeilBart: The Canon 80D looks a good package for both imaging and video. Check out the banding with the Nikon D7100 on these settings! Why didn't Nikon fix that with a firmware update?

Sorry Dougbm_24 Nikon is still using Toshiba for the D7200, just a much better sensor than the D7100 and the king of the APS-C sensors, including anything form Sony.

bmwzimmer: Canon Crop Sensors are 1.6X vs everyone else which is 1.5X. So its 6.3% smaller and will obviously not perform as well. Even it it were the same size, it's still a bit behind but it's at a point, the differences in real world shooting is negligible...

That just says your Canon friend needs to learn more about photography and not be so lazy. I wonder how we ever took good photos in contrasty situations without Sony,

In reply to:

photogeek: A7R2 runs circles around this, at about the same pixel density. Impressive feat on Sony's part. Back to the drawing board, Canon. Better luck next time.

Ah yes the good old Sony, I hope it doesn't break down on you so you won't discover their amateur aftermarket service.

I'll bet the 80D AF runs circles around your Sony. Back ti the drawing board Sony

In reply to:

aramgrg: Quite good! 1 stop better than predecessor. More importantly no purple hue. However, still not up to sony sensors.

1 stop, more like 2-3 stops. Previous sensor fell apart after a two stop push and even then it wasn't great.

Link | Posted on Mar 21, 2016 at 21:47 UTC

MAybe Canon traded of ultimate low ISO DR for better high ISO performance. It's always a juggling act and we've seen weakness in EXMOR at high ISO and certainly you wouldn't use it for astrophotography

Did they fix the useless colour profiles for Canon 5Ds(R), which are ridiculously overly contrasty. I'll bet not.

Nice video indeed, beautiful part of the world. Great to see a camera just being used at it should be, in the great outdoors and let's hope discussion isn't dragged down by Canon haters.

What was used to shoot the video of the G5X in use?

PKDanny: Does Canon and Nikon allow Sigma firmware in Canon/Nikon camera dslr? Others not allow.

Yes Olympus cameras can update lens firmware when connected to PC and running their software. Some newer Canon lenses allow you to update firmware.

In reply to:

Old Cameras: Well if you were thinking of buying the dock, now you have one more reason. It just became essential.

Oh boo hoo, you pay $1100 for a lens, same for a camera, and then you whinge about a $60 dock that not only allows you to update firmware but customise other settings of the lens such as OS, focus distance limit, MA, AF speed.

I suppose you put $10 filters on your lenses too.
