Ok this looks great for terrestrial subjects, so how is the coma for astrophotography?

Actually they'll be shipping in January

Brian Wadie: I've just used the bar chart to compare the EM-1 mk2 to the canon 1Dx mk2, there proximity of the bars for Performance surprised me, I know the EM-1 mk2 is going to be good but it shows it very close to the 1Dxmk2

That's my camera club bragging rights sorted! :D

Sorry what performance bars?

John Mason: Some thoughts .....

If people focus on ultimate image IQ they are going to see better value in competitive or even lower cost full frame or even APS-C products.

If people focus on the ease of getting 'keepers' no matter the environment with a bulletproof camera and some of the most amazing lenses out there, then they are going to have less problems with the price.

I used to be dual system for years shooting with the 1D series from Canon and the various E cameras from Olympus. Low light was always advantage Canon. Size and weight of the kit and more accurate colors was advantage Olympus.

I switched to just Olympus when the EM-1 series came out simply because I found that, while the Canon still had an ultimate low light advantage, using the Prime noise reduction feature in the DXO raw processing software, there was just not a meaningful advantage anymore. The more consistent focusing especially with fast primes on the Olympus system, I stopped grabbing the Canon kit.

Ha ha that's hilarious - Dxo Prime + Oly = 1DX for low light

I own Olympus too and there's not a snowball's chance in hell with any NR known to man it gets close to my 1DX above ISO 1600. The M1 II is soundly trounced by the D500 at high ISO and D500 is beaten by 1DX and the like at high ISO. You cannot overcome the simple physics of the smaller sensor. NR helps but it can also be applied to the 1DX etc and I will always have my 2 stop advantage.

So I sue my Olympus for day time or not too dark interiors where small size is advantage. Sensor is only real weakness above ISO 800, the little lenses are mostly gems and m4/3 makes the most sense form a size and weight POV. Just fit them with a SOny EXMOR BSI sensor and get me to ISO 3200 and great DR and I'll have no complaints. I still have my FF for ultimate IQ and bigger prints but Oly will be very nice.

BostonC: DPR uses $200 45mm 1.8 on EM1ii vs. $900 56mm R f.2 on XT2 for the comparison tests. The cheapo lens is ok but far from the best of the system.
Not a fair comp.

The 45 f/1.8 is a little gem, very good even wide open, tack sharp stopped down a little. Sure there might be better, but given they aren't using most expensive L glass on Canon's for example, no reason they should go ultra-premium on Oly.

Sergey Borachev: "Compared to its larger sensor competitors, the E-M1 II shows a noise penalty of about 1EV, which is higher than the 2/3EV you'd expect from sensor size alone." - DPReview

After 3 years, the new E-M1 II has gained only a tiny improvement in IQ, while competitors pull ahead and leave it further behind. Not using the latest sensor technology provides, this E-M1 is disappointing in the one fundamental area that is important to numerous photographers, the quality of the image.

I agree Sergey, m4/3 has made very little progress in last 4 years and why I am going to sell my E-M5 eventually and leave the ecosystem. I love the camera and some of the lenses are fantastic but I think Fuji or Sony will be my next mirroless.

This bit is hilarious "We do have a couple concerns, though. Although the camera will shoot at up to ISO 25600, Auto ISO control maxes out at 6400."

You will not even want to use ISO 3200 on this camera too often. It is simply trounced by D500 at high ISO, more than 1EV, probably 1.33EV worse. It's actually worse than the 7DII too at high ISO probably by 0.5EV. The ISO 25600 setting is marketing gone mad.

thx1138: Just word on the Sigma 10-20 f/3.5 EX, it's not worth it, the Sigma 10-20 f/4-5.6 is a lens for less money.

Optically it's just not as good which is a ridiculous error by Sigma. It's only advantage is the constant f/3.5 aperture. The best lens in this class is the Tokina 12-24 f/4.

Thanks for the review, that's some more dollars I can save. I'm leaning more toward something like the new Samyang 14 f/2.4 Premium and sticking with my Canon 16-35 f/4L IS. Hopefully the new Samyang is as good as the current 14 f/2.8 for astrophotography but considerably improves on distortion, and build.

On article Spoilt for choice: which Sony RX100 is right for you? (304 comments in total)
In reply to:

brownie314: I think the super AF and burst rates are slightly wasted on a camera with very little tele reach. I have noted when I shoot wide to normal I rarely need super AF abilities or high burst rates. When I am shooting a long lens - I almost always need fast AF and high burst rates. But maybe I am weird.

What extreme sports are shot with a 24-70 lens. How close can you get to the action and not interfere with the players. I agree with brownie314. This sort of AF and speed needed to be offered in the RX10 first, hopefully with a 600 f/4 equivalent lens.

EthanP99: 960fps at 1080p for the mk 5....

Did you mention that yet?? Thats a huuuge leap.

Too bad it's not true, not even remotely close to actual spec. Do you think this is a $30K Phantom camera. It's 960p @ 1136 x 384. That's still very impressive, but 960p @ FHD would be insane for a $1000 camera and my god the data rates would be astronomical.

vscd: The BEST way to prevent blown out high lights would be a RAW-based histogram. Better than any fancy algorithms... but not seen on recent cams except of some mediumformat ones >15000$ :(

What's the point of ISOless cameras then. We protect highlights at all costs and by shooting RAW you already get about 1EV extra headroom, and then you boost shadows and midtones. Depending on the camera you can get between 4-6EV to play with. Most of these jpg tweaks are subtle and can't handle the extreme contrast we often get. And no jpg will match a RAW for ultimate quality.

On article Nikon reportedly eliminating 1000 jobs in Japan (535 comments in total)
In reply to:

CheersUK: I have to admit, Im a Nikon man st heart, but some of their decisions baffle me. They release the D500, a fantastic camera and top of its class, then someone decided Key Mission was a good idea...and while they are at it anounce the highly anticipated vapor ware, DL series. Its like there is a Nikon rule that for every genious idea, they have to match it with two or three brain farts.

To be fair, the DL series has been delayed entirely due to the earthquake and will ship early next year. The effects of the earthquake on Sony and Nikon have been understated or ignored by most people.

But Nikon is still their own worst enemy and like Canon are taking a top-down approach, only really concentrating on the high end and FX lenses. They like Canon are seriously neglecting the entry level and you wonder what sort of sales figures they'll draw a line in the sand and say enough is enough. They have to change course, even more so than Canon.

On article Next level: iPhone 7 Plus camera review (185 comments in total)

The iPhones have the most useless flash I've ever used on a phone, both my old LG G2 and my current S7 Edge do a much better job and seem to output about 5x as much light. Even at a distance of < 2m the flash has almost no effect at all in daylight for fill other than the catchlight in the eye and in darker environments still struggles to provide adequate illumination

On article Fast Five: Sony Cyber-shot RX100 V Review (405 comments in total)

I dare to say with a list of cons longer than the pros, most other cameras cough Canon cough would have scored a solid 70-75%.

Look Sony has some great tech and ideas, but they are clearly not cooks, because all their cameras are half-baked. 5 releases and still basic issues that are much more important than cramming in as much tech as possible haven't been addressed. A tech heads dream, a photographers nightmare. By the time we are at RX100X, 75% of the issues will be fixed but we will then be looking at a $2K P&S.

In reply to:

eno2: The image quality is fantastic and ISO 6400 is extremely clean!

So sure if you can shoot two stops lower ISO M1 II is great, too bad they don't make a 300 f/2, or 50-200 f/2.8, or 17 f/0.7 or 12-35 f/1.4.

So back in the real world where you have to shoot your D500 at ISO 6400 and the M1 II at ISO 6400 due get the adequate shutter speeds for the action shot, the D500 wipes the floor, it's not even close.

They may well be on par in read noise and QE, but a little sensor can only do so much and the lenses are mostly same speed or slower than FF equivalents.

Jorginho: I don't think iceland in autumn is a great place to test a cam bar the aurora and for a 21 second exposure btw it looked really good! But then again I don't think Iceland is ever worth a visit. Went to the Isle of Skye one day, which is a bit similar. Should be great. When I entered Elgol I had enough and just turned back to my Highland cabin. Never took even ONE pic.
But that is taste.

If people want to see some better or at least more colourful pics look at Robin Wong, who puts the cam much more through its paces. A very nice review.

Somehow no reviewers ever bothered with HiRes, which I can understand but to me it is important to see how it has advanced.

Robin Wongs review shows it is an excellent excellent cam, but expensive at that for sure.

Indeed Iceland is an amazing place and not just because of the jaw-dropping, surreal scenery, but the locals are wonderfully friendly, crime is very low, and they were about the only ones to learn anything form the GFC

Only someone with a frontal lobotomy would say "I don't think iceland is ever worth a visit". I think you've come up with the stupidest comment in dpreview history.
