Yikes! So I look at the gallery and the images seems pretty good and I think mot bad. But then I click to download the full sized images and OMG, they are very poor. Mushy as all hell and these are supposedly processed from RAW and as good as it gets. Whatever you do, don't look at 100% and don't print bigger than about 8x10. Another camera ruined by those pitiful 1/2.3" sensors that are like a vile plague.

ThatCamFan: Seeing the noise performance, all I can say is OUCH, Canon is still so far behind.

This camera's high ISO may suck and it does, but it's hardly as though their other cameras are the same. Their FF cameras have superb high ISO. Use a 1D X or 6D.

Mal69: I just use a multi coated B+W polarizing filter, when turned the right way it eliminates those reflections, alternatively if the picture is very important i use my superpowers to levitate outside the window while i take the shot.

I think this will be good for all those camera phones of which there are tens of millions around the world.

Do you have one for your ultra-wide angle lens with bulbous front element.

The original application was in machine vision. I was working on something similar in eliminating specular reflections to be able to 3D image metals and came across this work 2 years ago. It may of been useful if our project was not canned.

Zero people shots is fine by me, landscape and nature pls.

RichRMA: Imagine that. Actually upgrading a camera's focusing system without requiring the user to buy a new body. Would that other companies followed this.

Or you could look at it like: Fuji had good hardware but poor software and have needed a lot of firmware updates to finally unlock potential. While it's nice to see them continuing to work on the AF, I'd rather they got it much better to start with and didn't rely on firmware for major upgrades

Rex1227: Does that mean the a shot at a specific ISO cannot get any cleaner up to a point since the amount of photon noise cannot be reduced?

Yes if you had ideal electronics and there were no other sources of noise, the shot noise would be the noise floor.

muvovum: and once again Oly gets the medal for being the first to introduce the hires mode, when they weren't the first ones. AFAIK it was Hasselblad.

LOL I think Phase One or another MF maker with their true 80MP sensor were the first with hi-res mode.

We don't need no stinkin pixel shifting gringo.

Why do so many people feel slighted if dpreview doesn't come up with an answer they like. Do you need to vindication you made the right decision? Best reviews about actual performance come from users themselves. Formal reviews are good for some things like features and ergonomics etc, but things like AF prowess and tracking you need real world experience from people that know what they are doing.

Peiasdf: "nine elements arranged in six groups". Isn't this kinda too simple for a super fast prime?

After 50mm, 85mm is simplest to design and both are quite similar in design.

Stephen Scharf: This is another example of why the majority of users in most use cases don't need or, more importantly, cannot fully utilize ≥ 24 megapixel resolution either in APS-C or "full-frame" sensors; this level of resolution requires a lot of mechanical engineering workarounds just to obtain a sharp image, as well as impeccable shot discipline. I'm not saying shot discipline isn't important, it is, but it is often not achievable in a wide variety of use scenarios.

As I stated here before, this constant "push" by the media for more and more resolution isn't really best serving customer needs, it only drives incrementalism rather than real innovation. The latest 50 megapixel Canon 5D models are another example of incrementalism rather than true innovation. Most importantly, if you've read Thom Hogan's recent survey results from a statistically significant N of responders around features that they really want, the majority of customers are *not* asking more resolution.

Why do you think Canon or anyone has to make cameras to suit everyone's taste. If you don't want a 50MP camera don't buy one. You have a ton of choice. I know a lot of landscape and fashion guys from Canon that have been demanding this for a long time. Canon admits it's a niche camera so what's your problem?

mpgxsvcd: First off Great interview. Secondly, great responses. I was not a huge Nikon fan but I respected their products. However, after this interview I can truly see how dedicated they are to their customers.

This is in stark contrast to the last Canon interview where they basically said F.U. we are better than everyone else and if you don't like it then we don't care.

I have said it before and I will say it again. Canon is doomed simply because of their attitude towards their customers. I know their downfall won't happen anytime soon but it will happen one day unless they adopt a great attitude like Nikon demonstrated in this interview.

I really hope that they keep developing the 1 series. I really liked their most recent iteration of that camera. Give it a few more iterations and I think they might actually be able to gain some traction in the mirrorless world.

You are kidding, one of the least informative interviews I've wasted time on reading. Borderline farce.

Direct link | Posted on Apr 11, 2015 at 02:56 UTC

What a lame interview from Nikon. They might have as well pleaded the fifth and refused to answer any questions. Learned nothing at all from them, other than they should become politicians. Compare the lack of detail coming from Canikon compared to others and they still have this air of superiority. We're too important to give you details, just wait and see what we release and be impressed.

On Sony Alpha a7 II Review preview (809 comments in total)

"Our lab tests confirm that the Sony a7 II does between 1 and 2-stops poorer than the Nikon D750"

Totally ridiculous Nikon can blow Sony away for noise from basically an identical sensor, and has always been the case. Given the much increased weight of the A7 II, the p!ss poor controls, average AF, the D750 is hands down a much better camera other than lacking IBIS, but Nikon has so many VR lenses who cares unless you have a lot of legacy glass. Only thing about the Sony that's much better, the amazingly versatile mount allowing almost any glass to mounted. Nikons mount is way past it's useless use by date.

On Olympus OM-D E-M5 II Review preview (797 comments in total)
In reply to:

BennoFG: How can this not be a stand out camera?!
This is absolutely a stand out camera.

It does 2 things better than any other camera on earth can do.

push a 64mp raw file out of a 16mp sensor from precise half pixel-shift increments. (don't talk about restrictions, it is what it is and no other camera can do it better.)

Offer 5 stops of image stabilisation for any (ANY) lens that is attached to it.

I don't feel Olympus and the EM5II are getting as much recognition as they deserve.

How does it stand out? I have the E-M5 and don't think it stands out. Sure this is overall better in most areas, but I see nothing ground breaking.

On Olympus OM-D E-M5 II Review preview (797 comments in total)
In reply to:

thx1138: Why not down sample the 64MP RAWs to 40MP rather than post them at 64MP?

While I can many improvements over the original E-M5, IQ has barely budged and this is my main bugbear with the m4/3 sensors, they seem stuck in a time warp. While I love my E-M5 going forward I'm not sure I'll stay in that ecosystem unless there is a genuine breakthrough on the sensor front soon. But I do love the lenses so hard to give those up.

Also disappointing to see the woeful menu system still in place by Olympus and I guess the manual is still as bad as ever.

Clear lack of reading and comprehension skills shown by many on this forum. Where did I say anything about resolution, there's a lot more to a sensor than pixel count. 16MP if fine for such a small sensor, but there has been no progress in DR, low ISO shadow noise, high ISO noise since the E-M5 came out.

Sad to see how insecure many mirrorless fanbois are about their toys as any criticism is not tolerated. Actually it's quite pathetic.

nkistrup: 0-stop circular polarizer? That alone is intriguing.

My lenses are geared for macro & landscape work, but it seems that attribute would be nice for the 150-600 long telephoto lenses.

They are not implying that at all.

luxor2: Transmittance values are improbable!

Clearly they just mean the glass not including the polarization foils. You want the highest transmittance glass as your starting point.

Nice enough video but we have zero proof of the tracking ability. What is the keeper rate, where are the 100% crops of the full size RAWs? Show me those and I would be far more impressed if it really can deliver consistently. Anybody can get a a sharp shot now and then, but what about 95% keeper rate and by that I mean critically sharp at 100% view.

However, the lack of EVF and the small size are a total turn off for me especially when hanging large glass off the camera. Heck we might as just well integrate the sensor into the lens, the body is so small as to be useless. Menu driven control is a total joke for a serious action camera and is bad enough for general walk about shooting.
