On article Olympus m.Zuiko 17mm F1.8 first impressions and samples (255 comments in total)

In good daylight, will this be substantially better in IQ than the 14-42mm m34 kit zoom at 17mm as a general walkabout lens?

emircruz: Here's a quick pivot of the Results:

By Brand Top 3
1. Nikon 4429 Votes - 29.91%
2. Olympus 3576 Votes - 24.15%
3. Canon 239 Votes - 16.20%

By Sensor Size Top 3
1. Full Frame 8010 Votes - 54.10%
2. Micro Four-Thirds 3864 Votes 26.10%
3. APS-C 1837 Votes 12.41%

By Type Top 3
1. DSLR 7313 Votes - 49.39%
2. Mirrorless 4778 Votes - 32.27%
3. Fixed Lens 789 Votes - 13.01%

Seems to point to a future where we have
1. Relatively affordable, very high IQ FF cameras. Possibly mirrorless and hybrid AF systems that combine the best of PDAF and CDAF.
2. Micro four Thirds becoming the default quality compact camera, and also the prosumer choice with interchangeable lenses
3. Casual cameras all stick to phones, tablets, and whatever else new gadget will have decent casual cameras on them.

Interestingly, the maker pushing for FF is Sony. Despite the strong show by Nex APSC cameras, Sony does not have an entrenched market position in APSC DSLR market that still belongs to Canon and Nikon. Sony have figured out, correctly IMHO, that they can make the canikon buyers switch by offering them FF, high IQ, in quality cameras. Probably two different series/models - one at the high-end pro users and the other aimed at prosumer apsc DSLRs.

Sandwiched between M43 and FF, will APSC DSLR be the next category to die after the brutal boodbath in compact P&S cameras?

Artistico: Now, to get the best possible photos from this, one can just take three photos, one each with a green, red and blue filter and combine into a colour photo which can then be turned into a black and white photo again with a proper channel mix. A bit of a hassle, I know, but it would make for killer landscape photos.

If I'd have been a recent lottery winner, perhaps I would have bought one of these - just for fun. The sample photos remind me of some of mine from the days when I used to own a Leica M6 with the old 50mm Summicron: A bit bland, but with plenty of potential.

I'd underexpose and push in post for a slightly more contrasty look without burnt-out highlights.

Just taking your idea further, could Lieca or Panasonic make a colour version of this by using 3 high-grade colour filters that cover the sensor for 1/3rd the exposure?

Sounds cumbersome, but we've had glass (mirrors) moving in and out of position in front of the sensor for ages now. So, the mechanics cannot be too hard.

Could use the colour filters on a wheel/ angular motion, with each of the three raw images saved. Plus, a jpeg of the three raw images combined in camera.

Full detail colour landscapes and still life! and a choice of going monochrome when you want to.

Fearless_Photog: This same pixel binning was used on the Nikon D1H, it was a 10 megapixel sensor, but with 2.7 megapixel output, because they didn't feel like the quality of single pixels was high enough at the time.

The D1H was $4,500 body only. And 1.1 kg before you put a battery in and a lens on it. Amazing how far tech has come in these 10 years. Nokia 808 = 41Mpix binned into 5Mpix output, plus lens plus battery all inclusive for $450.

And of course, it has a music player and a phone and a GPS navigator thrown in for free :)

The 4:1 binning on Sony's 10Mpix sensor in the D1 had another purpose in addition to reducing noise. The pixel density was state-of-the-art at that time and sensor yields were low. Binning 4 pixels into one output pixel helped increased yields enough to make the sensor/camera feasible at $4,500!

Photato: 38MP pixel sharp handheld?, yeah right LOL
Would rather have 5 Big Fat MP like the pro cameras.

This Nokia sensor's normal output is a "5 Big Fat MP" picture, just as you asked for. Low noise, high quality output. How does 5MP on a sensor almost as large as Nikon 1 sound?
Seems to beat most P&S cameras hands down.

Picture quality will certainly drop in the full-res 38MP mode. Probably best used with some sort of support/mobile tripod in good light. Nokia could do some sort of a combo holder that works as a car mount (the phone has GPS + locally stored maps + voice navigation) as well as a mini-tripod.

Unless, with all the fancy pixel-binning processing in-phone and the sheer number of 'spare' pixels, Nokia has implemented digital IS. I don't know, but it's a real possibility for this approach to imaging.

Of course, I haven't held this phone camera in my hand yet. But, at that big sensor size, I'm willing to believe. And, given Nokia's track record with the N8, they do have credibility in producing the best pictures out of a mobile phone.

The spiritual successor to Nokia N8, and the P&S killer.

Apart from astonishingly high quality still pictures, Nokia is claiming Continuous Focus 1080p full HD video. There's a separate xenon flash for pictures and an LED video light for shooting video. And it has Dolby headphone tech for playing music/ surround sound from movies.

With IQ reaching levels entry-level P&S cams cannot provide, will it be end of the dedicated P&S camera? Lower-end m43 (like EPL1) and large-sensor enthusiast bridge cameras will probably become the entry level for camera companies.

As the DPR sensor size comparison shows, the Nokia sensor is pretty close in size to Nokia 1 and far bigger than compact cameras. Negative /marketing/ impact on the Nikon 1 system?

Nokia has indicated a price of $450 without carrier subsidies. That should fall to $100-150 range with standard 2yr contracts. And once Nokia has the tech in Windows phone, I guess the Symbian/belle models will drop further in price.

Suggest you crop the picture to either remove the half-person on the left edge of this picture. Or include the person fully, providing a focal point for the dancer's movement.

On article Just Posted: Nikon 1 V1 and J1 review (424 comments in total)
In reply to:

marike6: I actually think DPR got this one wrong. They kind of reviewed these cameras as Advanced P&S's, and even state in Good For sections, for "soccer moms". But then they clearly subtract quite a lot for lack of external, hard buttons as if the reviewers tried to use these cameras as DSLRs.

The Nikon 1 has a fairly brilliant sensor, with excellent color depth, and very good high ISO performance. That it doesn't equal the 16mp m43 sensors of the G3 and GX1 shouldn't even be mentioned as a minus. It took Panasonic 4 iterations to produce such a sensor. Why should the smaller, first generation Nikon 1 sensor be held to this standard? Brilliant video mode, great IQ and performance. The faster glass, and prime lenses be announced soon.

Next month we'll see DPR fall all over the new Canon G1X because it has a large sensor. I predict it will get a Gold Award. The slow focus, slow f2.8-5.8 fixed zoom lens won't matter or adversely effect the score at all.

It may have taken Panasonic multiple iterations to get to the current 16mp sensor. But that _current_ 16 MP panny sensor is exactly what Nikon has to compete with _today_.

So, why would a buyer pay more for Nikon when he can get a better camera for lesser? Would you like to subsidise Nikon's slow response to mirrorless cameras and pay for Nion's arronagnce in pricing it higher than its more capable competition?

And, hope that they eventually improve in a couple of year's time. Of course, Sony, Panasonic and Oly will be sitting idle this whole time, right?

In reply to:

photo nuts: I like this statement:

"... this is due to the relative accuracy of contrast-detection AF systems compared to phase-detection: 'it's really difficult to achieve accurate AF [with a phase-detection system] and the more pixels the camera has the more difficult this becomes'."

Well said. :)

Which is exactly why we need a CDAF driven by a phase detection based prediction. The zone of uncertainty where CDAF has to confirm focus becomes so small it'll not be slower than purePDAF once some design improvements are added.

For Foveon sensors, there may be a unique possibility - it already has 3 laters of photosites sitting at each pixel. Could one layer be used for phase detection while another is used for contrast detection - at the same time?

A bit muted... looked even a bit faded to me at first glance. A bit more 'pop' would have made this picture very celebratary indeed!

Andre, Barb,

Said this to Patty, but thought this is a better place to convey it to you directly.

The collaboration on this challenge - wow!

Hats off to you for thinking up this format. You may have hit upon the ultimate 'social' form of learning online. For me, a longtime lurker/reader of DPR, it's made finally joining the site very worthwhile.

Many thanks.

GuptaD42: The lightening up of the girl's face has focused attention on her expression. I feel her expression doesn't really match the air of sophistication and mystery in this shot. As if she's trying too hard and is not one with the flow that this picture seems to be all about.

I was expecting much from your second version, as I had found the first one to be among the best compositions here. The flowing shapes are indeed clearer now.

Since you mentioned that this was shot as a series, do you have anything else from the same series that might work better?

I've had the good fortune of working with a boss who taught his team "power of the huddle" and created an open environment for everybody to share ideas. It often generated solutions the best of us could not have come up with alone.

Like what Matt talks about in this TED chat:

I was impressed with your first shot, and clicked through to your profile to see you gallery. Your pictures speak for themselves. So, it is a happy surprise for me that a pro like you could have something to learn from rank amateurs like me. I look forward to seeing more of your pics and to learn from your inputs, and the larger group's.

The collaboration on this challenge - wow!

This is so much better, minus the harsh lighting. And the reduced clutter. The crop works far better. I think you've given the princess her due. Very nice.

I believe this is it. I think the soft focus goes well with the subject and she's looking in very keenly. Taking out the distrations like the phone, and revising the composition by cropping differently has made this great. Congratulations!
