About me:

Future plan- to make books with my photos fused with poetry. At the moment, they are in online galleries and photo-blogs, like-



Nikon D300,
Nikon D5100
Nikon D3100
Panasonic LX5
Canon G9

SB-800 Flash
Velbon QHD-41 Monopod


Note- I try to stick to 'bright' lenses, so as to control the depth of field and to have a brighter image in the viewfinder, though for traveling and ultra-wide angles I compromise on this.

Nikon 24mm f/2.8D.......................(street photography, walk-around)
Nikon 28mm f/2.8D.......................(events, walk-around)
Nikon 35mm f/1.8 D.....................(my other walk-around)
Nikon 50mm f/1.4D.......................(low light and portraits)
Nikon 17-55mm f/2.8 DX................(events, weddings)
Nikon 18-55mm f/3.5-5.6 VR..........(for traveling light)
Nikon 18-105mm f/3.5-5.6 VR........(travel)
Nikon 35-70mm f/2.8D...................(my DX portrait zoom)
Nikon 70-300mm f/4-5.6 VRII.........(nature, travel, candids)
Nikon 80-200mm f/2.8 ED AF..........(candids, nature)

Tokina 12-24mm f/4 ATX Pro-DX.......(wide landscapes, events)
Sigma 50mm f/1.4 HSM....................(portraits, details, bokeh, low-light)
Tamron 90mm SP AF f/2.8 Di...........(macro with amazing, beautiful bokeh)

I recently sold on my Nikon 24-50mm AF, Nikon 70-300mm ED AF and Tokina 28-70mm AT-X AF SV, as they are not so useful on DX and their ranges are covered better by the lenses above.

Most Wanted Lenses-

70-200mm VR
85mm f/1.4D
17-55mm f/2.8 AF-S DX Nikon/ another equivalent zoom for DX, like the Tamron 17-50mm version

tkbslc: 85mm equivalent f1.2. Not too shabby at all. (I'm not sure why people are having a hard time with the 42.5x2 math.)

150mm f2.8 could be a killer sports lens if the focus can keep up. Not sure who else really needs a lens that long and fast (and probably expensive).

The reason that people are only really interested in the depth of field equivalence, is this is why you'd want a fast portrait lens in the first place. In terms of getting more light, this is balanced out through the noise level and ISO performance being better with a larger sensor (of the same generation). I'm not even sure this would get more light, as the smaller opening might actually let in less at a time.

So it's advantage is mostly within the m4/3 framework, where it may be one of the best for portraits with autofocus. Also, m4/3 lenses are generally fine to use wide-open, whilst full-frame ones benefit from closing down a stop or two, so you get some advantage there.

All that said, I think if people are going to say the equivalent angle of view, they may as well convert the DOF as well, as that way people better know what they are buying.

MikeFairbanks: I've been involved in photography now since 2007, all digital. I take better pictures than someone new at it, but am a long way from being consistent in a variety of lighting situations. I am an intermediate.

As an amateur who shoots almost daily, I quit using point and shoots and video cameras. Done. I use my Iphone 4s for snapshots/video, and for quality I use a Nikon D7000. (I had some Rebels, which are just as good, but I happened to get a great deal on a Nikon).

My opinion is that manufacturers should focus on two things:

* Shift from APS-C to FF models at various price points/features.
* Smart phone cameras.

Everything else, to me, is a no-go. I won't buy them. I tried them (4/3, etc. Mirrorless), but it's too much of a compromise. I want a quality DSLR and a quality smart phone. I won't walk around with a P&S in one pocket and a phone in the other. The P&S days are numbered, and a mirrorless with a large sensor can't fit in pockets.

FF DSLR + Phone = Future

I think that's going to far, as the majority of uses will be better served with an advanced Bridge camera or CSC. The reason there is no future need for APS-C DSLRs is simple- a sensor like the D800's lets you have all the resolution you want need with crop lenses. Future iterations at 50MP+ will offer even more. Then only the body size is the issue, so you could shrink it and offer grips for larger lenses, like the EM-5.

An excellent article and I think it's telling that such engaging writing and futurism is more to be found In the realm of mobile photography than in it's more traditional cousin.

I too am an Apple fan so share the same longing for their wondeful interfaces in a camera. The smart camera is coming, it can't be stopped and I do hope it does away with the clunky interfaces we are faced with now.

Just a usable, controllable HDR mode would be enough for me, though. The iPhone apps do this better than any camera I've used so I expect given the processing power and softwear, large sensor cameras could be even better.

If this can do better than the not-so-well reviewed Olympus one, whilst being a lot lighter than the Panasonic offering, it could be a very nice choice for a travel ser-up.

Looking more at the P520 on Nikon's site, this seems to be a surprisingly minimal update. Same shooting speed, EVF, lens, only questions remain about whether the sensor, AF and VR are really better, as the P510 has a lot of trouble autofocusing at longer lengths and is very smudged above base ISO. The battery life was already pretty bad and now worse, but at least they include a charger now!

Yet, leaving aside the lack of raw or a hotshoe, which I really find hard to fathom, if it really is a better photo-taking machine, the update will be worthy.

Direct link | Posted on Jan 29, 2013 at 14:36 UTC as 6th comment

So what's really new for the P5200? Higher resolution sensor, but does it have better high (or even medium) ISO? Better VR? I was hoping especially for better AF and a Raw mode, but no word about those. As for the lens, it's long enough for me, but maybe a hard sell when the competition is offering 1200mm.

I think a lot of people are underestimating the importance of this kind of camera. Its true that right now, 'one size doesn't fit all', but in the future the versatility of something like this could well make most other cameras either specialist items, or obsolete. The variety of images possible and their already reasonable quality should really make manufacturers take note. A 'killer' bridge cam could well take off like no other camera before it.

Steen Bay: Overall a fine/fair review, but can't agree that a tripod almost is a necessity when shooting at full zoom. The IS is so effective that you most often will get sharp images (of at steady subject) at 1/125 sec or so at 1200mm (equivalent), or even at even slower shutterspeeds with a bit of luck. So in good light it's perfectly possible to shoot handheld at base ISO at full zoom.

The great depth of field produced by a small sensor makes for less obvious camera shake, or mis-focus. I don't think you could do this on a DSLR.

Aleo Veuliah: These two cameras, Panasonic Lumix DMC-FZ200 and Canon PowerShot SX50 HS, are the best bridge cameras on the market.

I'm wondering that. Wouldn't this be the most apt comparison, as they both have such a long zoom range? Presumably, the Panasonic can only have such a bright lens because it's around have the length. Also, the P510 got a silver award but this didn't, is this just because of a changed environment, or is it still considered the better camera here?

zinedi: Ridiculous zoom with ridiculous speed 3.4 - 6.5,
ridiculous EVF - 202.000 coloured fuzzy spots,
ridiculous tiny sensor crammed with 12 million hopelessly squeezed pixels trying to catch a one foton,
ridiculous massive force of software necessary to fabricate from this hardware mess some digestible image,
ridiculous plastic fuzzy pictures good to watch on the mobile phone display.

Victory of Vanity Fair over good reason, victory of marketing races over science and technology.

I'm surprised at the vitrol over the attention this camera is getting, but think for a moment. Is there any ither realistic way to get such a large zoom range than use a small sensor? I just got a Nikon P510 for birding and am finding the range fascinating for other uses too, though I'll admit, it, like this is a 'good light' camera and not an 'low light' camera.

I dismissed these bridge cameras too, but in use they are a liberating experience.

maniax: Waste of money this digital moviemaking. In 10 years there will be probably some 20mpixel video mode and your 2k/4k old stuff will look crap. While something shot on 35mm film or higher could still have more details.

4k isn't all that much resolution for a lens... I expect they'll work fine on 8k cameras as well, after all they work on 20mp+ DSLRs.

In terms of the video I agree though and thanks for your insight, 4k digital won't stand the test of time as well as modern film will, yet I expect it's a lot easier to deal with.

Mssimo: Does autofocus work with the adaptors?

That's what would make or break it for me. I suspect it doesn't, as the AF is proprietary.

IrishhAndy: Thought I'd get in before the crowds. Looks like a nice cam but over prived and a kick in the teeth for XE 1 owners.

I'm afraid that's just the way it is with technology these days. Despite the high prices and rangefinder looks these are internally computers, with incremental upgrades planned in advance. Either be prepared to pay a lot more, or keep enjoying what you have until the next set of 'irresistible' upgrades, as its never going to end.

In this case of course it's an upgrade to a different line, it will be a while before this makes it to their more versatile interchangeable models. It is a scary thing to invest in a camera, especially lower-end ones that chane more often, but that's the whole technology thing.

mosswings: We're moving closer to the modular, wearable camera at blinding speed, driven by the rapid collapse of the casual camera market. Imagine bluetooth-pairing this "capture" module with a wearable viewfinder like Google's Glass or Vuzix's Smart Glasses:
And you get where both the consumer communication and imaging market may be headed. Enthusiast formats could benefit from this as well - the eyeglass portion of the image capture system could incorporate extremely high resolution monitors. You could still use big ol' lenses if you wanted, except now you'd snap on a tiny capture module and you'd hold them like a camcorder or a beer can on its side.
Although this isn't a replacement for enthusiast cameras, it is a hopeful sign that at least some legacy manufacturers are thinking out of the box.

I've recently had people visit me here in Japan, where they've also done a fair bit of traveling. Whereas years ago they used to bring simple compacts, now it's all iPhones and their photos are probably better. Certainly it's less to carry. So yes, from what I see, casual photography is moving to smart phones, in a way it never could to the dumb ones.

Then, when friends want something better, they aren't so often going for a better compact. More are getting entry-level DSLRs or mirrorless. Deservedly or not, the reputation of compacts is 'not good enough' and in terms of end results, not much better than their phones.

A very interesting camera. I too remember the heady days of early digital cameras, where the movable nature of the LCD lead to many unorthodox, but possibly very usable designs. This seems a return to that, though I admit that a cell-phone camera with all it's apps is hard to compete with for instant uploading.

I could see this being a fun and creative 'take-anywhere' camera, with pleasingly unpredictable results. Even with all the 'fun' filters on cameras these days, it's not so much fun to use them if you know what you'll be getting. You don't always need all the sharp detail a digital camera is capable of... But it's nice to see it will save an unfiltered photo alongside it.

My only concern is that the filters I've seen on cameras are way cruder than those in the best apps, like Instagram, or Hipstamatic, where they have so much character. I hope they can be as striking and on this camera.

G Davidson: I wish they'd just make an interchangable lens option, who wants to buy the set just to have the variety of lengths?

I have what is probably the same 19mm lens from the DP1 in m4/3 mount and it works fine, though it's a bit bulky. Probably this is mostly marketing-speak, though they may adapt the lens housing specially for each model.

Maybe they are waiting for the technology to develop (high ISO, HD video) before they commit to a Fuji Pro-1 style interchangable version. Denying one is in the works would help sales of this, but I can't imagine they'll hold off forever. Many would buy all three lenses, the trick is to have a marketable system in an already crowded space.

This looks like a good all-around camera for someone who doesn't want to get into DSLR's, though it still rests on it's IQ. If there is any benefit from the new sensor, that long zoom range might be interesting to use, though images usually get so soft it's like using a teleconverter. When someone gets one of these right, it would be great for birding.

chadley_chad: So every decent spec camera that's not DSLR shaped gets called a NEX wannabe ... Interesting!

So yet another new camera gets blasted for not having a built in EVF ... Stupid!
If you want an EVF buy a NEX 6 or 7 ... Not everyone wants or needs an EVF and those that do, look elsewhere ... Simple!

NX & NEX kind of similar name isn't it?. They really should have got together the way Olympus and Panasonic did. Despite being fierce competitors, maybe they will, with AF-ing adapters?

Fantastic survey of what is one of the most democratic (and exciting) area of photography right now. There is no doubt that as sensors improve, smaller ones suffice. Also, regarding Hipstamatic, whilst I often wish they'd let me simultaneously save a 'normal', unfiltered photo, there's also no denying that making it a one-off capture is a very powerful approach and one that get's me using my iPhone camera more. I'd venture to say that their photos get almost no post-processing other than the app's processes- a rare thing in the often convoluted 'workflow' of digital photography.

Also, regarding Instagram, I think they really were planning to use user's photos in advertising, though maybe not sell them per say. Luckily they backed down and people like me were able to keep their account going. Also, like a lot of people I use it more to share DSLR/compact photos rather than mobile ones. For me mobile photography is more about the sharing than the taking.
