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-

http://daylifepics.blogspot.com/

Equipment-

Nikon D300,
Nikon D5100
Nikon D3100
Panasonic LX5
Canon G9

SB-800 Flash
Velbon QHD-41 Monopod

Lenses-

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

Parry Johnson: Hmmm... no D400? Perhaps it's the "unlucky #4" Japanese namesake, but I think this is a case where Nikon wants to sell a bunch of prosumer bodies before coming out with the "real" flagship DX camera. In the meantime, my D300/S just took another $50 to $100 dive in the used market.

From everything Nikon are saying, they are leaving open the possibility of a D400. I suppose their final decision may rest on how well FX sells, but of course some will have a foot in both camps.

I take their assessment of this as middle-class DX as being serious and expect a D400 to come. Only the D4/ D300S are currently really suited for sports... But I suppose a D800S could equally be the fix.

In reply to:

Richard Murdey: "The critical thing here is that despite the fact that the D7100 is Nikon's third DX-format 24MP DSLR, its sensor is new, and unique in Nikon's stable."

Yet you don't explain why this is "critical", indeed any of its benefits, only that the LP filter is omitted. But that's nothing to do with the sensor, any sensor can be used with or without a LP filter.

So are you just spinning back the Nikon press release or is there actually anything new here at the sensor level?

The press release claims it's a new sensor in itself, not just that the AA filter's omitted. Sony just announced a next generation 20mp sensor, so my hope is it's a derivation of that, though it's true, they may just be referring to the removed AA filter. If not, maybe a D400 with D800-class AF, much larger buffer and such a sensor is still to come?

In reply to:

aarif: Is this the same sensor made by Sony used in the A77? I hope not but if true why they didn't use the newer generation 20mp Sensor from Sony unless that is going to be used for the actual D300s replacement maybe

If the new 20mp sensor is in fact 1 stop better, it's a shame they couldn't use it here. But they do claim it's a 'new' sensor, so maybe it's a higher resolution version of the Sony 20mp one, or at least better than the D5200's?

Wow finally a real update to my D300! I have waited a long time or this and the specifications sound excellent. I can only hope it is indeed a new sensor, improving on the (already good?) one in the D5100. Very happy to hear this news. Semi-pro DX is here to stay.

G Davidson: Very technical, but hope they soon allow 30fps. Seeing the difference, motion's a lot smoother and people can always limit it to 24/25fps if they want. Sounds like processing this amount of data is difficult, so it may be a while before they offer a 'true' 8k model. Which makes me wonder- isn't high resolution film still a better archival format? Sorry to be inane, but when something is touted as the best thing since sliced bread, sometimes it's good to point out it's limitations.

Excellent point, in this sense for most people digital is safer, especially if you can do multiple back-ups. I do wonder for feature film makers, though, if formats like this will stand the test of time as well as conventional film, especially the 70mm variety. Digital is often presented as state of the art and as if it is the only available technology. Film at it's best still has a lot of advantages and I'm not sure I like the glossy, plasticy look of digital for conveying atmosphere, though of course it can have filters applied a la Instagram.

It's a little sad for me that despite all the fuss, digital is still a work in progress, without the maturity film has achieved through years of evolution. An 8k scan of an old 70mm film would offer so much more detail and subtlty than this, but given the choice of convenience, who would bother?

Anfy: A pity the camera has not a built-in motor for AF and AF-D lenses, it would have been the perfect choice for me.

I couldn't agree more. What is this obsession Canon and Nikon have with only making large DSLRs fully-featured? It's one reason why mirrorless is growing, people want small, well-featured cameras, not just oversized ones. Well, I know I do!

Direct link | Posted on Feb 10, 2013 at 12:45 UTC

Lighten up people! It's about the response (or lack of response) to a mobile phone taking photos, which can lead to a far more natural result. Posed photos may be technically good, but if they fail to capture the feeling of the moment, what's the point.

It's something like the observer effect in an experiment, when the observer changes what is observed. Mobiles simply have a lighter and less intimidating effect. Couple that with the near-ubiquity of DSLRs these days and you can see why pros are trying something different. And yes, the iPhone is a 'good camera', as I am sure other mobiles these days are. The softwear is a big part of this, no doubt about it, but wasn't how film got developed relevant, too?

In reply to:

SLOtographer: I like the idea of EM5 5-axis IBIS and f1.2 (with the DOF of f2.4 on FF). That means you can slow the shutter, keep ISO down, and still get enough stuff in focus. Lots of creative possibilities!

I'm sorry but you wouldn't have a faster shutter speed, as you'd probaby be using a slower high ISO than you could (cleanly) get on a larger sensor. The advantage is size and especially having a less conspicuous camera. When you are travelling this is a big deal. Who actually travels with 85mm full-frame lenses?

In reply to:

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.

In reply to:

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.

Direct link | Posted on Feb 2, 2013 at 00:08 UTC

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.

Direct link | Posted on Jan 30, 2013 at 14:05 UTC as 10th comment

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 5th 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.

In reply to:

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.
