A couple of months ago Nikon announced the latest in their range of Digital SLR cameras, the D3 and D300. These are targeted at the top of the range with a price tag of £3400 for the D3 (yes that is three thousand) and a slightly more affordable £1300 for the D300.
Today and tomorrow Nikon are putting on the Nikon Solutions roadshow where they are proudly displaying not just the D3 and D300 but also the full range of Nikkor lenses and lots of other accessories as well. Apart from the shiny, expensive hardware they are also running a series of seminars helping photographers get more from their imaging workflows. The most interesting feature here was the total lack of wet film... Everything was digital.
Normally we would not bother to report on something like this, but there is a GPS link here (pun intended...). Both cameras have a special 10 pin connector which amongst other functions allows you to connect a GPS to the camera. This then provides a NMEA datastream from which the camera can extract the positional information and stamp the image meta data with the location that the picture was taken.

If all that sounds a bit daunting don't worry I will explain it a briefly below.
When you take a picture with a camera a number of attributes are stored with the picture. You can view this as 2 files of data one of which is the image itself and the other is a series of attributes which describe a number of things about the image. You will be used to seeing some of these such as the file name and the file date, some of you may also be aware of the File Created date. There is a defined specification for these attributes known as EXIF.
These additional attributes describe all sorts of technical information such as the camera make and model, the exposure settings etc. Amongst these data is a definition for GPS Latitude and Longitude. Of course there are very few cameras that can automatically insert this information into the metadata, but they are becoming more prevalent. In particular the new Nokia phones with embedded GPS place the position into the files, and of course the Nikon D3 and D300 have the capability with added hardware to do so as well.
This year I have reviewed a number of GPS systems that offer a mechanism to match GPS tracks to digital photos. Whilst these do work they add an additional step into the workflow and the possibility of errors creep in with each additional step. The beauty of having the camera stamp the image when the shutter is pressed.
OK so now we know what it is, but what use is putting this data in the file? Well I know a lot of photographers who always like to know the exposure settings of each picture, this system just takes it one step further and lets you know exactly where you took the picture. But the position is meaningless unless you can do something with it... Fortunately the likes of Google, Locr, Flikr and many others allow you to create Geo-referenced image libraries. This allows you to display your pictures in Google Earth or on Google Maps. This really takes the photo album to the next level!!!
Diversion over how does this work with the Nikon D3 and D300 cameras? Well apart from hundreds of levers, switches, and buttons they also have a propriety 10 pin connector positioned right next to the lens. This connector allows you to plug in a number of external add on devices to the camera.
One of these is specified to be a "GPS Cable MC-35". This allows any GPS unit outputting NMEA 0183 compliant data to be connected. The drawback here is that the interface cable is $99 or £50 and presents a standard serial interface, most modern GPS systems are using USB nowadays...
All is not lost though as I was talking to Jimmy Huang of Evermore Technology recently and they are testing an Evermore GPS receiver with a Nikon interface cable. No prices were discussed, but I wouldn't mind betting that it will be very competitive.
Another option available is the GeoPic II from customidea.com this is a device designed specially for the Nikon D3, D300 and other pro cameras. This cunning little GPS receiver is located in the flash shoe with just a short cable to the connector on the D300.
The GeoPic II is designed specially for tagging with digital cameras as can be seen from the design locating in the flash and the neat cabling. But it is not just the hardware that is set up specifically for digital imaging the functionality is too. The GeoPic II has three operational modes: Low Power, the GPS is only active when you are about to take a picture; Continuous, the GPS is on all the time; and Freeze, the GPS is off but the last position is reported. This last mode allows you to take pictures indoors or in areas where there is no GPS signal and still tag your images.
This solution comes at a cost though. The GeoPic II uses power from the camera and thus will shorten the operation of the camera. The GeoPic II is available for £200.
Apart from the GPS side of things the D3 and D300 are stunning cameras, with lots of new and improved features. My favorite was the Live View on the high density 3 inch LCD display. It also has video output to a HD TV using a HDMI connector. Helping you make use of the 12.3 megapixel CMOS sensor. I also tried out the 18-200 VR lens and the 105 VR Macro lens on my D70 and these functioned really well, both in terms of focusing speed, operation at slow shutter speeds and sharpness.
My Christmas list is in preparation... Nikon D300 with 18-200 lens and 105 macro to back it up. What's that I heard my wife say? Something about Hell and freezing... :( Maybe I can persuade Nikon to let me test one.
In the mean time if you can get to Olympia in London tomorrow (November 28th) you can see the new Nikon cameras for yourself.

Sony Cyber-shot DSC-T200 compact camera
By Rob Thomas
The first thing you see when you pull the T200 out of the box is a great big sticker proclaiming the camera delivers “Full HD 1080” still images. So you would've thought that Sony would make it easy to enjoy this feature. But no - it’s only when you read the instruction book that you discover that the HD connecting cable is an optional extra. Duh.
That’s not to say that the T200 doesn’t have some very nice features. For a start, it looks very smart and if you’ve seen the DSC-T100, you'll have a distinct feeling of déjà vu as they look almost identical. Both cameras use a sliding front cover which protects the lens and powers on the camera when it’s pushed downwards.
Sony's DSC-T200: smart-looking snapper
Along the top of the T200 you'll find the power button, shutter button, a tiny playback key and a zoom lever. At the back, you'll find the 3.5in LCD touchscreen. Actually, it's closer to 3in in reality, because the display has black borders on both sides. Finally, at the bottom is situated a slot for the lithium-ion battery and another for the Memory Stick Duo/Pro card.
Inside, there’s 5x optical zoom, Carl Zeiss Vario-Tessar lens equivalent to 35-175mm on a 35mm camera, plus the usual Sony offerings: Steady Shot, red-eye reduction and face-detection systems. Image size ranges from 3264 x 2448 down to 640 x 480 pixels, and there’s 31MB of internal memory. The ISO range is from 80 to 3200.
In addition to the 16:9 mode, the DSC-T200 also shoots in 3:2 aspect ratio for postcard-sized prints and can shoot movies at 640 x 480 resolution at 15- or 30fps. There are ten scene selections, including landscape, beach, snow and smile. But more on this later - for now, it's enough to say that if you like lots of manual control, then this is not the camera for you, although you can tinker about with the focus, exposure, white balance, flash and metering, depending on what camera mode you’re in.

If we had to sum up in one word how the DSC-T200 operates it would have to be 'fiddly'. This isn't the most intuitive camera to use, which might come as a surprise as it boasts touchscreen control. Now, touch control can be good, especially if you’re using a microwave to heat up your pizza, but we’re not convinced that it works that well on this camera. For a start, the screen isn't that sensitive and we found that you had to press it fairly hard to get things moving along.
Using the touch menu system involved a lot of tapping, and Sony seems to have thrown everything but the kitchen sink at the menu display. In normal display mode, there are more on-screen icons than on a Space Shuttle flight deck and even the simple display format is festooned with icons for image size, timer, recording mode, menu selection, flash mode, macro and display type. There’s also a Home option that lets you select auto adjustment, screen selection, program auto and movie modes.
Setting up the DSC-T200 involves wading through various pages and sub-menus. The power and playback buttons are small and fiddly, and the zoom lever can be frustrating to use as it’s not easy to make fine adjustments with it. Even the cover for the battery and memory card slots proved to be a pig to open and close.
Although it is a case of the 'nice performance, shame it’s a bugger to use', don’t run away with the idea that we didn’t like this camera. Switch on is easy, although it seems ages before the DSC-T200 warms up and you’re left a staring at the white legend “Sony Cyber-shot” on the LCD screen for several seconds before the camera springs into life. But once ready, the DSC-T200 is a pretty fast worker and shutter lag is hardly noticeable.
Picture quality was very good under a wide variety of shooting conditions, including low light. Even with the ISO set at 1600, the DSC-T200 produced sharp images with little noise – we were impressed. The movie mode cut the mustard too, with smooth action and reasonable sound quality.
Two features we really liked might seem a little trivial, but they are fun to use and shouldn’t that be part of photography? The playback mode includes a slideshow, which has the cheesiest music soundtrack we’ve ever heard – it’s so bad, it’s good!
In addition to the face-detection system - which works well - there’s a smile shutter mode which is designed to only capture – you guessed it – smiles. We tried this out and to our surprise it actually worked well. Scowl at the DSC-T200 in smile mode and it refuses to take a shot. Simply open your mouth wide and it doesn’t want to know. Even a half-smile isn’t enough to excite the camera, but when you give it a full smile, it fires off a shot. So hats off to Sony for producing a camera that performs well, even if it isn’t the most friendliest to use.
Verdict
A bit of curate's egg of a camera. It offers a very good performance and quite a few useful features, including some that are fun to use. But it's let down by a rather temperamental touch screen interface and some fiddly controls.
A camera that delivers good pictures but is let down by a iffy touchscreen system and Multiple Menu Madness Syndrome™...
