Geo-tagging - another reason to upgrade your camera.

In November I replaced my Sony DSC-P10 digital camera with a very nice Canon IXUS 850IS. This was quite a big step for me - to move away from Sony, I debated whether I should get a newer Sony and took quite a bit of convincing against it - but at the end of the day, I was replacing my Sony because it had failed, not because it was out-dated. The Canon had excellent reviews, was comparable in every way and I have not looked back since.

The research to find the right camera meant considering the specs and reviews - now I get the sneaking sensation that this spec search in future will need to take into consideration geo-tagging.

Geo-tagging, in the case of photography, is the process of including geographical meta data, usually latitude and longitude to your photographs to tie them to their position on earth.

JOBO have a device, photoGPS, which allows for geo-tagging to be fitted to your camera's hot shoe -like a regular flash unit. This unit captures the country, region and district, city, street, postal code, and even the point of interest (POI) which is closest to the captured image location and adds it to your photograph's meta-data.

This information can be used in a variety of ways. Google Earth allows users, through Picasa to match their photos to a specific location - this opens up all sorts of possibilities for travel writers, holiday makers etc. Or perhaps from a personal history point of view, a record through your photographs of where on earth you have stood - something your children and grandchildren might re-visit or yourself in later years.

Also geo-tagging would offer you a new search criteria, appended automatically to your photos - for those less keen on manual organisation. If you want to see all the photos you took at a specific place then you can.

So with this solution appearing as an add-on for hot shoe enabled cameras how long before it becomes a standard inside your camera? I think its certainly the sort of feature I'd love.

Compact digital camera roundup

People ask me all the time "Which camera should I buy?", by which they are normally referring to a point and shoot digital compact.

Over the summer there have been new compacts announced by pretty much all of the major manufacturers, so here's a summary of some of the best and a quick feature comparison.

I hasten to add, I haven't used any of these cameras, so make sure you read some proper reviews before making any purchasing decisions!

I've selected the newest, most comparable offerings from each manufacturer, so these are really the high-end of the ultra-compacts with the latest features, not your budget cameras.

So, here they are, in alphabetical order:

Canon Digital IXUS 850 IS


  • 7.1 megapixels
  • 2.5" LCD
  • 25.1mm thick
  • 640 x 480 @ 30 / 15fps movie mode
  • ISO 1600
  • 3.8x optical zoom
  • Face Detection / 9-point focus
  • SD / SDHC / MMC memory cards
  • Optical image stabilisation
  • Approx. 270 shots on one charge

Casio EXILIM Card EX S-770


  • 7.2 megapixels
  • 2.8" widescreen LCD
  • 17.3mm thick
  • 704 x 384 (Wide), 640 x 480 movie mode
  • ISO 800 (Anti Shake or High Sensitivity modes)
  • 3x optical zoom
  • 9 point multi focus
  • SD / SDHC / MMC memory cards
  • Anti-shake DSP
  • Approx. 200 shots on one charge

Nikon Coolpix S7c


  • 7.1 megapixels
  • 3.0" LCD
  • 21mm thick
  • 640 x 480 @ 30fps movie mode
  • ISO 1600
  • 3x optical zoom
  • Face-priority AF focus
  • SD memory cards
  • Vibration Reduction
  • WiFi connection
  • Approx. 200 shots on one charge

Pentax Optio S7


  • 7.0 megapixels
  • 2.5" LCD
  • 19.5mm thick
  • 640 x 480 @ 30 fps (DiVX) movie mode
  • ISO 400 (800/1600 at 4 MP)
  • 3x optical zoom
  • 5-point multi focus
  • SD / SDHC / MMC memory cards
  • Blur reduction mode
  • Approx. 180 shots on one charge

Sony CyberShot DSC-T10


  • 7.2 megapixels
  • 2.5" LCD
  • 20.6 thick
  • 640 x 480 @ 30fps movie mode
  • ISO 1000
  • 3x optical zoom
  • 5-point multi focus
  • Memory Stick Duo™ / Memory Stick Duo™ Pro memory cards
  • Optical image stabilisation
  • Approx. 250 shots on one charge

Comparison table

(click image for large, readable version!)




So, all of the cameras have about the same resolution sensors; similar sized, decently large screens; similar movie modes and at least some kind of anti-shake or blur reduction.

I think table shows that spec-wise the Canon is the leader with it's high ISO 1600 sensitivity, optical image stabilisation, 3.8x zoom, face detection auto-focus and 270 shots on one charge. However, it does sacrifice on it's size and weight and is the most chunky of the 5.

The smallest is the Casio at just 17mm thick, nearly 8mm thinner than the Canon, while still managing to pack a 2.8" 16:9 display (the only widescreen display amongst this bunch), a 3x zoom, the same resolution and good battery life. It also has a widescreen movie recording mode. Very impressive and if having the most ultra-compact camera is what you're after, this is the one.

The Nikon has the largest screen at 3" and is the only camera here with WiFi for transferring images to your computer or printer wirelessly (although that may be frustratingly slow when downloading a whole memory card). It also has the same high ISO 1600 sensitivity and face recognition auto-focus as the Canon but it is also the second thickest after the Canon and doesn't support the new SDHC memory card format.

The Pentax doesn't really best any of the others in any category but it isn't too far off in most areas. It's the second thinnest after the Casio but it has the worst battery life at only 180 shots and only manages 4 megapixels at it's high sensitivity setting (7 megapixels normally). Otherwise, it's pretty much in line with the others with the 2.5" LCD, 3x zoom and 640 x 480 30fps movie mode.

Finally, the Sony is similar to the Pentax but slightly thicker, it does though have the second best battery life and is the only one here, other than the Canon, to have proper optical image stabilisation. But one of my pet hates about Sony is their insistence on using their own memory card format. All the other cameras here use SD but the Sony uses Memory Stick Duo, so if you already have SD cards, you're going to have to buy all new Memory Stick Duo cards to use the Sony.

So, which one would I buy? In the absence of hands-on reviews, judging purely on the specs and what I know of previous cameras from these manufacturers, I would say if you don't mind the extra bit of bulk, the Canon will probably take the best pictures but if smaller is better, then the Casio could well be the one. I would also consider the Nikon as it's possibly the best all round compromise between features and size.

I definitely recommend you try and find some decent reviews of these cameras before buying one though and as always, go into Jessops or something, have a look and try them out as well.

dpreview.com is always a good place to find excellent reviews.

Canon 400D preview

Digital Photography Review have just posted a great preview of the new Canon 400D, a 10 megapixel DSLR.

It's typically thorough and detailed. Definitely a recommended read if you are considering getting one:

http://www.dpreview.com/articles/canoneos400d/

Being an owner of a 350D for less than a year, unfortunately I can't justify the purchase but it does sound like it's a great update to Canon's popular entry-level DSLR.

New Canon 400D 10.1 megapixel DSLR

Update: Canon today confirmed the 400D (XTi in the US), specs as below.

Looks like Canon are releasing a new DSLR, the 400D. It cropped up on the Canon China site for a while but appears to have been removed now.

The specs are as follows:

  • 10.1 megapixel CMOS
  • 2.5-inch LCD
  • 9 point focus system
  • Fast 0.2 second start-up time
  • 3fps 27 frame burst
  • 1600 ISO setting
  • DIGIC II processor
  • Integrated Self Cleaning Sensor Unit
  • Software to delete any dust left over
Canon certainly needed to move to counter Nikon's new D80 and this successor to the 350D looks like a worthy update.

Nikon D80 10.2 megapixel SLR

The replacement for the very successful D70/D70s has finally been announced today. The D80 features a new high resolution 10.2 megapixel CCD, improved 11 area auto-focus, a larger and brighter 2.5 inch LCD display, powerful new image processing and metering, configurable auto and high ISO settings and other improvements, many of which are passed down from the pro level cameras.

They've also switched from Compact Flash to SD/SD-HC memory card support with the new camera, leaving Compact Flash for the pros. The D80 is also a bit smaller and lighter than the D70s.

Overall it looks like a great evolution of the D70s and is no doubt set to be as popular. Digital Photograhy review have a typically excellent, detailed preview of the camera (that they've been using for a couple of weeks already, lucky them).

Looks like Canon have some catching up to do, I wonder how long it will be before we see a new version of the 350D?
