“Till its been stolen I was very happy to have this...”

★★★★★

written by on 17/08/2008

Till its been stolen I was very happy to have this cam. It can be always together with me wherever I travel. So compact and powefull. Easy to carry. Very rigid and unexpectable performance when compared to its size.

f2.8 so 80-1600 (also 3200 in scenes) 15 sec posing. (hope it was 30 at least)

“I used to own a rather splendid Nikon Coolpix 8700 ...”

★★★★★

written by Terence Wass on 02/03/2007

I used to own a rather splendid Nikon Coolpix 8700 until I left it on a train bound for Liverpool and never saw it again.
The Nikon took breathtaking photos but had two drawbacks.
1.It was heavy. After wearing it around the neck for more than an hour I needed a hot bath and a massage.
2. It was bulky. This is why it was in a bag and not in my pocket. This is why it was stolen.
Don't worry, this is not a review of the Nikon, it is a review of the Canon Powershot G7.
I take a lot of photos for work (I'm a Web Designer) and needed a camera in a hurry.
I chose this replacement because of its' compact size, its' relatively low weight and its' manual controls.

I had read some good reviews and each seemed to be either aimed at professional photographers or were a short overview.
I tend to agree with the review by "Big H" on this site, but if you want some more information aimed at the average snapper, read on.

Out of the box
As you would expect, everything you need to get going is included:
An impossibly small memory card.
Battery with charger
Comprehensive manual on CD and quick guides on paper
Connection leads for your computer
The camera (phew!)

I'll start with the memory card. At 32MB it's only capable of storing about 5 or 6 full sized photos, which you might initially think is pretty useless. Well, not quite.
This does at least give you the chance to play with the camera on day one.
If they provided a card of respectable size it would put the price up and the people who already owned a decent memory card would be annoyed.
My old Nikon was supplied with no memory card at all which added 3 days of waiting to my time before I could use the damned thing. Sensible thinking on Canon's part.

The battery takes 1.5 hours for the first charge which just about gives you time to have a read through the manual. I recommend copying the CD directory structure to a temporary folder on your hard drive to prevent you having to wait for the CD to wind up every time you turn a page.

The camera.

Design wise there are some good features and some bad features.

Buttons
Canon have often used thumb wheels for selections on their cameras and the G7 is no exception. One wheel allows you to quickly select shooting mode and another allows you to select ISO speed (more on that later on).
Thumbs-up to thumbwheels, I like them a lot.
The front and sides of the G7 are button free. The shutter release button is on the top with the power button and main tumbwheels and the rest are crammed on the back next to the screen.
There are a total of twelve buttons on the back. That's right, twelve. There is also another thumbwheel there.
Some of these twelve double up depending on which mode the camera is in and at first glance you think "Whoah, steady!" but in use, I found them a doodle to use; it really was a case of guessing what to press and getting it right almost every time.

One drawback is the lack of a reasonable grip. The reason for this design decision is probably to keep the unit flat so that it can fit into a shirt pocket.
The net result is that you will end up accidentally pressing buttons while lining up your shots for the first hour or so until you figure out a way to grip it around the sides while using it. It feels odd for a while but it can be done.

Shutter release
A surprising omission is the lack of connection for a shutter release cable.
Surprising because it would only mean the addition of a threaded hole in the button top.
Even on a tripod pressing the shutter release button can cause enough shake to ruin the shot, particularly on a lightweight tripod.
Fortunately this camera has a lens shift stabiliser that actually works really well.
The tactile feel of the shutter release button is a bit odd. A half-press is pretty much a full depression with the last "half" being a solid click. It's a bit like a new clutch, any self respecting bloke will get used to it in two seconds. Can't say about the ladies really, my wife doesn't want to touch the camera for fear of damaging it irreparably.
I shall not argue with her; partly because I like the camera but mainly because it would be a waste of time.

Screen. B.B.B.
Big, Bright, Beautiful . and a magnet for fingerprints.
It has a special anti-reflective coating, bazillions of pixels and no matter what lighting conditions you're in, you can see it just fine. It cannot be tilted or swivelled - that can be a pain when taking shots from the back of a crowd. Enough said.

Other features.
The zoom is controlled using a rocker switch and not by turning the barrel. I wish this camera had the same zoom control as the Fuji Finepix S6500FD (which was very nearly the camera I ended up buying, mainly for that reason) but it doesn't. It's something I will just have to live with. The zoom is reasonable at 6x optical and then there is some digital zoom on top of that.
In the olden days, digital zoom used to be about as useful as a rubber chisel; totally useless.

In these modern days of complex electrickery the digital zoom is rather good. When you take one with the G7, is does some clever stuff that delivers a reasonable image (though not perfect). The digital zoom is better than I had hoped but is probably standard for a modern day digital camera.

Manual focus tries a bit harder though. When you select manual (not available in Auto mode) the centre portion of the image is magnified to help you get it right and focus is set using the thumbwheel on the back of the camera. Even though the focus control is not on a ring on the lens, the setup is pretty fast and accurate. Nicely done.


"Gimme that old hot shoe"
Like my old Canon film camera, the G7 has a flashgun shoe. If you have one (and I do, from my old Canon) you can plug your serious flashgun onto the top of the camera for all those external flash benefits. Another plus point.


Using the camera
This camera goes from Off to Ready in about a second.
Depending on the mode employed it will take the picture a fraction of a second after you hit the button.
With a nice fast card in there, we're still talking a fraction of a second for storage of a full size image.
It goes from on to off in about a second too.

Picture the scene. September 11th and our G7 owner looks into the sky and says "No way", pulls the G7 from his shirt pocket, powers it up and takes loads of 10mega pixel shots of this moment in history as it happens.
"Best get the hell out of here" he thinks and runs away only to turn round a minute later and take some more photos of first tower as it comes crashing down onto the Coolpix owner who is still waiting for his camera to get it's arse into gear.

Speed is important and this camera has it. Admittedly, there is lag with this unit under certain circumstances that could cheese you off, like "full auto everything" with flash required (that hasn't warmed up yet) and can take almost a second. These are all things you can get round by using the camera properly and buying a flashgun.

Most importantly - the pictures.
The pictures it takes are certainly big enough (3648x2736px) which means you may find some decent photos within your photos. Could you print out posters? Yeah.
This size does mean that the images will happily munch away at your memory card like a heard of starved goats however.

Where is RAW mode? It just isn't there. I've looked. Twice. Even behind the fridge and can't find it.
In the past I have used RAW mode very occasionally and it does have it's benefits; Image quality IS better, particularly for reduction of colour banding on sky shots and overall colour rendition, but to be honest, unless you're a real pro, lack of RAW isn't the end of the world and besides, you would probably only fit one RAW image on the supplied memory card!

The exposure is normally well calculated but most folk who spend upwards of 300 pounds on a camera should know who to use exposure lock and stops anyway.
The colour balance seems to cope fairly well indoor and out (with more emphasis on the "out", incandescent and tungsten look a little bit warm - but you can tinker with that on the camera or in your paint package).

Handshake is not quite a thing of the past, but the stabiliser is a big help and the images are sharp from edge to edge.
Macro mode is very good too, like looking at a fly on the end of your nose without much "goldfish bowl" effect.
In fact, you have to put in a bit of effort to take a "bin shot". Well okay, your subject may be dull, but this camera will bend over backwards to capture it in the best possible way. Even the built in flash isn't too harsh.
So where are the issues?

Let's have a look at the ISO settings and noise.
I imagine that because the CCD is of a high megapixel rating and that it is a small (in physical size) chip, it is more susceptible to noise than some others.
That would be my guess looking at the results.

ISO 80 to 200, no problems really, certainly no worse than some more expensive cameras I've used.
ISO 400 - hello, what's this? Starting to look just ever-so-slightly grainy.
ISO 800 - Oh dear, that looks a bit ill.
ISO 1600 - forget it, this is a bin shot
ISO 3200? I didn't even look at this setting.

In reality, the ISO modes are worse but probably not MUCH worse than any other camera, but above 800 is just a joke.
Terry's Top Tip? Keep your ISO setting below 800 - and with this camera you can - the stabiliser will let you use slower shutter speeds without blur (unless your subject is moving) and you can set a reasonably wide aperture (2.8). Just try, it shouldn't be so hard to use ISO 400 or lower should it?
At lower ISO settings I can't really fault the image quality and in a way it's good that the camera doesn't smooth away all the detail with it's onboard noise filter, at least you can choose whether or not to smooth it up a bit in your paint package and you can be selective on the areas you touch up.
I tried to think of any times I would need to use ISO 1600.
Taking yet another shot of a full moon without a tracking system?
Capturing a pack of lions in the dark without the flash alerting them to my tasty presence?
If you need to use a high ISO speed on a regular basis, this is probably not the camera for you, I think you'll need to spend some more money.

The videos this thing can shoot are impressive.
You can go up to 1024x768 at 15fps. That's a big frame size if a bit jerky.

640x480 at 30fps is the next one down. This is smooth and is not too far short of DVD quality (720x576 for us Limeys). The zoom can be used while recording and best of all; there isn't any of this "15 second maximum duration" nonsense like with most cameras; on the G7, you can keep shooting until you fill your memory card.
Think about that just before you go to sleep tonight, I may sell my TRV11E now I have the G7.
If you need to , you can use the G7 as a voice recorder as it will make WAV files with it's built in microphone. It might be useful one day.

Summary.
The G7 is a shirt pocket camera that takes big shots really quickly. Auto mode is idiot proof and there is full manual control for you creative types. For the money (about 300 pounds) it's blisteringly quick, very flexible and loaded with features.
Just stick to the lower end of the ISO range and you'll love it.

Best of all? Your less likely to leave it on the train!

“Bought as back up to my D100 which I use a lot for...”

★★★★☆

written by BigH on 03/12/2006

Bought as back up to my D100 which I use a lot for studio work hence the hot shoe is invaluable. It's now my go everywhere camera, living in a small bum bag!
I also like the OIS which is brilliant.
In retrospect may have been better waiting for the Nikon D40? But I do like a small camera just to be with me at all times and dSLRs don't quite suit that.
Not convinced the 10MP is worth having though since the results aren't any better than the Fuji F10 Digital Camera I had.

I'll put some images up on my web site www.howardleigh.me.uk

You have summed up the main points about this camera in a spot on fashion. Nice job.
