In the past I have been guilty of breaking one of the most sacred rules of being-a-photographer by not having a camera on my person at all times. If I'm not working and I don't have to carry a bag filled with kit I often choose to leave the camera at home and risk missing the shot of my life. Although I do get a kind of perverse thrill from this recklessness, it's the freedom from faff that leads me to do it. Having a camera around one's neck is a pain, having it in a bag is a bother and I've never had a pocket-sized camera that I really enjoyed using and could get good pictures from. But times change and technology is a wonderful thing and I have now found a camera that slips neatly into my jacket, is a joy to use and makes great images. But first let me discuss it's compact predecessors, each good in some way but none as complete.
My first compact was a Fuji DL Super Mini back in '96. Very small and nicely made, it was nicknamed the sardine tin because of it's shape and metal housing. The lens was good enough to produce near-SLR quality prints but in the end it had winder problems and had to be retired. Here's an old image I shot through the window of a deli with it: 
I replaced the Fuji with a Ricoh GR1, which was the other hot compact of the day that has since evolved into a near-identical digital versions. The Ricoh had aperture priority and exposure compensation dials on the top panel allowing a fair degree of manual control and an understated matt-black-ness that whispered "I'm a discerning pro, incognito". I don't know if I was unlucky but this camera suffered from winder problems too and I went through a few replacements on warranty until I reluctantly gave up and moved on. Here's a Ricoh shot: 
After the Ricoh(s) died I eschewed compacts for a little while and tried to carry my Leica around but although I got images I often didn't take it out. It's is a measure of my lack of dedication to my craft that even with the good fortune to have the preeminent tool for street photography at my disposal, a Leica rangefinder, I still neglected to carry a camera at all times. The fact is, I find even a Leica is a bother. But no excuses, I am a sinner and when I'm called to account by the Great Picture Editor I know for sure that the pictures I've missed will outnumber the pictures I've captured. Still time to redeem myself I hope...
When I went on honeymoon to Japan in 2005 I took my Leica, and my wife and I borrowed a digital Ixus. The Leica took all the most beautiful shots of the trip but the Ixus got used more and so, on the way back through Tokyo, I bought my first digital compact, the just-released Panasonic Lumix DMC LX1. Back in 2005 I was still shooting on film so this was my first digital camera and an introduction to the pros and cons of the new medium. I pretty much bought it on the strength of the Leitz lens and I did get some OK images:

The LX1 had a few features I really liked, image stabilization, a choice of formats and control over flash levels. There were quite a lot of manual controls, even manual focus but this was clunky to use. It still felt like I was compromising a lot on image quality and usability for the sake of convenience and what I really wanted was a smaller, more compact Leica, with manual controls and a peachy lens.
In the meantime I had taken the plunge and gone digital, trading in my much loved workhorse, a Nikon F5, and a ton of kit for a Canon 5D, so when I started looking around for a replacement compact I was inclined towards the Canon G9, which would allow me to use my new 580EX speedlight. I should have loved the G9, it's a very capable camera with a good blend of features from DSLRs and compacts and it will fit into a jacket pocket, though it's a bit bulky. I should have loved it but I didn't, it wasn't fun, it felt like a less user-friendly, slightly crappier, smaller version of my 5D. Perhaps the chemistry was wrong? Anyway here's two pictures from that rather troubled relationship:

At least now I know what I want from a compact camera:
- Easy and fun to use so that I want to take it everywhere
- Image quality has to be good enough that when you take a really nice image you aren't sad you didn't have a better camera with you
- Fully manual exposure controls
- Fast lens and low noise
- It has to lead you to experiment and produce surprises
- Fits in the back pocket of a pair of jeans
Not much to ask.
And here is my new love, the Canon S95. I'm not going to review it, you can find plenty of exhaustive reviews elsewhere, but it does all the above with style and ease. I particularly like the fact that you can choose to shoot in square format. This might seem a slightly daft gimmick, you can always crop later right? But I love shooting square format, not cropping square format, there is a difference.
I'm currently working on two projects specifically tailored to the abilities of the S95 and now, when I leave the house I pat myself down for my keys, my phone and my camera. Perhaps I will finally be able to keep that sacred rule.
