I hate these questions. I believe that this is mostly because I tend to find them early in the morning before I go to sleep and, therefore, have trouble completely collecting my thoughts on the subject. But here goes nothing anyway.
What is technically important to me? Hm. This could take a while.
When I was first introduced to film photography back when I was young (not that I'm old now, of course), nothing mattered as long as I could take a picture. I was too young then to understand about bokeh and aperture and shutter speed and other more technical things...I just wanted something to show friends and family. I remember being interested in my Uncle's Pentax K1000 almost since I CAN remember...but never asking if I could use it because it seemed intimidating to me. All the cameras I had before I was 18 were all point and shoots of various makes and models, some of them digital.
Then I bought a Minolta QTsi.
This was the first (and last, funnily enough) new camera I'd ever bought myself. It was the first (and last) autofocus camera I had. It was the first (and last) camera I had with a zoom lens. It was my first SLR. It was my first time handling an SLR. And this is where my research into film speed, aperture, and shutter speed began.
The QTsi was a horrible camera with almost no manual controls. It was essentially a point and shoot with interchangable lenses. I regretted that purchase almost as soon as I made it, and I sold the camera no more than 8 months after getting it for $100 to my Dad. This is when my real journey began.
I got on Ebay and found myself a Nikon FE and a 50mm f/1.4 AI Nikkor. I got the kit for less than $200 and was quite pleased with myself. I started using the camera and, when I got my first roll of film back, I was astounded. Something had been missing from my photos before this. Something important. They had no real passion. That roll, though, was full to 24 exposures of photos where *I* had to calculate exposure, *I* had to set the aperture, *I* had to set shutter speed, and *I* had to focus the lens. I had no trouble focusing on whatever I wanted, center of the frame or not. I didn't have to turn off autofocus because there wasn't any. It did have an auto exposure mode, but that was always turned off. This camera was my pride and joy and the first camera I felt comfortable using.
The journey took me then to rangefinders. It was a logical progression because I was interested in street shooting and needed something smaller and quieter to carry around with me than an SLR with a big lens. My first rangefinder was the Canonet 28 I still have...auto exposure but manual focus. I loved it and soon found myself looking for an interchangable lens camera. Someone stepped up and let me borrow the Canon P that I now have, which he later let me take from him.
The Canon P was the start of a long spiral down into obsessing about technical merit of certain lenses. Is this one better than the other? How's the bokeh on this one? Should I buy this or this? I was so obsessed that I sold my Canon 50/1.8 to fund something else that I didn't even get.
I had thought for a long time about buying a Leica next year. I was all set and had the decision made these six months in advance, but then I had an epiphany that I should have had long ago: what the bloody hell is wrong with my Canon P? It is the perfect camera for me and it has proven itself to me again and again. Why should I switch from something I know will perform for me day in and day out? The Leica lust has ceased. I'm finally at peace in that way.
However, I know that my photos aren't at there best because of all this screwing around and testing things. I'm done with testing. I'm through with worrying so much about the technical merits of my glass and I'm done testing 50-thousand things trying to make myself happier. I'm buying myself some Voigtlander glass next year and making that the end of my gear acquisition for a while. The end of my GAS has finally come to pass.
But what does this have to do with what I want in a camera or lens? Everything.
I've learned to be happy with what I have, imperfect as it is. I've learned that sharpness and bokeh are not the only things that are important in photography. I've learned to focus more on the composition of my photos and I've learned to use the DOF scale so that I'm not always shooting with 2-foot shallow DOF. I've learned that choosing the right developer can improve your photography by quite a bit if you had problems with certain things like shadow detail and graininess before. I've learned that experimentation can lend itself to bettering your photography by a large margin. I've learned not to be so anal in my focusing and that a little camera shake doesn't always hurt a photo.
In my mind, the best photos are taken by those who care more about composition than technical merit. I've seen excellent photos shot with pinhole cameras which I liked better than a portrait shot by a pro with a Leica and a Summicron lens.
It isn't your equipment, but how you use it. I believe this whole-heartedly. If you have no vision and no direction to take your photography it isn't going to be good no matter what you do. Photography is only limited by your own vision and imagination.
I'm going to stop now. I think lack of sleep has finally caught up with me.
