Well, I do know the model name of my latest camera. It's a 5D Mark3. It was delivered last Friday and other than charging the battery, I haven't touched it yet...hasn't had a lens on it, hasn't had the shutter fired and I haven't even looked through the viewfinder. I'll get around to it in time but for the moment there are other priorities.
I take photographs virtually every day and have for the last 28 years or so. As much as I love what I do, it's still work and as cliche as it likely sounds, the hardware is just a tool, so I don't personally fault somebody for not knowing or caring about the specific model name...at the end of the day, I'm far more interested in looking at photographs than at cameras (as cool as they are!).
