I went to the grand-am rolex race yesterday at lime rock park in CT. It's a gathering of about 10000+ race fans of above average affluence. We can wander about anywhere except the track and pit line during the race. I carried a DSLR with a 300/2.8, a DSLR with a smaller kit lens, and a rolleiflex (an older automat mx). As the paddock area was open at all times, there was always interesting prep and repair activities going.
I had at least 4 of the official orange vested photographers come up and give some credit for using film in a good film camera. I mentioned the film is better than ever and I like shooting some B&W. A couple other fans came up and talked about it too. While I was checking out a ferarri p4, someone came up and mentioned his mother had a camera like that and it's been a long time since he's seen it. I suggested he use it because it can do a good job. Since about every other person there had a DSLR (the other half had phone-cameras), people'd pay attention to what I shot since I was the odd guy out. I'd find an unusual view or position and make a photo and after moving on, a couple other people would be right there checking out the spot.
I only had one person (probably a gearhead of some sort) who was working a booth ask about my 300mm lens. To walk around with a newish DSLR and an expensive telephoto or tele-zoom is not unusual. It's unusual, but kinda nice to blend right in aiming and shooting a big dslr with a 300/2.8 on it.
I shot 5 rolls of 120 TMY2 and I can't wait to process them. (I also shot 400 frames on the DSLRs, for those interested in the comparison of shooting styles)
