Once I was on a trip and friend of mine was very interested in my camera ... well until the moment she discovered that with that lens she cannot zoom at all. "What is it good for when you cannot zoom?" I tried to explain and then shook her head because she couldn't understand the cost and size of this lens when it can't do what she wants.
Even more they shook their heads when I tell them, that every photo needs to be postprocessed (let's say only exported to jpg), they are used to do things conveniently. (And I'm not even mentioning panorama stitching or portrait retouching and time spent on this)
If it makes you feel any better, I find a lot of people expect all dedicated cameras to have zoom capability. I picked up a EOS-M during a fire-sale with the 22 f/2. I handed it to my wife and to a friend to try out on separate occasions. They both asked me how to make it zoom. Suffice it to say, I ended up picking up a white box EOS-M 18-55 for the wife to use. I use the 22 f/2.
When some of my friends first saw the 70-200 II, they thought it had a much longer FL than it did because it was so large/heavy. I use the 70-200 II a lot when my girls are playing soccer, and I've had the usual comments from random strangers like "Wow, that is some lens!" And my default reply, "Yes, it is!" It surprises me that there aren't more parents with better cameras. After all, I see higher quality lenses/camera combinations at berry farms/apple orchards than I see at the kids' games.
I've actually found it to be more awkward interacting with parents when we're watching our kids' team play together. You can hear their frustration trying to capture their kids on phones/cameras wanting to get a good pic but are unable to due to equipment limitations, technique or position issues. And you know that they are wondering if you are getting any good shots with your camera, but they are too shy to ask. I used to take pics exclusively of my kids, but I've come around to taking more shots during the scrimmages of their teammates too. I then send the parents links to the SmugMug galleries and the most common response I get to those pictures is one of gratefulness. That, and the awkwardness is now gone. It's much easier talking to other parents and I have the freedom to take pictures however I want.
