Remember that the vast majority (around 95%) of people never buy another lens after their original purchase of a DSLR.
Please provide a legitimate survey/research to this fact.
I believe if you are talking CAMERAS as a whole, that may be true since Point and Shoots do not take other lenses (though some will take adapters for macro, etc)
Empirically, the stat in my own experience is utter bulls^&*t.
For myself, multiple bodies and lenses.
My father, more a hobbiest, multiple lenses
My sister, more to take pics of the kids, even with a T5i she has 3 lenses
A Doctor friend - has about 4 lenses
Another racing friend - 4 lenses
Ironically, my sister and myself are the only Canon shooters in that crowd, the rest Nikon, but I can't think of a person I know casually who owns a DSLR body and does not own multiple lenses
I am excluding others I know who are professional or semi-Professional (actually on that side I know about 75% Canon shooters). If I go into that realm, of those I personally know, I am at about 65 - 70
So statistically, as I approach 100 people (at least 70% the way there) I cannot think of one person I know or have met who owns a Dslr and does not have at least one more lense, and the average number is somewhere between 3 and 4 (I am at 7 and soon to be
I deliberately tried to go into thinking about more family, non photographers, non hobbiest, but, those folks tended to break into more point and shoot or camera phone.
I would be more surprised if 50% of those who buy a DSLR do not by at least one additional lens with 12 months of getting their camera.
I have a proposition for you...
Lets do this.
For every DSLR owner you find that has owned their camera more than a year and has only used a kit lens, I will give you $1
For every DSLR owner I find that has owned their camera and have purchased at least one or more lenses beyond what came with that camera (including those who purchased body only because they wanted a better lens ) you will give me $20.
By your statistics, this gives me a slight edge of $5 per $100
Professional and Hobbyiest shooters can be included.
I would like to also give a warning... if you look at polls like this: http://digital-photography-school.com/how-many-lenses-do-you-own-poll/
9% say they do not own DSLRs
9% say they only own one lens
23% own 2
59% own 3 or more.
Out of 36244
3247 are excluded because they do not own a DSLR
Congratulations, 3263 own only one lens.. I owe you $3263... but
29522 own more than one lens.... OUCH
You owe me $590,440, minus the $3263 I owe you...
I will give you a little break and lets just call it $585,000
By that poll, about 10% own only a kit lens, and in fact 3x as many people own 5 or more lenses.
And given who you are... I would prefer CASH.
