So this forum has the most discussion if you at the counts underneath it. Second is the X T1, X T2, X T10 & X T20. If you had asked me to guess, I would have guessed the "T" line would have had the most participation as it is the least "niche" camera category. A new camera newbie is more likely to get the T20 than the 100F. So why is the niche camera groupies getting the most action?
