>>4124064These SLT cameras had faster burst speeds than mirrorless, had affordable 10 fps with high mp, when the other two you had to buy more expensive camera to get that speed. Also (on paper) you had constant AF I believe, so (on paper) you could track better than regular SLR.
Honestly, I think only real issue (subjective) I can think was that it didn't have OVF. Many mirrorless don't have it either, but OVF is something that I think is really great, especially on FF SLR cameras where the viewfinder is big.
