I bought this for my daughter small SLR with 18-270mmm tamron the first contact we are surprised by the larger size hardly some bridges, especially if you have big fingers like me, but you get used quickly and getting started is easy; the selector M / A has a third position for the video (very good idea); AF in video surveillance is good but for objects of a certain size (persons) by cons for small birds in the foliage is not even worth trying, so disable it on the objective; for the rest it is a real 18MP DSLR with all its benefits without the weight and quality of the photos are quite honorable; only minus the small battery that has not a huge autonomy (you must buy a backup); this device is advisable really is a thousand times better than the most advanced bridges for little more expensive (depending on which lens you take); If I found a problem or an inconvenience, I would change this review to inform you
