[QUOTE="Love Nikon, post: 432554, member: 38179"] I previouly commented on poor AF performance particularly in AF-S mode on the D7100 . Many seem to think that its a matter or adjustment but an analysis of the modules gives the reason . D7100/7200 at f8 1 cross sensor in use D610/D7000 at f8/5.6 7 cross sensors in use D750/D8xx at f8 11 cross sensors in use So we see why in my case an upgrade from a D7000 to a D7100 was such a disaster for me and that a move to a D7200 would make no improvement. With the bottom two cameras in lower light and low contrast the assisting sensors can find sufficient detail to make a focus but the poor old 7100 cannot . Where to go from here ?? [URL="http://shop.ebay.co.uk/?_nkw=d610"]D610[/URL] but then I must buy two and two 28-300mm. This is not good for cashflow. Clearly the marketing value of 51 points outweighs the functionality of the 39 system. I feel very disapointed ..I pay for an upgrade and get a downgrade but I dont feel a Canon comming on .
