[QUOTE="Stoshowicz, post: 355435, member: 31397"] That sounds like nice reasonable methodology , Im using a 70-300 vr lens which , looking at my static pix , is spot on though,, most of my subjects are small , and so I dont want to move the front-back focus adjustment at all. In order to get enough shutterspeed and aperture , I often have to boost the Iso topping out at 800. The issue I'm trying to improve ,, becomes complicated , as the dragonfly gets closer I get better detail , but I've got to be super quick to acquire focus, and its just difficult to get a clear grasp of the intricacies of the various auotofocus systems . Its just confusing.. and one really needs the camera to help out. For instance -I was reading on luminous landscape Mr Koerners post , where he said, that [I]"Setting multiple AF sensors with the focus tracking lock on set to 'off' will defeat the camera's dynamic AF capabilities - multiple AF sensors are designed to work with long, short, or normal settings to keep contact with the subject. If you are using a single AF sensor on a single subject, OFF may be appropriate under some circumstances - if you loose contact with the subject however the AF will instantaneously jump in most cases to the background." [/I]and the D51 mode might be more prone to this.And I just dont know if this is meaning single point D51 , or if its AF-S single point.. so I cant say if this agrees with the earlier post by nickt , or disagrees with it- regarding the autofocus lock. Another issue that pops up is, 'what exactly is the delay that might happen using 51point mode versus nine point mode?' Wouldn't [I]more[/I] autofocus points be an improvement? Simply put ... The recipe Id like to know is what combo acquires the small moving target fastest , locks on and holds on to it best , for the fraction of a second until the shutter completes its closure. Uggh :) [/QUOTE]
