Amateur Photographer - - Your Letters -

Gone are the days when fo­cus­ing was sim­ply achieved with Fres­nel screens, split im­ages and merely turn­ing the fo­cus ring on the lens. You knew what you were fo­cus­ing on and whether your sub­ject was in fo­cus.

Now, the cam­era that I own has – apart from a man­ual fo­cus set­ting – aut­o­fo­cus sin­gle and con­tin­u­ous, static and dy­namic, 1 field, 9 field and multi-field of 37 or 49 fields, oh and not for­get­ting face recog­ni­tion. I am not quite sure which op­tions work with which but there must, in the­ory, be over two dozen al­ter­na­tives from which to choose.

My guess is that there are prob­a­bly only a hand­ful of the avail­able op­tions that are use­ful, but I have no idea which and for what pur­pose! I have been un­able to find any­thing that ex­plains to me which op­tions are best for which cir­cum­stances, and as such I tend not to use the tech­nol­ogy be­cause I am never cer­tain as to what the cam­era is try­ing to do.

I sus­pect that I am not alone in this sit­u­a­tion and I won­der if you could pub­lish an ar­ti­cle that ex­plains a bit about what the cam­era is try­ing to do in the dif­fer­ent al­ter­na­tives. You could also in­clude a sim­ple ta­ble of which com­bi­na­tion of set­tings to use in which cir­cum­stances. Given that the cam­era has all these ca­pa­bil­i­ties, I would like to be able to use them with con­fi­dence. Richard Sharp
