Carlos I am sure you will soon get a huge pile of replies specifically relating to the *ist D and Ds cameras, but if I may pre-empt those, in my experience, DSLRs allow both 'Single Shot' and 'AI Servo' or 'Continuous' modes. In Single Shot, you half press the shutter, it focuses, locks on, beeps, and you can then fire. In AI Servo, you half press and the camera focusses, but you can fire at any time for as long as the camera will allow. You can even fire before the thing has focussed. I came to digital single lens reflex cameras directly from the LX. Hence, using AF, I tried te Single Shot mode once. I have never used it since. To me, it is alien. 'The camera will not allow me to release the shutter because it has not yet focussed' ?? Whatever next? The camera will not allow me to fire because I haven't framed properly?? Bollocks to that! I only ever use AI Servo, and Continuous, and guess what - it's just like my beloved LX and MX cameras :-)
Thanks for your answer, Cotty. I started using AF SLRs back in 1988, with the SFX, and after 6 AF SLRs I am used to AF-single and AF-Continuous. Both of them have their strengths and weaknesses, as you have pointed out. The *ist DS has only the AF-single mode, and it can switch to AF continuous if you use the "Action" mode. This is its weakest point in my view, the deliberate choice Pentax made to limit the user's choices in AF. But after I saw the two different versions of the manual about AF in continuous shooting, I really want to know which is right. There are some things about the DS I like, such as the bigger screen, better grip, USB 2.0, but there are also several advantages in choosing the D, like the two separate dials for Av and Tv, user-selectable continuous AF in all exposure modes...
Thanks again, Carlos
