Can we stop with the f-stop c**p? I'm putting this in my pet peeves in the pet peeve thread.

Shall we instead discuss the crop magnification factor?  :p

Oooh yes, let's. Especially as it relates to macro and shooting 1:1 and whether I can get more DOF with a crop, thus it's better for macro. Also more subject distance since a 100mm macro is effectively a 160mm macro. So I can get more magnification with greater subject distance and more DOF - wooohooo.


And because it is the internet....

Please don't anyone think I am being serious here.:lol:

2) On the above lens which is not a zoom lens, does it take much practice to be able to find a moving subject (such as a bird in flight) in the Viewfinder? Hints on how to do it?

It was difficult for me at first to find a fighter jet with a 400mm, let alone a bird. It gets easier with practice, as you gain the "muscle memory" needed and you intuitively know where the camera is pointing.

Yes, practice. I recall in Basic Training, they taught how to 'shoot from the hip' because the jungle conflicts were full of surprises that did not afford time to raise a rifle to your shoulder and take careful aim when your position is about to be overrun by an enemy fairly close. So they gave us BB guns, paired us with a partner, and the partner would toss a metal disk up into the air and the other guy would 'shoot from the hip' (not truly hip position!) to practice the technique. You would be surprised at the high percentage of hits that you could achieve! Not dissimilar from raising a camera + long lens up to find a bird in the viewfinder...practice.

We're a bit short on jungles here. But there have been battles. The westernmost battle of the Civil war was fought at Picacho Peak, about 110 miles west northwest of where I am.

Nowadays, we leave it to the rattlesnakes and scorpions to give visitors a little excitement.

The Tour de Tucson is this Saturday, and we expect lots of rain. That'll be fun for the riders.
