First of all, don't refer to me in your post......I do much
research and have been an active member of these forums for over
two years.
If you didn't want people to infer that you didn't do your homework, then you mislead readers by jumping to the defense of one who admitted to having done just that, and implied it even further with your opening statement:
"I think we need to remember that the large majority of digital camera buyers do NOT read these forums or reviews before they buy." That's sufficient cause for any reasonable person to conclude that you count yourself among "the large majority."
I have both the Nikon 5700 and the Minolta D7Hi. And
guess what? The Minolta performs MUCH better focusing in low
light......which is all I was saying, whether you like that or not.
Of course it does. It's zoom is only equivalent to 200mm and it has a max aperture at full zoom of f/3.5. Compare that to the Nikon with 280mm and f/4.2. Back off the zoom on the Nikon to comparable zoom and aperture, and you'll have similar results, if not better. It is, after all, the amount of light reflected off the subject and entering the lens that is the most important factor for automatic focus. The "problem" isn't what the camera doesn't have, but what it does have.
Here's something you probably haven't considered: so what if it did have AF assist? It might be able to lock on a subject, but if you still have camera shake, what good is it? Not getting focus is a warning, just like a flashing green light, shutter or aperture indicator--the camera is communicating with you. By the same token, are you aware that stabilizing the camera in those low light/contrast situations will get focus lock, will get it a whole lot quicker, and will prevent the motion blur resulting from camera shake?
This isn't a workaround. It's the necessary technique for using a very long lens; The high maginification exaggerates everything, not just the optics. It is subject to physical laws. i.e., the sciences of physics and optics. The fact that the lens is lightweight and small may be deceiving, but the laws still applly.
As for your premise that "the large majority of digital camera buyers do NOT read these forums or reviews before they buy," I would strongly disagree. I think you will find that most people interested in buying a $1000 camera do indeed spend a good deal of time reading reviews---mostly in magazines and more than likely on-line as well. I don't know how you arrived at that statement, and I"ll humbly concede if you show me the statistics to prove it. But the huge sales figures for the annual buyers' guides to consumer cameras and electronics should give you some idea of the enormous number of people who are doing the research.
So quit with the overly defensive responses...
No, my position is not defensive, merely logical. Sorry you took offense, but I'm just telling it like it is. I have no emotional stake in the argument. I do, however, happen to be tired of people bashing the camera when it's obvious they don't truly understand it: AF assist is unnecessary at 200mm equivalent and below. Above 200mm, it won't help. Only a tripod will help.
