r13, you know very well that i've been more than generous to the local photography club (a very happy 7th grader thanks you for the 18-55).

i have a really huge pile of these and it would definitely take more than two trunk-full trips on my car to move them. it's too much hassle. the shot you see is as much as i can carry to pose them for a shot.

This negates much of the magic of having instant manual focus override, since you may not have enough precision using only the ground glass to focus at f/1.4. (The ground glass only shows the view at about f/2.8, not at f/1.4.)

Nikon lenses work correctly, which means that any time you grab the manual focus ring with the shutter pressed halfway, even with the camera left in autofocus mode, the focus confirmation light works properly. With this Sigma lens, the light locks up in either on or off, wherever it was when you grabbed the ring.

Creepier, after you've grabbed the manual focus ring in AF-C (continuous) mode, the Sigma will revert to AF mode instead of locking the manual focus properly.

Correct operation, which is what you get with real Nikon lenses, is that even if you're in AF-C mode and grab the manual focus ring that the focus stays set where you put it until you release and retap the shutter buton halfway.

This gets worse on my D40, since my D40 has no external AF/MF switch. On the D40 I need to go into a menu to select manual focus, and to select between single (S) or continuous (C) or automatic selection (AF-A) AF modes. Therefore, when I grab the manual focus ring on my D40 in the D40's default AF-A mode, if the subject is not moving I can set focus manually (still without a focus confirmation light) on the Sigma 30mm f/1.4. Heaven help me if the D40 thinks the subject is in motion, because the D40 will automatically be tracking the subject. Now if I grab the Sigma's manual focus ring, I'll get manual focus for a moment, and then the D40 will take over again and continue to autofocus.

canon users won't know what you're talking about. because the usm lenses are not as good of a manual focus lens as nikkor swms are.

if you grab the focus ring in af-continuous mode with canons, the camera will still AF even if you turn the ring (you'll actually feel the mechanism slide under the ring). with nikon's swm, the lens knows you grabbed the ring and immediately cut off AF and only resume when you start it again with the af-on or release and half press the shutter again.

i suspect the sigmas are built with canon's style of AF

Rear AF button for autofocus + FTMF lens + Continuous AF = NO NEED TO EVER CHANGE A MODE. Single point AF? AF, let go. Manual focus? Turn ring, don't press AF button. Tracking something? Sit at your computer looking at a UPS webpage refreshing every five seconds. Uh I mean hold down the AF button...

This (possibly including the UPS part as well ). Back button AF is the best. Ever since I switched to it, I can't go back to shutter button AF.

So a guy I know asks me this on FB:

Quote:
my little bag is getting too small ): needing camera backpack something that could possibly hold two, three tripods as well? Alot of pocket AND space compartments!
I ask him about his budget and uses, and he said:

Quote:
Any budget. I hope bags don't go for more than $150....but space for flash units. Bout 5-6 future lens. Point and shoot. My camera body. And tripods for the flash units. Need the space now cause cramped and for future camera gear.
And this is coming from a guy who takes photos like these:







I'm not sure if I should feel annoyed but I do right now.
