快門聲好實...
重手..
明天如果有時間給我看... manual....
want to try the spot AF, single-point AF and the zone AF
So far test 3 shots, the single-point AF is right on

作者: lsman1 時間: 2009-11-12 05:38
still not able to get use to the AF yet
set to AF zone of middle and just point and shot. most are not in focus. (if its 40D 100% of them will be un-useful for sure)... so may be the lens or my skill not there yet.
1/500 fast enough for bird? no idea ...first time or so.
crop about 1/4...
one 'viewable'

Tomorrow work from home.. so hopefully Friday I will have the 70-200 and 100-400 to play outdoor. Today only has 24-105 and 85 1.8 with it.

Don't play with the bird la, try simple focus test first. Shoot static objects to check if getting consistent AF accuracy. More and more ppl having their 7D returned.

yeah, surprising many post "need to have Canon service their AF problem" .
I test 3 shots at the night I got it... and next morning at office. center points are very fast, the side on sometimes "searching" and can't focus (I use left point only and focus my shoe under table....LOL. too much to ask?
)But the focus look right on on LCD.
One thing about 40D is on LCD, it seems okay but I always get a surprise (the bad one) once I back on computer and found it out of focus.
Same thing still in 7D (during those birds test). But I will give it as "I have not get use to this/ too high hope for a P&S bird"

One thing mention is a few review site is the diffraction factor.
(DLA)
People calculate on 7D, you may see a softer image at f/7
and 5dmk2 about f/10

F7.1係我常用的光圈，如果係真的話，咁7D弱左啲喎，唔啱我啦

This is an expected issue. With a 7D sensor that is more densely packed (than 5DII) in the center of the lens, diffraction from the lens is easier to be captured than that in 5DII.

That's why its a sports/bird camera...
and look like need to dial up the sharpness according to the digital-picture review.
Not a landscaping (-> 5Dmark II) camera.

imo, nikon's top bodies hold tracking much better than canon's top bodies.
some from today :P

totally back lit

Nikon's 51 points dynamic 3D tracking is stronger than Canon's 45 points AI SERVO.

當個人技術相近, 相機既機能就變成決定性影響
Canon 真係要稔稔計
