蓝天，黄草，老车，很有秋天萧瑟的感觉，后面的两张火红的树，秋的热烈

俺这里雨多，叶子颜色斑驳不纯，只有欣赏距离美

正是这个地方。这个周末是长周末，昨天到那里去玩了一下午。

我拿白桦树跟你的狮子换吧，要不那个非洲海雕也行。

你的镜头用的是100-400/Mk2，你的相机用的是什么？我就是想知道跟踪对焦怎么样。

好啊，上次去加拿大都是07年了。
太想念Banff了

机身用的5D3 放到AI Serve
小部分情况需要在preset case 4，5，6 里面稍微选择一下
数量取胜还是王道：）

Tracking Sensitivity. Controls focus when another object intrudes on the subject you're tracking. When you get your focus on a bird and another object gets between you and the bird as you track it, should you stay with the original subject (-1,-2), or jump to the interfering one (+1,+2)?  A minus tracking sensitivity tends to stick with the bird while a plus goes with the intervening flock.

Acceleration/deceleration. The speed that birds that change speed, whether it be faster or slower. A duck comes at you, spreads its wings, decelerating to land (+1,+2). A medium-sized bird at 20 mph, or a small bird, flying at a little bit of an angle toward you, a +1 should return more keepers.

AF point Auto Switching. This control only applies if you’re using one of the Point Expansion or Zone (multiple focus points) Area Selection Modes. It’s not available if you’re using Single Point AF.  It sets how rapidly the AF point switches to a new AF point. Say you lock on a bird, and it banks and moves off as you’re firing. A +1 or +2 tells the camera to change focus points and stay on the bird. Best used with 61-point automatic selection AF, to give you the whole range to switch to. At first, the camera wasn’t reacting fast enough for me. I now think AF point Auto Switching is useful, and may be the ticket on select tough shots.

A look at the six preset Cases and what they might be good for.
Case 1 - Versatile multi purpose setting: 0,0,0. Adequate for larger birds in flight in open terrai, not flying right at you. The camera gets on the bird and stays with it if you stay on the bird. A good general setting.

Case 2 - Continue to track subjects, ignoring possible obstacles: -1,0,0. Example 1: When you’re locked onto a bird as it gets behind a floc, and you want to stay on the original bird. Example 2. A medium-sized bird in a thicket where you want the camera to ignore interfering branches as you follow a birds movement.

Case 3 - Instantly focus on subjects suddenly entering AF points: +1,0,0. You’re photographing a flock so it would make sense to pick up the closest birds as you usually want the closest thing to you to be in focus. Another scenarios is that you're on a bird and another nearby one flies in front of it, here it would make sense to switch focus to the near bird rather than the one now further away.

Case 4 - For subjects that accelerate or decelerate quickly: 0,+1,0. A large or medium bird coming right at you, coming in for a landing, taking off or buzzing by fairly quickly. An example would be where a bird leaps off the water, flies at you, and spreads it wings to land.

Case 5 - For erratic subjects moving quickly in any direction: 0,0,+1. Best for birds that change direction quickly such as leaping off a perch.  Works well with 61-point AF expansion, and non-busy backgrounds. Best shot for this setting is to have the bird at a far left or right AF point in anticipation of it flying into the frame.

Case 6 - For subjects that change speed and move erratically: 0,+1,+1. Best for small birds that change direction quickly while in flight.

好家什啊！我只有5D2和1D4，没有你这些custom setting。呃，其实我也没有好好看过，应该查一查了。就记得auto switching AF point很慢，所以索性锁定到中央点固定了。
